A method for controlling a movement of a load in a workspace by a control device, including a) acquiring target coordinates to be set of a target point in the workspace towards which a load pick-up apparatus is to be moved, b) determining a load measured value by measuring the weight of the load using a load measuring device, c) determining actual cable lengths of positioning cables, d) determining desired cable lengths to be set by the respective positioning cable winch, for the positioning cables for the target coordinates of the target point to be set and for the current load measured value, and for each of the positioning cables, the control device searches a database for a data set that matches the target coordinates of the target point that are to be set and the current load measured value, and determines the desired cable length to be set.

Method for controlling a movement of a load in a workspace of a load transport device

A load transport system having a load carrier and at least one load receiving device which for receiving the load is fastened to the load carrier, and at least three positioning cables and at least three suspension devices, each suspension device has at least one positioning cable winch for winding and unwinding one of the positioning cables. The load carrier is suspended from the suspension devices by the positioning cables. The load carrier and the load receiving device fastened thereto are relocatable by activating the positioning cable winches, and the load carrier has at least one multi-cable suspension to which at least two of the positioning cables are connected via cable connectors. Each of the cable connectors is mounted on the multi-cable suspension to be pivotable about at least two pivot axes aligned to be mutually orthogonal, and all pivot axes of the cable connectors intersect in a common intersection point of this multi-cable suspension.

Load transport system for transporting a load in a working space

A cable winch arrangement () which includes at least one cable drum (), which is mounted rotatably about a drum axis (), for winding up and/or unwinding at least one cable (-), and a supporting structure (), and a spindle drive () for displacing the cable drum () relative to the supporting structure (), wherein the spindle drive () has a spindle () extending along a spindle axis (), and a cable run-off point () of the at least one cable (-), at which the cable (-) runs tangentially onto and/or out from the cable drum (), is at least substantially positionally fixed with respect to the supporting structure (), and the spindle axis () is arranged coaxially with respect to the drum axis () of the cable drum ().

Cable winch arrangement

A running wheel () for a crane (), in particular gantry crane, comprising a shaft (), a wheel rim () and a hub () connecting the shaft () to the wheel rim () for rotation therewith, at least one connection between the hub () and the shaft () and/or between the hub () and the wheel rim () having a press fit () and a first form fit established by a first stop surface (), the first form fit blocking a relative movement of the hub () in relation to the shaft () or the wheel rim () in a first direction () running parallel to an axis of rotation () of the running wheel (), wherein the connection additionally has at least one second form fit established by a second stop surface (), wherein the second form fit blocks the relative movement of the hub () in relation to the shaft () or the wheel rim () in a second direction () opposed to the first direction ().

Running wheel for a crane

A hollow profile (), in particular crane girder for a crane (), wherein the hollow profile () has a cavity () and an outer wall () bounding the cavity (), and at least one fastening element () protruding from the outer wall () for the, preferably re-releasable, fastening of at least one add-on part () to the hollow profile (), wherein the outer wall () has at least one passage opening (), which opens into the cavity (), for the fastening element (), and an intermediate space between that portion () of the outer wall () which bounds the passage opening () and the fastening element () which is guided through the passage opening () is sealed with a sealing compound ().

Hollow profile

Crane girder () for a crane (), wherein the crane girder () includes a hollow profile () having an outer wall () enclosing a cavity () and extends longitudinally, and the outer wall () of the crane girder (), as seen in a cross-section through the crane girder (), has a shape which bulges outwards at least in some regions in order to reduce aerodynamic drag, wherein the outer wall (), as seen in the cross-section through the crane girder (), has two sections () facing one another with an outwards bulging shape, which are joined together by two straight wall sections () of the outer wall (), these straight wall sections face one another, and the crane girder () has at least one running surface () for at least one running wheel () of a trolley () of a lifting tool of the crane (), wherein the sections () facing one another with an outwards bulging shape point upwards and downwards in an operating position of the crane girder and the straight wall sections () delimit the crane girder () on the sides.
