The present invention concerns a protective device 1 for protecting against falling objects at work sites, for example in tunnels, on mountains and in areas situated below such objects. The protective device 1 effectively protects workers from falling objects when carrying out work under such objects, for example in tunnels, in rock chambers, on mountains and at other sites where there is a risk of falling objects, but without impeding the work. The protective device 1 comprises a protective roof 2 which is movable relative to a work platform 3 so that a person located on the platform 3 can be protected from falling objects by the roof 2, while at the same time access upwards is permitted from the platform 3 through a work opening 6 in the roof 2. <IMAGE> |
