Frequently Asked Questions
Q: What equipment models does the 4609399 load wheel fit?
A: The 4609399 is designed for direct fitment to Hyster electric pallet jacks, specifically W40Z and W45Z models. This is a load wheel assembly that supports the lift platform and load. Factory-spec dimensions are 3.25 inches diameter by 4.5 inches width. Verify your pallet jack model and serial range before ordering.
Q: What material and hardness is the 4609399 wheel made from?
A: The 4609399 is constructed from abrasion-resistant polyurethane (poly) compound at 95A durometer hardness. The 95A specification indicates a rigid compound suited for general warehouse use on concrete floors. Polyurethane resists wear better than rubber and handles moderate impact effectively. The wheel includes a stainless steel bearing and string guards for added durability and corrosion resistance.
Q: What bearing is used in the 4609399?
A: The 4609399 includes a stainless steel bearing designed for electric pallet jack load wheel applications. Stainless steel bearings resist corrosion in wet or humid warehouse environments and cold storage areas. The assembly comes with string guards to protect the bearing from debris and fiber accumulation during operation.
Q: Is the 4609399 suitable for high-duty-cycle or wet floor operation?
A: The 4609399 is designed for poly-tread electric pallet jacks in high-duty-cycle warehouse environments. The 95A polyurethane compound performs well on standard warehouse floors with frequent lifting and lowering. For extended wet floor or cold storage use, consider wheels with higher traction compounds or consult specifications for your specific floor conditions.
Q: What is the typical lifespan of the 4609399 load wheel?
A: Load wheel lifespan typically ranges from 24 to 48 months depending on operating hours, floor type, and load patterns. High-duty-cycle environments, wet floors, or rough concrete may reduce service life. Inspect wheels regularly for flat spots, cracking, or polyurethane delamination. Replace when wear exceeds approximately 10 percent of original diameter.
