In the global landscape of hydraulic propulsion, Tong Myung Travel Motors (now integrated under brands like Doosan/Mottrol) have long set the benchmark for excavators and tracked machinery. As a premier China-based manufacturer, Weitai Hydraulic has pioneered the "Information Gain" approach in high-performance hydraulics—not merely replicating OEM specs, but enhancing the durability, volumetric efficiency, and serviceability of travel drives for the modern era.
Today's procurement directors aren't just looking for a "factory"; they are seeking Supply Chain Resilience. This report explores how Chinese engineering is bridging the gap between legacy Tong Myung designs and the future of Industry 4.0 hydraulic solutions.
Units Produced Annually (2019 Base)
OEM Suppliers for SANY, XCMG, SDLG
Global Compatibility with TM07/TM10/TM22 Series
Integration of IoT sensors into the travel motor housing to monitor pressure, temperature, and vibration in real-time, preventing catastrophic failures in mining and heavy construction applications.
Adoption of specialized heat-treated alloys for planetary gears and friction plates, extending the service life by 35% compared to standard aftermarket Tong Myung alternatives.
Development of L and K frame variable motors (LC20 series) that optimize torque-to-speed ratios for faster machine relocation without compromising climbing power.
Weitai Hydraulic operates at the nexus of the Shandong Hydraulic Association (SDHA), leveraging a cluster-based supply chain that ensures zero-delay production. Our "Smart Factory" initiatives include:
Optimized final drives for mini-excavators (1.5t to 9t) and heavy crawlers, ensuring seamless compatibility with Nachi, Kayaba, and Tong Myung footprints.
Ruggedized motors for skid steer loaders and harvesters operating in high-debris and high-moisture environments.
Heavy-duty travel drives designed for extreme incline capabilities and high-pressure hydraulic circuits.
Weitai Hydraulic is one of China’s leading hydraulic suppliers, the earliest hydraulic enterprises which 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 first beginning, we are OEM factory, and have gradually developed 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 all obtained CE, RoHS, CSA and UL certificates.
The Motor products include but are not limited to travel motors, swing motors and wheel-motors. Our motors have an advanced design structure and provide high volume efficiency, high strength and good stability which far superior than our competitors’ motors. In 2019, over 40,000 Weitai travel motors were produced, and are now included in the production line for excavator manufacturers such as SANY, XCMG and SDLG.
Secretary Company: Shandong Hydraulic Association (SDHA)
Award: 2018 Annual Outstanding Enterprise in Intelligent Manufacturing.
We provide 24-hour rapid response for technical consultations, ensuring that your engineering team has the CAD drawings and performance curves needed for machine integration.
Full compliance with EU Machinery Directive and North American safety standards. We handle the complexity of international logistics and customs documentation.
Industry-leading 12 to 24-month warranty programs that mirror or exceed original Tong Myung factory terms.
A: Yes. Our motors are engineered to match the exact mounting dimensions, hydraulic port locations, and performance characteristics of Tong Myung TM series motors. This ensures a "plug-and-play" experience for field replacements.
A: We use high-grade ductile iron for housings and hardened steel for all internal rotating parts. Every unit is tested on a dynamic test rig to simulate real-world excavator operations before dispatch.
A: Absolutely. Our technical team can customize displacement, brake torque, and gear ratios based on your specific undercarriage requirements and machine weight.
