Device for, for example, a beam (2) extending along a compression area or another construction element in the construction, to allow indication of beam movements etc.The device is appropriate for work in difficult conditions and allows for effective indication of movements for the beam in question.An activating device (6) essentially running the length of the beam is borne in or near the beam (2). At least one part (6a) of the activating device is connected to the beam (2) as the activating device is attachable to the beam (2) via a movement transfer piece (11) for transfer of beam movement to said activating device (6), which is positioned to be able to indicate beam movements.<IMAGE> |
