Electric Stacker Wheels: Maintenance & Replacement Guide

Electric stackers are a big investment. They move heavy loads and can run for long hours, and lift pallets several metres in the air — so when a wheel starts to fail, the safety risk is real.

This guide covers what to check, when to check it, and when it's time to replace.

Drive Wheels vs Load Wheels

Drive wheels wear faster because the motor pushes power through them. Load wheels last longer but matter more for safety — if one fails while a pallet is lifted, the whole load can become unstable.

If your stacker has tandem load wheels (two load wheels per side), replace them as a set. Mixing a new wheel with a worn one causes uneven handling.

Daily Checks (30 Seconds Per Shift)

Every operator should run through this before starting a shift:

• Look for cracks, missing chunks, or flat spots on each wheel.
• Spin each wheel by hand — it should turn smoothly with no grinding or resistance.
• Listen during the first few minutes of use for squeaks, clicks, or grinding.
• Clear any debris stuck to the wheel or near the bearing.

If you see structural damage (cracks, missing chunks), take the stacker out of service immediately. Don't run powered equipment on a damaged wheel.

Weekly Checks

These take a bit longer but catch problems daily checks miss:

• Measure tread depth at several points around the wheel. Replace once the tread is noticeably worn or wearing unevenly.
• Check the mounting bolts — they loosen over time, and a loose wheel mount is dangerous.
• Look for uneven wear across the wheel face. This usually points to an alignment issue, not just a worn wheel.

Monthly Checks

Once a month, dig a little deeper:

• Check the mounting surface on the stacker for corrosion or damage.
• Test the brake system — on electric stackers, braking depends on good wheel-to-floor contact.
• Compare current measurements against past records to spot wear trends early.

Signs It's Time to Replace

Don't wait for failure. Replace wheels when you see any of these:

• Noticeable or uneven tread wear
• Cracks or missing chunks in the wheel body
• The stacker takes more effort to push or steer
• Wobble, vibration, or unusual noises during use
• Reduced lifting stability
• Operator reports of changed handling feel

What Wears Wheels Out Faster

You can extend wheel life by avoiding these:

• Overloading. Going over the rated capacity damages every wheel component.
• Rough handling. Hard starts, slammed stops, and tight fast turns multiply wear.
• Dirty floors. Concrete grit gets embedded in the wheel and acts like sandpaper.
• Chemical exposure. Oils, solvents, and cleaning agents attack some wheel materials.
• Temperature extremes. Standard materials go brittle in freezers and soften in heat.

Picking the Right Replacement Wheel

When you replace a wheel, match the material to your environment. AVM Diesel supplies Räder-Vogel wheels from Germany, with grades for different conditions:

• Standard polyurethane — the everyday option for most warehouse duty.
• Vulkollan (premium polyurethane) — for critical, high-load equipment that needs longer life and higher capacity.
• Hydrolysis-stabilized polyurethane — lasts much longer in humid climates like Singapore, Malaysia, and Hong Kong, where standard polyurethane breaks down faster.
• Vulkollan ELF (anti-static) — for areas with explosion or static-discharge risk.
• Cold-rated compounds — for freezer and cold storage.

Hardness is measured on the Shore scale — polyurethane is read on Shore A and harder plastics like nylon on Shore D. These are separate scales, so a reading on one can't be compared directly against a reading on the other. Softer wheels grip better; harder wheels last longer.

When ordering, the fastest way to get an exact match is your stacker's manufacturer part number. If you don't have it, send us these instead:

• Wheel diameter, rim diameter, and tread width
• Bearing-hole diameter and length
• For drive wheels: number of mounting screws, distance from the centre to the screws, and screw-hole diameter
• How and where the wheel is used

Replacement Procedure (At a Glance)

Drive wheel:

• Raise and support the stacker safely.
• Disconnect any electrical lines to the wheel motor or sensors.
• Remove the mounting hardware.
• Fit the new wheel to manufacturer torque specs.
• Test rolling, braking, and steering before returning to service.

Load wheel:

• Raise the forks and support the equipment.
• Access the wheel assembly from below.
• Remove axle pins or bolts.
• Fit the new wheel.
• Test under load before normal use.

Load wheels are simpler to swap, but the testing step still matters.

Keep Records

Good maintenance starts with good notes. For each stacker, keep track of:

• Wheel installation dates
• Operating hours at replacement
• Any wear patterns or issues noticed
• Brand and part number of the wheel installed

Over time these records let you predict replacements instead of reacting to failures — and that's where the real savings come in.
