Frequently Asked Questions
Q: What are the specifications for the HJ 130 spring used in manual pallet jacks?
A: The HJ 130 is a compression or return spring used in manual pallet jack pump and linkage mechanisms. Spring force (measured in pounds-force or Newtons), free length, compressed length, and wire diameter are precisely engineered for specific pump models. Contact us with your equipment model and serial number to confirm the exact spring specifications and force rating needed for your application.
Q: Which manual pallet jack equipment models use the HJ 130 spring?
A: The HJ 130 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT that incorporate similar pump return or linkage spring designs. Compatibility is specific to equipment model and vintage. Verify your equipment documentation and compare spring specifications before ordering to ensure correct fitment.
Q: What material is the HJ 130 spring made from and what is its typical service life?
A: The HJ 130 is manufactured from high-carbon steel or stainless steel with precise heat treatment to provide consistent spring force over thousands of compression cycles. In normal operating conditions with regular maintenance, this spring typically lasts 3-5 years. Lifespan varies based on load cycles, corrosion exposure, and storage conditions. Saline or humid environments may reduce spring life due to corrosion.
Q: What are the signs that the HJ 130 spring needs replacement?
A: Replace the HJ 130 spring if the pump handle does not return smoothly to the fully raised position, if lifting action becomes sluggish or incomplete, if the pump feels mushy or lacks firmness during operation, if you observe visible rust, pitting, or corrosion on the spring surface, or if the spring has developed permanent set and will not extend to its original length. Any of these conditions indicates spring fatigue or corrosion requiring replacement.
Q: What happens if I use an incorrect spring force rating in my pallet jack?
A: Using an incorrect spring force can significantly impact pallet jack performance. A spring that is too weak will not return the pump handle smoothly or support the load weight properly, resulting in slow lifting or handle resistance. A spring that is too strong creates excessive resistance during pumping and accelerates wear on the pump mechanism. Always match the exact spring specification and force rating to your equipment OEM requirements.
