• Specification

• Function 

1. Vibration Damping & Noise Reduction
This is its primary function. The resilient mount is typically installed between high-vibration components (e.g., the engine, hydraulic pump, or transmission) and the machine’s main frame/chassis. It uses its elastic material (often rubber composites or reinforced elastomers) to absorb and dissipate vibrations generated by the operation of power units. By reducing the transfer of high-frequency or low-frequency vibrations to the chassis, cab, and other structural parts, it minimizes operational noise (critical for operator comfort) and prevents "resonant vibration" (which can amplify wear on nearby components).

2. Shock Absorption for Dynamic Loads
During heavy-duty operations (e.g., digging, lifting, or traveling over rough terrain), Komatsu equipment experiences sudden dynamic shocks (e.g., impact from bucket contact with hard soil/rock, or jolts from uneven ground). The resilient mount acts as a "buffer": its elastic structure cushions these sudden shocks, reducing stress on rigid components (such as bolts, frame welds, and engine housings). This prevents premature fatigue or cracking of structural parts, extending the overall service life of the machine.
