Rectangular floor for scaffolding, has main and auxiliary hooks selectively activated by gripping with bar, where passage of active position of auxiliary hooks to active position of main hooks is carried out by simple sliding of floor

摘要

The floor (1) has main hooks (2, 2') holding ladder bars (9-12) in horizontal position (PH) of the floor. Auxiliary hooks (3, 3') co-operate with the main hooks to hook the floor in an inclined position in which the bars are vertically spaced from a step of a ladder (21) to another ladder (22). The hooks are arranged in extension from one another at/near ends (1A, 1B) of the floor. The hooks are selectively activated by gripping with one of the bars. Passage of the active position of the auxiliary hooks to the active position of the main hooks is carried out by simple sliding of the floor.
