Frequently Asked Questions
How can I reduce the wear of the bucket during heavy rock work?
Prioritize using reinforced rock buckets with thickened wear-resistant plates. During operation, keep the bucket fixed to the boom arm and use backward dragging instead of vertical hitting. Regularly inspect and replace side teeth and skirt teeth to maintain efficiency.
What operations are most harmful to an excavator bucket's service life?
It is prohibited to drop the bucket to impact rocks, as this causes cracking at the connection points. Avoid prying objects with the back plate, which puts excessive pressure on the teeth, and never use slewing force to hit objects to protect the side plates and frame.
How do I select a rotary drilling rig bucket based on geological conditions?
Use a double-bottom sand-sucking bucket for soil or soft rock layers. For cobblestones or moderately weathered rock, a rock-embedded double-bottom bucket is preferred. Hard rock breaking requires a combination of cylinder drill circular cutting and rock-embedded spiral drill bits.
What are the main risks of overloading mobile handling equipment?
Overloading by just 10% can reduce the fatigue life of the steel structure by 50%. Additionally, pulling heavy objects obliquely can double the lateral force on the tracks compared to vertical loads, leading to permanent structural deformation.
How can I prevent the cracking of welded parts on excavator or drilling buckets?
Regularly inspect the welds on the back plate and hinge shafts. Avoid overloaded prying operations. If cracks are detected early, use low-hydrogen electrodes for repair welding and reinforce stress concentration points immediately.
What maintenance is required for handling equipment in mining scenarios?
Clean hydraulic valve groups daily to prevent dust jamming and use wear-resistant steel wire ropes. Strictly avoid oblique pulling during hoisting to prevent structural deformation caused by center-of-gravity shifts.
