Compression Spring
Frequently Asked Questions
Q: What is the compression rating of the CR 122421 compression spring?
A: The CR 122421 is a compression spring designed for load-bearing applications in Crown electric lift trucks. Compression rating and specifications vary by application. Refer to your equipment manual or contact us with your model number for exact load specifications.
Q: How does the CR 122421 differ from a standard spring like the CR 122399?
A: The CR 122421 is specifically engineered as a compression spring, meaning it resists force applied along its axis. It is not interchangeable with tension springs. Each spring type has a unique application within the truck platform assembly.
Q: What material is the CR 122421 made from?
A: The CR 122421 compression spring is manufactured from high-tensile spring steel with heat treatment for optimal load-bearing performance. This material provides resistance to fatigue and maintains consistent compression under repeated cycles.
Q: When should the CR 122421 compression spring be replaced?
A: Replace the CR 122421 if you observe reduced cushioning, audible noise during platform operation, permanent deformation, or loss of hydraulic control. Compression loss indicates spring fatigue and requires immediate replacement.
Q: Is the CR 122421 a direct replacement for older Crown reach truck models?
A: The CR 122421 is an OEM Crown part for specific lift truck models. Verify compatibility with your equipment serial number and model designation. Springs are not universally interchangeable across model series.
