Fetures

1.	1. Turbocharged mid-air cooled engine, more power, strong power, environmental protection and energy saving; The hydraulic pressure adopts electrohydraulic control technology;
2.	It adopts H-type hydraulic retractable track chassis and large-diameter slewing support for rotary drilling rig to meet the requirements of super stability and convenient transportation
3.	The main winding adopts single-row rope technology, which has strong lifting ability, and extends the service life of the wire rope to the maximum extent and reduces the use cost;
4.	The mast is folded before and after, with large Angle mast cylinder support and low center of gravity, so that the machine structure is more stable and the load is stronger;
5.	Using efficient endless variable, multi-gear power head, greater torque, higher reserve coefficient, stronger construction capacity, higher efficiency;
6.	Ergonomic design of the cab, multi-functional handle, comfortable seat, good sight, more comfortable operation;
7.	Hd touch display, gear knob, warping switch, start-stop switch, etc., greatly convenient operation; 360° all-round video surveillance system is safe and convenient

Application

1.This machine is applicable to slop shield piles,civil construction, new rural construction, municipal construction,and the strata contain:soil, clay, fill soil, silt, silt layer, and even some geology with pebbles, gravel;

2.Widely used in high-speed rail trestle piles, slop shield piles, photovoltaic power station foundation pile, power grids, landscaping and other projects.
