Description

Highly available worktable with adjustable angle

The present invention relates to a high-altitude work platform that can be easily operated even from a high place, in particular, when the installation of the exterior material, such as a chassis in a building with an inclined outer wall, the glass window adsorption mechanism is installed on the front and easy to work The present invention relates to an expensive workbench with an adsorption mechanism capable of moving the plate forward and backward and adjusting the inclination angle.

In general, an expensive workbench or a high place workbench is a machine made to facilitate work in a high place that is not directly touched by a person such as an exterior wall of a building, a window, or a ceiling inside a building. The equipment can be operated from above. Hereinafter, the term "highly available work bench" will be referred to collectively.

The high-cost workbench may be classified into a straight-type high-cost workbench, a refractive high-cost workbench, a vertical high-cost workbench, and the like according to its use and location.

First, the straight-type high-cost workbench is fixed to the end of the crane moving in a straight line, such as an elevated ladder truck, there is an advantage that the operation function is simple and convenient to use. The Articulated High Platform is suitable for use in complex areas or in obstructive areas where cranes have multiple nodes, which would prevent the Straight High Platform from working. In addition, the vertical high-cost work bench is vertically moved vertically by a bellows-shaped crane, and is widely used in a narrow indoor space or a complicated workplace.

By the way, in the conventional high-cost workbench configured as described above, when the window installation work on the outer wall of the building, a number of workers have to install the window directly, there was a lot of inefficient problems that require a lot of work time and waste time. Moreover, there was a greater difficulty in installing glass windows on sloped areas that widened as the outer wall of the building rose upwards.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to install a glass window adsorption mechanism on the front surface to facilitate the work when the glass window installation work in a building in which the outer wall of the building is inclined, and the work board can be moved back and forth In addition, the present invention provides a high-cost work bench equipped with a window adsorption mechanism capable of adjusting the tilt angle.
