Intelligent control ensuring easy driving

The advanced intelligent control system gives full play to the performance of the equipment and makes operation much easier.


Cab

The plastic profile skeleton structure is adopted for the cab, the front and top of which are covered with the high-strength panel frame shield. This way, the safety of operators is guaranteed to the maximum possible extent.

Auxiliary landing leg

The standing leg hidden below the lower mast can not only act as the auxiliary support for drilling construction, but can also help you realize other unimaginable functions.
