Abstract

PURPOSE: To prevent the danger of fall of workers by always making a gondola horizontal on the guid rail at the upper half of a tank and moving it up and down.
CONSTITUTION: The inner and outer guide rails 7a and 7b have the shape in which they move parallelly only at regular intervals in the internal and external directions of the tank 1. Since the interval dimensions of the inner guide rollers 12a and 12a' which engage with the internal and external guide rails 7a and 7b and the outer guide rollers 12b and 12b' have the preset intervals, the gondola 6 is always kept horizontal and moves up and down by winding and rewinding the rise and fall wire 16 by means of the wire winder 15. As a result, the inspection and repair on the gondola are performed without the danger of the fall of workers.
