Frequently Asked Questions
Q: What is the UL 1407 pin used for in manual pallet jacks?
A: The UL 1407 is a pivot or hinge pin that connects the scissor arms to the main frame in manual pallet jacks. It serves as the rotation axis for the lift mechanism. This pin is compatible with most standard manual pallet jacks including Crown, Toyota, Raymond, Yale, and similar equipment using scissor-lift designs.
Q: What material and diameter specifications does the UL 1407 pin have?
A: The UL 1407 pin is manufactured from hardened steel with a typical diameter ranging from 12 mm to 16 mm and length proportional to the scissor arm assembly. The hardened steel resists shear forces and bending under rated load capacities of 2500 to 5500 pounds.
Q: How long does the UL 1407 pin remain serviceable?
A: With proper maintenance and regular lubrication, the UL 1407 pin can remain serviceable for 3 to 5 years. Pins wear faster in high-cycle applications, dusty environments, or when the scissor mechanism is not regularly greased. Corrosion can also reduce pin lifespan in wet storage conditions.
Q: What are the failure symptoms of a worn UL 1407 pin?
A: A failing UL 1407 pin causes vertical play or wobbling in the scissor arms during lift cycles, grinding or clicking sounds at the pivot point, and difficulty maintaining load stability. Severe wear results in visible play between the arm and frame. Replace the pin if these symptoms occur.
Q: Can the UL 1407 pin be interchanged between different manual pallet jack models?
A: Pin interchangeability depends on matching diameter, length, and load rating. Different equipment models may use slightly different pin dimensions or hole spacing. Verify exact dimensions and the presence of grooves or retention features before ordering replacement pins for your specific equipment.
Q: What maintenance keeps the UL 1407 pin functioning properly?
A: Regular lubrication of the pivot point extends UL 1407 pin life significantly. Apply general-purpose lithium grease to the scissor mechanism every 3 to 6 months depending on usage frequency. Keep the pin and surrounding area clean of debris and rust to prevent corrosion and ensure smooth rotation.
