Cantilever hoister with vertical concrete columns for building

Abstract

A cantilever hoister using the concrete column of building as its supporting vertical frame is composed of a rotary table consisting of turn-table, rotary wheel, drive and driven gears, guide roller and base frame, a rotation mechanism consisting of motor and speed reducer, a hoisting unit consisting of rotary prop, steel wire cable, splitted winding drum and lock of steel wire cable, a hoisting arm and a balance arm set up on the rotation mechanism.

Description

Technical field [0001] The invention relates to a crane, in particular to a floor concrete column cantilever crane. Background technique [0002] At present, most of the known building constructions use tower cranes or hoists with door-shaped support frames as lifting equipment, which not only takes up the construction site, but also builds a special concrete base for the high-rise brackets that are raised on the ground to fix these equipment. Once the building is built, the base is abandoned, which not only causes waste but also increases the construction cost. Moreover, this large hoisting equipment is not suitable for use in places where the density of some buildings is high and the space has line obstacles. [0003] Chinese patent 93231831.2 discloses a jib crane with a fixed column, which consists of a fixed column, a rotating support, a hoisting mechanism, a jib, a rotating mechanism, a hook assembly, and a horizontal traveling mechanism. The main feature is the horizo...

[0002] At present, most of the known building constructions use tower cranes or hoists with door-shaped support frames as lifting equipment, which not only takes up the construction site, but also builds a special concrete base for the high-rise brackets that are raised on the ground to fix these equipment. , once the building is built, the base will be discarded, which will not only cause waste but also increase the construction cost. Moreover, this large-scale lifting equipment is not suitable for use in some places where the building density is high and there are line obstacles in the space.
