摘要

The device has multiple supports, which are radially hooked to a cable that surrounds the chimney. Each support has a stringer with an upper clamp, which hooks to the cable and inferior roller of rolling support in the chimney. A carrier beam originates from the lower part of the crossbeam. The carrier beam prolongs in a prop with a lower flap of girth step. Telescopic embedded braces have a rail to support the props. Each support has a beam retainer, which is adaptable in height. Few sockets with slippery anti-rotating plates protect the cable. The device has another independent cable.
