A lifter assembly includes a base having a top and a bottom surface. Connectors are attached to the base extending outwardly from the bottom surface. Each of the connectors includes at least one rail wheel rotatably attached thereto. The base includes traveling wheels rotatably attached thereto. A post is attached to the base extending outwardly from the top surface to a distal end. An arm is disposed on the distal end, rotatably attached to the post, extending outwardly to a terminal end. A support is movably attached to the arm and extends outwardly to a support end. A trolley is slidably disposed on the arm and movable along the arm between the terminal end and the post. Each of the traveling wheels includes a leg pivotably attached to the base connecting the traveling wheel to the base and move the traveling wheel between a transport and a storage position.

The crane device includes: a camera provided on a hook; a camera control unit which controls an image-capturing operation of the camera on the basis of control information for operating a carrying element; and an image processing unit which processes a captured image that has been captured with the camera. The camera captures an image of the carrying destination of a baggage. The image processing unit takes, as a reference area, an arbitrary area in the image captured with the camera, generates a correction image obtained by projecting the captured image onto a plane that is parallel to the reference area and is perpendicular to an arbitrary direction with the baggage used as a viewpoint, calculates a current position of the baggage in the correction image, and displays the current position in a visually recognizable mode.

The invention relates to a method for monitoring the operation of a crane, in which an overall center of gravity of the crane, possibly with a load attached thereto, is determined and monitored in terms of its position in relation to a tipping edge of the crane, wherein possible displacements of the overall center of gravity caused by possible changes in different operating and/or influencing variables, which comprise at least different crane movements, and resultant future overall centers of gravity are determined, wherein the most critical overall center of gravity in relation to the tipping edge is determined from the determined plurality of future overall centers of gravity and a possible restriction of crane movements is determined on the basis of the position of this most critical future overall center of gravity in relation to the tipping edge.

Provided is a parking brake apparatus installable on a work machine. The parking brake apparatus includes: a parking brake switchable between a braking state of braking the turning of an upper turning body and a braking release state; a brake operation device to which a braking operation and a braking release operation for switching the parking brake to the braking state and the braking release state, respectively, is applied by an operator; and a braking control unit. The braking control unit judges whether or not a turning judgment requirement for judging whether or not the upper turning body is performing a turning motion is satisfied, and performs a braking operation invalidation control to invalidate the braking operation applied to the brake operation device when judging the turning motion is being performed.

The disclosure relates to a deflection device for deflecting a rope, comprising a roller holder, at least one deflection roller mounted on the roller holder so as to be rotatable about a roller axis of rotation, and a rope securing member spaced radially from the deflection roller for securing the rope to the deflection roller. According to the disclosure, the rope securing member is mounted so that it can be displaced along a displacement direction, wherein the deflection device comprises a detection device by means of which a displacement of the rope securing member along the displacement direction can be detected. The disclosure also relates to a working machine, in particular a crane, comprising a deflection device according to the disclosure, wherein the working machine comprises a boom with a boom head which comprises at least one deflection device over which a rope is guided.

A robot lifting arrangement is provided. The robot lifting arrangement includes a robot lifting crane that is configured to lift a substrate handling robot to an elevated position. The robot lifting arrangement also includes a track section that may extend from a chamber on the platform to an external area. Robot lifting crane may lift the robot from the chamber and transport it along the track to the external area for repair/maintenance or lift the robot from the external area and transport it along the track back to the chamber for installation into the chamber.
