Decoding Volumetric Efficiency and Mechanical Longevity
The JMV 047 Track Drive Motor represents the pinnacle of compact hydraulic engineering, specifically designed for excavators ranging from 6 to 10 tons. As a primary component of the undercarriage propulsion system, the JMV 047 integrates a high-speed axial piston motor with a multi-stage planetary gearbox. This combination provides the high torque density required for climbing steep gradients and navigating challenging terrains like swampy construction sites or rocky mining fields.
Modern procurement managers aren't just looking for "parts"; they are looking for mechanical reliability and interchangeability. The JMV 047 is often a drop-in replacement for major brands like Jeil, Kayaba, and Nabtesco. Our OEM factory ensures that every unit matches the exact displacement specs—47cc/rev—with optimized valve plate designs to reduce cavitation and heat generation.
Our JMV 047 series utilizes a integrated mechanical parking brake. When hydraulic pressure drops, the brake automatically engages via heavy-duty springs, ensuring the machine remains stationary on slopes—a critical safety feature for urban construction projects. The use of 20CrMnTi alloy steel in the planetary gears, followed by precision carburizing heat treatment, extends the wear life by 35% compared to standard aftermarket alternatives.
Located in the heart of China's hydraulic hub, we control everything from raw casting to final precision grinding, reducing lead times by 40%.
Every JMV 047 undergoes a 4nd-stage load test, simulating 500 hours of continuous operation under peak pressure of 35MPa.
By optimizing manufacturing automation, Weitai delivers OEM-quality motors at a price point that facilitates higher margins for global distributors.
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 and the comprehensive export platform of provincial hydraulic organization, Weitai is proud to represent China and share our high quality hydraulic products with the world. Weitai Hydraulic has already been elected to be the 2018 Annual Outstanding Enterprise at the Annual Conference and Intelligent Manufacturing Forum of Shandong Equipment Manufacturing Association.
We are seeing an increasing demand for integrated sensors within track drive motors. The JMV 047 is being adapted to include speed and temperature sensors that feed data into the excavator's main ECU, allowing for predictive maintenance and preventing catastrophic failures in the field.
While traditional hydraulics remains dominant, Weitai is researching hybrid drive systems. Our current JMV 047 is optimized for low-viscosity fluids to improve environmental compliance without sacrificing the 320kN torque required for heavy-duty digging.
In high-torque, low-speed environments, the JMV 047 provides the necessary traction to push through dense vegetation without overheating the hydraulic circuit.
Compact design allows for use in zero-tail-swing excavators, vital for working in tight city streets where space is at a premium.
Our specialized anti-corrosion seals make these motors ideal for mini-excavators used in sea-wall maintenance and port construction.
The JMV 047 follows international standard SAE mounting patterns. We verify compatibility through flange diameter, number of bolt holes, and sprocket pilot dimensions.
Yes, all Weitai travel motors come with a 12-month comprehensive warranty covering manufacturing defects and material failures.
As an OEM factory, we can adjust the planetary reduction ratio to optimize for either speed or torque based on your specific application needs.
For standard models like JMV 047, we maintain stock. Bulk manufacturing typically takes 15-30 days, with air and sea freight options available globally.
