Applicable Scenarios

It matches XCMG ZL50G and ZL50GL loaders, widely used in quarries, crushing plants and rock foundation construction for digging and loading limestone, granite, hard boulders and compacted soil-rock mixture. It is optimized for heavy quarry duty and not recommended for long-term handling of light materials such as fly ash and sand due to excessive dead weight and poor fuel economy.

- OEM dimensions, lug geometry fully compatible with ZL50G / ZL50GL. Direct hoist-in replacement without linkage modification
- Thick NM400 steel plus reinforcing ribs provide strong impact and tear resistance for large hard rock
- Integrated welded tooth holder design with replaceable sleeve teeth and edge protectors, cutting overhaul expense
- Stress-relieved main welds retard fatigue crack growth under repeated impact
- Precision-machined lug bores reduce pin eccentric wear and lower joint maintenance frequency
- Interchangeable wear parts including teeth, sleeves and protectors, convenient spare part planning
- Weld inspection before delivery, reliable quality for continuous high-output quarry production

FAQ 

Q：Can this 3.0m³ rock bucket fit other brands of 5-ton loaders?
A：It is not plug-and-play universal. Lug spacing, lug height and tilt bracket position are customized for XCMG ZL50G and ZL50GL. Mismatched linkage causes interference, limited bucket rotation and uneven pin load.

Q：Can small cracks on bucket bottom or side plate be repaired by hardfacing?
A：Carry out NDT first to check crack depth. Shallow short cracks can be ground out and welded with matching wear-resistant rod followed by stress relief. Long cracks near main welds or rib roots tend to re-propagate even after repair, and bucket replacement should be considered.

Q：Do bucket teeth and edge protectors have to be replaced as a set?
A：No. Bucket teeth contact rock directly and wear fastest, so teeth and sleeves can be replaced individually. Edge protectors with remaining thickness and no chipping can stay in service. Replace wear parts separately as needed.

Q：What are the key points for hoisting and installing a new bucket?
A：Lift steadily and avoid impact on bucket and lugs. Align lug holes with boom and cylinder joints gently. Do not hammer pins forcibly. Install cotter pins properly. Run empty lifting and curling cycles to check for binding before loading rock.

Q：What are the downsides of using a rock bucket for sand and fly ash?
A：Heavy plate construction reduces payload and increases fuel consumption for light materials. The tooth assembly is redundant and the dead weight wastes power. It is not economical for long-term earthwork duty.
