Introduction and application notes
SJ is the largest workover equipment manufacturing base in China,with a full range of self-propelled workover rigs with a maximum hook load of 600kN~2750kN. We have developed various fast moving,efficient, and energy-saving new products that meet different environmental and operational requirements. We have produced and sold more than 2000 truck-mounted workover rigs, including 834 units exported to over 30 countries and oil producing regions around the world. We are the largest manufacturer in terms of production,sales, and export volume in China.
What this model is built to handle
When this model is shortlisted, the practical check is whether the workover rigs supports the target duty without extra handling risk.
If the project already has a clear target for working capacity, power arrangement, this page becomes easier to use because the remaining checks are mostly about layout, control, and installation limits.
A stronger purchase case usually appears when the model gives a clearer answer on balanced field capacity, service access, and the local delivery plan.
What buyers usually compare
Layout and handling
The field-deployable format reduces setup friction when the site needs a compact footprint.
Capacity boundary
Buyers should start with working capacity and power arrangement because it defines the usable duty range.
Control package
The control package is arranged to match field-side decisions without unnecessary manual steps.
Maintenance access
Field service is simpler when the main components remain accessible after installation.
Where the package fits best
Typical duty
well servicing campaigns across land or desert blocks where a field-deployable format matters.
Field condition
The model is more suitable when field operation is part of the job requirement.
Project scenario
workover projects that need efficient rig-up and consistent pipe handling with field-side control and stable handling.
Main assembly and field interfaces
Principal unit
The main assembly carries the workover rig package function and defines the working layout of the unit.
Control system
The control package is tuned to keep the operator's tasks clear and the sequence consistent.
Mobilization format
Transport and setup remain important because the package has to fit the actual field logistics.
Field interfaces
Shared interfaces, hoses, cable points, or load paths should be checked together with the main specification.
