Maintenance

As a utility fleet professional, you’re well-versed in ANSI’s requirement for annual dielectric inspections on aerial equipment to verify the nonconductivity of electricity through the boom. These inspections help you and your team identify and fix potential issues before they can cause injury or downtime.

But if you have bucket trucks, digger derricks and other aerial equipment spread across several locations and regions, how do you ensure those critical inspections are getting done on time, according to the right standards and at the best possible price?

That’s the challenge John Adkisson confronted in April 2019 when he became the director of fleet services at Asplundh Tree Expert LLC, the Willow Grove, Pennsylvania-based company that provides vegetation management and utility infrastructure services to utilities and municipalities throughout the U.S., Canada, Australia and New Zealand.

When operating heavy lifting equipment, like forklifts and cranes, there should be no one underneath the lifted load.

But there is one exception to that rule: automotive lifts.

“The automotive lift industry is the only one where operators are encouraged to go underneath a lifted load,” said R.W. “Bob” O’Gorman, president of the Automotive Lift Institute (www.autolift.org), a trade association of North American-based lift manufacturers that promotes the safe design, construction, installation, service, inspection and use of automotive lifts.

"For every other type of lifting equipment out there, the message is clear: 'Don't do it. Don't get under that load.' But in the automotive lift industry, the message is, 'Go forth and perform your job with 10,000 to 50,000 pounds above you,'" O’Gorman said. "That's why choosing the proper lift is so important – so that operators can feel comfortable in performing their jobs under such capacities."

Winters in the northern latitudes can be brutal. A utility fleet’s winter preparedness plan for the maintenance shop can improve safety for its technicians and helps to ensure that fleet equipment is ready to go when needed.

UFP spoke with Les Faul, operations manager with Commonwealth Edison Co., to find out how the Chicago-based utility has kept its 22 maintenance shops operating during winter. This was the second of two recent UFP interviews with Faul about utility operations.

UFP: What does winterizing a maintenance facility entail?

Les Faul: There are a few things that we do. Beginning in October, we have a winter preparedness plan that assigns certain corrective actions to different organizations. In the shop, we increase our stock of high consumables, such as snow brushes, scrapers, wiper blades, filters – those winter items.

Matt Gilliland, director of operations support for Nebraska Public Power District (NPPD), understands the value of investing in training for fleet mechanics.

“There is an old cliché that says, ‘The only thing more expensive than training is not training,’” he said. “Training is one of the most important tools in the technician’s toolbox.”

And it’s even more so these days in an industry that, according to Gilliland, “changes rapidly, and the technology within the industry grows ever more complex. Training is paramount for success.”

To stay on top of changes with OEM specs, NPPD sends its fleet team to training on an ongoing basis. That, said George Survant, senior director of fleet relations for NTEA – The Association for the Work Truck Industry (www.ntea.com), is necessary today.

Making sure your shop is well-stocked to handle any issues that come your fleet’s way is a smart plan, but it also can be costly and inefficient if you overdo it and end up with bloated inventory. UFP recently spoke with two fleet professionals who shared some best practices about how to operate a more balanced and efficient parts management program.

The best starting point is to monitor what moves and then find a sensible minimum, according to Dale Collins, fleet services supervisor for Fairfax Water in Virginia.

“Maintain an inventory of items that move quickly and be sure that your suppliers are able to provide quick sourcing of less frequently used items,” he advised, noting that mission-critical parts are important to have in-house.

For Fairfax Water, consumables – including fluids, filters, brakes and tires – are the most important. The majority of other items can be sourced quickly, Collins explained.

More vehicles with advanced driver assistance systems (ADAS) are showing up in utility fleet maintenance shops as vehicle manufacturers accelerate the introduction of these safety technologies into new models.

While there is little doubt that ADAS features – such as adaptive cruise control, radar-based collision avoidance systems and other technologies – can lower fleet costs by improving safety and reducing collisions, the issue for fleets is what effect these components will have on maintenance. Will these technologies increase maintenance costs by requiring more training or new equipment?

The early answer from fleet and industry consultants is that it is too soon to know definitively. Much depends on which components and features the fleet adds. In some cases, the technologies build on well-known foundation systems, so the need for training or additional equipment may be minimal, one supplier said. Some technologies, like radar, self adjust.

“Right now, it’s truly unknown what the expectations are,” said Darry Stuart, principal with DWS Fleet Management (www.darrystuart.com), a maintenance consulting firm. “It’s going to be challenging in the early days until it’s figured out.”

