Applicable Scenarios

It fits XCMG ZL50G and ZL50GL loaders, mainly used in quarries, crushing yards and rock excavation sites. Suitable for loading blasted rocks, crushed aggregate and stripping hard rock. It is not recommended for low-density bulk materials such as fly ash or wood chips; general light material bucket is a better choice for these materials.

- Original matched hinge dimension with accurate lug hole spacing, direct fit for original linkage without cutting or modification
- Fully reinforced structure with extra-thick bucket root, bottom plate and cutting edge, much higher impact and crack resistance than earth bucket
- Made of NM450 wear-resistant steel for extended service life and less frequent replacement on quarry sites
- Penetration-optimized bucket shape with forward-positioned tooth adapters for easier rock pile penetration and less jamming
- Modular wear parts, rock teeth, cutting edge and side plates can be replaced individually for controlled maintenance cost
- Post-weld stress relief process delays weld cracking and metal fatigue under continuous rock impact
- Rock bucket teeth are special-purpose and not interchangeable with standard earth bucket teeth; spare parts supply is stable for quarry maintenance

FAQ 

Q：Can this rock bucket replace the earth bucket directly?
A：Hinge holes are compatible for ZL50G/ZL50GL, so it can be swapped directly. But bucket capacity, strength and bucket teeth are different, teeth cannot be mixed, select bucket according to working condition.

Q：Can I keep working if cracks appear on rock bucket bottom plate?
A：Bottom plate and bucket root are main load-bearing zones. Cracks will expand rapidly under rock impact. Minor cracks can be assessed and welded professionally; long cracks require whole bucket replacement.

Q：Can standard earth teeth be installed on this rock bucket?
A：Not recommended. Standard teeth lack impact resistance and may break easily in rock conditions. Special reinforced rock teeth are required.

Q：What operation limits after installing rock bucket?
A：Rock bucket is heavier. Do not pry large boulders or slam rocks violently, otherwise boom and linkage may suffer overload impact damage.

Q：How to reduce cutting edge wear on rock bucket?
A：Keep bucket teeth ahead of the edge to absorb main impact. Avoid direct striking of hard rocks with edge. Flip cutting edge periodically for double-side service.
