Frequently Asked Questions
Q: What are the key specifications of the CT 1201778-A load wheel assembly?
A: The CT 1201778-A is a complete load wheel assembly with high-impact polyurethane tread, precision-machined steel core, sealed ball bearing, and Shore A 92 hardness rating. This design is engineered for Caterpillar electric lift truck applications requiring durable, precision-fit wheel assemblies.
Q: What does a Shore A 92 hardness rating indicate?
A: Shore A 92 indicates a moderately firm polyurethane compound that balances load capacity and floor grip. This hardness level resists permanent deformation under heavy sustained loads while providing adequate traction and floor protection. It is suitable for intensive warehouse and dock duty cycles.
Q: What cross-reference part numbers are compatible with CT 1201778-A?
A: The CT 1201778-A cross-references to Caterpillar part number 1201778 and SK02191115JE. These alternate part numbers identify direct replacements. Always verify your equipment documentation lists the correct cross-reference before ordering.
Q: Is this wheel assembly compatible with non-Caterpillar lift trucks?
A: The CT 1201778-A is engineered for Caterpillar electric lift trucks. While the dimensions may fit other brands, always confirm your equipment specification matches before ordering. Using mismatched wheels can cause alignment issues and safety hazards.
Q: Why is the steel core preferred over nylon cores?
A: The precision-machined steel core provides superior rigidity and load distribution compared to nylon alternatives. Steel cores resist deflection under sustained heavy loads and offer better radial strength, making them ideal for intensive duty cycles on commercial electric lift trucks.
Q: What maintenance does the sealed bearing require?
A: The sealed ball bearing requires no maintenance or lubrication during normal operation. The seal excludes contaminants and retains internal grease permanently. Replace the entire assembly when bearing noise or excessive lateral play indicates wear.
Q: What is the weight and load capacity of this wheel assembly?
A: The CT 1201778-A is a load wheel (non-drive) component designed to support palletized loads on Caterpillar electric lift trucks. Refer to your truck's technical manual for total load capacity and wheel assembly weight specifications specific to your equipment model.
Q: Can this wheel assembly be used on manual pallet jacks?
A: The CT 1201778-A is designed for Caterpillar electric lift truck applications. Manual pallet jacks typically use different wheel bore sizes and load specifications. Consult your manual pallet jack documentation before attempting to install this assembly.
