Boom type Normal and Reverse Circulation Drill

The boom type normal and reverse circulation Drill rig is a multifunctional integrated pile driver:

1.It adopts stepless variable frequency speed regulation with 50 speeds. 

2.The positive and negative circulation methods can be switched at will. In the case of landslide-prone formations, positive circulation construction is selected. Other formations can be reversed to form holes. 

3.With crane boom, the boom can rotate 360 degrees, the assembly of the boom can be extended and retracted 13 meters long, and after construction, it can be poured and the steel cage can be lowered.

Usage and Technical Performance of Boom type Normal and Reverse Circulation Drill：

1、Normal and Reverse Circulation Drill，It integrates multiple functions into a rotary rig, which reflects a new technology of multi-purpose machine. Is the ideal hole forming machine，Hydraulic walking type、Vehicle-mounted、Tracked etc. Make the machine more usable, more flexible operation, convenient and reliable. The machine can change the drilling method (forward and reverse cycle) at any time according to the stratum variability. The stepless frequency conversion speed regulation can well solve the drilling speed requirements. Therefore, the machine is more suitable for the construction of various complicated strata such as quicksand, silt, clay, pebbles, gravel layers, weathered rocks, etc. It is widely used in constructions such as buildings, bridges, water conservancy, water wells, electricity, telecommunications, and engineering precipitation. You can complete the pouring by yourself and lower the reinforcing cage.
