Frequently Asked Questions
Q: What is the purpose of a spring-loaded caster on electric lift trucks?
A: Spring-loaded casters provide automatic load adjustment and suspension on electric pallet jacks and lift trucks. The spring mechanism compresses under load and returns to neutral when weight is removed, which helps absorb impacts and improves stability on uneven warehouse floors and rough surfaces.
Q: Which electric lift truck models use part number A000021149?
A: Part number A000021149 is compatible with various electric pallet jack and lift truck models from manufacturers including Crown, Toyota, Raymond, Yale, and Hyster. Verify your equipment model and serial range before ordering to confirm fitment.
Q: What maintenance do spring-loaded casters require?
A: Spring-loaded casters should be inspected regularly for corrosion, debris accumulation, and spring tension loss. Clean the caster housing and bearing surfaces periodically. If the spring no longer returns to its original height or shows visible damage, the caster should be replaced to maintain load stability.
Q: How long does a spring-loaded caster typically last in industrial use?
A: Lifespan depends on load cycles, warehouse conditions, and maintenance frequency. Spring-loaded casters in continuous use typically last 2 to 4 years. Failure symptoms include reduced spring response, wobbling, or noise during operation. Replace immediately if the caster cannot support full load capacity.
