The tower can be used outdoor, only in
structural mode but with the loads
corresponding to mechanism mode (for security
purposes), if the wind speed is low and if it
doesn’t put the installation at risk. The
installation is always under the responsibility of
the owner.

Do not use the tower as a support of banners or
another type of decoration with strong wind that
can destabilize the tower and make it falls.

OPERATING MODES
MECHANISM MODE
This mode involves lifting the load with the help of the winch. That is, the load is placed in the tower once
leveled and placed with all its masts in transport position. Then, the load is raised by using the included
hand winch.
Figure 25
STRUCTURAL MODE
This mode involves lifting the load with the help of a manual or electric hoist. That is, the tower is used as
a structure that is all locked to the required working height. Once the tower is raised to this desired height,
the load must be raised with the hoist.

USING THE TOWER IN
STRUCTURAL MODE (WIND
CONDITION)
The towers used in the structural mode form a
column type system that can withstand higher
loads than the mechanism mode.
In order to be able to use the towers outdoors
and subjected to bursts of wind, you should
contact an engineer in the area or our technical
department to study the case
In outdoor use many factors must be taken into
account, the most important are:
- Wind gusts
- Total exposed area
- Working height
- Angle of the braces
- Weights and distance to the tower
- Rigging of all joints
- Etc …
As an operating guide, the towers involved in this
manual can be used outdoors as long as they are
in structural mode and the maximum loads are
those of the mechanism mode.
This is because the loads transmitted by the
winds are transmitted vertically from the tower
to the ground, adding an overload that depends
on several factors. This overload is added to the
maximum load of the tower.
If it is not calculated in each specific case of use,
it is possible to take as base the data contained
in the load chart (figure 100) operating the
tower as mechanism for security purposes.

PLACING THE LOAD
1. Determine the position where the load will be placed and consult the tower capacity. Never
exceed it.
2. The “X” distance between the load is taken from the carriage to the end of the horns.
3. When possible, place the load as close to the carriage as possible. This prolongs the life of the
tower.

LOAD CHART
The maximum loads supported by each tower model, for its maximum working height, can be consulted
below:
USING THE TOWER AS MECHANISM.
The tower behaves like a machine when lifting a load making use of the winch as a lifting element. In this
case all the parts of the tower behave like a mechanism that uses pulleys, cables and guides to be able to
execute the elevation of a load at a certain height.
USING THE TOWER AS STRUCTURE.
The tower behaves like a structure when all the sections are blocked in such a way that the cable is without
tension. In this case the locking system together with the profiles, base and legs act as a support column
from which loads can be hung using some support elements such as manual or electric hoists.

GROUND COMPACTION DEGREE
Surfaces such as hard ground or gravel can vary in strength depending on the relative humidity. This
relative humidity varies throughout the day, so the resistance of the ground to absorb the stress of the
tower loaded also varies. Positioning a tower in these conditions can result in the ground falling under the
tower supports, being able to cause a serious accident.
Figure 101
Detail of plates place. Support must be centered with respect to the plate.
To avoid this, it is advisable to put bases in the support, to facilitate uniform distribution on the ground,
expanding the contact surface of each support. The following table lists the minimum area of these
surfaces.

