Frequently Asked Questions
Q: What are the exact dimensions of the CR 312021-003-A load wheel?
A: The hub is machined steel with polyurethane bonded tread and shoulder bearing construction. Confirm these dimensions match your Crown 300 Series equipment specifications.
Q: What does Shore 97A hardness mean for this load wheel?
A: Shore 97A indicates a firm polyurethane compound that resists cutting and abrasion in heavy-duty environments. This hardness rating is ideal for long runs, heavy loads, dock boards, and floors with debris. Harder shore ratings provide superior wear resistance on rough surfaces.
Q: Which Crown lift truck models use the CR 312021-003-A?
A: The CR 312021-003-A is engineered for Crown 300 Series electric lift trucks rated for long-run and heavy-load applications. No cross-reference part numbers exist for this part. Confirm your equipment model and serial range match Crown 300 Series specifications.
Q: How long does this load wheel typically last?
A: Load wheel lifespan depends on floor conditions, load weight, and usage frequency. Polyurethane wheels like the CR 312021-003-A generally last 12 to 36 months in moderate to heavy-use environments. Monitor for uneven tread wear, flat spots, or reduced traction as replacement indicators.
Q: What makes Shore 97A polyurethane suitable for heavy-load applications?
A: The 97A shore hardness provides excellent durability and cut resistance while maintaining sufficient grip on various floor surfaces. This compound balances load-bearing capacity with operator safety and extended wheel life in warehouse and dock environments.
