• Specification

• Functions

1.Structural Stabilization
They secure heavy components (engine flywheel housing, hydraulic pump) to the machine’s main frame, preventing lateral or vertical movement during digging, lifting, or swinging—critical for avoiding misalignment of rotating parts (e.g., transmission shafts).

2.Vibration Damping
The integrated damping pads absorb vibrations from the engine and hydraulic system, reducing noise and minimizing wear on adjacent parts (e.g., gaskets, bearings). This extends the service life of both the supported components and the frame.

3.Load Distribution
They evenly distribute the weight of high-mass parts across the frame, preventing localized stress concentrations that could lead to frame cracking or component failure under heavy loads (e.g., lifting large boulders).
