The device has two supports ( ) which can be moved in relation to each other in a transverse direction to the axis ( ) of the traction element ( ). Several clamping jaws ( ) are displaceably mounted in pairs opposite each other on said supports. The clamping jaws ( ) have surfaces which grasp the traction element ( ). When strain is placed on the traction element, the clamping jaws are displaced linearly at increasing distances except for the rear pair, in such a way that the clamping force can be evenly distributed over a great length, despite the extension of the traction element ( ). This allows, for example, steel cables with a high traction force to be tensioned without damaging the cable.

Device for fixing, tensioning or pulling an extensible traction element, in particular, a cable

At a station of an overhead cable transport installation, such as an aerial cableway, wherein the disembarking section is connected with the embarking section by a transfer section, a revolving clock conveyor travels along the transfer section. This clock conveyor is provided with entrainment members arranged thereat at a predeterminate spacing from one another and the clock conveyor is driven by the drive of a revolving cable. A further revolving conveyor travels substantially parallel to the clock conveyor along the transfer section. This further revolving conveyor is equipped with a multiplicity of driver elements distributed over the length thereof and which possesses a somewhat smaller revolving velocity than the clock conveyor. If a vehicle arrives at the transfer section ahead of time in relation to an entrainment member of the clock conveyor then this vehicle is moved further by one of the driver elements of the further conveyor until the intended entrainment member for the early arriving vehicle catches up with such vehicle and entrains the latter. The further conveyor thus prevents that vehicles positioned at the transfer section will come to standstill and specifically also in those situations when a vehicle arrives too late at the transfer section in relation to an entrainment member. In this way there can be avoided disturbances which might arise due to undesired collision of a trailing vehicle with a preceding vehicle along the transfer section.
