Frequently Asked Questions
Q: Which electric pallet trucks does the GWK-PMW20-LW fit?
A: The GWK-PMW20-LW is designed for the BYD PMW20 electric pallet truck. It is also compatible with Crown models that share the PMW20 specification. Do not assume compatibility with other BYD or Crown models. Always verify your truck model before ordering to prevent return freight and downtime.
Q: What are the wheel specifications for the GWK-PMW20-LW?
A: The GWK-PMW20-LW uses 9 inch diameter x 3 inch width polyurethane load wheels with 95A durometer hardness. Wheels are rated for 4400 lbs at a 24 inch load center. Sealed ball bearings prevent water and debris ingress, which is critical for electric equipment operating in damp warehouse conditions.
Q: Does the GWK-PMW20-LW work with 24VDC systems?
A: Yes. The GWK-PMW20-LW is specified for 24VDC electric pallet jacks with 130 Ah nominal battery capacity. The load wheel kit itself does not interact with the electrical system, but the truck it is fitted to must be 24VDC to ensure all components work correctly. Do not attempt to use on 36VDC or 48VDC systems.
Q: How do I diagnose if my PMW20 load wheels are worn out?
A: Inspect wheels for flat spots, cuts, or hardened areas that prevent smooth rolling. If wheels are worn 1/2 inch or more below 9 inches diameter, replace them. Test for bearing wear by spinning the wheel by hand. Rough rotation, grinding sounds, or lateral play indicates bearing failure. Worn wheels reduce truck speed, increase motor strain, and shorten battery run time.
Q: Does the GWK-PMW20-LW kit include fasteners and bearings?
A: Yes. The kit includes sealed ball bearings, axle, and fasteners. This is a complete plug-and-play replacement. You do not need to order separate bearings or hardware. Installation requires basic socket and wrench tools. Consult your PMW20 service manual for torque specifications on fasteners to prevent over-tightening and bearing damage.
Q: What charging time and battery specifications apply to the GWK-PMW20-LW equipped truck?
A: The PMW20 system uses 130 Ah nominal battery capacity with a full charge time of 4.5 hours from empty. The load wheel kit does not affect charging or battery performance. Ensure the truck charger is compatible with flooded lead-acid or AGM batteries as specified for your PMW20. Worn load wheels do increase battery drain by creating rolling resistance.
