Claim Text:
1. A device for tensioning of a rope, the device comprising a plurality of sheaves, each sheave being operated by a separate motor having a braking capability, where a rope to be tensioned is arranged so that it sequentially rests with a contact angle against the sheave surface of the sheaves of the device, the sheaves being movable in order to vary the contact angle of the rope around each sheave, wherein the sheaves are arranged in pairs on a rotatable support, said rotatable support being rotatable between a first rotational position in which the rope may pass unhindered between the pair of sheaves, and a second, variable rotational position in which the rope has been wound to a substantially equal contact angle about the sheaves, and wherein a slewing ring in the form of a rolling-element bearing, thin in section and with a diameter of one meter or more, is arranged between the rotatable support and a stationary main body for providing a rotatable connection there between.
