Frequently Asked Questions
Q: Is GWK-MJP55-LW compatible with Helmar and Maxx Jack MJP55 models?
A: Yes. GWK-MJP55-LW load wheel kit is cross-compatible with both Helmar MJP55 and Maxx Jack MJP55 manual pallet jacks. Helmar and Maxx Jack used standard axle configurations for this model series. Verify your pallet jack nameplate shows MJP55 or equivalent designation before installation. If the model designation differs, contact distributor support to confirm fitment.
Q: What are the assembly dimensions and weight specifications?
A: GWK-MJP55-LW load wheel assembly measures 5 x 2.88 x 2.44 inches (width x tread thickness x overall depth). This geometry ensures compatibility with standard MJP55 frame geometry and bearing pockets. The high-strength steel axles and precision sealed bearings support the full rated load across this compact footprint. Dimensions are critical for fork width clearance; verify your pallet jack frame can accommodate 5-inch wheel width.
Q: Can I install GWK-MJP55-LW wheels quickly during a shift, or does installation require extended downtime?
A: GWK-MJP55-LW is designed for quick-change installation. Remove the roll pins from existing load wheel axles, slide the old assembly out, and insert the new GWK-MJP55-LW assembly. Re-install roll pins and verify smooth rotation. Typical installation time per wheel is 8-12 minutes. This allows emergency wheel replacement during warehouse shifts without extended pallet jack downtime. Keep a replacement kit on hand for high-utilization operations.
Q: What material is the wheel tread, and how does it perform on different floor types?
A: GWK-MJP55-LW features ultra-polyurethane 70D Shore hardness tread bonded to high-strength steel cores with a machined steel finish. This combination provides excellent grip on polished concrete, epoxy-sealed floors, and standard warehouse surfaces. The 70D durometer prevents excessive rolling resistance on smooth floors while maintaining traction during load pickup. On rough or textured surfaces, expect faster tread wear than on polished floors.
Q: How long does GWK-MJP55-LW last before replacement is necessary?
A: GWK-MJP55-LW typically provides 2-4 years of service under normal warehouse conditions (8-10 hour daily operation). Lifespan depends on floor surface roughness, pallet weight consistency, and frequency of directional changes. Inspect wheels monthly for flat spots, cracks, or tread separation. Replace when tread material chunks, lateral axle play exceeds 1/8 inch, or bearings develop noise. Running damaged wheels beyond visible failure risks loss of pallet load control.
