<p>A raisable work platform comprises a horizontal support plane (20) which is predisposed to support a vertical load and is associable to a telescopic lift arm (30). The device comprises: a first joint element (2), solidly constrained to the support plane (20); a second joint element (3), associable to a free end of the telescopic lift arm (30). Means for connecting, predisposed to connect the first joint element (2) to the second joint element (3), enable the joint elements (2, 3) to translate only relatively. Means for supporting (5), interpositioned between the first joint element (2) and the second joint element (3), are predisposed for supporting the total vertical load of the platform, constituted by the weight of the platform itself and the load borne thereon, through elastic means (12). Means for measuring are associated to the means for supporting (5), which means for measuring signal a reaching of a predetermined deformation of the elastic means.</p> |
