Frequently Asked Questions
Q: What are the key dimensions of the KA 78730186 load wheel?
A: These dimensions are designed for specific Komatsu equipment that accept this standard bore configuration.
Q: What materials is the KA 78730186 wheel made from?
A: The wheel features a polyurethane tread with a nominal hardness of 93 Shore A bonded to a machined steel core. This construction provides strength and durability for material handling applications.
Q: Is the KA 78730186 a complete wheel assembly?
A: The KA 78730186 is the wheel body only. It does not include bearings, hub, or axle components. If you need a fully assembled load wheel with all mounting hardware, confirm the complete assembly designation with your supplier.
Q: What Komatsu models use the KA 78730186 load wheel?
A: This wheel is designed for Komatsu electric lift trucks. To verify compatibility with your specific model, consult your Komatsu equipment documentation or parts manual.
Q: What is the expected lifespan of the KA 78730186 polyurethane tread?
A: Tread lifespan depends on load capacity, floor conditions, and usage frequency. The 93 Shore A polyurethane provides moderate wear resistance suitable for general indoor material handling. Rough concrete surfaces and heavy continuous use will accelerate wear. Regular inspection helps track condition and plan replacement timing.
Q: Can I use the KA 78730186 on slippery or wet surfaces?
A: The standard 93 Shore A polyurethane tread is rated for dry indoor use. For wet floors, cold storage, or slippery environments, consult with your Komatsu dealer about higher-durometer or specialized tread compounds designed for those conditions.
