Frequently Asked Questions
Q: What is the CR 42057-1 STOP POLY component?
A: The CR 42057-1 is a polyurethane stop or bumper component designed for Crown electric lift truck assemblies. It is used to prevent metal-to-metal contact and absorb impact in structural or operational positions within lift truck mechanisms.
Q: Where is the CR 42057-1 STOP POLY used on Crown lift trucks?
A: The CR 42057-1 serves as a protective polymer stop in lift truck mast, carriage, or load-handling assemblies where impact protection or mechanical positioning is required. Consult your Crown equipment service manual to identify the specific mounting location for your model.
Q: What material is the CR 42057-1 STOP POLY made from?
A: The CR 42057-1 is constructed from polyurethane (POLY), a durable elastomer material that resists abrasion, impact, and repeated compression cycles typical in electric lift truck service. Polyurethane stops maintain their cushioning properties in both ambient and cold storage environments.
Q: When should I replace the CR 42057-1 STOP POLY?
A: Replace the CR 42057-1 if the polyurethane becomes cracked, hardened, or permanently deformed and no longer provides cushioning or impact protection. A degraded stop allows metal components to contact each other, creating noise, vibration, and potential structural damage.
