Frequently Asked Questions
Q: What does the HD designation mean for the CL 1806279-HD?
A: HD indicates Heavy Duty. The CL 1806279-HD is engineered specifically for high-cycle warehouse operations, rated load capacity up to 5500 lbs, and optimized for extended service in demanding environments. The red polyurethane tread, aluminum hub, and precision sealed bearings work together to maximize durability under continuous use.
Q: What equipment is the CL 1806279-HD compatible with?
A: The CL 1806279-HD is designed for Clark manual pallet jacks, specifically listed for compatibility with Clark CJ55 models. The 7-inch diameter assembly, 2-inch hub width, and 20 mm bore match Clark specifications. Always verify your equipment serial range and model against Clark compatibility documentation before ordering.
Q: What makes the red polyurethane tread different from standard polyurethane?
A: The red polyurethane formulation is optimized for high-cycle duty, offering superior wear resistance and extended tread life. The 90 Shore A nominal hardness specification balances grip and durability, providing consistent floor contact across a range of floor types while resisting accelerated wear common in high-traffic warehouse applications.
Q: How long should the CL 1806279-HD last in heavy warehouse duty?
A: Heavy-duty red polyurethane wheels typically perform for 18 to 24 months in high-cycle operations, with potential for extended service in moderate-use environments. The precision sealed bearings reduce bearing-related downtime. Inspect tread monthly for wear patterns and replace when tread thickness drops below 0.25 inches or if the wheel loses roundness.
Q: What maintenance is required for the CL 1806279-HD?
A: Clean the wheel assembly monthly with water and a soft brush to remove debris. The sealed bearing design requires minimal maintenance, but check monthly for bearing play and listen for grinding noises. Inspect the anodized aluminum hub for impact damage or corrosion. Wipe the red polyurethane tread to maintain grip. Do not use aggressive solvents on the tread surface.
Q: Is the CL 1806279-HD suitable for wet or cold storage applications?
A: The CL 1806279-HD is optimized for standard warehouse conditions and moderate moisture exposure. It is not designed for extended wet floor or cold storage duty. For operations with heavy water exposure or cold storage requirements, contact us to verify alternative tread compounds such as EZ High Traction formulations engineered for those conditions.
