A health monitoring system for a crane (10) includes a wheel assembly (50, 70) having a wheel (120) with an axle (160) defining an axis (172) of rotation of the wheel. The health monitoring system further includes a plurality of strain gauges (208) coupled to the axle at circumferential locations around the axis of rotation. The strain gauges continuously detect strains experienced at the wheel. The health monitoring system further includes a data acquisition system (200) coupled to the wheel that receives data from the strain gauges corresponding to detected strains. The health monitoring system further includes a main controller (204) coupled to the data acquisition system. The main controller receives data from the data acquisition system corresponding to the detected strains, uses the data to calculate loading applied to the wheel assembly continuous in real-time in both a first direction, a second direction perpendicular to the first direction, and a third direction perpendicular to both the first direction and the second direction

An operating device includes a crane controller for controlling actuators of the loading crane and for generating sensor data based on the sensor signals, and an input device spatially separated from the crane controller for inputting control commands for the crane controller. The crane controller has a first telecommunications device for exchanging data signals with the input device, and the data signals output by the crane controller include sensor data. The input device has a second telecommunications device for exchanging data signals including control commands with the first telecommunications device. The input device has a transmitter device for outputting data signals. A signaling device is spatially separated from the input device, and has a receiver device for receiving data signals output by the transmitter device and a display device for displaying audio data and/or image data. The signaling device signals the audio data and/or image data to a user.

A method for hoisting and transporting assemblies in an underground nuclear power plant, the method including: 1) pouring concrete onto a reactor cavern to form a rock anchor beam; hoisting a circular bridge crane to the reactor cavern through a hoist shaft on a top of the reactor cavern; mounting the circular bridge crane on the rock anchor beam by using a truck crane; 2) installing a containment cylinder and a track beam of a polar crane in the reactor cavern using the circular bridge crane; hoisting a gantry crane on one end of a polar crane girder and sending the polar crane girder to the reactor cavern; hoisting the other end of the polar crane girder using the circular bridge crane; allowing the polar crane girder to be horizontal; and mounting the polar crane girder on the track beam.

A virtual driving system for efficiently testing an interlock operation is provided. The virtual driving system comprises an optical cable installed on a rail; a transport cart for driving in place on the rail and communicating with the optical cable; a first collision avoidance control unit set to correspond to a first virtual path of the transport cart; a second collision avoidance control unit set to correspond to a second virtual path different from the first virtual path of the transport cart; a signal line distribution unit for selectively connecting any one of the first collision avoidance control unit and the second collision avoidance control unit to the optical cable; and a simulator for controlling the first collision avoidance control unit, the second collision avoidance control unit, and the signal line distribution unit according to an operation scenario of the transport cart.

A mounting assembly for a cross-rail of an overhead rail system includes a mounting rail, an attachment bracket, and a spring-loaded pin. The mounting rail is configured to mount to a sidewall and includes a bracket receiving recess. The attachment bracket includes an attachment portion and an extension portion, wherein the attachment portion is shaped to correspond to the bracket receiving recess such that the attachment portion is positionable within the bracket receiving recess. The spring-loaded pin is coupled to the attachment bracket and includes a retracted position and an extended position, wherein the spring-loaded pin is biased to the extended position to lock the cross-rail to the extension portion of the attachment bracket.

A support for a trolley, having a running surface that is formed on the support for the trolley, an upper chord, a lower chord and braces that connect said chords together, wherein the braces are designed to be flat, and each brace has a main surface that faces away from the support longitudinally between the upper chord and the lower chord. Two of the braces form a brace pair in each case and are arranged next to one another as viewed in the direction of the longitudinal axis of the support, preferably on the outside of opposite longitudinal sides of the support. To provide such a support, the flat braces are releasably secured to the upper chord and/or to the lower chord. The invention also relates to an overhead transport device having such a support and a trolley that can be moved along the support on the running surface.
