Heavy Duty Integrated Gearbox Traveling Device Polyurethane Rim Wheel Set
Shenchuan Traveling Device is a fully integrated undercarriage assembly engineered for heavy-duty industrial rail haulage and underground material transport. Combining a precision-machined wheel set, an integrated reduction gearbox, a universal joint drive shaft, and a high-performance polyurethane rim, this unit delivers exceptional traction, shock absorption, and load-bearing capacity. The distinctive orange polyurethane rim significantly reduces vibration, noise, and wheel wear while protecting the track from impact damage. Designed for continuous operation in abrasive, humid, and demanding environments, this complete assembly ensures reliable power transmission, stable handling, and extended service life for 12-ton and similar class electric locomotives and industrial transfer vehicles.

Manufacturing & Engineering Process
The traveling device is manufactured through a series of precision processes: high-strength alloy steel billets are forged and normalized to relieve internal stresses; wheel cores are CNC-machined to exact rolling circle diameters and flange profiles; the polyurethane rim is cast and vulcanized onto the wheel core to ensure a permanent, high-strength bond that absorbs shock and dampens vibration; gear components are cut on precision hobbing machines, then carburized and hardened for high surface hardness and core toughness; the integrated gearbox housing is precision-machined for perfect bearing bore alignment; the universal joint drive shaft is balanced to eliminate vibration at operating speeds; all components are assembled with heavy-duty bearings, seals, and lubricated for long-term operation; the completed assembly undergoes rigorous run-in testing to verify smooth rotation, proper gear meshing, and leak-free sealing.
