Frequently Asked Questions
Q: What is the PR 40721-00 load wheel used for?
A: The PR 40721-00 is a load wheel (non-drive wheel) designed for electric lift trucks. Load wheels support the weight of the lifted load and guide the truck on smooth warehouse and production floors. They are installed on the non-drive axle positions.
Q: Which electric lift truck models is the PR 40721-00 compatible with?
A: The PR 40721-00 is designed for Prime Mover electric lift trucks and may be compatible with comparable models from Crown, Toyota, Raymond, Yale, and Hyster. Verify your lift truck model, serial range, and axle bore diameter before ordering to confirm correct fitment.
Q: When should the PR 40721-00 load wheel be replaced?
A: Replace the PR 40721-00 when the wheel shows flat spotting, cracks, chunks missing, hardening, or significant wear that reduces floor contact and traction. Worn load wheels cause uneven tire wear on the drive wheel, reduce maneuverability, and may indicate bearing wear.
Q: Do load wheels wear faster than drive wheels?
A: Load wheels and drive wheels wear at different rates depending on material hardness and load distribution. Load wheels typically experience continuous weight support and wear gradually. Drive wheels experience higher friction and often wear faster. Inspect both wheel types at regular maintenance intervals to minimize downtime.
Q: What material is the PR 40721-00 load wheel?
A: The PR 40721-00 is manufactured from industrial-grade rubber or polyurethane designed to support continuous load without deformation. Material hardness and compound selection determine floor performance, traction, noise level, and wear life under typical lift truck duty cycles.
Q: Can the PR 40721-00 be used in cold storage or on wet floors?
A: Standard load wheel rubber can harden in cold storage environments below 40 degrees Fahrenheit, reducing traction and increasing slippage risk. If your application includes cold storage or frequent wet floor operation, verify material specification or contact us about alternative compounds designed for those conditions.
