PR 11073-21

Frequently Asked Questions

Q: What is the PR 11073-21 roll pin designed for?
A: The PR 11073-21 is a spring pin fastener for electric lift truck assemblies, including electric pallet jacks and walkie lifts. It secures pivot connections and chassis components subject to dynamic shear forces and repetitive movement.

Q: What material is the PR 11073-21 manufactured from?
A: The PR 11073-21 is manufactured from high-carbon spring steel suitable for dynamic shear applications. This material provides high shear strength and elastic recovery needed for maintaining secure mechanical joints through extended equipment service life.

Q: Which electric lift truck models accept the PR 11073-21?
A: The PR 11073-21 is an OEM specification fastener for Prime Mover electric pallet jacks and walkie lifts. Confirm your specific equipment model and assembly location match before ordering to ensure compatibility.

Q: What performance benefit does high-carbon spring steel provide in this application?
A: High-carbon spring steel in the PR 11073-21 delivers consistent shear strength under the cyclic loading of electric lift truck operation. The material resists permanent deformation and maintains tension to prevent joint loosening during thousands of raise and lower cycles.

Q: What signs indicate a PR 11073-21 roll pin needs replacement?
A: Replace the pin if you observe bending, visible wear, separation of assembly components, unusual noise from pivots, or loose steering and control response. Do not delay replacement as a failed pin can cause equipment instability and safety hazards.
