Abstract: An apparatus for catching a shaft conveyor means (5) in the event of overtravel of a conveyor device, including an overtravel brake device, wherein coupling devices (80,90) are provided for automatic, form-fitting engagement with one another for fixing on the brake device and on the shaft conveyor means (50).

Abstract: The invention relates to a load-compensating rope sheave arrangement for drum winders, comprising at least two rope sheaves which are vertically guided in sliding frames and mounted on hydraulically short-circuited cylinders. Multiply redundant monitoring of the different sheave loads acting upon the rope sheaves is carried out via the hydraulic cylinders which are connected to the system control of the drum winder for communication.

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: A method for regulating the speed of a clamping and lifting device (1) with at least one guide cylinder (2). A hydraulic fluid can flow in and out through in each case one opening in at least two cylinder chambers of the at least one guide cylinder (2) via at least one pump device and via at least one valve device per cylinder chamber for lifting and lowering loads (16). The degree of opening of the valve of the at least one valve device in each case can be changed as a function of the working direction of the device (1), a setpoint speed (10) and the current speed (11) of the at least one guide cylinder (2).

Abstract: The invention relates to a disk brake system for hoisting machines and winches, equipped with at least two brake circuits, wherein to each brake circuit at least one brake caliper with associated brake pads is allocated, and wherein two redundant, active control circuits (10, 12, 14, 16) are provided per brake circuit.

Abstract: The invention relates to a concealing device for the separable connection of the at least one loose drum rotatably mounted on the main shaft (11) of a conveyor machine to the main shaft (11), wherein the separable connection of the loose drum to the main shaft (11) is positively realized by means of a guided coupling wheel (3a, 3b) that is engageable and disengageable by actuating devices (7). The guidance of the coupling wheel (3a, 3b) is arranged on the sides of the loose drum.

Abstract: The invention relates to a method for producing a finished-part track for an inclined conveyor system having a conveying platform and a counterweight in opencast mining, comprising the following steps: providing a foundation; placing at least one base element, which comprises base members and cross members, onto the foundation; fastening the base element to the foundation; placing track elements onto the base element, while adjustable spacer elements, at least one respective shear cleat, and a support are arranged between the base element and track element; and orienting the track elements relative to one another, with respect to the respective base elements, by means of the spacer elements.

Abstract: Device for bearing the stator shaft of an integrated hoisting machine, with a pedestal for carrying the hoisting loads and a torque support (20) for carrying the turning load, wherein the torque support (20) consists of at least one separate torque block (30, 40) for each turning direction of the hoisting machine, each having a bearing opening (36) with a cross section of flat bearing surfaces, angled with respect to each other, for receiving a bearing section of the stator shaft with a corresponding cross section.
