2. 2 WORKING CAPACITY
The trailer can carry load of different type and nature compatibility with the dimension of
side and flat bed in function of barycentre of machine: The bulk don’t exceed the values
indicate in the plate fixed on trailer and in the top of this manual. Is necessary to respect
the values or risk overturning the machine.
The machine is provided with its box with specific dimension and carrying
capacity: In this situation is calculated the maximum carrying capacity
reported in table and predisposed the relative safety system.
If the trailer is equipped with another configuration, who set up the equipment
must ensure the working safety operation of machine. Officina
Metalmeccaniche Ravenna decline each responsibility at about!
2.3 USE RESTRICTIONS
The machine can not be used with other terms provided in the paragraph 2.1
Is strictly forbidden remove, camper and modify in any way the safety system
present in the machine.
2.4 SOLUTIONS ADOPTED TO PREVENT RISK

Pagina 16 di 33
RAVENNA s n c - OFFICINE METALMECCANICHE RIMORCHIO PER TRATTORE
2.4.2 AREA OF WORK
The tractor operator to use the trailer in a safe condition must remain seated in the driving
seat: any other position is not allowed since it could be dangerous: the loading, positioning,
loading and unloading can also be performed with ground operators or on the chest
In these cases, act with extreme caution! It’s still anyone FORBIDDEN rest on the floor
during transfers.
Operators should pay close attention during the loading and maintenance
operations as may be in the danger zone: should pay attention to the directions
of this manual and the warning signs of danger on the machine!
CHAPTER 3
TRANSPORT TRAILER
3.1 PRELIMINARIES
The transport of the trailer can be made by trucks, containers and / or possibly railway
wagons: You must use a vehicle of a size suited to mass and dimensions of the trailer
shown in "SPECIFICATIONS".
To work safely you need to consult the manual and its appendices before carrying out any
work on the machine
3.2 HANDLING, LOADING AND UNLOADING
The trailer is normally provided free packaging and in a horizontal position: You must use
a lifting system (forklifts, cranes, bridge cranes, ...) of adequate capacity hooking on ropes
or chains to the frame of the right dimensions and the rudder to keep it horizontal.
Before proceeding to lifting, make sure that any moving parts of the trailer are securely
locked. Lift the machine with extreme caution and put it slowly, without shock or sudden
movements, be careful not to tilt it to avoid losing stability.
The lifting and transport can be very dangerous if not done with extreme caution away so
the uninitiated, clean, clear and delimit the area transfer, to verify the integrity and
suitability of the available means, do not touch the suspended load and observe the safety
distances.
The surface on which you want to load the trailer, it must be horizontal to prevent
movement of the load. Once loaded onto the means of transport, make sure that the trailer
remains locked in its position: set the plane on which is supported by the aid of ropes or

Pagina 17 di 33
RAVENNA s n c - OFFICINE METALMECCANICHE RIMORCHIO PER TRATTORE
chains of adequate size. The ropes (or chains) must be securely fastened to the trailer and
well stretched toward the anchor point on the ground.
Once the transport, before releasing the trailer from all constraints, verifies that the status
and location of the same are such there is no danger.
Then proceed to the discharge using methods similar to those used for the load.
CHAPTER 4
USING THE TRAILER
4. 1 GENERALITY
The tractor operator must be trained in the conduct of the tractor and trailer coupled:
during working hours he is responsible for the vehicle and as such have to worry about
prohibit its use by unauthorized persons.
Before starting the machine complete, the operator must make sure it is in perfect working
order.
Any problems should be reported immediately to security managers.
The terms "forward, backward, left and right" reported in the following, refer
to an operator sitting in the driving seat.
4.2 GETTING STARTED
Before attaching the trailer to the tractor:
•Check the integrity of the side and the correct positioning of themselves and their
attachment systems.
•Check the correct insertion of the four locking pins in the union U of the body to the
frame.
•Check for oil leaks through gaskets, fittings and pipes of the hydraulic circuit control
tipping body
•Check the integrity of the flexible cable and brake levers
•Check the integrity of the rear lights
•Check for proper tire pressure.

Pagina 18 di 33
RAVENNA s n c - OFFICINE METALMECCANICHE RIMORCHIO PER TRATTORE
4.3 ATTACHMENT TO A TRACTOR
First of all check that the tractor’s attachment system is approved. To attach the trailer to
the tractor, approach it with appropriate maneuvers in such a way that the coupling on the
tractor and the towing eye on the drawbar of the trailer are located very close. Perform the
operation by moving the tractor and avoiding the manual maneuvers.
Photo 2
Raise the trailer drawbar, turning the hand wheel N, the height of the hook of the tractor,
pull the coupling pin after removing the cotter pin from it, then take it with the eye of the
trailer, put the pin in eye and insert the cotter pin in the pin.
Perform the above steps carefully: on the rudder there are vertical forces that may act make
it difficult to control!
Using the hand wheel N raise from the ground as much as possible the wheel: in this way
the trailer rests on the rear axle on the one hand and on the coupling on the tractor other.
The wheel can be further raised from the ground, turning it upwards: the spring P (Photo 3)
holds it in this position: pulling the retaining pin Q the wheel, if necessary, can also be
removed from the trailer.

If the tractor there is a system of automatic hookup, verify that the connection was
successful. Pull the brake lever from its R bayonet mount on the rudder S and assemble in
the same slot on the tractor (Photo 4).
Connect finally, using the respective quick connections, the pipe of the tipping cylinder
body and the power cable of the rear lights respectively to the hydraulic system and the
electrical system of the tractor.
After attaching the trailer to the tractor, check:
•The correct functioning of the hydraulic tipping body correct operation of the braking
system
•The correct functioning of the electrical system.
4.4 LOADING TRAILER PROCEDURE
Before proceeding with the loading, turn off the tractor engine and enter the parking brake.
With the trailer horizontal as possible and using suitable lifting tackle, place the load in a
central position with respect to the body: With the trailer horizontal as possible and using
suitable lifting tackle, place the load in a central position with respect to the body: for bulk
materials do not exceed the top of the side. Fix the load with ropes or chains of adequate
size pulling them with suitable devices of the trailer.
P
Q

Pagina 20 di 33
RAVENNA s n c - OFFICINE METALMECCANICHE RIMORCHIO PER TRATTORE
In any case, always make sure that the mass of the load is less than the rated capacity
stated by the manufacturer and indicated on the label attached on the machine.
WARNING!
If the trailer is not used carefully following the instructions given in this
manual, the company RAVENNA Mechanical Workshops snc declines from
now all responsibility for any damage to people, animals and / or property
damage caused by improper use.
WARNING!
For loading and unloading, if necessary, use personal protective equipment:
gloves, safety glasses, work boots.
4.5 IN GEAR
After disconnecting the parking brake, the operator driver can move the tractor with the
trailer hooked.
While driving he must move with extreme caution to avoid risk to themselves and to other
persons present within the operating range of the vehicle due to possible movements of the
load. The maneuverability of the tractor is in fact heavily influenced by the presence of the
trailer, especially if the load is full and you have to move in confined spaces and / or slope.
If necessary, in the slopes and in reverse, use the service brake of the trailer.
4.6 UNLOADING THE TRAILER
After stopping the vehicle and entered the parking brake, for unloading, we can distinguish
two cases:
•Bulky items that need to be downloaded using forklifts, cranes or other similar means.
After releasing the load from ropes or chains anchoring the lower body any one or more
banks engage the load with appropriate means and proceed.
