Abstract: in this paper, the design and analysis of the swing arm type elevating work platform, used in the aerial work equipment maintenance, repair and installation work belongs to a kind of small, can play a special purpose crane on special occasions. The device has a small size retraction, lifting capacity, work range degree higher characteristic. And it is very suitable for operation space which is narrow, in the strict size of the working environment has the very strong use value. Aiming at special working space and technical requirements, this paper first puts forward three kinds of solution, and the characteristics of each method are introduced in detail, by paring the advantages and disadvantages of each package, determines the final plan -- multistage scissors mechanism lifter. On the basis of overall scheme, carried on the detailed structural design. The lift posed of four sub modules, respectively for the swing arm mechanism, scissors mechanism, slewing mechanism, and the walking car. This paper expounds the design principle of each module in detail, organization characteristics, operating mode and according to the power and the choice of the motor. In order to make a design more reliable and reasonable, also check calculation of ponents.
