UltraHoist Drawworks System
UH 3G-750-3000-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 750-3000 is a fully-integrated drawworks
system, designed to be able 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 1-5/8” drill line – complete with
kickback rollers and easily removable guards
• Easily removable cable anchor
• Control system interfaces with the Zone Management
System for safe interaction with other drillfloor
equipment
• Custom PLC software ensures smooth and natural
operation for the driller
• Built-in, self-diagnostic functions with automatic
warning system 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
