Frequently Asked Questions
Q: What are the exact dimensions of the 74879331 load wheel?
A: The 74879331 has a nominal outer diameter, tread width, and hub width. These dimensions must match your equipment specification and existing wheel to ensure proper fitment and operation.
Q: What material composition makes up the 74879331?
A: The 74879331 features a polyurethane tread bonded to a machined steel core. The polyurethane is Shore A 95 durometer, providing load capacity, durability, and floor grip suitable for electric lift truck warehouse and material handling applications.
Q: Which electric lift truck brands and models use the 74879331?
A: The 74879331 is a direct replacement Komatsu part number compatible with electric lift trucks from Komatsu, Toyota, Crown, Raymond, and Yale when dimensions match your existing wheel specifications. Always verify equipment model and serial range before ordering.
Q: How does Shore A 95 polyurethane perform in different warehouse environments?
A: Shore A 95 polyurethane provides good balance between load carrying capacity, floor grip, and wear resistance. It performs well in standard warehouse, production, and distribution environments. For specialty applications like cold storage or consistent wet floors, higher-traction compounds may be preferable.
Q: What is the expected lifespan and maintenance for the 74879331?
A: Typical service life is 12 to 24 months in standard duty cycle. Lifespan depends on load weights, floor conditions, and operating hours. Heavy contamination, wet floors, or high-intensity use accelerates tread wear and may require earlier replacement. Inspect wheels periodically for tread wear and damage.
Q: Are there equivalent cross-reference part numbers for the 74879331?
A: The 74879331 is a Komatsu part number. Cross-reference and equivalent parts from other suppliers may exist, but dimensions, material properties, and bond technology vary. Verify specifications match your equipment and existing wheel before substituting with alternative part numbers.
