Frequently Asked Questions
Q: What is the PU AA-70 roll pin used for?
A: The PU AA-70 is a precision roll pin engineered to retain the control lever and rod assembly in Pallet Mule manual pallet jack handle systems. It prevents accidental dislodgement of the lever mechanism during normal jack operation and repositioning.
Q: What are the specifications and dimensions of the PU AA-70?
A: The PU AA-70 is a 0.250 inch diameter, 1.25 inch nominal length roll pin manufactured from high-carbon steel conforming to ASTM A108 specifications. It is heat-treated to Rockwell C45 hardness, ensuring secure retention without deformation under typical control lever operating loads.
Q: Which Pallet Mule models are compatible with the PU AA-70?
A: The PU AA-70 is the factory-spec direct replacement for Pallet Mule AA5000 and AA5500 models. Cross-reference alternatives include PUAA-70, AA-70, and PTAA-70.
Q: Why is high-carbon steel with Rockwell C45 heat treatment used for this roll pin?
A: High-carbon steel (ASTM A108) provides strength and wear resistance, while Rockwell C45 heat treatment ensures the pin maintains hardness and structural integrity under repetitive stress from control lever actuation. This combination prevents shearing and premature wear.
Q: Are there alternative part numbers for the PU AA-70?
A: Yes. Alternative part numbers include PUAA-70, AA-70, and PTAA-70. All reference the same roll pin specification and dimensions. Verify the exact part number against your equipment documentation to ensure correct fitment.
Q: When should the PU AA-70 roll pin be replaced?
A: Replacement becomes necessary if the pin becomes bent, fractured, or exhibits visible wear after heavy use or impact damage. Under normal warehouse and material handling use, this pin typically provides extended service life comparable to the handle assembly itself.
