Description

Equipment for driving gondola

The present invention relates to a gondola running facility, and more particularly, to a gondola running facility capable of not only up and down but also left and right running (crossing).

When building a ship, a gondola is mobilized for work at height.

High-place work such as painting, welding, and finishing work is carried out on the hull shell plate through a gondola that travels up and down in the hoisting and hoisting method.

Gondolas are usually applied to vertical sections of ships. The vertical section is the portion of the hull that falls vertically from the top to the bottom as seen from the sides except for the bow and stern of the ship. In the curved section that appears on the bow or stern of a ship, a high-altitude working vehicle is usually applied.

There is a need for left and right running (crossing) of a gondola that is fixedly installed at a specific location, unlike a high-place work vehicle.

This is because the overall length of the ship is very large, and moving only up and down from a fixed installation position greatly limits the working radius of the operator. There is a demand from workers who want to work by moving the gondola left and right a little more. It slows down the work speed and forcibly widens the left and right working radius, which causes a risk of safety accidents.

The above problems can be solved by installing a large number of gondolas at once, but it requires the expansion of a large number of gondola equipment and manpower.

In particular, in the installation process of the gondola, the installation of the support (such as hook type, anchor type, welding type, etc.) Reinstalling the support in a new location consumes a lot of resources.

The inventor of the present invention has completed the present invention after long research and trial and error in order to solve various problems that occur in enabling the gondola to travel not only up and down, but also left and right.
