HQZ400L multifunctional crawler well drill is a new,highly-effective ,energy-saving and multifunctional hydraulic drill and it is specialized in drilling well ,monitoring well, geothermal air-conditioning hole,grouting hole of the hydropower cofferdam ,grouting hole for dyke seepage control and grouting hole for base enforcement ,surface mining ,anchorage .national defense project and other drilling operations;The drill rig is equipped with hydraulic motor rotation with a high power,propulsion and lifting of cylinder and down-hole impacter with high blast pressure,to realize high effectiveness of drilling footage and low energy consumption.

1, The engine using Yuchai 95Kw turbocharged diesel engine;
2, Walking devices: walking motor with gear box, long working life;
3, The hydraulic pump: Hydraulic pump can meet the requirements of the hydraulic system for the working flow of the drilling rig. The working pressure is high, which can meet the requirements of the heavy load working of the rig and has a long service life;
4, The power head device: gearbox casting, double motor to provide power, large torque, durability, maintenance cost is lower.
5, Rig chassis: professional digging machine chassis, durable, large bearing capacity, wide chain plate, which has small damage to the hard road;
6, The lifting force: patented design compound arm, arm in small size, long stroke, double-cylinder upgrade, lifting with large tonnage;
7, Lifting arms of each rig are installed limiter to protect the cylinder safety cylinder and to protect the security of the work process;
8, Each of the hydraulic oil tube are wrapped with protective jacket, which make the oil tubes have a longer service time.
