A balanced cantilevered feeding apparatus for coupling with a jib, and a complementary method for its operation, configured to facilitate depositing and removing of a load through an opening in a building. The apparatus includes two spaced apart upright hoisting assemblies disposed on the jib, and a fly beam hoisted, balanced, and selectively positioned along a lateral axis by the two hoisting assemblies. A load securing member is mounted on a cantilevered extension portion of the fly beam, wherein the member extends beyond one of the two hoisting assemblies toward the building, and a counterweight is connected to the fly beam in the vicinity of another of the two hoisting assemblies.

A luffing crane which includes a luffing jib pivotable about a pivot axis in a front side of the crane and a tip-over balance that includes at least a movable counterweight. The movable counterweight is configured to move toward the front side of the crane when the jib pivots upwards toward a stalling posture, and further configured to move away from the front side of the crane when the jib pivots downwards to assume a forwardly headed horizontal position, so as to prevent the crane from tipping over when operating. The movable counterweight may move beyond the jib pivot axis such that when the luffing jib is nearing or at complete stall, the movable counterweight is positioned to the front of the jib pivot axis. The tip-over balance may further include a static counterweight located to the rear of the jib pivot axis, to provide further stabilization.
B66C 23/76 - Counterweights or supports for balancing lifting couples separate from jib and movable to take account of variations of load or of variations of length of jib
B66C 23/72 - Counterweights or supports for balancing lifting couples

Modular, adaptable and foldable apparatus for a climbing crane
Crane-support apparatus for mounting a tower crane onto a side of a high-rise building under construction, enabling ascending of the tower crane according to the upwards progression of the building construction, including a chassis configured to support a climbing frame of the tower crane mast, and at least one reinforcement element. A distal end of the chassis is hingedly attached to the distal end of the reinforcement element. In a deployed, support mode, the chassis is aligned in a horizontal position, and the reinforcement element is aligned in a slanted position. In a folded, mobilization mode, the chassis and the reinforcement element are configured to be pulled by at least one lifting cable at the distal end of the chassis and the reinforcement element with the chassis and the reinforcement element hingedly folded and aligned in vertical positions. A method for using the apparatus in both modes is also provided.
