▪ Adopt high-strength low-alloy steel as raw material, with excellent comprehensive performance of strength, toughness and fatigue resistance. It can continuously withstand alternating torsion and impact load generated by uneven road surface, and is not easy to crack or permanent deform under long-time heavy-load operation.
▪ Adopt robotic automatic welding process, with uniform weld penetration and stable molding. Key load-bearing welds are inspected by ultrasonic flaw detection one by one to eliminate hidden dangers such as pores and slag inclusion, greatly improving the reliability of the welding structure.
▪ Professional stress relief treatment after welding, which effectively releases welding internal stress, reduces the gradual deformation of the workpiece after long-term use, and avoids the problem of pin hole misalignment caused by welding deformation.
▪ The hinge pin holes and axle installation surface are precisely machined, the coaxiality and flatness meet the original technical requirements. Perfect matching with rear axle and rear frame, direct assembly without secondary cutting, welding or reaming modification.

FAQ 

Q1: What is the function of the oscillating bracket?
A1: It is the swing support between rear frame and rear axle, enabling the rear axle to swing freely within a limited angle, keeping rear wheels grounded to ensure traction and driving stability on bumpy roads.

Q2: When should the oscillating bracket be replaced?
A2: Replace it when the main weld cracks, the bracket is twisted and deformed, the hinge hole is severely worn and out-of-round, or multiple repair schemes cannot meet the assembly requirements.

Q3: Can this oscillating bracket be installed on other loader models?
A3: It is specially matched for ZL50G and ZL50GL. Do not install it on other models without confirming the drawing and installation dimension.

Q4: What should be paid attention to during installation?
A4: Clean the fitting surface and pin holes before assembly; check the matching oscillating pins and bushings; control the swing clearance after installation and tighten the connecting bolts according to torque standard.

Q5: Can cracked oscillating bracket be welded for reuse?
A5: Minor surface cracks on non-key areas can be professionally welded. If the main stressed beam or hinge hole is deformed and cracked, replacement is recommended for safety.

Q6: What are the common reasons for oscillating bracket damage?
A6: Long-term driving on bumpy roads, frequent impact during shoveling and loading, overload operation, lack of lubrication leading to pin seizure and abnormal stress concentration.

Q7: Does the product include rear axle and oscillating pin?
A7: Only the oscillating bracket is provided. Rear axle, pins, bushings and gaskets need to be purchased separately.
