A crane lifting device, and method for raising and/or lowering a load-handling element of a crane lifting device, allows for operating the lifting device with a first velocity or with a second velocity greater than the first velocity, by means of a control unit. To achieve a reduction in impulses while raising the load-handling element, and to achieve an extended service life of the supporting means, an inclination sensor is used to determine an inclination angle of the load-handling element and/or a state sensor is used to determine a free or occupied state of the load-handling element. An evaluating unit interacts with the control unit in such a way that, depending on the determined inclination angle and/or the determined free or occupied state, the evaluation unit prevents or permits operation of the lifting device with the second velocity by means of the control unit.

An installation jib for a girder beam installation and removal system includes a main body having a first end and a second, opposite end, the main body extending along a longitudinal axis between the first end and the second end. The installation jib further includes a first sub-frame element coupled to the main body, a first roller coupled to the first sub-frame element, a second sub-frame element coupled to the main body, and a second roller coupled to the second sub-frame element. The first sub-frame element and the second sub-frame element are spaced longitudinally apart from one another, and the first roller and the second roller each are configured to rotate about an axis that is parallel to the longitudinal axis.

An overhead travelling crane having a horizontally extending crane girder, which can be displaced in a railbound manner along a craneway, and having a crane trolley, which can be displaced along the crane girder and carries a lifting gear for raising and lowering a load. The lifting gear has a suspension structure formed as a cable or chain and the overhead travelling crane has electric drives for movements of the overhead travelling crane. The overhead travelling crane has an energy store connected to the drives to supply the drives with energy.

Systems and methods determine locations of moving equipment in an area holding components to be moved. Moving equipment can relocate relative to the holding area to pick up components in the holding area from an origin and deliver them to a desired location or orientation. The moving equipment includes a device emitting a signal that is detectable where it hits components or other structures in a straight line or known path from the moving equipment. A human or computer can determine a position the moving equipment in the holding area from such signals. Devices can operate with visible light generators including LEDs, incandescent or fluorescent bulbs, and lasers and including lenses or reflectors to shape the light into detectable and high fidelity configurations. Automation components including a hardware processor, controller, and detector can operate moving equipment based on detected light, without human interaction or as a verification in human operations.
