• High-strength thick alloy steel plate design, high rigidity and strong bearing capacity, outstanding impact resistance.
• Reinforced rib welding on stress points, effectively resist fatigue fracture caused by long-term cyclic vibration.
• Anti-rust coating protects steel substrate from mud, moisture and dust corrosion, extend service life in dusty working sites.
• OEM standard hole spacing and outline dimension, perfectly match original mounting position, simple bolt-on installation.
• Suitable for air filter compartment with moderate temperature, will not deform under normal engine operating temperature.
• Optimized structural layout, no interference with surrounding air hoses and pre-cleaner after installation.
• Stable mechanical property, not easy to deform under sudden impact load during shoveling and loading.
• Batch inspection for welding quality and dimension before delivery, avoid assembly mismatch problems on site.

FAQ 

Q：What signs mean the bracket needs replacement?
A：Visible cracks on plate or weld seam, severe bending deformation, broken mounting lugs, heavy rust thinning which reduces load-bearing strength.

Q：What should be noted during bracket installation?
A：Clean the mounting base surface before installation; align bolt holes; tighten all fixing bolts evenly; check alignment of air filter assembly after fastening. Do not over-torque bolts to prevent plate cracking.

Q：What are common causes of bracket damage?
A：Long-term vibration fatigue; collision impact during operation; serious rust thinning of steel plate; overload of air filter assembly; excessive bolt tightening torque.

Q：Can cracked bracket be repaired and reused?
A：Not recommended. Weld repair can only provide temporary support. New cracks will quickly reappear under continuous vibration. Replace new bracket once cracks or serious deformation appears.

Q：How to inspect bracket during daily maintenance?
A：Check bracket surface, weld seams and bolt tightness before heavy-load operation. Focus inspection on weld seams and bending stress areas, these positions are prone to cracking.

Q：What failures will a failed bracket cause?
A：Cracked or deformed bracket loses supporting capacity. The air filter assembly will shake violently, which may cause loosening of air inlet joints, air leakage, dust entering engine and secondary damage to connected pipelines.

Q：What maintenance suggestions for the bracket?
A：Regularly inspect bracket and fixing bolts. Clear accumulated mud and dust on surface. Treat surface rust timely to prevent continuous plate thinning. Keep air filter assembly properly fixed to reduce extra vibration load.
