The present invention relates to a tower crane, in particular a revolving tower crane, comprising a crane tower composed of a plurality of tower pieces, a main boom arranged at the tower tip, and a counter-boom, wherein at least one main hoist rope is guided over the main boom to take up the load and at least one counter-boom hoist rope is guided over the counter-boom to take up balance weight.

A crane may comprise a mast that includes a base end and a top end located opposite the base end, at least one support beam fixedly coupled to the mast adjacent the top end of the mast, a first runway beam fixedly coupled to the at least one support beam, and a second runway beam spaced from the first runway beam. In some embodiments, the first runway beam defines a first end and a second end, and the mast is located closer to the first end than the second end. The crane may also comprise a bridge movably coupled to the first runway beam and the second runway beam, a trolley movably coupled to the bridge, and a hoist coupled to the trolley. In some embodiments, the crane only comprises one mast.

An elevator cage is used in an energy storage and delivery system to move blocks between a lower elevation of a tower and a higher elevation of a tower to store energy and to move blocks between a higher elevation of the tower and a lower elevation of the tower under force of gravity to generate electricity. The elevator cage removably receives a block thereon and supports the block on at least three sides.

A lift system for performing operations on a structure includes a base and rack assembly mounted on the base. The rack assembly includes at least two legs. A carriage is engaged with the rack assembly, and is configured to travel vertically along the legs of the rack assembly. A crane is configured for transverse movement on the carriage. In some implementations, the base is moved under self-propulsion. In some implementations, the base includes a leveling assembly that is operable to adjust an orientation of the rack assembly with respect to the structure.

The invention relates to a method for recognising a setup state of a crane in which a crane setup state input manually into the crane controller is compared with the actual current setup state, comprising the steps of determining the target position of at least one target crane element installed on the crane on the basis of a crane setup state stored in the crane controller and at least one crane sensor value, transmitting the one or more pieces of target position data to a mobile flying device, moving the flying device into a region in the immediate vicinity of the target position of the target crane element and detecting and identifying a current crane element located there using a detection means, and identifying the current crane element detected in the detection region and establishing whether the detected crane element corresponds to the target crane element.

A fall protection device configured to retain and prevent the fall of a connecting pin used for an end-to-end assembly of two frame elements of a structure, the fall protection device includes a clamping collar having at least one internal groove, configurable between an open position capable of authorizing the insertion of an enlarged head of the connecting pin, and at least one closed position capable of locking the enlarged head inside the internal groove. The device further includes a lock cooperating with the clamping collar to lock the clamping collar in the closed position and a mooring link anchored on the clamping collar to moor the device on a fixed element.

A crane may comprise a mast that includes a base end and a top end located opposite the base end, at least one support beam fixedly coupled to the mast adjacent the top end of the mast, a first runway beam fixedly coupled to the at least one support beam, and a second runway beam spaced from the first runway beam. In some embodiments, the first runway beam defines a first end and a second end, and the mast is located closer to the first end than the second end. The crane may also comprise a bridge movably coupled to the first runway beam and the second runway beam, a trolley movably coupled to the bridge, and a hoist coupled to the trolley. In some embodiments, the crane only comprises one mast.
