GENERAL DESCRIPTION OF DESIGN AND FUNCTION
4. GENERAL DESCRIPTION OF DESIGN AND
FUNCTION
The T930 trailer is a steel structure with the load body tipped to the
sides and to the rear. The trailer features a pneumatic service brake
(with variable load braking force control) and a parking brake that is
hand-operated via a screw gear, actuating the friction components of
the axle service brake. The trailer features a complete signalling and
warning system (an electrical system and reflective lights). The trailer
is also suitable for transport on public roads.
The trailer is manufactured in accordance with Directive 98/37/EC
and the following harmonised standards: PN-EN 1853:2002, PN-EN
ISO 4254-1:2006, PN-EN ISO 12100-1:2005, PN-EN ISO 12100-2:2005,
PN-EN 294:1994.
4.1. CHASSIS
The trailer chassis is composed of the following subassemblies: bottom
frame, hitch, support foot, wheel set and fastening components.
The bottom frame and the tow bar are welded structures made of steel
sheet and profiles.
The trailer wheel set is composed of: a single axle, land wheels and
land wheel brakes.
The axle is made of a square bar terminated with plugs on which land
wheel hubs are set by cone bearings. They are single wheels equipped
with drum brakes with the shoes actuated by mechanical expander
cams.
4.2. LOAD BODY
The loading space of the trailer is made of the following:
A sealed load body that rests on two pins which serve as the rotation
axis during work. The body is tilted by two hydraulic actuators with one
end of each set on pins on the frame and the other end on the body.
4.3. LOAD BODY HYDRAULIC TIPPING MECHANISM
The hydraulic mechanism is designed for automatic unloading of
the trailer by tipping the load body backwards. The hydraulic tipping
system is fed with oil from the tractor hydraulic system.
The hydraulic system includes: the coupling valve plug, hydraulic lines,
the single-action hydraulic actuators, and connecting and fastening
components. Figure 1 shows the diagram of the load body hydraulic
tipping system. The lifting and lowering of the load body is controlled
by the DCV in the tractor hydraulic system.
* The actuators limit the tilting angle of the body
during the rearward movement.

GENERAL DESCRIPTION OF DESIGN AND FUNCTION
4.6. BRAKING SYSTEM
The T930 trailer is equipped with the following braking systems:
• Service brake: pneumatically actuated two-line system, operates
the axle wheels; controlled from the driver's seat by pressing the
tractor's brake lever;
• Parking brake: hand mechanical control via a crank lever mechanism
and a screw gear, located on the right side of the trailer and operating
the axle wheels.
• The service brake design ensures automatic braking of all trailer
land wheels if the pneumatic system is accidentally decoupled
between the trailer and the tractor. On customer's request, the trailer
can be alternately equipped with a single-line braking system (i.e. for
adaptation to tractors which support such system configuration).
Figure 4 shows the pneumatic braking system diagram:
a) single-line system;
b) two-line system.

5. STORAGE, SALE AND SHIPPING TO USER
5.1. STORAGE
• Protect the trailer against direct exposure to sunlight and rain. Park
it with its land wheels and with the supports extended and locked (if
the tyres can be exposed to sunlight, reduce their pressure).
• If the trailer is stored outdoors, periodically check for rainwater
accumulation in the trailer. Note all damage to the paint coat. Clean
and degrease spots of damaged paint. Next, repaint with the same
colour and coat thickness.
• Long-term storage is allowed in sheltered rooms only.
5.2. SALE
• The buyer picks the trailer from the manufacturer or the sales
representative on their own, or arranges for the shipping with the
manufacturer.
• The trailer is sold as fully assembled and ready for operation,
complete with the basic equipment listed in section 1.2 of this
manual. All optional accessories or their parts are available at extra
charge.
• The sales representative personnel is required to introduce the
buyer to the design and operation of the trailer, along with safety
requirements and warranty conditions.
• The buyer shall verify the following:
- the trailer is complete, undamaged and with all basic equipment;
- the nameplate located on the load body's front frame crosspiece
and the surface under it has the serial number stamped that
matches the data in the warranty card;
- the warranty card has been properly filled out with the identification
data on the nameplate.
5.3. SHIPPING TO USER
The trailer shall be transported from the sales representative on
wheels as coupled with a tractor or on a low-bed trailer. Before loading
on a low-bed trailer, connect the farming trailer with the transport
hitch and the braking lines of the tractor. Drive the farming trailer to
the low-bed trailer with the extended ramps. Next, secure the farm
trailer with wheel chocks. Afterwards, disconnect the braking system
and decouple from the tractor. Secure the farming trailer with special
transport straps. Before unloading the transported trailer, first extend
the low-bed trailer ramps and release the transport straps used to
secure the farming trailer from falling down in transit. Approach with a
tractor and connect the trailer braking system. Next, remove the wheel
chocks from the trailer. When all of the above has been completed,
drive the trailer from the low-bed.

OPERATION INFORMATION
6. OPERATION INFORMATION
6.1. COMMISSIONING THE TRAILER
*Use only tractors that are fit for service (with the
transport hitch, the pneumatic and hydraulic systems,
and the signalling/warning system working)
IMPORTANT!
Do the following before commissioning the trailer:
• Understand the names and locations of individual assemblies/
components of the trailer
• check the tyre pressure
• couple the trailer with the tractor:
- Set the tow bar hitch-ring of the trailer at the trailer transport hitch
height;
- Couple the hitch-ring with the trailer hitch;
- Secure the hitch pin against falling out;
- Turn off the tractor's engine;
- Engage the tractor's parking brake;
- Release the trailer's parking brake.
- Connect the appropriate sockets and plugs of the following
systems: pneumatic, hydraulic and electrical;
• do the functional checks of the electrical, pneumatic and hydraulic
systems of the tractor and of the trailer, and check leak tightness of
the hydraulic and pneumatic systems on both vehicles;
• check all equipment, connections and safety against accidental
release or breaking.
Do all these actions each time you start the trailer.
Only couple the trailer with the tractor transport hitch
rated for the minimum load of 20 kN. No bystanders
shall remain between the trailer and the tractor when
the two are being coupled.
WARNING!
6.2. LOADING THE BODY
Load the body only when the trailer is coupled with the tractor, parked
on level ground and with the tow bar in the forward driving direction.
Use mechanical loading equipment (cranes, loaders, conveyors, etc.)
to load the trailer.
Spread the load evenly across the entire load body surface. When
transporting materials that exert focused (topical) pressure on the
load body (e.g. large rocks), line the floor with thick planks first. This
will reduce the surface load on the floor and protect it against damage.
If the transported materials protrude from the trailer, follow the
applicable traffic code regulations for proper marking of such loads.
• Do not exceed the permissible payload and
permissible axle loads, otherwise the trailer can
be damaged and the traffic safety compromised.
• The transported load must be secured against
shifting, generating excessive noise and falling
down on the road.
