Abstract: A stop arrangement having a first brake lever arrangement and a second brake lever arrangement, which together form a brake lever pair of a brake caliper arrangement and which, at the first end thereof, are respectively articulated on a support and, at the second end thereof, are coupled to one another by means of a positioning arrangement, wherein a first stop element is arranged in each case between the ends of the first brake lever arrangement and a second stop element is arranged between the ends of the second brake lever arrangement, and first and second stop elements are formed and mesh in such a way that they allow operating movements in opposite direction towards and away from one another between a brake position and a releasing position of the brake lever arrangements and inhibit an aligned tilting movement of the brake lever arrangements in a tilting direction (M), such that the brake lever arrangements are retained in the releasing position against a tilting action in a centering position within a

Abstract: A control and regulation arrangement for protection of a conveyor or other hoisting or crane device that assures a safe reaction to overloading. A brake apparatus is provided that acts on the conveyor under control of an overload sensor. If the load approaches a predetermined threshold, a signal is emitted from the overload sensor and transmitted to a speed sensor that limits the conveyor speed. Simultaneously the control transmits a signal to the brake apparatus to actuate and stop the conveyor. Upon receipt of a subsequent signal that a load relief state is to be established, the control brakes the conveyor in accord with the speed signal such that the object in transport moves toward a safe position at a constant speed. A conveyor with multiple hoisting devices may include duplicate control and regulation arrangements for each hoisting device.
