Drawworks GH 6000 EG-AC
Roller Bearings in WIRTH Drawworks
Examples of Application Engineering
RFB 6 GB-D
The AC powered Multi-speed
gear-driven drawworks offers a
design unique to the industry,
available in a range of 1 500 HP
to 6 000 HP.
For hoisting capacities up to
3.000.000 lbs in conjunction with
optimized hook speed. This type
of drawworks is designed for the
highest level of performance to
fulfill the latest requirements of
ultra deepwater application and
onshore drilling.
The major reasons are improved
safety, optimal performance and
control, significant weight reduction
and considerably increasedreliability.
The gear-driven drawworks package
consists of the following items:
main frame, hoisting drum with
Lebus system for any wireline size,
Multi speed gear box,
compound gearbox, drive motors,
disc brake.
Eddy Current Brake. Completely
equipped with all necessary
hydraulics, lubrication, cooling,
instrumentation and controls.
Drawworks will be fully operational
from a remote location.
Standard Features
• Highest degree of performanceand efficiency
• 3 independent braking systems
for maximum safety
• Joystick operation with
4Q drive mode
• Modular, compact design in
long or short version.
• Less noise and vibration
• DNV or ABS certified
• Integrated Autodriller as
independent system
Since several years the Schaeffler KG
develops and delivers special roller
bearings for WIRTH Drawworks.
For example the Drawworks
GH 6000 EG AC is completely
equipped with FAG bearings.
The main features of this WIRTH
Drawworks are described in thefollowing chapter.
