Abstract
A device for installing at least one roller in a liquid zinc bath in a galvanizing line used for the galvanization of a continuously-moving steel strip has a beam to which a first pair of arms is attached. The first pair of arms bears a bottom roller. The bottom roller is intended to be submerged in the liquid zinc bath towards a bottom roller operation position, relative to the naturally submerged position of the bottom roller, by way of a movement provided together with a first cylindrical bearing attached to each of the two ends of the beam and supporting the first pair of arms. A second cylindrical bearing is attached to each of the two ends of the beam and separate from the first cylindrical bearing on the same beam end section. A push device interacts with at least one of the first and second cylindrical bearings such that, in the operation position, the first and second cylindrical bearings are maintained in a single predetermined plane and such that the first cylindrical bearing is disposed under the second cylindrical bearing at a minimum supporting height along a vertical plane.