San Diego Gas & Electric added 10 small SUVs with adaptive cruise control, lane departure warning and emergency (crash avoidance) braking systems in early 2018. It’s still early, but so far results in the shop have been good, said Clint Marsh, fleet asset manager. “Maintenance for the radar-based systems is minimal and has not affected maintenance/parts costs for vehicles with this technology.”

Prior to purchasing a new vehicle lift, a fleet manager must understand exactly what is needed for their shop.

According to Steve Perlstein, sales and marketing manager for Mohawk Lifts (https://mohawklifts.com), fleet managers “need to do their homework in order to make an educated decision.”

So, what are some of the most important items to consider? UFP recently spoke to vehicle lift experts to find out.

Identify Your Needs
Maintenance is among the top factors fleet managers should think about before they buy, advised Doug Spiller, heavy-duty product manager for Rotary Lift (www.rotarylift.com).

“The best lifts will require minimal maintenance while offering years of safe, reliable service,” he said. “One of the first questions a fleet manager should ask themselves is, what vehicle maintenance am I going to perform, and will this lift help me do that faster, better and easier than I do it today?”

Winter is just around the corner, and it often brings with it less-than-ideal operating conditions for utility fleets in many parts of the U.S. and Canada.

UFP recently spoke with two industry professionals who shared some best practices for keeping operations up and running while facing harsh weather conditions including snow, ice and freezing temperatures.

Start Preparing Early
For many utility fleets, the biggest challenge during the winter season is keeping vehicles and equipment in peak operating condition to avoid unforeseen downtime when those units are needed most. Heavy use during emergent situations often results in unscheduled repairs and breakdowns – or worse yet, accidents, according to Charlie Guthro, vice president of global strategic services for fleet management company ARI (www.arifleet.com).

Michigan-based DTE Energy, which operates a fleet of more than 5,000 assets ranging from automobiles and SUVs to bucket trucks and construction equipment, experienced its snowiest month in January 2014, with 39 inches of snow. During that same winter, Southeast Michigan experienced 77 straight days with at least 1 inch of snow on the ground.

“Because of the snow, ice and colder temperatures, our challenges include an increased number of no-starts, de-icing windshields, door locks icing, increased towing and service calls, and increased response time due to icy and snowy roads,” said Mike Homan, DTE’s director of fleet.

Outsourcing preventive maintenance and unscheduled repairs on light-duty units can help utility fleets minimize downtime and focus on the more complex mission-critical and specialized equipment in their operations.

It’s easy to rent a car or pickup truck if a light-duty asset is in the shop or down for a long period of time, explained Paul Jefferson, fleet manager for OG&E Fleet Services in Oklahoma. “Bucket trucks, trenchers [and] line trucks are a little more difficult to rent. We have tools and materials on pieces of equipment like that, so we can do maintenance in-house and control the timeline of the work,” he said.  

Keeping services in-house rather than outsourcing them also can help to ensure that safety remains a top priority when working on these assets.

“The utility industry as a whole requires a very high level of safety training, and this education extends to the in-house technicians,” said Charlie Guthro, vice president of global strategic services for fleet management company ARI (www.arifleet.com).

But if fleets determine they need to outsource some of their work, how do they make the most of it? UFP recently spoke with several industry experts who shared their tips, including mistakes to avoid.

Running a successful utility fleet operation requires fleet managers to, among other things, stay on top of any and every aspect of the business that will impact total operating costs.

A fleet’s tire program is one aspect that makes a significant impact. According to Gary Schroeder, director of global truck and bus tire business for Cooper Tire & Rubber Co. (http://coopertrucktires.com), tire programs are the second-highest operating cost – behind fuel – for the majority of fleets.

So, what can utility fleets do in an effort to control those expenses?

“Helping fleets understand their total tire operating costs – and the role that tires can play in reducing these costs – is important,” said Dustin Lancy, marketing manager for The Goodyear Tire & Rubber Co. (www.goodyear.com). “Some fleets consider tire price to be the driving factor, but we urge them to look beyond the upfront cost of a tire and instead … optimize the return on their tire investment.”

Focus on What Matters Most
Keeping tire costs in check requires a tire program that includes proper tire selection, timely maintenance and frequent inspections.

Fairfax Water, a utility headquartered in Fairfax, Virginia, maintains a selection of tires and tire/wheel assemblies at each of its maintenance facilities, replenishing as needed. Light-duty tires are mounted and balanced in-house, while the tire/wheel assemblies for the fleet’s larger heavy-duty trucks, trailers and equipment are sent out for servicing.

With more baby boomers heading into retirement, industries that have benefited from these individuals’ decades of experience and expertise — including the utility fleet sector — are now left to hire and retain new talent.

