1. When preparing for work, pay attention to:
1. How much fuel
2. How much coolant
3. How much lubricating oil
4. How much hydraulic oil
5. Parts that are maintained according to the shift
2. Attention should be paid to the following when starting the work:
1. The hand accelerator and foot accelerator should be in low gear
2. Wear of main and auxiliary wire ropes
3. Whether the wire rope stress releaser [universal joint] rotates flexibly
4. Is there any abnormality in starting the engine?
5. After the engine is started, it should run at medium speed for 5 minutes
6. Whether all alarm devices have been disarmed
7. Whether there is oil leakage or water leakage in each part
8. Is there any abnormality in the structural part of the working device?
3. Pay attention when starting drilling:
1. Understand the construction work environment and whether there are obstacles around
2. Understand the situation of mud and site leveling
3. The foundation condition of the location where the drilling rig is located, and whether the construction site meets the equipment stability of the drilling rig construction! Whether a circuit board is required
Fourth, the drilling rig operation should pay attention to:
1. At the beginning, the drill bucket should slowly fall, and then start to drill. 2-3 meters on the ground, pay great attention to whether the center of the pile deviates
2. When the drill pipe falls, it is necessary to control the speed to prevent the rope from being messed up.
3. When using the pressurizer, do not pressurize blindly, and control the coordination with the rotation speed of the drill pipe to prevent the drilling from slipping.
4. Do not lift the drill pipe hard when drilling, release the reaction force of the soil layer and then lift it
5. Other notes:
1. Do not talk to people when the rig is operating
2. The operator shall not leave the cab when the drilling rig is running
3. When the operator leaves the drilling rig, he should put the drill pipe to the ground and turn off the flame! Lock the door and turn it!
