Purpose:
Repair of oil & gas wells.
Operations performed:
- mobile moving from well to well;
- assembly and disassembly of control head equipment;
- round trip including those with sucker rods and tubing;
- accident elimination.
Design features:
- single-drum winch with one single-disc pneumatic friction clutch;
- upper section of derrick is moved up by hydraulic winch from the remote control console;
- device for fixing hook block and protection of the derrick from damage when moving the rig;
- double-action hydraulic jacks for leveling the rig.
