Swash plate for Terex HC230

The swash plate 0781 221 11 functions as a control element within the hydraulic axial piston pumps and motors of the Terex HC230 crane. It facilitates the conversion of rotational shaft movement into the reciprocating motion of the pistons. By altering the inclination angle of this plate, the system modifies the displacement of the pump or motor, which in turn regulates the hydraulic output, speed, and force delivered to the crane actuators. This component is integral to managing the hydraulic power required for various crane operations.

This part is designed for compatibility with the Terex HC230 model. It serves as an internal interface that manages the mechanical load and fluid dynamics within the hydraulic assembly. Proper alignment and surface integrity of the swash plate are necessary for the pump or motor to maintain consistent hydraulic pressure and flow rates during operation.

In axial piston machinery, the swash plate determines the stroke length of the pistons. As the shaft rotates, the pistons follow the angle of the swash plate, drawing fluid in during the suction phase and discharging it under pressure during the compression phase. Adjusting this angle allows the operator to vary the hydraulic output without changing the input speed of the prime mover.
