Product selling points

The hydraulic telescopic crawler chassis for rotary drilling rigs is adopted to meet the stability and convenience of transportation;

Cummins engine is adopted, with strong power, sufficient power reserve to meet plateau construction, and noise and emissions meet Euro III standards;

It adopts large triangle luffing structure with super stability;

The large mast section reduces the shaking of the mast during construction and improves the construction quality;

A drill pipe bracket has been installed to reduce the amount of shake of the drill pipe during construction to ensure the verticality of the drilling;

The hydraulic system uses load sensing technology to make the hydraulic system highly efficient;

Can be equipped with a variety of drilling tools to achieve both wet and dry drilling operations, suitable for a variety of foundation bored pile drilling projects. The drill rod adopts machine-locked or friction-type telescopic structure, which transmits torque to the drilling tool through tooth inlay or friction plate, which has large transmission torque and high efficiency

The main hoisting wire rope is wound in a single layer, which is easy to operate and greatly improves the service life of the wire rope. And a drilling depth detection device is provided on the main winch, and a single layer of rope makes the depth detection accurate and convenient for maintenance;

Optional transport disassembly legs for easy disassembly and transportation;

The power head adopts the company's imported reducer and motor, which has large drilling torque and high work efficiency;

An infrared camera for observing the main coil is installed, and the use of the main coil wire rope can be observed day and night in the cab;

Centralized lubrication system is equipped as standard, convenient maintenance.
