摘要

A structural arrangement of self-elevating sections, mobile in character, which is characterized by the fact of comprising a seriº variable in number of partial frameworks -sections- generally equal to each other but progressively smaller, which are susceptible to stay in each other and deploying telescopically in the sense of its height, provided that the first section or base frame, has attached manual or mechanical means to originate the deployment of said sections in a simultaneous manner, so that the maximum deployment position is achieved in all the sections at the same time.
