Before and after service

Workover rigs have to be completely overhauled every 10 years. Firstly, the rig is completely dismantled. Related to a strict revision plan, diverse works at the mechanical, hydraulic and electric assemblies is carried out. After a fresh paint job, assembly and technical acceptance the workover rig is ready for the next ten years in the oil field.
