Closed Loop Hydraulic System For Tracked Combine Harvester

Closed Loop Hydraulic System For Tracked Combine Harvester

Optimized Closed Loop Drive for Tracked Harvesters: Specifically engineered for tracked combine harvesters, the closed loop hydraulic system delivers smooth traction control, precise speed regulation, and efficient power transfer under varying field conditions.
High Torque and Stable Performance: The system provides strong torque output at low speeds, ensuring reliable driving force for tracked machines operating in soft soil, uneven terrain, and heavy crop loads.
Integrated Pump and Motor Matching: Precisely matched axial piston pumps and motors reduce energy loss, improve system response, and enhance overall efficiency and durability of the hydraulic drive system.
Designed for Harsh Agricultural Environments: High-quality materials, advanced sealing, and precision machining enable stable operation under dust, vibration, high temperature, and continuous working cycles typical of harvesting seasons.
Flexible Configuration for OEM Applications: Multiple displacement options, control methods, and mounting interfaces are available, allowing easy integration into different tracked combine harvester platforms and OEM hydraulic architectures.

Packing & Delivery

To ensure the safe delivery of variable piston pump and hydraulic motor, we utilize multiple layers of protective packaging. The pump is first sealed in a durable plastic bag to prevent moisture and contamination. Next, it is securely fixed within a reinforced plywood case to prevent movement and damage during transportation, given the heavy weight of the product. Finally, the plywood case, built to standard export specifications, provides sturdy protection suitable for international shipping.
