RC4 water well drilling rig is a newly developed multi-functional full hydraulic drilling rig, the rig is suitable for plains, hilly land, hot and cold regions, the machine is tracked with self-propelled chassis, available in wells, core exploration, shallow coal bed methane and other construction. It could meet to mud drilling tamping pipe hammer drilling, air-lift reverse circulation drilling and other drilling methods according to users' requirements. The rig is low labor intensity, high drilling efficiency and high security for the workers.
The maximum diameter of drilling hole - 420 mm
The maximum hole depth - 400 m
Maximum hoist capacity - 20 tone
Maximum spindle torque - 11 000 Nm
Applicable drill rod range: 2-5 inches
Full hydraulic drive
American hydraulic system
Equipped with reliable clamping system, which can easily be adjusted for height
Fast feed and lifting function reduce the time of drilling
The telescopic mast allows to use 6.1m length
Adjusting angle of power head 0-90°.simplifies loading of drill rods.
The construction of power head helps to avoid damage of the rods' thread
Lifting system on sliding supports for fixing the rig on site in difficult terrain conditions and for loading / unloading the vehicle (in the absence of the gangway)
Open/close of drilling fluid supply is controlled by hydraulic cylinder.
The rig is equipped with 4 bright LED floodlights for night work.
