Abstract: Aerial crane work is flexible, convenient, practical, safe, reliable, and suitable for a variety of complex construction environment. Thus, it is an integral part of modern industrial construction. However, most of the existing aerial working platforms can only move in the vertical direction, and their efficiency is greatly limited. To complete an overhead operation, the basket needs to be adjusted in position several times in order to cover the entire working area. It consumes high energy, and takes a long time. Aiming at this problem, a two-wire vertical space moving system is designed and two-wire vertical working basket which can be moved horizontally is put forward. The distance between the two ropes and the two points on the roof is calculated using trigonometric function, which is transformed into the rotation angle of the hoist, enabling the basket to move flexibly in the vertical space, both horizontally and vertically. And the two-dimensional movement of the basket in the vertical space is realized through theoretical calculation and simulation. The reliability of the algorithm and the rationality of the device are tested. The experimental results show that the device has the characteristics of low cost, stable and efficient greatly improving work efficiency while guaranteeing the safety factor.
