SWDM25B Rotary drilling rig

Intelligent control ensuring easy driving

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


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.

Safety protection measures

Safety protection is also taken into full consideration during designing of the rotary drilling rig of Sunward to assure customers of safety during construction.

Self-locking of handles

The dedicated electromagnetic locking handle can achieve one-key positioning of handle, which saves heavy physical manual labor.
