How to avoid rollover of rotary drilling rig 

Rotary drilling rig rollover is not trivial, one will cause loss to the machine owner, two is also possible personal casualties, so we must not underestimate. How to avoid rollover rig, which is the needs of the majority of machine hand urgent concern.

1, backfill mud pools and left deep holes filling holes are not marked

The mud pit backfill, pile top marker, terrain do not overexert or afraid of trouble, the falling mast fell mast, uncertain road ahead can go straight to test machine, machine should be adjusted according to the conditions of the road drilling center.

Preventive measures: according to the road condition, the center of gravity of the drilling rig is adjusted continuously, such as the luffing position and the backward angle of the mast. Left leaning and right leaning angle of mast. Lifting height of drill pipe. Turn on the car position; if the road ahead is not clear, you can quickly lower the main volume, let the drill bucket explore the road.

2, narrow sidewalk

General roads are narrow, and when the road was almost no rain or water soaked after carrying capacity. So most overturned are false road leads (look is real, but is actually false).

Preventive measures: so it is necessary to have enough carrying capacity and enough width to walk through.

3, when drilling hole collapse

Not in accordance with the geology, groundwater or modulation of mud, high underground water level. More abundant, resulting in gradual collapse around the cylinder, until the bottom of the drill track collapsed, resulting in suspended track (surface geology is clay)

Preventive measures: hole collapse warning, should be promptly dealt with before re drilling.

4, big bed of drill is not doing a sharp turn, lashing, on a misalignment

Preventive measures: rotary drilling rig in the transport process, a parking position should be flat and hard ground, it should not be too hasty a turn.

In short, pay more attention to, obey the command! Before loading, the machine must be adjusted to the state of transport, start to adjust to the state of work, careful driving and operation generally will not happen.
