CAT Ms Mse Axial Piston Fixed Displacement Motor for Flat Shovel

CAT Ms Mse Axial Piston Fixed Displacement Motor For Flat Shovel

Flat shovels are essential in construction, mining, and road construction, relying on stable rotational power to drive key actions such as soil scraping, material pushing, and slope leveling. The CAT Ms Mse Axial Piston Fixed Displacement Motor is engineered to be the "power executor" of these operations, converting hydraulic energy into mechanical rotation with high efficiency. As an axial piston fixed motor, it features a fixed displacement design that delivers consistent torque and speed-critical for the flat shovel's need to maintain steady pushing force, whether moving loose soil or compacted gravel.​

The cat ms motor is tailored for medium-duty flat shovels (5-10 ton operating weight), with a compact structure that fits into the limited space of the shovel's hydraulic drive system. Its precision-machined piston and cylinder block ensure minimal internal leakage, even during long hours of continuous operation. The cat mse motor, designed for heavy-duty flat shovels (10-20 ton), adds reinforced components to handle higher loads, making it ideal for mining sites where the shovel pushes large rock fragments. Both models inherit CAT's strict quality standards, undergoing 8,000 hours of durability testing to guarantee reliability.​

The cat ms motor and cat mse motor share a foundational strength: the axial piston fixed motor design, which delivers linear, low-pulse power. Unlike variable displacement motors that may cause speed fluctuations, their fixed displacement ensures the flat shovel's blade moves at a steady rate-preventing uneven scraping or material accumulation. In a 7-ton flat shovel, the cat ms motor maintains a constant rotation speed of 1500 RPM, ensuring the blade scrapes soil to a uniform thickness of 5-10cm, reducing the need for secondary leveling.​

Durability is another key advantage. The axial piston fixed motor structure in both models uses high-strength forged steel pistons and wear-resistant cylinder liners, with a surface hardness of HRC 58 to resist abrasion from hydraulic oil impurities. The cat mse motor adds a double-seal system to withstand the vibration and dust of mining sites, operating reliably in -30°C to 110°C environments. Whether it's the cat ms motor in a construction site flat shovel or the cat mse motor in a mining flat shovel, both maintain performance after 5,000+ hours of operation.
