Market Background

Indonesia has an active market for mining and resource transportation equipment. Coal transport vehicles used in mining operations often need hydraulic drive systems capable of handling demanding load conditions and frequent operating cycles. For low-speed mining vehicles, hydraulic motor selection is not only about achieving sufficient output torque. Low-speed operation under load, output shaft load capacity, bearing structure, and wear resistance are also important considerations.

Customer and Application

The customer was based in Indonesia and selected the KMV Series hydraulic motor for a mining coal transport vehicle. The order included 75 units, with delivery completed within 10 days.

The application required stable low-speed operation under load. At the same time, the hydraulic motor needed an output shaft and bearing arrangement suitable for the radial and axial loads associated with the vehicle drive system. These requirements made mechanical load capacity an important part of the motor selection process.

Our Solution

Based on the application requirements, we supplied the KMV Series hydraulic motor for the customer's mining coal transport vehicle. The KMV Series is designed for low-speed, high-torque hydraulic drive applications and incorporates cylindrical roller bearings internally.

The bearing configuration helps increase the output shaft's ability to withstand radial and axial loads, providing structural support for applications where the motor is exposed to demanding mechanical loading. For mining transport equipment, this design consideration is particularly relevant when evaluating long-term wear and the suitability of the hydraulic motor for loaded low-speed operation.

Customer Feedback

A total of 75 KMV Series hydraulic motors were supplied for the Indonesian mining application and delivered within 10 days. The customer's main application requirement—stable low-speed operation under load—was aligned with the design characteristics of the selected KMV Series motor.

Key Technical Parameters

The KMV Series offers multiple displacement options from 315 to 1000 ml/r. The catalogue specifies a maximum continuous pressure of 21 MPa and an intermittent pressure of 25 MPa. Depending on displacement, continuous torque ranges from 920 to 2015 N·m. The series is also available in standard motor, wheel motor, and brake motor configurations, allowing selection according to equipment layout and drive requirements.

Customer Feedback and Conclusion

For mining coal transport vehicles, hydraulic motor selection should consider more than rated torque. Low-speed operation under load, output shaft load capacity, bearing configuration, and installation requirements should be evaluated together. With cylindrical roller bearings and multiple displacement options, the KMV Series provides a practical hydraulic motor solution for low-speed, high-torque mining transportation applications.
