Design and Application of ES5250TJC40 Swamp Workover Rig

This paper introduces the design philosophy, main parameters and structural features of swamp workover rig suitable for workover treatment in swampland. Advanced technologies both home and abroad were used to design the workover rig which has compact structure and safe and reliable performance. The workover rig has a nominal hook load of 400KNA combined hydraulic and mechanical driving system, an all-wheel driving carrier and uses large diameter cross country tyres. Field test shows that the swamp workover rig has strong ability to move in swampland, its operating efficiency is high and less auxiliary equipments and personnel are needed.
