  Workover rigs AM12 / 40 and AM12 / 50 for loads up to 40 ft, respectively 50tf are used for interventions and overhauling works of oil and gas wells, in order to perform the following operations:

- Introduction and extraction of pumping rods, oil tools, sucker rod pumps
- Mounting and dismounting the wellhead
- Repair and remediation in the well such as milling plugs, sand wash, instrumentation etc.
- Bailing
- Swabbing

  The rig is installed on a chassis with four axles Roman 8X6, with very good manoeuverability on difficult terrain. The rigs meet all legal standards for transport on public roads.

  Power is provided by a CATERPILLAR C9 ACERT diesel engine, with an automatic transmission CATERPILLAR TH31.
