In the heavy machinery ecosystem, the Mag 170vp Travel Motor stands as a pinnacle of hydraulic engineering. Specifically designed for excavators in the 20 to 30-ton class, this dual-displacement axial piston motor combined with a high-torque planetary gearbox provides the necessary tractive effort for rugged terrains. As a leading China Mag 170vp manufacturer, Weitai Hydraulic has reverse-engineered and optimized these units to meet and exceed original equipment manufacturer (OEM) standards, ensuring seamless compatibility with brands like Komatsu, Kobelco, and Doosan.
The "VP" designation refers to the Variable Displacement capability, allowing operators to toggle between high-speed/low-torque for relocation and low-speed/high-torque for heavy digging or uphill climbs. This transition is managed by an integrated swash plate mechanism, which responds to pilot pressure or electrical signals, optimizing fuel efficiency and mechanical longevity.
Utilizing high-strength alloy steel and precision-honed piston bores, our Mag 170vp motors achieve volumetric efficiency rates exceeding 95%, reducing heat generation and energy loss.
Safety is paramount. Our motors include an automatic spring-applied, hydraulic-released (SAHR) parking brake, ensuring the machine remains stationary on steep inclines.
The multi-stage planetary gear system is heat-treated for maximum surface hardness (HRC 58-62), providing exceptional shock resistance during sudden load changes.
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. We can design and customize according to drawings to meet the diverse needs of customers.
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. This resulted in the demand and production of over 40,000 Weitai travel motors in 2019. Weitai travel motors are now even included in the production line for excavator manufacturers such as SANY, XCMG and SDLG.
As the Shandong Hydraulic Association’s (SDHA) Secretary Company, Weitai is proud to represent China and share our high quality hydraulic products with the world.
By situating our hub in Qingdao, we leverage a world-class supply chain ranging from raw casting foundries to precision CNC machining centers, reducing lead times by up to 30% compared to European counterparts.
Our engineering team utilizes AI-driven simulation software to model fluid dynamics within the Mag 170vp casing, allowing for customized flow rates and pressure settings tailored to specific regional application scenarios.
Producing over 40,000 units annually allows us to amortize fixed costs, providing a competitive price-to-performance ratio that is unbeatable in the global aftermarket and OEM sectors.
The hydraulic industry is moving toward "Electrification" and "Intelligence." Future iterations of the Mag 170vp series will incorporate IoT sensors to monitor oil temperature, pressure spikes, and vibration in real-time. This Predictive Maintenance capability will significantly reduce downtime for global mining and construction fleets. As a forward-thinking travel motor supplier, Weitai is already prototyping sensors that communicate directly with excavator ECU systems via CAN-bus protocols.
