CR 310147

Frequently Asked Questions

Q: What are the key features of the CR 310147?
A: The CR 310147 is a Crown load wheel assembly with a heavy-duty polyurethane tread, internal steel core, and greaseable bearings. This combination provides superior flat-spotting resistance and extended service life in demanding heavy-load, long-run electric lift truck operations.

Q: Can the CR 310147 bearings be re-greased in the field?
A: Yes. The CR 310147 features greaseable bearings that can be serviced in the field. This allows technicians to extend bearing life through periodic lubrication maintenance, reducing unexpected downtime from bearing wear.

Q: What advantages does the steel core provide?
A: The internal steel core provides superior structural rigidity and resists deformation under extreme loading. Steel cores outperform aluminum or cast iron alternatives, making the CR 310147 ideal for maximum-load capacity operations over long distances without flat spotting.

Q: What type of lubrication should be used for the CR 310147 bearings?
A: Use a lithium-based grease suitable for load wheel bearing maintenance. Consult Crown Equipment documentation for specific grease specifications and lubrication intervals to maintain optimal bearing performance and extend wheel service life.

Q: Is the CR 310147 compatible with all Crown electric lift trucks?
A: The CR 310147 is validated for Crown electric lift trucks. Verify your equipment model, bearing bore size, and core design specifications match the CR 310147. Contact Crown Equipment or a certified parts distributor with your truck model and serial number for specific fitment confirmation.
