LW 465R/480R/WT 600 LIFTING TOWERS
INSTALLATION AND USER MANUAL 1
LW 465R and LW 480R are the new lifter towers of WORK® One serial of towers produced in steel
and entirely safe. They are able to lift loads all straight from the soil up to a height of 8 m (LW 480 R)
or 6,5 m (LW 465 R), without any effort for the user. These towers have a different number of
profiles with the goal of reaching the maximum elevation (5 sections for LW480 R and 4 for
LW465R). It special design reaches a total reliability due to its multiple security systems, locking
system or independent blocking pins for each section.
As usual in WORK® products, all the components have been oversized with the goal of achieving a
superior security:

IMPORTANT
Taking adxperience and good sucess
obtained in effectiveness, security and
endurance with the system used in our
Series 400 Lifting towers, we have
develop WT 600 for the elevation of
Line Array systems.
Its innovate design in the profiles section,
allowsto this lifting tower, the elevation and
supportof heavy loads (up to 350 Kg) to a
maximum height of 6 m., Making them very
adecuate for big complexity shows.
The ground strenthening system has been
conscientiously studied, providing to the
tower of a sujection legs of high length
with inclinated stabilizers.
To carry on system designed for Line
Array support has been reinforced
taking in account the exerted force, so
the thickness of metallic walls and
sujections rings, is superior, incroporating
also an angle finishing that allows to
give out the load over the whole
support in equitable way.

2º These towers have a light inclination (2º) over the vertical axis in
order to displace the gravity centre to the opposite side of the
load, getting a better balance with the coupled load.
For the transport, LW 465R and
LW 480R incorporate a folded wheel

FASTENER SYSTEM
This system uses a profiles specially designed in order to bear
heavy loads.The wide of these profiles and the thickness of their
walls ensures a big firmness of the set. These profiles incorporate
a rail with a serie of fixation holes where the security bolt are
located.
These holes have the sufficient size in order the bolts could be
introduced quickly, providing the folding speed of the tower.

The pulley system (upper and lower on each profile) entrusts to transmit the generated strain

design in order to handle the cable, enclosing the whole system in a compact set.

The fastener system operates in following way:
We turn clockwise the winch that thighten the cable and thanks
to the pulley system, the more outer profile is elevated.
ALL SECURITY BOLTS MUST BE IN BLOCK POSITION,
so the elevation of the profile cause that the spring pin
of the bolt retracts, which triggers when a hole of the profile
is located in paralell with it, blocking the tower in that position.

Do not elevate the tower
without using the stabilize
legs.
Place the tower over a flat
and stable surface.
Do not install it in a place
where the use over the
stabilize leg would not
be enough to reach a
perfect balance.
The two largest legs
must be placed in the
frontal tower side and the
shortest ones at both
winch sides.

For outdoor installations
ensure the tower with
security tights to ground.
NEVER fix them to surfaces
with oscillations like structures,
etc.
SAFETY RULES
BANNER
Do not use the tower
like support for banners
or decorates support. With
heavy wind, these elements
could act as “sail” and to
knock over the tower.
Do not use the tower
in heavy wind conditions.
Take into account that if the
exposed height and surface
is maximum, the tower stability
is reduced.

The load must be firmly placed
over the support the nearest
possible gravity center of the
tower, in order to facilitate its
balance.
Do not overload the tower beyond
the max. weight recommended in
the manufacturer specifications.
SAFETY RULES
?
In the moment you elevate the tower,
check that it does not take contact
with elements or objects which with
the tower could hit or come off.
Be aware specially with the electrical
conductions, due to the towers are
not electrically isolated, it can
represent a serious electric shock
danger.
Do not stay down to the tower
after the tower elevation nor
elevation or folding process.
This tower is not designed
to elevate persons. Do not
use it for a different purpose

PLACING THE LOAD
Once the tower is fixed and balanced over the ground, you can proceed to locate the load
over the incorporated support.
NOTE: THE HOLDER DESIGN ALLOWS THE LOAD ELEVATION FROM
30 CM OF THE GROUND, PROVIDING ITS HANDLING.
For this purpose, remove the external bolt located on each arm in order to make the
extraction. This support must be placed in horizontal position and the pin bolt must
be fixed again.

INSTALLATION AND USER MANUAL 10
Place the tower over a flat and stable surface to install the tower, discarding its use over
rolling platforms or surfaces which would be able to bear as much its own weight as coupled
load.
The installation area must be free of debris, stone, etc. that reduce the firmness of the tower at
ground.
Moreover the tower must no be placed near elemenst which can obstruct the vertical folding
process like balconies, cornices, etc.
Be aware specially with the proximity of electric cables which the tower could take or crimp
them. Consider that the tower is not electrically isolated, so, it can be load with electricity
and to constituate a serious electric shock risk.
The tower disposes of two sets of legs with different length in order to settle the tower
Remove them for the transport support in order to insert them.

PLACING THE LOAD
Place the load over the support, taking into account the security recomendations indicated in
the HANDLING PRECAUTIONS section, like this:
- To assure stability and balance of the lifting tower.
- To place the load the nearest possible to the gravity center of the tower in order to avoid the
“ lever effect”.
- Do not overpass the weight recommended in the manufacturer specifications.
NOTE: In order to make easy the load descent process and tower folded, the
minimum load coupled on the tower must not be smallest than 30 Kg.
- To assure and fix the load in order to avoid load movements.
