The present invention relates to an eco-friendly wind power generation apparatus that can perform power generation using wind by providing the blades of a wind power generator on a jib of a tower crane, and can perform wind power generation at the optimum altitude and in the optimum direction by automatically or manually performing the lifting/lowering and swing operation of a jib even when wind speed is insufficient because wind is not blowing, or perform wind power generation using artificial wind power generated by the operation of the jib, thereby generating a lot of electricity in necessary places and supply the electricity to all industrial sectors regardless of location and environment.

The present invention relates to a lifting device for lifting and vertically, and possibly horizontally, replacing an object. The lifting device comprises a first unit (1) configured with one or more catching parts such as suction pads and a second unit (2) configured to control vertical and optionally horizontal position of the object.

The second unit (2) comprises a first attachment position and a second attachment position and the first attachment position is fixed to a vertically extending part (3) of the first unit (1); the second attachment position is fixed to a sliding member (10) of the first unit (1) by a rigid joint configured to transfer all movements induced at the second attachment position by the second unit (2) to a sliding member (10) of the first unit configured to slide between two positions along a longitudinal member (11) of the first unit.

A lifting crane having a jib and a lifting device with double reeving configured to distribute and lift a load along the jib, wherein the lifting device is reversibly configurable between two reeving configurations including a single reeving configuration with two lifting strands and a double reeving configuration with four lifting strands. The lifting device includes a reeving change system for performing a reeving change between the single reeving configuration and the double reeving configuration, and vice versa. The lifting crane further includes a system for automated determination of the reeving configured to automatically determine the reeving configuration between the single reeving configuration and the double reeving configuration.

The invention relates to a crane, in particular a rotary tower crane, comprising a crane boom, from which a load hook can be raised and lowered via a hoist cable, and an electric power supply on the load hook and/or an optionally provided trolley which can be moved on the crane boom. According to the invention, the electric power is directly generated at the location where it is required, and in the process kinetic energy present at said location is converted into power. According to the invention, the electric power supply comprises a generator which is arranged on the load hook and/or on the trolley and which can be driven by a deflecting and/or running pulley and/or a cable running around the deflecting pulley.

The invention relates to a tower crane, preferably a rotary tower crane, particularly preferably a top-slewing crane, comprising a jib and a counter-jib. The jib and/or counter-jib is hinged to the tower top and/or rotating platform by means of at least one connection point. A first connection part of the at least one connection point has a concave stop surface, and a second connection part of the connection point comprises a convex counter-stop surface, wherein the counter-stop surface of the second connection part acts on the stop surface of the first connection part by means of a pressure force in order to produce a force-fitting connection between the connection parts.

A system transports a load along a transport route, wherein the load is hoisted and kept suspended along the route. The system includes a bridge, a hoisting module hanging down from the bridge, a haul mechanism, and a resource optimizer for determining an optimal-resource consumption route, including determining respective parameters of acceleration, deceleration, and sway-restraint maneuvers. The route is segmented, wherein a respective segment safe-travel sway-span and a respective segment hand-over sway-span are predetermined. Each segment includes an initial acceleration section and a final deceleration section. The resource optimizer determines segment minimum resource consumption routes including determining respective parameters of acceleration, deceleration, and sway-restraint maneuvers, per the segment safe-travel sway-span and the segment hand-over sway-span, and combines possible minimum resource consumption routes, for selecting therefrom an optimal resource consuming route out of the possible minimum resource consuming routes. Transporting of the load is conducted pursuant to the optimal resource consumption route.

A Building Element Lift Enhancer is described. The Building Element Lift Enhancer provides for the movement and precise placement of building elements such as blocks or sheet products by one worker. The Building Element Lift Enhancer senses the force applied by a user to the building element and converts that user applied force to mechanically assisted force from the Building Element Lift Enhancer, allowing the user to precisely move and handle large, heavy or bulky building elements by direct interaction with the building element.
