Product Detailed
This Engineering Drilling Rig Torque is large, the rigidity good, and the whole machine is stable and drilling efficincy high .

This Engineering Drilling RigTorque is large, the rigidity good, and the whole machine is stable and drilling efficincy high .

The major diameter filling pile drilling machine of QJ250-1 type applies to major diameter bridge pier hole in various geologic conditions, such as ravelly ground, clay loam layer, sandy gravel, breaking layer and lithosphere as well as other various major diameter pore forming construction.

This drill’s Torque is large, the rigidity good, and the whole machine is stable and drilling efficincy high and quality of pore forming is excellent. It adopts a set of drilling tool which can be used for two species of drilling technique of positive and negative circulation, it is equipped with air compressor, and can realize gas lift reverse circulation drilling.

The pile holder of ZJG260, which matches with main machinen, is equipped with five wheels tackle with two load of 600KN to move left and right on pile holder, in order to reduce the assistant time during construction; the lower plate is equipped with steel wheel device, which can move vertically and horizontally on guide rail; the upper plate can move vertically and keeps off the opening, the aiguille under 2.5 meters can enter the hole directly and is very convinient.

The drilling machine of QJ250-1 type has won Scientific and Technical Advance the First Prize of Construcion Ministry.This drilling machine has high drillng efficience,good performance,reasonable price and have good market in the world.
