Frequently Asked Questions
Q: What pallet jack model does the LF 221227 overload spring fit?
A: The LF 221227 is an overload spring designed specifically for Lift-Rite model PL30277 manual pallet jacks. Confirm your pallet jack model and serial range match PL30277 before ordering this component.
Q: What is the function of the overload spring in the PL30277?
A: The overload spring works as part of the pressure relief valve assembly. It maintains consistent spring tension on the valve mechanism to regulate hydraulic pressure and prevent pump damage when the pallet jack encounters loads at or beyond its rated capacity.
Q: How can I tell if the LF 221227 spring needs replacement?
A: Replace the overload spring if pressure relief activates at lower loads than specifications call for, if the pump continues lifting beyond the rated load capacity, or if the spring shows visible corrosion, rust, or permanent deformation. A weak or fatigued spring will not maintain proper valve tension.
Q: What material is the LF 221227 overload spring made from?
A: The LF 221227 is manufactured from spring steel designed to withstand repeated compression cycles without permanent set or fatigue failure. The steel specification ensures the spring maintains consistent load-bearing characteristics throughout the service life of the pallet jack.
