Provided is a brake device (2) which has reduced manufacturing cost, is compact, and can generate sufficient braking force. Also provided is a crane (1) which comprises the brake device (2). The brake device (2) is installed in a movable body (1) which travels. The brake device (2) is provided with a receiving section (22) affixed to the movable body (1) and is also provided with a brake shoe (21) disposed below the receiving section (21). The brake shoe (21) has a brake shoe upper surface (24) provided with sloped sections (24u, 24d). The receiving section (22) has a receiving lower surface (26) corresponding to the brake shoe upper surface (24) and provided with sloped sections (26u, 26d). The brake device (2) is configured so that, when the brake device (2) is activated, the brake shoe (21) drops, and the receiving section (22) rides over the brake shoe upper surface (24) when the movable body (1) moves.

Brake equipment is provided for a vehicle adapted to travel along a path adjacent to an elongated stationary rail the brake equipment comprising a resiliently applied brake member arranged to abut one side of the stationary rail and a pivotally mounted reaction brake member on the opposite side of the stationary rail to the brake member. The reaction brake member is pivotably clear of the stationary rail along sections of the track, for example, point or crossover arrangements, pivotal movement of the reaction brake member being under the action of an abutment member arranged to abut stationary formations associated with the sections of the track.

摘要:
A vehicle is supended on a pair of slotted rails of tubular shape. The vehicle has a plurality of support members sloping downwardly from the sides of the car and having running gear thereon engaging within the rails through the slots. The vehicle is preferably of light weight materials and provided with some form of aerodynamic means to provide lift as the vehicle passes through the air along a right of way. The running gear includes rolling friction means designed to function in any event from low speed with maximum weight to negative gravity at high speeds.

A vehicle bogie or similar wheel carrying unit which carries a vehicle body and which is connected to a device which holds the carrying unit at a predetermined distance from the ground, the vehicle body and/or carrying unit being provided with means for inclination of the vehicle around a generally horizontal axis in the direction of motion of the vehicle, wherein the vehicle body in its entirety is movable on the carrying unit in generally horizontal directions perpendicular to the direction of motion of the vehicle, the magnitude of said movement being controllable by a control device engaging the vehicle body. The carrying unit is provided with means pivotally supporting swinging arms to which the wheels are rotatably connected, each swinging arm being coupled to a device which holds the carrying unit at a predetermined distance from the ground and which device consists of a first cylinder-piston device on each side of the vehicle including a pressure fluid which counteracts the moments generated by the wheel pressures via the swinging arms. The cylinder-piston devices operably connect to the control device.

An extended range, consistent force rail brake comprising an adjustable wedge assembly operatively situated between the main power spring(s) and the brake shoe(s) for selectively taking up the vertical distance that the brake shoe is required to travel between the brake release position and an initial railhead contact position. The adjustable wedge assembly is thus selectively expandable in the vertical orientation, and may comprise: an upper block that is operatively connected, either directly or indirectly, to the power spring; a lower wedge rigidly affixed to a replaceable brake shoe; and an intermediate wedge that is located by suitable bearings and/or linkages for transverse, generally horizontal slidable engagement between the upper block and the lower wedge. Each of the upper block and lower wedge elements of the wedge assembly are, respectively, located by suitable bearings and/or linkages for generally vertical translational motion (but very little, if any, lateral or longitudinal horizontal motion) within upper and lower guides provided on a frame of the rail brake.

The invention is an amusement-park device, comprising a rail-guided route course and at least one vehicle guided on the rail, which vehicle has a brake apparatus having at least one, preferably two brake pads fastened to a brake-pad carrier, which brake pads are provided for braking or clamping the vehicle at a point of the rail-guided route course during a braking event. According to the invention, the brake apparatus has a brake carrier and/or the at least two brake pads can be pivoted in relation to the stationary bike carrier. The vehicle equipped with such a brake apparatus can follow unevenness in the rail-guided route course in a simple manner, resulting in reliable braking behavior.

A locking wheeled locking carrier including a pair of identical molded half carriage parts each of which carries a pair of canted wheels to support the carrier within a track, and a pendulum part pivoted between the carriage halves and extending downward through the bottom slot in the ceiling track for suspending a desired article. The two carriage halves are slidably interfitted with one another for lateral movement toward and away from one another within the ceiling track, and the pendulum pivot extends slidably through both carriage halves. In the vertical pendulum position a camming action exerted by the pendulum on the two carriage halves forces the carriage halves laterally apart from one another so that their outside surfaces engage the ceiling track slot walls and frictionally lock the carriage in position. When the pendulum is pivoted longitudinally in either direction relative to the carriage halves and the running length of the ceiling track the lateral camming action exerted by the pendulum on the carriage halves is released so that the outer surfaces of the carriage halves disengage from the ceiling track slot wall side surfaces and the carriage is free to travel through the track, it being relockable in its new position by again moving the pendulum to its vertical position.

Brake equipment for a vehicle or mining machine which in use traverses along a path adjacent to a stationary rail comprises a rail engaging component including a wedge assembly resilient means for urging the rail engaging component into a `brake applied` mode contacting the rail and ram means for urging the rail engaging component into a `brake released` mode out of contact with the rail. The brake equipment includes further ram means for urging the wedge assembly out of a rail engaging position when the brake is released.
摘要:
A rail brake includes a rigid enclosure which mounts under a crane so as to dispose the base end of the enclosure over and adjacent a rail. A spring carriage is mounted for vertical translation within the enclosure. Springs are mounted between the spring carriage and the top of the enclosure so that the springs are compressed when the spring carriage is elevated. A brake shoe is mounted under the carriage. Actuators are mounted between the spring carriage and the base end of the enclosure. Extension of the actuators compress the springs and elevate the brake shoe from the rail. Retraction allows the springs to drive the brake shoe against the rail. Elevation of the brake shoe aligns a pair of spline joints between the sides of the brake shoe and corresponding channel walls underneath the enclosure. Removable elongate keys provide the locking splines in the pair of spline joints.
