Abstract: For problems of existing the current installation method to bench-type equipment of distribution network such as poor safety,high cost and large limitations,a new type of crane suitable for the installation to bench-type equipment of the distribution network was designed. The new crane frame adopted a stable plug-in tripod structure,the main body was fixed by welding with miniature electric hoist and hoop,the rest of the crane used step-by-step design of using mathematical modeling,angle steel bearing capacity analysis,compressive bearing test and so on,combined with actual application,achieve the effect such as not being restricted by terrain conditions,low cost,convenient to carry,simple to use and so on. After the complete assembly,through actual lifting on site tested the whole machine,the results showed that the lifting process of this crane was safe,stable and orderly,conform to the actual use standard on site,while it had been promoted and applied in the field of distribution network construction and transformation.
