Machine slide carriages are generally used to support cargo. Machine slide carriages can run on overhead rails. There are many machine slide carriages. For example, to avoid excessive deflection of the chain, it can be divided into heavy machine slide carriages. An empty machine slide carriage.

There are two types of cantilevered scaffolds, one of which is one pick per floor. Generally speaking, the bottom of the pole can be placed on the floor, beam or wall and other building parts. After being inclined outward and fixed, it is erected on the upper part. The horizontal bar and the scaffolding board form the construction layer, and the construction is one layer high. After the upper layer is transferred, the scaffold is re-erected to provide the construction of the upper layer;

The other type is a multi-layer cantilever, which divides the full-height scaffold into several sections, each of which has a erection height not exceeding 20m. Using cantilever beams or cantilever frames as the base for scaffolding Scaffolding over 50m can be erected, and the cantilevered scaffolding facade must be fully covered with scissors.