That won’t be easy, according to Jennifer Maher, CEO and executive director of TechForce Foundation (www.techforcefoundation.org), whose mission is to champion students to and through their education and into careers as professional technicians. “There has been a critical shortage of qualified technicians for at least 20 years, so as the rest of the baby boomers retire within the next 10 years, things can only worsen. A report that we published late last year indicated that for this year alone, the vehicle industry – auto, diesel and collision – needs more than 137,000 new-entrant technicians.”

But it’s not just the retirements that will make matters worse, Maher said. “There simply are not enough young people seeking a technician career by any means – formal or informal education and training – to fill the void. Our school systems in this country have either reduced or eliminated vocational training in favor of a four-year degree. In effect, they have abandoned working with your hands as a viable career path, which is absurd not only because of the tech shortage, but also because a tech career offers a solid, middle-class lifestyle.”

So, what can utility fleets do to address this problem – and what should they opt not to do?

When selecting a new maintenance bay lift that’s safe for your fleet operation, there’s more to consider than the assets that will be lifted on it. It’s also essential to account for what will be under and above the lift – and how the weight will be distributed.

All too often, industry experts say, well-meaning fleet professionals and maintenance technicians choose a lift simply based on the weight of the largest vehicle or piece of equipment it will hold. But there’s more to the equation, and getting it wrong can have disastrous results.

First, noted George Survant, senior director of fleet relations for NTEA – The Association for the Work Truck Industry (www.ntea.com), it’s important to remember that the base weight of an asset is one thing, but the weight of that asset when it’s on the lift, fully loaded, is another.

Here are seven additional considerations from Survant and Steve Perlstein, president of auto lift supplier Mohawk Lifts (www.mohawklifts.com), on choosing a lift with safety in mind.

In some parts of the country, the leaves are already changing color and there’s a nip in the air. Fall is here and winter is not far behind, which means time is slipping away for utility fleet managers to winterize their fleet assets before truly cold weather sets in.

Forgive Tom Jansen, superintendent of fleet maintenance for Minnesota Power, for being nonchalant about the impending weather. Despite the harsh winter conditions in Minnesota – home of four of the country’s 15 coldest cities, according to USA Today – Jansen’s fleet is prepared for whatever Mother Nature might throw at it. Cold? Bring it. Ice? Ready. Winter Storm Colbert, which The Weather Channel announced would be the third named storm of the coming season? He laughs.

For Jansen’s 600-unit fleet – which includes Class 3-8, off-road and mobile assets – winterizing isn’t contained to a few months of the year. “While there are activities performed just prior to winter to help the fleet stay operating effectively, we’ve found success with focusing on a good year-round preventive maintenance program, purchasing practices and operator training,” he said.

That means using oils and lubricants that are effective throughout the year, installing solar battery chargers on all new trailers and off-road equipment, and ensuring that equipment purchased has block heaters and battery disconnects. The result: a reduced winter preparation workload.

Even if you have a robust in-house repair shop, chances are that you still outsource portions of your maintenance operations – to save money, quickly fill gaps left by technicians who’ve recently retired or tap into specialized expertise to perform critical repairs.

But how do you determine which aspects of your maintenance operations make the most sense to outsource and which ones you should keep in-house?

UFP recently posed this question to Paul Lauria, who has worked with numerous government and utility fleets for more than three decades as president of Mercury Associates Inc. (www.mercury-assoc.com), a fleet management consulting firm based in Rockville, Md. He offered these four points to consider.

1. Cost
How much money will outsourcing actually save the organization?

“The only way that you're going to be able to determine if you're saving money is to know the costs of performing outsourceable fleet maintenance and repair activities in-house versus farming them out to a vendor or contractor,” Lauria said. “And that's one thing, in my experience, that a lot of organizations, including utilities, don't have a good handle on. What are the avoidable costs of operating its own garages or of performing a particular type of maintenance or repair activity, for example? If you were to shut down or downsize those garages and shift work to third-party service providers, what costs would go away? That establishes the baseline for determining whether or not you can save money by outsourcing.”

As a utility fleet manager, you operate perhaps the most diversified vehicle fleet of any business, typically using all weight classes of trucks, from light- to heavy-duty, on the road and off, hauling aerial devices, digger derricks and a slew of other job-specific equipment on good pavement or through fields of debris.

Given these characteristics, getting the best value and performance from your tires may not be rocket science, but it does take planning, smart spec’ing and commitment to a maintenance program, according to tire manufacturers.

