portable drill rig
ST1005G Mobile drill is one kind of rotary drilling equipment installed on the classis of EQ1141NBJ diesel
truck, the truck meets the China Ⅲ emission standard, the drill equipped with transpose positions and
auxiliary hoisting device, drilling fed by hydraulic oil pressure.
St100-5G mobile Drill
1. Application Range
(1) Exploration in shallow holes of mine, and seismic exploration drilling
(2) Drilling holes in liquids and natural gas exploitation
(3) Drilling holes for construction blasting
(4) Geological exploration and shallow water well drilling
2. Main features
(1) having hydraulic pressure and high ability of pulling down and pulling up, the operation is easy and secure.
(2) The main hoist provided is planetary hoisting. The operation are easy, safe and reliable, the auxiliary hoisting device provided impacting operating
(3) The mud pump is high self-adsorb ability and can be regulated 10 kind flows.
(4) Rotary table can automatic transpose position to get out off the holes, thus the labor intensity is reduced and the drill’s service life is prolonged.
(5) The driver rod has high rigidity, weightier, being pressure by self-weight.
(6) Having hydraulic mast and four stabilizers, convenient in operation.
(7) Long feeding stroke,auxiliary time reduced, drilling efficiency improved.
(8) The cab of this equipment is sealed bi-rows cab,capacity of this cab is 6 persons.
