Frequently Asked Questions
Q: What equipment does the CT 971757-XL load wheel fit?
A: The CT 971757-XL is designed for Caterpillar electric pallet jacks and electric lift trucks. fits continuous-duty electric equipment. Always verify your equipment matches before ordering, as mismatch will prevent proper fitment.
Q: What does the 97A durometer rating mean?
A: The CT 971757-XL features a 97A Shore durometer polyurethane compound, indicating a high-hardness formulation with excellent wear resistance and load-carrying capacity. This grade is specifically engineered for continuous-duty electric lift truck environments where consistent performance is required over extended operational cycles.
Q: Why does the core material matter on this wheel?
A: The CT 971757-XL uses a machined steel core, which provides structural rigidity and precise load distribution. The machined finish ensures accurate axle bore tolerancing and concentricity, critical for balanced wheel rotation and axle longevity under continuous electric truck duty cycles.
Q: What is the expected service life of the CT 971757-XL?
A: Lifespan depends on load weight, floor conditions, and duty cycle. In typical continuous-duty electric service, expect active use before tread performance degrades, though the steel core remains serviceable. Monitor wheel grip on wet or contaminated floors as an indicator of wear.
Q: Why is tread width important for compatibility?
A: The CT 971757-XL must match your equipment fork arms or wheel carriage slots. A wheel too narrow will wobble; one too wide will not fit in the frame. Always confirm your current before ordering replacement wheels.
Q: How should I maintain and inspect this wheel?
A: Inspect the CT 971757-XL monthly for glazing, flat spots, or debris contamination. Clean regularly with mild detergent and water; avoid harsh solvents that degrade polyurethane. Monitor for uneven wear patterns indicating misalignment or bearing issues. The steel core is maintenance-free but the tread will gradually harden and lose grip over time.