A fleet’s first step toward tire value is to determine its goals, said Bill Walmsley, product category manager with Michelin Americas Truck Tires (www.michelintruck.com). What do you want in your tires? Durable, trouble-free service and long, even wear? Additional features? Regardless, selecting the best tire for the application is key. Walmsley suggested that fleets start by looking at the same tire size they currently have on their equipment by wheel position and then explore available options in that size to meet the specific conditions under which the equipment will operate. “This might entail specific load-carrying requirements, weather conditions or environmental issues, such as off-road products or tires which operate well in field or snow conditions,” he said.

Calibrating the balance between load and appropriate tire pressure is critical, but it also is easy since every tire manufacturer publishes load and inflation charts for their tires. The only way to make sure the calibrations are correct is to know the loads being carried and use the charts, Walmsley said.

“Tires are designed and optimized to carry a desired load at a specified pressure. Proper pressure for the maximum load being carried is very important. Underinflation and overinflation for the loads being carried will affect tire and casing life and performance,” Walmsley said.

Manufacturers have stepped up their technology efforts to meet rigorous fuel-efficiency and emissions standards. In doing so, many next-generation engines will need higher-performing diesel engine oils to protect them. This requires changes in engine oil composition to withstand more heat without sacrificing engine protection.

A new generation of diesel engine oils was rolled out in December 2016. One of those oils is CK-4, a high-temperature, high-shear (HTHS) oil that can be used in both new and existing engines. It is available in the same viscosity grades and oil types currently being used in fleet operations.

According to the American Petroleum Institute (API), CK-4 can be used in high-speed, four-stroke-cycle diesel engines designed to meet 2017 model-year on-highway and Tier 4 non-road exhaust emission standards, as well as previous model-year diesel engines.

As much as possible, minimize exposure between new and old engine oils to ensure the benefits of CK-4 as well as continued OEM warranty support, advised Mark Betner, heavy-duty product line manager for CITGO (www.citgo.com).

A second oil type that debuted in December – FA-4 – has limited backward compatibility and is better suited for 2017 model-year engines and beyond. This “low-HTHS” oil is offered in lower viscosity grades and is not recommended for use with fuels having greater than 15 parts per million sulfur, according to API (www.api.org).

What Are the Benefits?
Benefits of the new CK-4 and FA-4 oils include increased fuel economy and lower emissions.

“Lower-viscosity engine oils will improve fuel economy and reduce greenhouse gases over [previous] engine oils,” Betner said. “FA-4 engine oils in an FA-4-compliant engine will offer even greater fuel economy and reduce greenhouse gases.”

In addition, “Today’s lighter weights can deliver the equivalent or even better wear protection than a CJ-4 15W-40 oil, along with significantly improved oil drain performance,” according to Len Badal, global Delo brand manager for Chevron Lubricants (www.chevronlubricants.com).

Betner agreed, noting the advanced technology of these two engine oils provides significant improvements in deposit control, shear stability and oil aeration control. “These engine oils will also have a 60 percent better oxidation resistance compared to API CJ-4, which aids in extended service intervals,” he explained.

Badal mentioned that off-road equipment would reap significant rewards from CK-4. “CK-4 oils deliver many benefits that directly address major issues with off-road equipment, including extended drain intervals, reduced engine wear and ability to extend rebuild intervals,” he said. “Off-highway equipment operators stand to gain a lot of benefits from the new API CK-4 oils, with a direct impact on reliability, productivity and profitability.”

Based on reduced fuel consumption, and extended oil drain and engine rebuild intervals, potential cost savings are expected.

Fleets surveyed by CITGO reported improved fuel efficiency after converting to its new API CK-4 oils, with improvement ranging from 1.6 to 3.2 percent after 50,000 miles.

What’s the Next Step?
Identify the units in your fleet that will be most impacted, and always check the owner’s manual for the proper lubricant recommendation.

One particular area of concern is for fleets comprised of various makes and models. Some automakers have indicated that neither one of the new engine oils should be used in certain vehicles at this time.

Nebraska Public Power District is one utility that has been proactively addressing that issue. Matt Gilliland, NPPD’s director of transportation and facilities, said he has been communicating with internal staff and servicing vendors to address the diversity of units in the organization’s fleet.

OEM Specs for API CK-4 and FA-4 Oils
Major diesel engine and truck manufacturers recently provided their own OEM specifications that connect with the new API CK-4 and FA-4 categories for their new model GHG 2017 diesel engines, with several also citing backward compatibility as well as upgrades to support longer oil drain intervals. These initial specs are mainly focused on CK-4 but should include more FA-4 data in the future.

As Dale Collins, CAFM, has rightsized his fleet in recent years, the fleet services supervisor for Virginia-based Fairfax Water has discovered the need to rightsize his maintenance bay lifts as well.

