UltraHoist Drawworks System

UH 3G-1250-5600-DDW

Cameron’s UltraHoistTM drawworks deliver efficient

hoisting and lowering during drilling, tripping and

handling operations. All UltraHoist drawworks are AC and

gear-driven. The three-speed version offers operational

flexibility, both at high speeds and high loads.

The UltraHoist 1250-5600 is a fully-integrated drawworks

system, designed to hoist and lower defined loads

and velocities during tripping and drilling modes. The

UltraHoist is designed for offshore installation and is

centered on maintaining personnel safety and increasing

equipment service life and long-term optimal performance

through component selection and system design.

Main Features

• Three-speed transmissions used between AC motors and

fixed speed gearbox provide unique fast line speed and

pull characteristics

• Lebus grooved drum for 2” drill line – complete with

kickback rollers and easily removable guards

• Easily removable cable anchor

• Control system interfaces with the Zone Management

System via the C-NET network to enable communication

with other system PLC, such as the anti-collision system

• Custom PLC software ensures smooth and natural

operations for the driller

• Built-in, self-diagnostic functions automatically warn for

service and overhaul of main components

• Onboard HPU systems for brakes and lubrications fitted

with dual pumps and motors

• Remote-operated fast shift mechanism in the gearbox to

avoid gear-shift problems and load-dropping

• Internal gearboxes use a keyless design to avoid stress

configurations

Safety Features

• Fail-safe braking system comprised of two brake

discs, one at each side of the drum, and two calipers

with brake pads acting on each disc

• Braking capacity of the emergency brakes equal to

200% of maximum line pull

• Automatic brake monitoring system, including brake

slip detection, drum creep detection and drum response

detection

• Two separately fused emergency shutdown circuits

• Integrated crown and floor saver provides full control of

the various braking systems
