An energy storage and delivery system includes a crane elevator cage, where the crane or elevator cage is operable to move one or more blocks from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move one or more blocks from a higher elevation to a lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The energy storage system can, for example, store electricity generated from solar power as potential energy in the stacked blocks during daytime hours when solar power is available, and can convert the potential energy in the stacked blocks into electricity during nighttime hours when solar energy is not available, and deliver the converted electricity to the electrical grid.

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.

An energy storage and delivery system includes an elevator operable to move blocks from a lower elevation to a higher elevation to store energy and from a higher elevation to a lower elevation to generate electricity. A winch assembly is movably coupled to a cable that is coupled to the elevator. The winch assembly has planetary gear assemblies, brakes that selectively engage at least a portion of the planetary gear assemblies, and a spool coupled to the cable. A drive shaft extends between a motor-generator and the winch assembly. A brake is operable so that the spool rotates to reel-in the cable to raise the elevator to move a block from a lower elevation to a higher elevation to store energy or so that the spool rotates to reel-out the cable to lower the elevator to move a block from a higher elevation to a lower elevation to generate electricity.

Provided herein is a crane tie arm assembly for connecting a crane to a structure. The assembly comprises: (i) a first arm comprising a cylindrical female end portion having a plurality of internal, elongate protuberances parallel to one another and arranged in axially extending columns; and (ii) a second arm comprising a cylindrical male end portion having a plurality of spaced external, elongate protuberances, which protuberances are arranged in axially extending columns on the external surface thereof for mating engagement with channels formed between protuberances of the female end portion. The assembly can be coupled and locked in place by sliding the male end portion axially into the female end portion and then rotating either end portion circumferentially to sufficiently to engage surfaces of the protuberances with the channels. A stop element is disposed on the female end portion or the male end portion for preventing over-elongation of the assembly.

A multi-component lattice mast section comprises a longitudinal axis, a plurality of chord elements extending along the longitudinal axis, a plurality of connection bars interconnecting in each case two adjacent chord elements, a lattice mast cross-sectional surface area with a lattice mast width and a lattice mast height, the lattice mast cross-sectional surface area being oriented perpendicular to the longitudinal axis, and at least two detachably interconnectable lattice mast assemblies, with each of the lattice mast assemblies having a lattice mast assembly width smaller than the lattice mast width and/or a lattice mast assembly height smaller than the lattice mast height, and with the connection bars being firmly connection to a chord element in a working arrangement.

An energy storage and delivery system includes a crane operable to move blocks from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move blocks from the higher elevation to the lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The blocks remain vertically spaced from each other, and a vertical distance between the lower elevation and the higher elevation of each of the blocks is the same.

A lifting and handling device includes a plurality of structural elements, a plurality of operating elements, at least one ballasting element mounted on a structural element, a central monitoring unit, and a plurality of identification components. Each structural, operating and ballasting element is coupled to an identification component, and each identification component includes a radiocommunication module having a radiocommunication range predefined in order to be able to communicate at least with one other identification component. A radiocommunication master unit is connected to the plurality of identification components and intended to receive identification information from each of the components. A method for monitoring an operation of the lifting and handling device is also provided.

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.
