Abstract

The invention discloses a small multi-purpose crane, comprising a hoisting arm, a rotary frame, a flexible drive device, a lifting drive device, a sleeve and a bracket, wherein a support platform is arranged above the rotary frame, two sides of the rotary frame are provided with sliding channels, and a centre column is arranged below the rotary frame in a welding way. The centre column penetrates through the sleeve, and the sleeve is connected with the bracket. The hoisting arm comprises a pair of parallel sliding rods and cross beams which are welded at the front sides and the rear sides of the sliding rods. The sliding rods of the hoisting arm are sleeved in the sliding channels at the two sides of the rotary frame. The flexible drive device comprises a motor No.1, a speed reducer No.1, a driving gear No.1, a driven gear No.1, a screw lead, a nut and a hand wheel. The lifting drive device comprises a motor No.2, a speed reducer No.2, and a winch. The winch is formed by coaxially connecting two winding drums, a steel wire rope is wound on each winding drum, and the steel wire rope is connected with a hang hook after bypassing a fixed pulley. The small multi-purpose crane is flexible and convenient to use. The hoisting arm is flexible, and the turning radius is small, so that the hoisting arm can be applied indoors or outdoors and can be used for hoisting medium-and-small sized objects.

Description

technical field [0001] The invention relates to lifting equipment, in particular to a small and light lifting equipment. Background technique [0002] The hoisting equipment in the prior art is mainly used in engineering, such as a crane, which is too large in size, inconvenient to operate, not flexible enough, has a large turning radius of the boom, and has large limitations in use. It is not suitable for indoor use, nor is it suitable for Some small and medium-sized articles are hoisted and carried outdoors, so it is urgent to develop a multi-purpose small crane. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide a multi-purpose small crane, which is flexible, easy to operate, telescopic boom, small turning radius, suitable for indoor and outdoor use, lifting some medium and small items. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] ...
