It is mainly for construction workers to work up and down or for the maintenance of peripheral safety nets and high-altitude installation of components. It is usually made of bamboo, wood, steel pipes or synthetic materials. The tripod needs to be welded during the production process, and the existing welding method is mostly manual welding with a handheld electric welding gun.
