HL 145

Frequently Asked Questions

Q: What is the HL 145 Spring used for?
A: The HL 145 Spring is a compression spring in the Hu-Lift HP25L hydraulic pump assembly. It maintains pressure on the pump piston and ensures consistent hydraulic flow during lift and lower operations.

Q: What equipment does the HL 145 Spring fit?
A: The HL 145 Spring is designed for Hu-Lift HP25L manual pallet jacks. Confirm your pallet jack model and serial range match before ordering.

Q: What happens if the HL 145 Spring becomes damaged or weak?
A: A weakened or broken HL 145 Spring reduces pump pressure, causing slow lift cycles, incomplete load raising, and excessive handle effort. The pallet jack may not hold loads at raised height without continuous pump engagement.

Q: Can the HL 145 Spring be repaired or must it be replaced?
A: The HL 145 Spring cannot be repaired and must be replaced as a complete unit. Spring deformation is permanent and cannot be restored through cleaning or adjustment.

Q: What is the material composition of the HL 145 Spring?
A: The HL 145 is a hardened steel compression spring designed to withstand repeated cycling and high pressure loads in hydraulic pump applications. The exact spring rate and dimensions are optimized for HP25L specifications.

Q: How often should the HL 145 Spring be replaced?
A: The HL 145 Spring typically lasts 3 to 6 years under standard use. Replace it when lift performance degrades, if you notice permanent set in the spring, or if visually corroded. Usage intensity and load weight affect service life.
