Background

The necessary traffic facilities and equipment are needed in the construction stage of various engineering construction projects to meet the requirements of personnel and materials for going to and fro from the upper working face and the lower working face, otherwise, the smooth implementation of the projects is influenced. Taking water conservancy and hydropower engineering as an example, a water retaining building is generally formed by pouring concrete in sections and layers, which means that a construction working surface is also formed by lifting each section layer by layer, and necessary traffic facilities and equipment need to be arranged.

According to the construction experience of hydraulic and hydroelectric engineering, not all the surfaces of a retaining structure are perpendicular to the horizontal plane, which is often designed in an anti-floating manner with an inclination angle, which has the following technical drawbacks:

1) the construction lifter widely used in the building engineering can only be arranged on the guide rail frame vertical to the horizontal plane, so that the construction lifter is not suitable for being used on the inclined plane of the water retaining building in the hydraulic and hydroelectric engineering;

2) although the construction elevator has great advantages in work efficiency, carrying capacity and convenience, the equipment is expensive to purchase, lease, install, use, maintain and the like, and is not suitable for projects with small project quantity, short construction period and small height difference of working surface.

For example, construction of piers in bridge construction requires the arrangement of temporary traffic facilities that are simple, easy to use, low in cost, and safe and reliable, and thus construction elevators are not suitable for being equipped on shorter piers.
