Frequently Asked Questions
Q: What are the dimensions and material composition of the CR 088628-A?
A: The CR 088628-A is a 4 x 4.125 inch load wheel featuring a polyurethane tread with 95A durometer hardness bonded to a steel core. The polyurethane provides traction and shock absorption, while the steel core gives structural support for heavy load handling on Crown electric lift trucks and pallet jacks.
Q: Which Crown equipment models is the CR 088628-A designed for?
A: The CR 088628-A is compatible with Crown RR RD 5700 Series Reach Truck pallet jacks. Verify your equipment serial number and reach truck designation match this compatibility before ordering. Cross-compatibility with other Crown models or brands requires confirmation of bore, diameter, and mounting configuration.
Q: What does a 95A durometer polyurethane provide compared to softer or harder compounds?
A: The 95A durometer polyurethane offers a balance between traction and wear resistance. It is firmer than 92A compounds, providing better load support and reduced tread deformation, while remaining softer than 97A compounds for improved floor grip and shock absorption in material handling environments.
Q: What is the advantage of a steel core construction?
A: The steel core provides radial strength and prevents the wheel from collapsing under heavy or sustained loads. Steel cores maintain dimensional stability over the life of the wheel and resist permanent deformation from concentrated weight, which is critical for electric lift trucks handling dense pallets in reach applications.
Q: How does the 4 x 4.125 inch size affect performance on reach trucks?
A: The 4 inch diameter and 4.125 inch width provide a compact footprint suitable for the steering and load wheel requirements of reach truck design. This size supports maneuverability in narrow warehouse aisles while maintaining adequate load-carrying capacity for pallet handling operations.
