Spiral Pin
Frequently Asked Questions
Q: What is a spiral pin and what does it do on Big Joe electric lift trucks?
A: A spiral pin is a fastener that retains components in alignment through elastic tension. On Big Joe electric lift trucks, spiral pins hold assemblies such as wheel groups, steering mechanisms, or load arms in position while allowing controlled movement and preventing hardware loosening from vibration.
Q: How is a spiral pin different from a roll pin?
A: A spiral pin has a continuous helical spiral design with tight spring tension, providing maximum holding force in tight-tolerance applications. A roll pin has an open or slotted design and relies on radial pressure from the coil. Spiral pins are typically used where precise alignment and stronger retention are critical.
Q: What material is the BJ 061200-03 spiral pin typically made from?
A: Spiral pins like the BJ 061200-03 are typically manufactured from spring steel or stainless steel to provide the necessary elastic force and corrosion resistance for long-term use in electric lift truck assemblies.
