Abstract: The invention relates to a plugging device for releasably connecting the drum wheel (2) of the at least one loose drum rotatably mounted on the main shaft of a winding engine, said drum wheel being rigidly connected to the loose drum, to the shaft wheel (4) which is rigidly connected to the main shaft. The releasable connection of the drum wheel (2) to the shaft wheel (4) is carried out in a formfitting manner by means of an engageable and disengageable sliding wheel (6) which is guided on a shaft wheel (4). Actuations (10) are carried out in points in a distributed manner over the circumference of the sliding wheel, said actuations acting directly on the sliding wheel (6), in order to engage and disengage the sliding wheel (6).

Abstract: A traction sheave clamping device for detachably fixing ropes to the traction sheave of a Koepe hoist, having at least one clamp crossbeam, at least two anchoring elements for engaging in wedge-shaped or hook-shaped grooves in the face sides of the traction sheave/cable chuck rim sheets, and stud bolts for connecting the anchoring elements to the clamp crossbeam, wherein the anchoring elements and the traction sheaves have corresponding torque support surfaces extending substantially in the pull direction of the stud bolts, wherein the extension of the torque support surfaces in the pull direction of the stud bolts is a multiple of the distance between the stud bolt center axis and the anchoring point.

Abstract: The invention relates to ventilation openings (10) integrated in at least one side plate (20) of the cable carrier (15) of a hauling machine (1). An electrical apparatus (35) is arranged in the interior of the cable carrier (15). A first air guide (30) covers the ventilation openings (10) in the side plate (20). The first air guide (30) is arranged for interactive air exchange with a second air guide (25), wherein the first air guide (30) is movable relative to the second air guide (20).
