China Small Portable Hydraulic Engineering Rotary Drilling Rig Dr-120 for Bridge Building Railway Construction
Product Description
The maximum drilling depth of DR-120 rotary drilling rig is 30 meters, the drilling diameter is 500-1600MM,it has the function of chassis expansion and the mast can be adjusted vertically.
The mast is also equipped with an auxiliary winch to assist in hoisting the required objects.
The upper body has an automatic reset function.
It is convenient for the drill rod to be aligned with the hole, and the work efficiency is improved.
Features
1.Excellent performance, fast lifting, large lifting weight, drilling rig can be 360 degree rotary construction.
2.Full hydraulic system control can ensure that all indexes of pile foundation verticality, hole position, hole depth and sedimentation thickness meet the requirements of construction specifications.
3.Driving power is strong, the power head acts directly on the drill bit and keeps the torque unabated during piling.
4.The hole wall drilled by rotary drilling rig has good stability, complete hole cleaning after hole completion and fast construction progress.
5.Small investment,quick gains:
The utility model also has high cost performance, wide application scope and high social and economic benefits;
6.The characteristic of stabilization, credibility, speediness and high capability which makes the Rotary Drilling Rig is favored.
