Frequently Asked Questions
Q: What are the exact dimensions of the CR 802800 load wheel assembly?
A: The CR 802800 load wheel assembly has a nominal outside diameter, a tread width, and a bore diameter. It features an integrated shoulder bearing type design for electric lift trucks and pallet trucks.
Q: What is the material composition and hardness of the CR 802800 wheel?
A: The CR 802800 uses Crown Compound 306 polyurethane with 97A Shore hardness rating. This formulation provides high load capacity and durability for standard indoor material handling applications on concrete and tile floors.
Q: Which lift truck models and brands does the CR 802800 fit?
A: The CR 802800 is a Crown factory-spec load wheel assembly designed for Crown electric lift trucks and pallet truck series. The 5-inch diameter and 2.44-inch bore fit Crown equipment. Cross-compatibility with other brands such as Toyota, Raymond, or Yale requires bore and mounting verification before ordering.
Q: How does the CR 802800 compare to the CR 802800-A?
A: Both are Crown load wheel assemblies with 5-inch outside diameter. The CR 802800 has a 2.88-inch tread width and 2.44-inch bore, while the CR 802800-A features a 4.12-inch tread width. The tread width difference affects load distribution and stability. Verify which matches your equipment before ordering.
Q: What is the expected lifespan of the CR 802800 wheel?
A: Lifespan depends on load weight, floor conditions, and hours of operation. Standard polyurethane compound wheels typically last 2 to 4 years in regular use. Rough floors, heavy loads, or extended cold storage exposure accelerate wear. Monitor tread depth and bearing play periodically.
Q: How should the CR 802800 be stored when not in use?
A: Store in a cool, dry environment away from direct sunlight and extreme temperatures. Excessive heat and UV exposure degrade polyurethane compound over time. For extended storage beyond 6 months, keep wheels in a climate-controlled area to preserve material integrity and performance.
