CR 120249

Frequently Asked Questions

Q: What is the CR 120249 compression spring used for on Crown Wave pallet jacks?
A: This compression spring is part of the lift mechanism and provides consistent force during mast extension and retraction. It works in conjunction with the hydraulic system to control lift speed and stability.

Q: What are the spring specifications for the CR 120249?
A: Spring specifications typically include load rate (pounds per inch of compression), free length, compressed length, and wire diameter. Verify exact dimensions from the product specification sheet to ensure compatibility with your Wave model.

Q: What causes compression springs to fail on pallet jacks?
A: Springs fail from metal fatigue after millions of compression cycles, corrosion from moisture and salt exposure, or overload conditions. A failed spring reduces lift control and increases load sway during raising and lowering.

Q: What is the material composition of the CR 120249?
A: Compression springs for material handling equipment are typically formed from high-carbon alloy steel or stainless steel. Stainless options are preferred for cold storage and wet environments to resist corrosion.

Q: How does the CR 120249 differ from the CR 120250?
A: Both are compression springs for Crown Wave models. They differ in load rate, length, or application position. Confirm your exact model and failure symptoms to order the correct SKU. Do not interchange them.

Q: What is the typical service life for this compression spring?
A: Under normal operating conditions, compression springs typically last 5 to 10 years or longer, depending on usage intensity and environment. Springs in cold storage or wet conditions may corrode faster and require earlier replacement.
