Application of Multi-Dimensional Wire Cranes in Construction

In this paper, we propose a new type of installation, “multi-dimensional wire crane”, which can be used for construction of buildings and their façade maintenance. By using wires, the structure of installation becomes simple, and it is easy to install. To prove the effectiveness of the idea, we developed a prototype of 2-dimensional wire crane and a prototype of 3-dimensional wire crane. This paper describes the structure and the control algorithm of 2-dimensional wire crane. The experiment results are also presented here. The structure of 3-dimensional wire crane is also described in this paper.
