Security system ALS / ILS
The HDT-8 incorporates the patented se-
curity system ALS (Automatic Lock Secu-
rity). This VMB red trigger system automa-
tically blocks the tower in the position it is
left in. Each section of lift has an ALS that
blocks the section in the unlikely event of
the cable breaking. For a more complete
security the lifting carriage incorporates
the ILS system (Inertial Lock Security)
PRO LIFTS S.L.
4.7 - Elevation:
Turn the winch crank clockwise (N
the carriage and profiles. The ALS sys-
tems enable the lift to rise and automati-
cally block the carriage and profiles whilst
rising ensuring that it will never fall. This
enables the cable to be without any force
and means it is only used for the elevation
and descent of the lift. The SRS (Sequen-
ce-Retainer-System) will also ensure that
the profiles rise in sequence, one after the
other.
