A raisable work platform has a horizontal support plane which is predisposed to support a vertical load and is associable to a telescopic lift arm. The device includes: a first joint element, solidly constrained to the support plane; a second joint element, associable to a free end of the telescopic lift arm. Members for connecting, predisposed to connect the first joint element to the second joint element, enable the joint elements to translate only relatively. Members for supporting, interpositioned between the first joint element and the second joint element, 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 members. Elements for measuring are associated to the members for supporting, which measuring elements signal a reaching of a predetermined deformation of the elastic members.
