Power system, drawworks, mast, traveling system and driving devices of truck mounted drilling rig are mounted on a self-propelled chassis for high efficient mobilization. With more than 20 years experience of designing and manufacturing of workover/drilling rigs, SJ has developed truck-mounted drilling rigs with drilling depth of 3,280' (1000m), 4,920' (1500m), 6,560' (2000m), 9,840' (3000m) and 13,123'(4000m) which is the largest truck-mounted drilling rig, and static hook load ranging from 253000lbs (1125kN) to 505800lbs (2250kN). The truck- mounted drilling rigs feature heavy working load, reliable performance, good cross-country capability, easy mobilization and low cost, which are suitable for the drilling operation of medium depth and shallow oil well on land, desert and plateau.
Characteristics for series of truck-mounted drilling rigs：
Power system is fitted with engine and hydro-mechanical transmission.
Electric, air, and hydraulic system is centrally controlled. Key components are world famous make.
The mast design and manufacturing comply with API 4F and 8C specification. Finite element analysis and stress inspection test will be conducted for mast. The surface of structural pieces will be sand blasted.
Main drum completes with integral type Lebus groove. Main braking will be of band type or hydraulic disc brake. Auxiliary brake can be of air controlled water-cooling disc brake, air tong brake, hydro brake, electromagnetic eddy auxiliary brake. Sand drum is optional.
Chassis is powered by the deck engine via transfer case. Heavy duty wide wheel distance, high strength beam, hydraulic power steering.
Optional several humanization designs, including new-style cab, embedded stairs, automatic locking pin for mast, air controlled auxiliary brake and the guard for engine designed for different climatic conditions.
