TRUCK-MOUNTDE DRILLING RIG
1. Trailer-mounted drilling rig drive is divided into diesel engine drive, AC drive, DC drive and other forms,with reasonable power matching, high transmission efficiency and reliability.
2. The whole machine has compact structure, high level integration and small working space.
3. The substructure adopts telescopic or rotation type. The height, dimension, layout can be customized according to the requirements.
4. The main brake adopts band brake or hydraulic disc brake, and the auxiliary brake adopts water cooling pneumatic brake or water brake.
5. The mast is A type, K type or mobile rig mast, and it can be raised up or laid down and telescoped hydraulically.
6. The trailer-mounted drilling rig adopts the petroleum special heavy-duty semi-trailer chassis, which has good mobility and off-road performance.
7. The main engine, substructure, catwalks, generator set, pump group, solid control system, oil tank, etc all can realize the trailer transport.
