Application Scenarios

Widely used in earthmoving, quarry, sand yard, road construction and mining heavy-duty working scenarios, providing oscillating support and load bearing for front drive axle of XCMG ZL50G / ZL50GL loader.

• Thickened high-strength steel plate raw material, strong overall rigidity, resist repeated heavy impact load and avoid permanent frame deformation.
• Full penetration welding plus stress relief annealing, effectively release welding residual stress and reduce cracking risk at weld seams under cyclic load.
• Ultrasonic inspection for all welding seams, detect internal welding defects and improve the reliability of the whole frame.
• Precision machining for hinge holes and mounting lugs, guarantee good fit with hinge pins and easy field assembly and replacement.
• Strictly produced according to XCMG OEM drawings, mounting dimensions and hinge spacing perfectly match ZL50G/ZL50GL original chassis.
• Optimized structural stress distribution, smooth axle swing movement, keep four-wheel ground contact and improve loader trafficability on rough terrain.

FAQ 

Q: What is the main function of 252102179 front oscillating rack?
A: It works as swing mounting frame between chassis and front drive axle of XCMG ZL50G/ZL50GL loader, supports front axle load, allows limited swing of front axle to adapt uneven ground, keeps four wheels contacting ground, and guarantees stable traction during shoveling and travelling operations.

Q: When do I need to replace this front oscillating rack?
A: Replace promptly if the rack has obvious cracks, severe deformation, weld seam tearing, distorted hinge holes or permanent bending that affects normal front axle swing. Even tiny cracks found during routine inspection must be replaced to prevent sudden fracture under heavy load operation.

Q: Can this front oscillating rack install directly on ZL50G / ZL50GL loader?
A: Yes, manufactured strictly according to XCMG original drawing, hinge hole size, mounting lug outline and bolt hole positions fully match original chassis assembly, no secondary cutting, grinding or welding modification required.

Q: What maintenance tips for the front oscillating rack?
A: Regularly inspect frame surface and weld seams for cracks, check hinge pin lubrication and bolt tightness. Keep the hinge joint well lubricated, avoid long-time overload operation and reduce violent impact against the frame during operation.
