Forklift Assembly

SPIROL analyzed the application and assembly process and determined that standard duty SPIROL® Coiled Spring Pins would significantly reduce the insertion force. SPIROL also recommended the use of their CXA and CXD Pin-Driving Chucks and a pneumatic hammer rather than installing the pins using a traditional hammering method. In addition to alleviating the repetitive strain issue, the fact that Coiled Pins do not have a gap would eliminate the issues with the pins interlocking. Coiled Pins would also allow the manufacturer to widen their hole tolerances which would result in a 3X reduction in insertion forces as well as a reduction in the assembly process time.

Through comprehensive performance testing, the manufacturer validated the use of the Coiled Spring Pins over the previously used Slotted Spring Pins as well as the installation process with pneumatic hammers and SPIROL® Pin-Driving Chucks.

By partnering with SPIROL to find a solution to improve their assembly process and prevent injuries of their employees, the forklift manufacturer benefited from using a superior fastener, a faster and safer assembly process, as well as an overall cost savings. Using pneumatic force with SPIROL’s Pin-Driving Chucks and wider hole tolerances rather than relying solely on the force of the operator’s arm with the tighter hole tolerances eliminated 1.8 million hammer blows per year and the costs associated with medical fees and lost time!