When the vehicle maintenance facility was built, the fleet had a higher percentage of heavy-duty dump trucks and crew vans, so the emphasis was on lifts that could handle their 60,000-pound weight. These days, however, Collins can service 80 percent of his fleet with more efficient 12,000-pound-capacity cassette lifts.

“Anybody who is in the market for a lift has to know what it is they’re trying to lift, how much it weighs and what the lift’s wheelbase limits are – not only how small it will get, but how long you will need it to be,” Collins said. “A lot of times you can get into a jam with longer vehicles.”

Collins speaks from experience; one Freightliner in the utility’s fleet has a 328-inch wheelbase. But the fleet department was able to work with the lift manufacturer/distributor to secure lifts that can handle anything from the Freightliner down to the 125-inch wheelbase of a Ford Ranger pickup.

This story highlights a potential error some fleet managers make when choosing lifts: assuming that they are one size – or one style – fits all. Collins now has a diversified set of lifts for his diverse fleet, including a telescoping piston lift for heavy-duty assets as well as an in-ground scissor-type lift that utilizes only 7 gallons of fluid to operate.

A 70-inch snowfall in Buffalo, N.Y. A polar vortex. An ice storm in the South. The last few winters certainly have been memorable, and this coming season looks to be more of the same. The National Weather Service’s Climate Prediction Center (www.cpc.ncep.noaa.gov) is forecasting below-normal temperatures for much of the U.S., with some locations experiencing more precipitation than average.

While this may be good news for skiers and those who like to build snowmen, it can wreak havoc for utility fleets – those pressed to keep services operating no matter the weather.

“When you’re in our business, the power has to be on 24/7,” said Michael Donahue, manager of transportation and construction equipment for Omaha Public Power District (www.oppd.com). “The crews and vehicles and equipment have to be ready to respond for normal maintenance and when there is an emergency.”

Given that the average high temperature in Omaha, Neb., hovers around the freezing mark during the winter months, winterizing the utility’s fleet is a given. Historically, the OPPD fleet maintained its 1,000 licensed vehicles and 300 pieces of construction equipment by issuing preventive maintenance orders each September 1. “But what that did was put 1,000 PMs due on our list,” Donahue explained. Now the fleet garage incorporates winterization into the normal maintenance schedule. “It eases up on the guys in the shop and the crews, too,” he said.

Deciding whether to outsource maintenance and repair work or perform it in-house can be a daunting task for fleet managers. To gain some industry insight, UFP recently spoke with Holly Giffrow-Bos, fleet supervisor for East Central Energy (ECE), and Dan Remmert, manager of fleet services for Ameren Illinois Company (AIC), about what’s worked for their operations and what to consider if you’re leaning toward outsourcing part or all of your maintenance and repair work.

According to Giffrow-Bos, about 15 to 20 percent of ECE’s fleet jobs are outsourced. These typically include body work, warranty work and any kind of heavy-duty engine or transmission replacement work. The electric distribution cooperative, headquartered in Braham, Minn., has a fleet of approximately 180 units.

Due to the level of training and the resources required to perform body work, Giffrow-Bos said ECE “never got into it because of the expense of having that specially trained person and equipment.” The fleet also doesn’t have a lot of jobs that require body work.

In general, ECE handles all diagnostics, repairs and preventive maintenance in-house. This work, too, comes at a significant expense; each of the cooperative’s in-house technicians must be trained on all vehicle makes and models used by the fleet, as well as a range of different tasks.

Are you unsure whether to purchase aftermarket or OEM replacement parts for your fleet’s vehicles? Using a mix of both has proven to be an effective strategy for Ameren Illinois Company (AIC), Fairfax County Water Authority (Fairfax Water) and Oklahoma Gas & Electric (OG&E), according to fleet representatives from the three utilities.

Safety, performance, availability and quality are among the factors that make OEM parts the best option for certain aspects of fleet operations.

“On critical components, it’s better to get the original equipment parts instead of taking a chance on questionable quality of the aftermarket materials,” explained Dale Collins, CAFM, fleet services supervisor for Virginia-based Fairfax Water, which maintains more than 400 fleet units. “Folks can easily replicate good-quality wiper blades, but not more sophisticated electronic parts.”

Several years ago Fairfax Water replaced the original brake pads on its heavy-payload pickup trucks with aftermarket pads that did not hold up well. The utility now relies on the durability of factory OEM brake parts that they have found to be superior to aftermarket products. Fairfax Water also depends on original equipment parts for engine management due to past performance issues with some of its construction equipment, and it uses OEM parts for auto body and crash repairs in critical areas of the vehicle in order to maintain “crashworthiness,” or the ability of a vehicle to protect occupants during an impact.
