Quick Operation Guide
CAUTION
When two towers are used to elevate a bridge
or many towers to elevate a structure of any
type, it is almost impossible that two or more
people co-ordinate the winches elevating or
lowering the loads, at exactly the same pace.
At a certain point each tower will be extended
to a height different to that of the others.
For this reason it is necessary that the
subjections of the structure account for this and
allow for these differences. With a rigid fixation
and if the level difference is significant, 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 TL-072 incorporates the patented security
system ALS (Automatic Lock Security).
This VMB red trigger system automatically
blocks the tower in the position it is left in. Each
section of chain has an ALS that blocks the
section in the unlikely event of the chain
breaking.
4.7 - Elevation:
Turn the winch crank clockwise 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.

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.
4.9 - Lowering:
Lift the load until the als lock becomes free.
Press the ALS lock (RED) in and hold it there.
Then lower section by section. Repeat the
above process for each section until all are
completely lowered. If the ALS gets locked, lift
the load slightly so the ALS lock becomes free
and lower as above.
4.10 - Transport:
For the transport of the tower is necessary to
fold the machine lowering completely all the
profiles. Once the towerlift is folded it is very
important to block the lifting carriage with its
transport support (B). Get out the legs leaving
the blockade on the triggers and put them in
their transport lodging (S). Then press the
fastening screws.
