An automatic loading system for vehicles includes an overhead platform, a transporting machine, and a cargo carrying mechanism. The overhead platform includes two rails. The transporting machine is disposed on the rails and configured to move on the rails along a first direction. The transporting machine includes a hoist mechanism and a fork assembly disposed on the hoist mechanism. The hoist mechanism is configured to drive the fork assembly to move along a second direction which is perpendicular to the first direction. The fork assembly includes forks disposed side by side and separately. Each fork includes at least a conveyer belt. The cargo carrying mechanism is configured to carry cargos and includes a conveyer belt platform. When the fork assembly is close to the cargo carrying mechanism, the conveyer belt and the conveyer belt platform are configured to transport the cargos to the forks from the conveyer belt platform.

The shoe derailment device for use in derailing a conductor shoe assembly of a bridge crane from a conductor rail assembly generally has a wedge head provided at a longitudinal end of a body made of an electrically insulating material, the shoe derailment device being securable to the conductor rail assembly in a derailment position in which the shoe derailment device is positioned outside an operating zone of the bridge crane, with the wedge head facing the operating zone in a manner that if the conductor shoe assembly is moved outside the operating zone, into the area occupied by the shoe derailment device, the conductor shoe assembly is derailed from the conductor rail assembly as the conductor shoe assembly engages the wedge head and is maintained in a derailed state by the electrically insulating material when the conductor shoe assembly is engaged with the body.

A system for servicing a nuclear reactor module comprises a crane operable to attach to the nuclear reactor module, wherein the crane includes provisions for routing signals from one or more sensors of the nuclear reactor module to one or more sensor receivers.

In a transport system, when transporting a suspension means other than at the time of dynamic lift-off when a package is lifted or other than at the time of landing when the package is placed, a third control means executes holding control to perform holding by a holding means, a first control means executes torque control to lower the suspension means when the load increases and to hoist the suspension means when the load decreases, at the time of dynamic lift-off when the package is lifted from the placement surface, or at the time of landing when the package is placed on the placement surface, the third control means executes release control to release the holding by the holding means, and the first control means executes the height control in which the hoisting machine is actuated to control moving the holding means to the target height.

A guide frame used for a gantry crane includes a casing, at least one first rolling component and at least one second rolling component. The casing is sleeved on a hanging arm of the gantry crane. The first rolling component is disposed at an inner side of a first side wall of the casing. The second rolling component is disposed at an inner side of a second side wall of the casing located opposite to the first side wall. The first rolling component and the second rolling component are configured to guide an object gripped by the hanging arm to move along a direction of gravity or a direction opposite thereto.
