Manual brake disengaging device for emergency descents: The manual
disengaging device for emergency descents consists in a threaded bar
which causes the approaching of the anchor to the electromagnet and
therefore the loosening of the brake. The manual descent must be
carried out only in case of a power supply current failure, following the
procedure described in paragraph
•
Emergency manual descent.
•
Lockable main cut-out switch:
The main cut-out switch is lockable in order to
allow the locking of the machine at the end of a working shift. The key must be kept
by authorized personnel (in charge of the
building site).
