Product description

XRS8/45 rotary drilling rigs are widely used for drilling of cast-in-situ concrete piles in high-rise building construction and other foundation projects, as well as foundation reinforcement and other occasions. Has the advantages of fast construction speed, environmental protection, etc.

Product highlightst

1、The non-retractable crawler chassis is connected with a pin shaft, which meets the stability of the super large tonnage drilling rig and the convenience of disassembly and transportation. The super long wheel base makes it more adaptable to the ground;

2、Adopting double large vertical board box type rotary platform structure, the operation is more stable and reliable;

3、It adopts dual Cummins QSX15 engines with mature and stable performance and good fuel economy;

4、The double drum main winding system uses four Rexroth A6VE160HD1D hydraulic controlled motors, and the reducer uses four 130 reducers with a speed ratio of 125;

5、Several forms of Drilling rods are available for construction of big holes and deep piles in hard formation,the max. depth is 110 meters;

6、The combined lifter structure realizes double wire rope lifting, reduces the diameter of the wire rope, reduces the pulling force of a single winch, and reduces the outer diameter of the drum;

7、It adopts four-wheel drive mechanism and double chain ribs, which reduces the position of the center of gravity of the whole machine, improves the stability of the whole machine, has good off-road performance and strong climbing ability.
