Ch ha ap pt te er r 3 3 ELETTA®COVERING SYSTEM INSTALLATION
IMPORTANT!
Before starting the installation process, check the covering model at your disposal and examine
carefully any particular case that can occur.
3.1 Fitting the rear tensioning plate
3.1.1 Informations
The following description of the rear tensioning plate installation concerns the standard covering systems; in case of:
•covering systems with cable’s quick-release system for three-sided tipper
please follow the described installation process for the specific case (paragraph 4.1.1 ).
3.1.2 Fitting of the rear tension plate
The installation of the rear tensioning plate requires a special attention in order to avoid to create any obstacle for mobile
elements (i.e. tailgate with lateral opening system).
The best installation position for the plate is the one as close as possible to the rear edge, but at a sufficient distance for
avoiding to be an obstacle for hinges
WARNING!
A wrong positioning of the tension plate could cause damages for the covering or for the tipper body.
If in doubt, carry out mobility trials of the rear mobile elements to avoid unpleasant surprises.
•Drill four M10 threaded holes on the side corresponding to the holes on the plate, at
the distances shown in the figure above.
•Fasten the plate using the M10x35 countersunk screws supplied, making sure that
the tensioning screw is directed towards the front of the vehicle.
•If proper threading is made difficult because of the thickness of the metal or the type
of material (e.g., aluminium body), drill Ø 10.5 through holes and fasten the
countersunk screws using UNI 7473 galvanized M10 self-locking nuts.
Note:
During its working life the structure is subject to vibrations and stress; therefore, it is recommended to apply a medium or
strong threadlocker Loctite® liquid.
•Repeat now the plate fastening operation on the opposite board wall.
Note:
The proper fitting of the rear plates is of primary importance since it is binding for the positioning of all the
subsequent element.

3.4 Installation of steel cables
The covering systems of Marcolin Covering s.r.l. are supplied already preassembled. Therefore, after having placed the
covering on the tipper body, it is only necessary to pull out one by one the iron rods that keeps together the bows and to pull
the steel cable through the holes of the bow supports.
The main component that makes possible the proper covering functioning is the steel cable.
CAUTION!
During the installing activities of the steel cable, the use of suitable protective gloves is mandatory in
order to avoid any injury to hands due to a possible fraying of the steel cable mesh.
Before proceeding with the steel cable installation, it is necessary to verify the alignment between the upper driving pulley of
the gear housing and the socket through which the steel cable runs.
PAY ATTENTION!
This activity is one of the most important for the proper working of the tarpaulin.
The better the alignment, the easier the handling of the tarpaulin, in case of hand-operated version, and
the lesser the motor effort in case of electrically-operated version.
Loosen the rear tensioning plates:
•Loose the centrally arranged screw that fixes in place the guide pulley
(1).
•Undo the screw adjusting the running of the guide pulley slide (2).
•Shift the pulley towards the front part.
3.4.1 Positioning of the covering tarpaulin
The covering is supplied completely assembled with bows, feet and sliding pads.
•Remove the covering from its packing and put it on the front of the body (cab protection), properly arranging the cover’s
front and back ends.
•Pull out the iron rod from the feet bushings on the driver’s side (where the first of the two wire ropes will be placed).
3.4.2 Running of the left steel cable
The explanation begins with instructions for positioning the steel cable placed on the left side (in relation to the driving
direction) in correspondence to the driver side.
Note:
The position of the cable is the same, both for the hand operated and motorised versions. If the covering is provided
with the automatic steel cable release, follow the procedure described in paragraph 4.2
Scrupulously follow the instructions below for positioning the steel cable.

18 - Installation manual - Eletta®
•Introduce the end of the rope at the front of the drive pulley on the lateral drive
unit;
The bows that support the cover are provided with steel feet with low-set bushings to allow the passage of the rope
(see figure below). A plastic sliding pad is fixed to the bottom to allow the cover to run along the edge of the body.
•Pass the rope through the bushings on all the feet and leave 10-15 cm length of rope out of the last one.
Note:
Pay close attention while fixing the pulling bow, because a misalignment could compromise the covering workings.
Now proceed with the lower end of the steel cable:
•Lead the lower end of the wire rope to the back of the body;
•Wind the rope around the rear transmission pulley (1);
•Lead the end of the wire rope back to the drawing (2).
Note:
Ensure that the bow keeps as perpendicular as possible to the board walls for avoiding any subsequent adjustment
service.

3.4.3 Cable fastening
Now that the steel cable has been properly positioned on its path the cable fixing activities can be carried out.
CAUTION!
During the installing activities of the steel cable the use of suitable protective gloves is mandatory in
order to avoid any injury to hands due to a possible fraying of the steel cable mesh.
Note:
Before fastening the cable, check carefully wheter the covering is provided with a single or double pulling bow.
1. Insert a clamp (3) in the inner
side of the support plate of the
double pulling bow (4).
2. Take the end of the cable (1)
which comes back from the
vehicle cab side and fasten it
with the clamp (3).
3. Take the end of the cable which
comes back from the rear side
of the vehicle (pulley side) (7),
overlap the first one (1) passing
it through the inner side of the
support plate (4).
4. Fasten both ends with a clamp (5) inserted in the inner side of the plate (4). Before tightening the clamp (5), pull the
cable manually for tensioning it.
5. Loose the first fastened clamp (3) and refasten it holding both cables.
6. For greater safety, it is mandatory to fasten one additional clamp on the left (2) and right (6) of the previously fastened
ones.
WARNING!
IT IS FORBIDDEN TO use different materials than those supplied with the system.
The cables must be secured with 4 galvanized steel clamps for Ø 6 cable, placed as shown in the
figures above (i.e., 2 on each side).
WARNING!
An incorrect fastening of clamps, the lack of one or more clamps as well as a different fastening process
from the described one can compromise the tarpaulin stability on the tipper body, causing its
detachment with danger and damages to people and objects.
•After having fastened the steel cable, cut the excess lenght off, but leave about 100-150 mm usable for any necessary
adjustments.
Note:
Prior to cutting the cable, wrap the cut surface with insulating tape to prevent a possible fraying.
3.4.4 Running the right steel cable
Follow the same procedure described in par. 0on the opposite side.

3.4.5 Steel cables tightening up
After positioning the steel cables tighten them up by applying the process described for the rear guide pulleys in order to
make a proper sliding of the covering possible.
As a matter of fact, the rear guide pulleys have been developed and manufactured with the aim to allow the operator steel
cable tension adjustments.
Operating alternately on the two guide pulleys proceed as follows:
•Use a 7 Nm torque wrench to tighten the screw placed on the front side (2) of
the guide pulley.
As a consequence, the guide pulley and the slide move backwards tightening up
the steel cable.
WARNING!
The left and right-hand ropes must be given the same amount of tensioning. The drive pulley is
designed with a V-shaped groove to prevent slipping and therefore does not require excessive
tensioning.
•When the required tension is achieved block the guide pulley tightening the central screw (1);
•Repeat the operation on the opposite guide pulley.
WARNING!
During the installing activities of the steel cable the use of suitable protective gloves is mandatory in
order to avoid any injury to hands due to a possible fraying of the steel cable mesh.
IMPORTANT!
Once terminated this operation make sure that the bow is perpendicular to the side board and at
equal distance from the tailgate. If not, operate consequently on the tensioning device of the steel
cable or, if necessary, proceed to block it.
