Frequently Asked Questions
Q: What are the dimensions of the CR-401 polyurethane wheel?
A: The CR-401 features a 3.25 inch outside diameter, 5.91 inch tread width, and 2.047 inch bore. These dimensions make it a replacement wheel for Crown electric lift trucks. Verify these measurements match your equipment before ordering to ensure proper fitment.
Q: What is the shore hardness rating of the CR-401 wheel?
A: The CR-401 is engineered with a 93A Shore hardness polyurethane compound. This hardness level provides durable load-bearing capability for sustained heavy-duty operations while maintaining adequate traction and floor contact characteristics typical of electric lift truck wheels.
Q: Which lift truck brands and models does the CR-401 fit?
A: The CR-401 is a Crown OEM polyurethane wheel (Manufacturer Part Number 310178-401) designed for Crown electric lift trucks. This wheel may also fit compatible models from Toyota and Raymond that use the same bore and diameter specifications. Verify your equipment model and serial range for compatibility confirmation.
Q: What is the CR-401 wheel compound designed for?
A: The CR-401 Compound 401 polyurethane wheel is engineered for heavy-duty, long-run operations on electric lift trucks. The polyurethane compound provides good wear resistance, load capacity, and floor protection compared to rubber alternatives.
Q: How long does a CR-401 wheel typically last in service?
A: Polyurethane wheel lifespan depends on equipment load capacity, operating hours, floor surface conditions, and maintenance practices. High-cycle operations and rough flooring accelerate wear. Replace when tread depth diminishes, flat spots develop, or wheel wobble becomes apparent.
Q: Does the CR-401 work on wet floors or cold storage areas?
A: Polyurethane wheels like the CR-401 operate in wet and cold storage environments, but traction characteristics may vary with floor conditions and temperature. For enhanced grip on wet or slippery surfaces, consider alternatives with high-traction polyurethane compounds designed specifically for those conditions.
