FAQ

I. Excavator Bucket Category
1.The service life of the excavator bucket is far lower than expected. Which operations are most harmful to the bucket?
It is prohibited to use the bucket to drop and impact rocks (it is likely to cause deformation and cracking at the connection between the bucket and the boom arm); avoid prying objects with the back plate of the bucket (the lever principle makes the bucket teeth bear several times the pressure, resulting in fracture); do not use the slewing force to hit objects (it will damage the side plate, pin shaft and frame).

2.How to reduce the wear of the bucket during rock work?
Give priority to using the reinforced rock bucket (thickened plates and wear-resistant steel plates); when operating, keep the bucket fixed to the boom arm, and use backward dragging instead of vertical hitting; regularly check the wear of the bucket teeth, and replace the side teeth and skirt teeth in a timely manner.

II. Rotary Drilling Rig Bucket Category
1.How to select the rotary drilling rig bucket according to the geological conditions?
Soil layer/soft rock layer: Double-bottom sand-sucking bucket (suitable for silt, clay, and fully weathered rock);
Cobblestone/moderately weathered rock layer: Rock-embedded double-bottom sand-sucking bucket or double-layer cylinder drill (for compacting cobblestones);
Hard rock breaking: Joint construction of cylinder drill circular cutting + rock-embedded spiral drill bit.

2.How to prevent hole collapse during rotary drilling construction?
Keep the height of the mud liquid level stable (maintain the pressure on the hole wall); deal with it immediately when bubbles or slurry seepage occur around the casing; during the shutdown period, keep the drilling rig away from the soil-taking slope and park it on a solid flat ground.
3.How to predict the stuck drill rod or the drill rod being carried in advance?
Observe whether the main hoist depth gauge matches the position of the drill rod joint; monitor the rotation speed of the drill rod (the rotation speed decreases when the load is high); after lifting the drill rod, check whether the type of drill cuttings is consistent with the stratum.


III. Light and Small Hoisting and Handling Product Category
1.How to extend the service life of the handling equipment in the mining scenario?
Clean the hydraulic valve group every day to prevent dust jamming; select wear-resistant steel wire ropes; it is strictly prohibited to pull obliquely during hoisting (to avoid structural deformation caused by the shift of the center of gravity).

2.How to quantify the risks of overloading operations of mobile handling equipment?
Overloading by 10% can reduce the fatigue life of the steel structure by 50%; when pulling heavy objects obliquely, the lateral force borne by the track can reach twice the vertical load, which is likely to cause the track to deform.


IV. General Maintenance and Safety Category
1.How to prevent the cracking of the welded parts of the excavator bucket/drilling bucket?
Regularly check the welds of the bucket back plate and the hinge shaft; avoid overloaded prying operations; at the initial stage of cracking, use low-hydrogen electrodes for repair welding and reinforce the stress concentration points.

2.What are the risk points in the daily operation of light and small cranes?
The load shall not exceed the rated weight (the mobile gantry crane needs to balance the center of gravity); it is prohibited to pull heavy objects obliquely (it will cause the track to deform); regularly check the brake and limit switch of the electric hoist.
