The excavator travel reducer gearbox (Travel Reducer) is the core transmission component that converts hydraulic power from the travel motor into driving torque.
Ribiao was founded in 1995, with 30 years of dedicated expertise in manufacturing travel reducer assemblies, covering mainstream brands such as Caterpillar, Komatsu, Hitachi, Kobelco, Volvo, Doosan, and Hyundai for 20T~90T class machines. Every unit undergoes dual testing—no-load operation and air tightness—before leaving the factory, achieving a pass rate of over 99%.
