SPRING
Frequently Asked Questions
Q: What electric lift truck models does the SP-424 spring fit?
A: The SP-424 is designed for Crown, Toyota, Raymond, Yale, and Linde electric lift trucks. Verify your specific model year and series against the technical documentation before ordering to confirm compatibility.
Q: What are the load rating and spring specifications for the SP-424?
A: The SP-424 has defined load ratings and spring constants specific to electric lift truck mast heights and capacities. Confirm the load rating, spring rate, and dimensional specifications match your equipment to ensure safe and correct operation.
Q: What material is the SP-424 spring constructed from?
A: The SP-424 is manufactured from high-carbon alloy steel with protective corrosion-resistant coating. This composition provides durability and consistent performance in electric truck operations across standard and cold storage warehouses.
Q: What failure symptoms indicate the SP-424 needs replacement?
A: Replace the SP-424 if you observe mast sagging when unloaded, uneven load platform positioning, reduced lift capacity, visible rust, or audible spring noise during operation. These signs indicate loss of spring force and potential safety risks.
Q: What is the expected service life of the SP-424?
A: The SP-424 typically lasts 3 to 5 years under normal electric truck operating conditions. High-cycle pick-and-place operations or continuous cold storage use may reduce lifespan. Inspect springs annually for performance degradation.
Q: Does the SP-424 require maintenance or lubrication?
A: Inspect the SP-424 quarterly for corrosion, cracks, or sagging. Keep it clean and dry. Do not apply lubricants. Replace the spring if compression force decreases noticeably or visible damage appears.
