Jereh truck/trailer mounted workover rig is mechanically and hydraulically driven. The power system, drawworks, mast, travelling system and transmission mechanism of the workover rig are mounted on the self-propelled chassis, which improves the moving efficiency greatly. Now, Jereh truck mounted workover rig series cover the workover depth from 2500m to 7000m and drawworks power from 250HP to 1000HP, featuring high operation load, reliable performance, excellent off-road performance, convenient movement and low operation/moving cost. Besides, workover rigs for arctic, desert and highland applications are available.
Conform to API Q1, 4F, 7K and 8C Specification and API monogrammed.
The technical parameters and overall design conform to GB/T 23505 Petroleum Drilling and Workover Rigs.
Conduct strength analysis for the mast and substructure based on SAFI software.
Modular design achieves fast move and transportation.
Mechanical transmission, simple operation and easy maintenance.
Special off-road chassis extends service life.
