• Specification

• Function

1.Transmitting Hydraulic Fluid: Its main function is to transfer hydraulic fluid within the hydraulic system of Komatsu machinery. It connects various hydraulic components, such as pumps, cylinders, and valves, enabling the hydraulic fluid to flow between them. This allows the hydraulic system to generate the necessary pressure and power to drive the movement of components like the excavator's arm, bucket, and other working devices.

2.Flexible Connection: The hose provides a flexible connection between different components, accommodating relative movements and displacements between them. This flexibility ensures that the components can move freely during the operation of the equipment without causing excessive stress or damage to the hydraulic connections. For example, in the complex movements of a Komatsu excavator, the hose can bend and stretch with the movement of the arm and boom, maintaining the normal transmission of hydraulic fluid.
