Precautions for transportation of water well drilling rig
The center of gravity of the water well drilling rig shall be balanced according to the road conditions and the site. Random drilling is prohibited in the construction site. Signs shall be made for the backfilling of the pit and pool. The mast shall be lowered and the crawler shall be retracted in narrow roads or dangerous sections. The lifting angle and left-right inclination of the mast of the drilling rig shall be adjusted in inclined sections, and the center of gravity of the drilling rig shall be adjusted by turning on the truck; When there is water on the access road or construction site, the drill pipe bit can be used to guide the machine
