A device for controlling a brake of a drum of a draw-works equipping a drilling rig operating a drill tool in a borehole, the device comprising:
- a brake lever having a first end connected mechanically to brake bands designed to act on said drum and a second end provided with a first brake control handle, said device further comprising actuation means configured to be controlled and arranged to act mechanically on said brake lever, and a second brake control handle arranged to servo-control said actuation means.
A method of controlling a brake control for controlling a brake of a drum of a draw-works equipping a drilling rig operating a drill tool in a borehole, which method implements a brake control, said brake control comprising a brake lever having a first end connected mechanically to brake bands designed to act on said drum and a second end provided with a first brake control handle, said method comprising:
- applying a mechanical force to said brake lever, said applied force being controlled to procure servo-control of the position of said brake lever and/or of a thrust force exerted on said brake lever.
