View SpecificationsModern heavy machinery, especially crawler excavators in the Hitachi EX and ZX ranges, operates under punishing cyclical pressures. These environments demand hydrostatic propulsion systems that deliver consistent torque without thermal runaway. As an established OEM Hitachi Travel Motor Supplier, Weitai Hydraulic leverages decades of specialized metallurgical and volumetric research to deliver final drives that withstand these pressures.
A travel motor (or track drive) works by converting hydraulic flow from the main pump into mechanical torque, which is then multiplied by a multi-stage planetary gearbox. Achieving efficient performance requires strict control over machining clearances, high-strength rotary components, and premium-grade seals. Our engineering philosophy targets reducing internal leakage, a primary cause of travel speed drift and track deviation on older machinery.
Whether operating in mining sectors, civil infrastructure, or forestry, Weitai’s aftermarket and custom-built travel assemblies deliver reliable service life. By sourcing from a high-quality manufacturer, heavy equipment distributors and fleet operators ensure minimum downtime and seamless compatibility.
Shandong’s premier hydraulic engineering export platform, driving industrial excellence worldwide.
Weitai Hydraulic is one of China’s leading hydraulic suppliers, recognized as one of the earliest hydraulic enterprises specializing in export business for decades. We are committed to providing excellent hydraulic products and services to both businesses and final users worldwide.
At the beginning, we operated as a dedicated OEM factory, gradually developing into a comprehensive company integrating production, trade, and investment. Hydraulic motors are one of our main products. In addition to our own hydraulic factories, we are a shareholder of a high-quality hydraulic motor manufacturer. Our factories are all ISO certified and our material suppliers have obtained CE, RoHS, CSA, and UL certificates. We design and customize according to engineering drawings to meet diverse customer needs.
Our motor products include but are not limited to travel motors, swing motors, and wheel motors. Featuring advanced design structures, our motors provide high volumetric efficiency, strength, and stability that exceed competitor benchmarks. This engineering superiority resulted in the demand and production of over 40,000 Weitai travel motors in 2019. Weitai travel motors are now included in the production lines for major excavator manufacturers such as SANY, XCMG, and SDLG.
As the Shandong Hydraulic Association’s (SDHA) Secretary Company and the comprehensive export platform of the provincial hydraulic organization, Weitai represents China's hydraulic engineering standards. Weitai Hydraulic was elected as the 2018 Annual Outstanding Enterprise at the Annual Conference and Intelligent Manufacturing Forum of the Shandong Equipment Manufacturing Association, and we continue to build on this success.
Inside Weitai's R&D focus: materials science, mechanical stress optimization, and low-wear dynamic components.
Using ductile iron (QT500-7 and QT600-3) to resist stress fractures and control housing flexing under spike pressures of up to 450 bar.
Equipped with dual-floating mechanical face seals to prevent water, mud, and silica intrusion, keeping lubrication oil clean.
Automatic high/low speed pilot valve controls variable swash plate angles, optimizing torque output dynamically based on drag.

Our manufacturing complex in Qingdao, Shandong, integrates key production stages under one roof to maintain stable supply chains. By sourcing materials locally and using high-precision casting hubs in Shandong, we minimize supply bottlenecks and deliver final drives reliably.
Each travel motor undergoes a series of quality gates before shipping. Precision machining of critical parts like pistons, cylinders, and valve plates is completed on CNC centers imported from Germany and Japan. Afterward, assemblies undergo cleanroom operations to prevent hydraulic oil contamination.
Our modern testing facility uses customized digital dynamometers to monitor real-time flow rate, startup pressure, efficiency curves, and planetary torque distribution. This rigorous testing approach supports Weitai's quality guarantee for heavy-duty earthmoving equipment.
Weitai regularly presents our high-performance hydraulic systems at major international trade exhibitions, including Bauma and PTC Asia.
