<p>A device for tensioning of a rope, the device comprising two or more sheaves (6, 6'), each sheave (6, 6') being operated by a motor (7, 7'), where a rope (10) to be tensioned may be arranged so that it sequentially rests against the contact surface of the sheaves of the device. The sheaves (6, 6') are arranged in pairs on a rotatable support (2), where the axes of rotation of the sheaves and the turntable are substantially parallel. The sheaves have a first position in which the rope (10) may pass unhindered between the sheaves (6, 6') of the pair, and be rotated by said support (2) to second position in which the rope (10) has been wound to a substantial contact angle about the sheaves.</p> |
