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.
