BENTEC Developed New Generation Drawworks: BENTEC E-1250, 1500, 2000 - AC / DC

The BENTEC E Drawworks is the latest generation of drawworks. 

The entire range of BENTEC E Drawworks has been developed based on a single standard technology complying with the most rigorous market requirements.

DC drive SCR control BENTEC E Drawworks can be manufactured to the customer's request.

This new generation equipment features small dimensions, reduced weight, heavy load base frame and no chain transmissions.

The new BENTEC E Drawworks consists of two main electric drives, two-speed transmission, drawworks drum and mechanical parking brake as well as the main electromagnetic brake. BENTEC anti-collision system (ACS) reduces the risk of a traveling block equipment collision with the crown block and the rig floor. Drawworks are remotely controlled with a joystick.

The two-speed transmission with lubrication system is driven by two stand alone electric oil pumps fitted with a filter and electric preheating system.
Speed change is controlled with the help of pneumatic cylinders.
  Drill bit automatic feed system provides for the following functions:

- automatic drilling;
- emergency hoisting, including derrick hoisting;
- LEBUS grooved drawworks drum;
- fail-safe pneumatic disk brake is used as a parking brake;
- electromagnetic brake in combination with drive motors provide for service brake functions. Air cooling is available.

Bentec E Drawworks are 4Q controlled. The driller controls the speed of tripping with a joystick. During drilling the smooth feed is controlled automatically with regard to the following four parameters:

- ROP;
- WOB;
- РР, or
- POOH.

These drawworks have been used successfully in Russia at KCA Deutag drilling rigs and in future will be supplied with four train-type drilling rigs that are currently being manufactured by BENTEC for EURASIA drilling company (Russia).
