Applicable Scenarios

It is suitable for XCMG ZL50G and ZL50GL loaders, mainly used in quarries, crushing plants and rock foundation excavation sites for granite, limestone, boulders and compacted hard soil. It is not recommended for grain, wood chips or fly ash. Its heavy dead weight leads to low efficiency and high fuel consumption for light bulk materials.

- Standard OEM hinge dimensions, perfect fit for original linkage pins, no cutting modification during swap
- Thick NM400 plate with double reinforcement for excellent impact and tear resistance and long service life in quarry
- Integrated welded tooth holders deliver higher shock resistance than bolted holders
- Quick-change sleeve tooth design reduces machine downtime for tooth replacement
- Short rock bucket profile for powerful penetration and less stone jamming
- Modular wear parts; edge, side plates and teeth can be replaced separately to cut maintenance cost
- Mature spare parts system for sleeve teeth and side plates, easy stock management

FAQ 

Q：Can this welded sleeve-tooth rock bucket be used for fly ash or wood chips?
A：Not recommended. The bucket itself is heavy with poor fuel efficiency for light materials. Use dedicated light material bucket instead.

Q：Can I keep working with tiny cracks on welded tooth holders?
A：Tooth holders bear major impact load. Cracks expand rapidly under rock impact and may damage adjacent edge and side plates. Inspect and repair promptly.

Q：Why do sleeve teeth fall off frequently and how to fix it?
A：Common causes are worn lock pins, dirty mating surfaces and excessive wear between tooth and holder. Clean contact surfaces and install new lock pins. Replace holders if inner sleeve is heavily worn.

Q：What is the difference between welded holders and bolted holders?
A：Welded holders provide better integrity and impact resistance for hard rock. Bolted holders are easier to remove but bolts tend to stretch, loosen or break under repeated heavy shock.

Q：Can small cracks on bottom plate be welded directly?
A：Cracks must be fully ground and inspected before welding. Use matching wear-resistant welding rods and conduct stress relief. Replace the bucket if cracks are long or near root welds.

Q：Can this rock bucket swap with standard earth bucket?
A：Hinge holes are compatible. Always match bucket type with working material. Earth buckets will fail quickly under rock load.
