Description

Extendable and variable gondola {Extendable and variable gondola}

The present invention relates to an expandable gondola. More specifically, the gondola cage can be expanded in the longitudinal direction according to the shape of the building, etc., and the position of the wire can be easily changed without restricting the movement of the worker, so that the entire floor of the building can be expanded. This relates to an expandable gondola that shortens construction time and improves work efficiency because work can be done without moving the gondola cage.

In general, a gondola is a device for elevating buildings or bridges to a desired location for construction or maintenance work. It includes a fixture fixed to a railing on the roof of a building, and an arm connected to one side of the fixture and extending to the outside of the building. and a pair of wires, one end of which is fixed to the support frame and extending downwardly along the outer wall of the building via the arm and spaced apart from each other, and this pair of wires are coupled to both ends, and the wires can be unwound or wound inside. It includes a cage equipped with a winch, and is configured to lift the cage to a desired location in the building by operating the winch to unwind or wind the wire.

However, in conventional gondolas, the horizontal length of the cage is already standardized, so when the horizontal length of the building is relatively longer than the horizontal length of the cage at the site, workers riding in the cage perform exterior construction or maintenance for one entire floor of the building. There is a problem that repair work cannot be completed in one go. Accordingly, in order to complete exterior construction or maintenance work on an entire floor, the gondola must be moved horizontally several times and the entire gondola, including the fixture installed on the rooftop, must be moved as described above. The horizontal movement of the gondola is cumbersome and time-consuming, and work efficiency is reduced because work on one floor is interrupted rather than continuous. In addition, there is a problem that work efficiency is reduced and work time is delayed, resulting in a long overall construction period.
