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.
