BUK-80 Lifting rig for well development and workover


BUK-80 Lifting rig for well development and workover

BUK-80 is designed to perform tripping operations during oil and gas wells development and repair, to perform rotary drilling, as well as other types of work during development and repair of wells. The rig can operate in temperature between -45°С to +40°С.


Key features

- The equipment is mounted on a tri-axle semitrailer and fully meets the maximum allowable axial loads and dimensions requirements for public roads use;

- The rig is powered by a YaMZ-238M2 naturally aspirated diesel engine;

- The rig can be equipped with a gear-driven drawworks and a three-speed gearbox or a double-chain drive drawworks with quick switching pneumatic couplings.

Basic equipment:

Transport base - tri-axle semitrailer; YaMZ-238M2 diesel engine with a 5-speed gearbox; 2×250 litres fuel tanks; Two-section telescopic mast, cable extension mechanism works with a hydraulic winch; Mast upper section fall prevention mechanism against extension cable breakage; Gear-driven single-drum cargo winch; Drilling line system; Hook block; Auxiliary winch with a 3 t lifting capacity; Rotor chain-drive manual transmission (topped with a sprocket located in the back of the car to the right of the travel direction); Hydraulic system for a hydraulic rotor or a hydraulic key; Hydraulic tank with exhaust-based heating system; Hydraulic cathead; Pneumatic system powered by the YaMZ-238M2 engine’s standard compressor; Power cabinet with a 380/24V transformer; Drilling parameters monitoring system (IVE-50 with a hook load sensor); Stationary driller’s console (in the back of the machine on the left side); 4 hydraulic outriggers for setting up the rig; Support pedestals with platforms for hydraulic outriggers; Fencing, folding aisles, stairs.
