Frequently Asked Questions
Q: What is the 079904-00A chain assembly used for?
A: The 079904-00A is a chain assembly for manual pallet jacks. This assembly connects the handle lever to the hydraulic pump and lifting mechanism. It transfers mechanical force from the operator into vertical load movement.
Q: What manual pallet jack models use the 079904-00A?
A: The 079904-00A is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other major brands. The 00A suffix indicates a specific variant. Verify your exact truck model and serial range before ordering to ensure fitment.
Q: What is the difference between the 079904-00A and 079904-A?
A: The 079904-00A and 079904-A are chain assembly variants. The 00A designation likely indicates a different chain pitch, length, or link count than the A version. Do not substitute one for the other without confirming exact specifications match your equipment.
Q: What materials are used in this chain assembly?
A: The chain is typically forged steel for strength and durability. Links are hardened to resist wear and bending under load. The assembly may include pins, bushings, and fasteners rated for industrial use. The complete assembly is designed to withstand repeated lifting cycles.
Q: When should this chain assembly be replaced?
A: Replace the chain when you notice excessive slack, binding, or resistance in the lifting lever. Visible rust, corrosion, broken links, or cracked pins indicate failure. If the pump no longer engages or disengages smoothly, the chain assembly is likely worn out.
Q: How long does a manual pallet jack chain typically last?
A: Chain assemblies in typical warehouse use last 3 to 7 years depending on load frequency and maintenance. Harsh environments, overloading, or dry operation accelerate wear. Proper lubrication and regular inspections extend service life.
