Description

Movable crane for mounting oversized building blocks Technical Field The invention relates to the technical field of building hoisting equipment, and particularly provides a movable crane for mounting oversized building blocks. Background The invention relates to a movable crane, in particular to a vertical transportation crane, which has the advantages of flexibility, portability, convenient carrying, convenient operation, low cost, suitability for narrow space hoisting construction and the like, is widely applied to building construction, is usually placed on a floor close to the edge of a window in building construction, is generally pressed by a balancing weight or a heavy object and the like for ensuring safe hoisting operation, is anchored and tensioned with a floor main structure by a steel wire rope at the rear end of the crane body for multiple safety protection, avoids the risks of integral overturning, forward sliding falling and the like, improves the hoisting safety of the crane, and is a fixed cantilever structure which is non-rotatable for furthest ensuring the hoisting safety and stability, prevents the hoisted object from shaking and collision in the hoisting process, and is used for only executing pure vertical hoisting, and has the following obvious limitations although the safety and reliability are higher. 1. The crane can only carry out pure vertical hoisting or can only carry out small-amplitude translation in the horizontal direction, when carrying out the layer-by-layer hoisting construction of a top building, for example, glass curtain wall installation is carried out, the crane can only carry out block-by-block vertical installation aiming at the glass curtain wall in a single vertical direction, if the crane position is required to be regulated when the glass curtain wall at different positions in the horizontal direction of a floor is hoisted, the crane is required to be moved, the crane posture is required to be readjusted, re-anchoring is required, time and labor are wasted during frequent movement, the construction period is delayed, and the risk of improper fixation of the crane is also increased. 2.
