<p>The present invention belongs to the field of the construction industry and relates to a novel system for erecting and positioning construction components and materials, and it consists of a collapsible structure that combines the qualities of scaffolding, gantry crane and travelling crane and also moves by means of rolling devices to the next work site without being dismantled. The entire structure provides total freedom of manoeuvre within the space delimited by the site, making each and every one of the articles involved in a construction fully available. Said articles are suspended from the actual structure, which therefore optimizes manpower performance and prevents worker fatigue. In addition, if necessary, work can take place in a covered space, protected from inclement weather.</p> |
