The invention relates to a catch device (38a-38K) on the load suspension means (2; 2a; 2b) of a lift system (100; 100a; 100b), comprising a braking device (300; 300a) which interacts with a guide rail (7b-7e) of the load suspension means (2; 2a; 2b). The braking device (300; 300a) comprises a cam disk (55; 55a) which can be rotated about a cam disk axis and which is caused to activate the catch device (38a-38d) to rotate about an activation angle of rotation, wherein the cam disk (55; 55a) is designed in such a way that the cam disk, as a result of the rotation about the activation angle of rotation, comes into contact with the guide rail (7b -7e), whereby the guide rail (7b -7e), which moves relative to the catch device (38a-38d) when the load suspension means (2; 2a; 2b) is travelling, rotates the cam disk (55; 55a) into a position into which the braking deice (300; 300a) and hence the catch device produces an intended braking action with respect to the guide rail (7b -7e). The catch device (38a-38d) comprises an electrically controlled activating mechanism (45; 45a) with a pivotably mounted activating lever (47; 47a) and an activating spring (52) which, if required, causes the cam disk (55; 55a) to rotate about the activation angle of rotation via the activating lever (47; 47a). |
