120564301

Frequently Asked Questions

Q: What is the 120564301 and what applications does it serve?
A: The 120564301 is an industrial-grade polyurethane wheel designed for electric pallet jacks and electric lift trucks. It combines a polyurethane elastic tread with a cast iron QT450 wheel center and press-on steel ring base. This wheel is engineered for minimal compression deformation, optimal rolling resistance, and reliable operation in freezer environments down to -40°C. Compatible with electric lift trucks from major manufacturers including Crown, Toyota, Raymond, Yale, and Hyster.

Q: What materials are used in the 120564301 and why?
A: The 120564301 uses industrial-grade polyurethane for the tread, providing a non-marking, elastic compound that resists wear and deformation under load. The wheel center is cast iron (QT450 specification per GB/T-20 standard), offering superior strength and durability. The press-on steel ring base provides axle security and vibration damping. This three-material construction balances load capacity, low rolling resistance, and operational reliability across warehouse and cold storage environments.

Q: How does the 120564301 perform in freezer and cold storage environments?
A: The 120564301 is specifically rated for operation in freezer environments to -40°C. The industrial-grade polyurethane tread maintains elasticity and traction at sub-zero temperatures without becoming brittle or losing grip. The cast iron center resists temperature shock and thermal cycling cracking. This wheel is engineered for sustained operation in cold chain applications where standard polyurethane wheels may fail due to material brittleness.

Q: What is the typical service life of the 120564301?
A: Wheel lifespan depends on load intensity, duty cycle, and operating environment. In typical warehouse conditions with standard loading, the 120564301 typically delivers 2-4 years of service. In cold storage with lighter duty cycles, lifespan may extend to 4-5 years due to reduced polyurethane oxidation at lower temperatures. High-intensity operations or abrasive flooring may reduce lifespan to 12-24 months.

Q: What compression deformation characteristics does the 120564301 offer?
A: The 120564301 is engineered for minimal compression deformation under sustained load. The industrial-grade polyurethane formula resists permanent flattening that reduces wheel diameter and increases rolling resistance. Minimal compression deformation preserves wheel height and load distribution geometry, reducing strain on the lift truck frame and extending overall equipment lifespan. This specification is particularly valuable in cold storage where repeated thermal cycling can accelerate deformation in lower-grade wheels.

Q: How should the 120564301 be maintained during storage?
A: Store the 120564301 in a cool, dry location away from direct sunlight and heat sources, which can accelerate polyurethane oxidation. Avoid prolonged storage in temperatures above 50°C. When not in use for extended periods, store wheels vertically or on racks rather than flat to prevent permanent deformation. Keep the wheel clean and free from corrosive chemicals and solvents. Inspect regularly for visible cracks or deformation before reinstalling on equipment.

Q: What is the inspection criteria for the 120564301 before use?
A: Before operation, inspect the 120564301 for visible cracks, chunks missing from the tread, or permanent deformation. Check that the tread surface is free from embedded debris or contamination. Verify the wheel rotates freely without binding or excessive wobble. Examine the press-on steel ring base for looseness or separation from the cast iron core. If any damage is visible or the wheel does not rotate smoothly, the wheel should be replaced to ensure equipment safety.
