Abstract
A gallery for use as a means for supporting workmen and/or materials at levels above the ground has a platform, a balustrade extending upwardly from one longitudinal marginal portion of the platform, and a gate which is secured to the balustrade by one or more aligned hinges having a pintle defining for the gate a vertical pivot axis for movement between an open position in which one side of the gate is adjacent to the inner side of the balustrade and a closed position in which the lower portion of the gate abuts against a stop mounted on the platform and being spaced apart from the balustrade. In order to enable the gate to pivot beyond such closed position, the hinge or hinges allow the gate to be lifted to a level above the stop so that it can bypass the stop and move to a second open position in which its other side is adjacent to the inner side of the balustrade. The stop can define a vertical recess which can receive a portion of the gate so that the latter is locked in the closed position. A bolt, hook or the like can be provided to secure the gate in the closed position or in the selected open position.
