650HP mobile service rigs are truck-mounted
drilling equipment which are researched and developed by ZYT Petroleum
Equipment Co., Ltd independently.
Max static load of mobile drilling rigs is
1470KN. With the adoption of numbers of patented technology, the power system
adopts CAT engine C18+ Allison M6620AR gearbox. The chassis adopts 12 x 8 drive
and the weight of whole rig is distributed rationally.
The mobile service rigs are widely used in
onshore oil fields of deep well overhaul, workover, oil test, salvage and pump
inspection operation.
Features
1. The 650HP mobile workover rigs adopt 12×8 self-propelled chassis.
2. Drawworks' main brake of mobile service rigs adopts hydraulic disc brake system and its auxiliary brake adopts Eaton pneumatic water-cooled disc brake.
3. Finite element analysis and design is adopted on mast, frame and drawworks to reduce the weight of the rig.
4. It adopts 5+5R anti-reverse rotary table transmission device.
5. Parallelogram substructure of mobile service rigs has stable structure and is easy to install.