DYNSYS SYSTEM
The lifters that incorporate the DYNSYS system are named as WTS xxx DY:
- WTS 256 DY - WTS 375 DY - WTS 506 DY - WTS 905 DY - WTS 708 DY - WTS 1206 DY
EXPLANATION
DYNSYS system is a solution for the control of the maximum load in lifting systems.
DYNSYS limits the maximum load of the tower avoiding raising a higher load than the specified when the
tower is used as mechanism. For more information about the maximum load, consult the load chart.
In case of raising a load higher than the maximum, DYNSYS detects the increase in load and prevents it
from being raised, allowing only the descent of the load.
DYNSYS system works as a preventive maintenance element. In case the tower has some internal damage
and forces the system to operate in a forced manner, DYNSYS system will limit its use, preventing that the
internal components (cable, pulleys, profiles, etc. ...) may deteriorate further. If this happens, contact the
technical department or your nearest distributor.
The system allows the disassembly of the crank, thus allowing the blocking of the tower. In this way it is
avoided that personnel outside the installation can manipulate the tower by raising or lowering it. Only
the two Allen screws should be removed.
Figure 103
The system has several elements working in a coordinated manner. On the one hand, the most external
aluminum profile has a special machining to house the safety pin, and the iron carriage has the mechanics
of overload detection and a status marker.
Finally, the original handle of the winch is replaced by a specific one for the DYNSYS system.
35
USER MANUAL FOR WTS TOWERS
OPERATING
NORMAL OPERATION, WITHOUT OVERLOAD
Figure 104
Under these conditions, the tower raises the coupled load and no vertical displacement occurs in the
carriage (1) so that the inner spring (2) does not compress and the safety pin (3) does not act. The winch
handle allows the user to raise or lower the load with ease and the window of the status marker (4) shows
the color GREEN.
Figure 105
36
USER MANUAL FOR WTS TOWERS
OPERATION WITH OVERLOAD
In the event that the tower has to raise a load higher than the one marked in features, the tower would
enter overload mode. Under these conditions, the following occurs:
Figure 106
- There is a more pronounced vertical displacement in the iron carriage (1).
- The internal spring (2) shrinks due to this additional pressure.
- The safety pin (3) is released from its resting position and entered the first free hole found in the
aluminum profile, blocking the tower and preventing any attempt to raise the load.
- In the same way, the own characteristics of the exclusive DYNSYS handle prevents to force the winch.
- The status dial window (4) shows the RED color of overload.
To get out of this state of overload, it is necessary to lower the load and adjust it to the weight supported
by the tower.
To do this, pull the safety pin (3) to release it and, keeping it, turn the hand winch handle to lower the
load. Throughout this process, the spring (2), will be relaxed by reducing the pressure exerted on it and
the iron car will go back to the initial position. At the end of the descent of the load, you can release the
safety pin that will remain in its resting position.

USER MANUAL FOR WTS TOWERS
DYNAMIC OVERLAP
Thanks to the continuous development of new solutions for the lifting towers, Work Lifters has developed
and patented an innovative solution that increases the resistance of the towers and reduces their
deflection. Dynamic Overlap makes that each tower section overlaps with the previous one at different
distances, as with trees in nature. This means that all efforts are concentrated in the same way in all the
sections of the tower. Thanks to this, the tower can withstand greater efforts with less deflection.
Figure 107
38
USER MANUAL FOR WTS TOWERS
TRANSPORT
To transport the towers:
- Check that the legs are firmly attached to the tower in their transport position and cannot be
released.
- Check that the forks are securely fastened with the pins and cannot be removed.
- Check that the carriage is securely fastened with the car brake system.
- Check that all sections are blocked.
WITH FORKLIFT
To transport the towers with a mechanism type forklift, the AWS 100 accessory is necessary. Follow the
instructions of the machine operator transport manual. Consider the height of what is transported. Avoid
sudden turns and braking.
Figure 108

39
USER MANUAL FOR WTS TOWERS
WITH TRUCK OR CONTAINER
To transport the tower by truck or container always tie the tower by two points. Use ratchets not less than
1000 kg of force for the WTS 506, 256 and 375 models. Use ratchets no less than 2000 kg of force for the
WTS 905, 1206 and 708 models.
Place ratchets so that the tower cannot move by inertia in curves or sudden braking.

DGUV V17/18 NORM REGULATION. Explanation
DGUV V17/18 is a norm that regulates the stage and production elements in the entertainment industry.
Lifting equipment and rigging are part of this norm and cover structures and other technical elements.
Adopt DGUV V17/18 is totally voluntary (except in Germany) but its adoption is required by insurance
companies and indeed is becoming a norm in the industry
The application of this norm on lifter towers is vital because, in theaters, stages, etc.., are used to move
loads above artists, technical staff, etc... and in some cases, above viewers, representing a potential risk
of fall.
NORM DGUV V17/18. Fields of application
This standard is oriented in two ways:
On the one hand, lifting towers adopt designs and materials to achieve a high degree of safety in quantities
such as supported load, equilibrium, resistance to friction, etc.
Thus, WORK lifter towers DGUV V17/18 certified assure the user that they have passed strict controls
during design, choice of materials or load checks and effort.
On the other hand, in order to achieve an optimal performance with these units, it is recommended, apart
from a responsible use of the unit, (meeting basic norms such as obey the maximum load or balance), a
periodic maintenance, which must be carried out by expert technicians, checking the condition of the steel
cable and winch, the functioning of the security pins and the folding/unfolding of all sections.
All the above tests are only mandatory in those countries with specific regulations on the matter, applied
through regulations or laws. As manufacturers, we recommend passing all tests in order to prevent
damage and ensure proper operation of P.A. lift systems.
