Automated system for positioning and supporting the work platform of a mobile workover and well-servicing rig

A method of positioning and supporting a work platform of a mobile rig at a drilling site comprising:

• connecting one or more support beams to a drilling mast of the mobile rig, wherein one or more of the one or more support beams have a plurality of pin holes;
• connecting a movable support structure to the one or more support beams by one or more support rollers, whereby the one or more support rollers are designed to roll along the one or more support beams such that pin holes on the movable support structure can be aligned with the pin holes on the one or more support beams at a desired height;
• movably connecting a work platform to the mobile rig by the movable support structure;
• providing a lifting mechanism for raising or lowering the movable support structure;
• connecting one or more support cylinders to the movable support structure on one end and to the work platform on an opposite end;
• providing one or more automated pinning systems for pinning the movable support structure at a desired height along the one or more support beams;
• positioning the mobile rig at the drilling site;
• actuating the lifting mechanism to position the movable support structure at a desired height;
• actuating the one or more automated pinning systems to pin the movable support structure at the desired height;
• actuating the one or more support cylinders to pivot the work platform downwardly to a horizontal position above the drilling site.
