Abstract

The utility model relates to a crane which is mainly used for conveying articles during the building decoration. A telescopic moveable upright post is a support frame, and the outside of the moveable upright post is sheathed with a moveable sleeve which can revolve around the moveable upright post in axial direction. When the utility model is used, the crane is erected at an appropriate position of a windowsill or a balcony of the building; an adjusting column is rotated to cause an upper top plate and a lower bottom plate of the moveable upright post to respectively abut on a ceiling, a floor or an upper and a lower window frames, and thus the crane is fixed; a steel cable with an adjustable length, which is used for connecting a lifting hole and the front end of a lifting rod, is regulated to control the lifting rod to achieve the proper extended length and the angle; a single-phase alternating current motor is driven to drive a steal cable drum to rotate in order to tightly wind or loosen the steal cable; the steal cable drives a lifting hook to move up and down so as to lift or lower the articles. When the articles are lifted to a proper height, the power supply of the single-phase alternating current motor is cut off to stop the single-phase alternating current motor working; the moveable sleeve is rotated to drive the lifting rod to put the articles into a room.

Description

A kind of hoisting crane

Technical field
