product parameters

Product Name: Thickened Side Cutting Plate for Rock Bucket
Part No.: 252100734
Applicable Model: XCMG ZL50G, ZL50GL Wheel Loader
Material: High manganese wear-resistant alloy steel
Process: Thick plate rolling, integral quenching
Matching parts: High-strength bolts, nuts, spring washers
Installation: Bolt-on type
Working Condition: Ore quarrying, crushed stone transfer, compacted hard muck heavy-load operation
Inspection Items: Dimension inspection, hardness test, non-destructive flaw detection, assembly fit verification

Applicable Scenarios

It is matched with heavy-duty rock buckets of XCMG ZL50G and ZL50GL loaders, widely used in quarries and stone yards for ore, boulders and compacted hard soil. It is not recommended for light material buckets or standard earth buckets due to its heavy weight and poor cost performance under light and normal earth conditions.

- Original matching hole layout, standard bolt spacing, perfect fit for rock bucket side plates without cutting
- Thick quenched high manganese plate with excellent impact and tear resistance for long service life in quarry
- Bevel guiding design reduces stone jamming and protects bucket side welds
- Independent modular part; replace only the plate instead of the whole side assembly to save cost
- Toughness tuned for rock impact, less brittle chipping under stone collision
- Simple assembly and quick replacement to reduce machine downtime
- Compatible with matching rock edge and rock tooth sets for convenient spare parts management

FAQ 

Q：Can this rock cutting plate be fitted on standard earth bucket?
A：Holes may not align, and the heavy plate is overqualified for earth work with higher cost. Earth-type side plate is recommended instead.

Q：Can I keep working if the plate has chipped edges?
A：Chips create stress concentration. Cracks will spread quickly under repeated rock impact. Broken plates may jam stones and damage bucket side welds. Replace it promptly.

Q：How to maintain the mounting bolts?
A：Use matched high-strength bolts, tighten diagonally with spring washers. Check tightness before each shift and after blasting, because heavy vibration easily loosens bolts.

Q：What is the cooperation between cutting plate and rock side tooth?
A：Rock side tooth penetrates rock first, while the side plate diverts stones. They work as a set. Damage to one increases impact load on the other, so inspect both together.

Q：Can bent cutting plate be straightened for reuse?
A：Straightening damages quenched microstructure and reduces hardness and toughness. It is prone to cracking under shock. Replacement is safer for quarry use.
