Frequently Asked Questions
Q: What polyurethane hardness is the HY 4077399-XL wheel, and what does Shore 97A mean for material handling?
A: The HY 4077399-XL features a Shore durometer 97A polyurethane wheel. Shore 97A is a high-hardness compound that resists wear and deformation under heavy loads. This hardness level is typical for load wheels in electric lift trucks where durability and precision are required. The machined, non-marking surface prevents scuffing on finished warehouse floors.
Q: Which Hyster electric lift truck models accept the HY 4077399-XL load wheel assembly?
A: The HY 4077399-XL is engineered as an OEM-fit replacement for Hyster electric lift trucks. Verify that your equipment matches the wheel mounting diameter and riser height before ordering. No cross-reference or supersession part numbers are available for this assembly.
Q: Does the HY 4077399-XL include sealed ball bearings, and what is the benefit?
A: Yes, the HY 4077399-XL includes sealed ball bearings. Sealed construction prevents contamination from moisture, dust, and debris, extending bearing life and reducing maintenance downtime in warehouse and dock environments.
Q: What are integrated string guards on the HY 4077399-XL, and why are they heavy-duty?
A: Integrated string guards are protective features molded into the wheel assembly that prevent rope, strapping, and debris from tangling around the axle or bearing area. Heavy-duty construction on the HY 4077399-XL means these guards can withstand impact and repeated contact without cracking or breaking.
Q: Is the HY 4077399-XL suitable for wet or cold storage environments?
A: The machined polyurethane compound provides good traction and durability in standard warehouse conditions. For extended wet floor or cold storage use, verify environmental suitability with specification data for your specific application requirements.
