one.Crawler variety and hydraulic management, simple to go and run

2. it can work with immediate circulation mud pump and reverse circulation pump , also can operate with air compressor.

3. it is employed for h2o well drilling, mining blasting gap, foundation piling gap designand so on.

4.extremely powerful motor , 160KW (218HP) Commins diesel motor

five.it can drill complicated stratum ,like kinds of tough rock,clay ,sandy ,cobble and so on

Primary Features

1.Rig kind of optional geared up with large leg for self loading Crawler and truck sort, optional diesel engine or motor electricity.

2.The combined pump transfer case, hydraulic rotary energy head, the motor chain propeller, h2o pump, mud pump parts this kind of as hydraulic configuration, affordable electricity matching, speed, strain regulating block stepless adjustment, obtain a assortment of drilling parameters, fulfill a variety of drilling technology, adapt lo the total formation drilling demands

3.Several drilling technologies: the soil and sand pebble mattress reverse circulation drilling. Moisture rock combination of big diameter DTH hammer drilling composition. All air leakage development drilling a gap deep casing to stick to up. Deep hole h2o, gasoline, three intricate strata blend DTH hammer drilling mud.

4.Patent method: rock hole diameter of 600 mm, humidity mixture of DTH hammer drilling, conserve fifty% use air compressor, enhance the efficiency of twenty%. 300 mm diameter drill 800 m deep h2o, fuel, DTH hammer drilling mud 3 medium combinations, substitute roller rock drilling, increase the speed by 200%

five.Substantial force mud pump, optimistic and negative circulation pumps, drilling body carry ing, drilling platform opening and closing, the drill pipe discharge, leveling, winding, drill leg wander all with auxiliary movement of the controlled by hydraulic, this kind of as strengthening development effectiveness. Decrease the depth of the operator operate.

six.CZPT program geared up with independent air-cooled hydraulic oil cooler,and can optional set up h2o cooler to guarantee hydraulic technique keep constant and effective operation beneath the higher-temperature temperature situations of different areas.
