- Manufactured strictly according to OEM drawing specifications, hole spacing and overall dimension fully match original parts, direct replacement without secondary machining, greatly shorten maintenance time.
- Made of high-strength thick steel plate and processed with stress relief, effectively eliminate internal processing stress, excellent bending resistance, not easy to bend or crack under long-term impact and vibration.
- Precision punching of mounting holes ensures uniform bolt force distribution after assembly, disperses concentrated load on frame and avoids local fatigue fracture of chassis structure.
- Heavy-duty anti-rust coating on surface, good resistance to mud, water and dust erosion, slow corrosion rate and long service life in outdoor harsh working environment.
- Designed to work with matching rubber pad, form complete damping mounting assembly, reduce rigid vibration transmission and protect high-value assemblies such as engine and cab.
- Simple installation and convenient inspection. Regular inspection of the mounting plate can prevent loose installation and avoid secondary damage to related components.

FAQ 

Q1: What factors lead to mounting plate damage?
A1：Long-term overload operation, violent impact, bolt uneven tightening, serious corrosion thinning, long-time vibration induced metal fatigue.

Q2: What signs show the mounting plate needs replacement?
A2：Visible bending, crack, severe rust thinning, bolt hole deformation and out-of-round, obvious shaking of the mounted assembly during loader operation.

Q3: What damage will be caused if the deformed mounting plate continues to be used?
A3：The load cannot be evenly dispersed, bolt force is uneven and easy to loosen. It will aggravate vibration, accelerate damage of engine or cab assembly, and even cause frame crack.

Q4: What points need attention when installing the mounting plate?
A4：Clean the contact surface before installation; use matched rubber pad; align bolt holes accurately; tighten bolts in cross sequence to specified torque.

Q5: Can the mounting plate be welded for repair after cracking?
A5：Not recommended. The mounting plate is a structural load-bearing component. Welding repair will leave hidden fatigue cracks, better replace with new plate directly.

Q6: Why use mounting plate together with rubber pad?
A6：The mounting plate provides rigid bearing support, while rubber pad absorbs vibration and buffer impact. Combined use can reduce rigid force transfer and prolong service life of whole mounting system.

Q7: What should be checked in daily maintenance of mounting plate?
A7：Check plate surface for cracks, bending and corrosion; inspect bolt tightness; confirm no displacement between mounting plate and rubber pad.
