The Bentec Top Drive is designed as transportable as well as permanent installed unit for deep drilling rigs with different mast types. The System is powered by an AC motor. The Top Drive is controlled by a separate control panel.

The standard Top Drive version includes the following items:

Hanger assembly with integrated Counterbalance cylinders

Standard washpipe

Link-tilt-system with position monitoring designed for high impacts

Remote-controlled and manual IBOP

Backup Clamp to make up and break the Top Drive drill pipe connection

Guide rail system inducing the torque within the mast.

Electrical service loop

Onboard hydraulic unit.

The blower rate for the motor cooling is variable and depends on the motor temperature.

The drives of the system have been carefully chosen to meet current noise protection regulations.

Gearbox The two-stage gearbox is helical cut with a total transmission ratio of 14:1. The speed of the engine is reduced twice before it is transferred to the bullgear (1) of the gearbox. The bullgear is located on the thrust bearing. The mainsahft is concentrically located in the bullgear and connected to it via multiple splining. The gearbox is lubricated with combined splash/pressure lubrication (3). If the gear oil has reached its maximum temperature it is piped via a bypass through an oilcooler. The oilcooler is included in the ventilation system of the motor.
