ENGLISH
4.8 - Hold:
The tower can be left in any intermediate
position which would be necessary. Just
stop turning the handle of the winch and
leave it. The automatic brake of the winch
will block it and hold the load. Ensure that
the red ALS lock is in the last hole and
slightly release the winch handle anti-
clockwise. The ALS lock will take the pres-
sure of the load and release strain applied
on the cable.
4.9 - Lowering:
To bring the lift down you need to fi rst turn
the winch handle slightly clockwise (N1)
and at the same time pull the red ALS lock
out. (Fig.7) This releases the blocking
systems. Then turn the handle anti cloc-
kwise (N2), whilst maintaining the ALS
lock pulled out until the profi le has been
completely lowered. All red ALS locks
should be pulled out one by one whilst the
handle is turned anti clockwise and the
profi les are brought down, one by one. If
you release your fi nger from the ALS lock
it will automatically block. In this case, re-
peat the fi rst operation by turning slightly
clockwise and then anti clockwise whilst
always pulling the red ALS lock out. It is
necessary to completely lower each profi -
le before starting to lower the next. If you
pull another red ALS lock without having
completely lowered the previous profi le
the fi rst profi le will remain blocked by the
security system and you will not be able to
lower it later.
With a rigid fi xation and if the level diffe-
rence is signifi cant, the force generated
from the handle of the winch will deform
the structure and apply a lateral force to
the lifts causing them to break and block.
Security system ALS
The HDT-8 incorporates the patented
security system ALS (Automatic Lock
Security). This VMB red trigger system
automatically blocks the tower in the posi-
tion it is left in. Each section of lift has an
ALS that blocks the section in the unlikely
event of the cable breaking.
4.7 - Elevation:
Turn the winch crank clockwise (N1) to lift
the carriage a few centimeters. Release
the forks and place them in the working
position inserting the pins. Turn the crank
clockwise and the tower will lift. The ILS
and ALS enable the lift to rise and auto-
matically block the carriage and profi les
whilst rising ensuring that it will never fall.
The SRS (Sequence-RetainerSystem)
will also ensure that the profi les rise in
sequence, one after the other. Once the
system is elevated to its required height
gently turn the handle in a clockwise di-
rection. The security systems will ensu-
re that the load stays fi xed and blocked.
The red ALS locks will be blocked. This
enables the cable to be without any force
and means it is only used for the elevation
and descent of the lift.
