Construction building hoist

The invention discloses a construction building hoist. The construction building hoist is formed by building an elevating platform surrounded by a plurality of small platforms end to end around a columnar building, wherein a plurality of radial sliding chutes are formed below the elevating platform; supports capable of radially sliding in the sliding chutes are mounted in the sliding chutes; driving wheels and driven wheels are mounted on the supports; the driving wheels between the adjacent supports are in transmission through a transmission mechanism and driven by a motor arranged below in the evaluating platform through a transmission gear; the motor comprises a brake device. The building hoist is simple in structure, high in safety performance, convenient to operate and maintain, capable of greatly improving the working efficiency, and low in cost, can be fit for various terrains, and uses the clean energy and the electric energy, so that the environment protection performance is good.
