GENERAL DESCRIPTION OF DESIGN AND UNCTION
17
T711 FARMING TRUCK TRAILER – OPERATING INSTRUCTIONS
4. GENERAL DESCRIPTION OF DESIGN AND UNCTION
The T711 is a metal structure with open load surface. The trailer
features a pneumatic service brake and a parking brake that is
manually operated via a screw gear, actuating the friction components
of the rear 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 2006/42/EC
and the following standards:
• PN-EN ISO 1853+A1: 2009E
• PN-EN ISO 4254-1:2009E
• PN-EN ISO 13857:2010P
• PN-EN ISO 12100:2012P.
4.1. CHASSIS
The trailer chassis is composed of the following subassemblies: bottom
frame, turntable frame, turntable, tow bar, wheel sets and suspension
components. The bottom frame, the turntable frame and the tow bar
are welded structures made of steel sheet and profiles.
The trailer wheel sets are composed of: the axles (front and rear),
land wheels and wheel brakes. The axles are made of thick-wall
pipes 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. The trailer axle
suspension consists of steel semi-elliptic leaf springs attached to the
turntable frame and the bottom frame by pins and sliders. The wheel
sets are attached to the springs by bolts.
4.2. LOADING SPACE
The loading space of the trailer is composed of:
The top frame (box frame) that is set on the bottom frame (chassis
frame) in articulated seats secured by pins which serve as pivots
during tilting (tipping) of the top frame (load body/box).
The side walls/boards and their top sections are singular components.
Each component features a separate set of locks for closing and
opening of individual wall and top sections independently of each other
and in any order. These design solutions increase functionality and
facilitate operation of the trailer.
The wall and top section locks are secured against accidental release.
4.3. LOAD BODY HYDRAULIC TIPPING MECHANISM
The hydraulic mechanism is designed for automatic unloading of the
trailer by tipping the load body backwards or sideways. The hydraulic
tipping system is fed with oil from the tractor hydraulic system.
The hydraulic system includes: the coupling valve plug, hydraulic lines,
a single-action hydraulic actuator, a cut-off valve, 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 cut-off valve limits the load body tilt angle during
tipping to the sides. The valve is pre-adjusted by the
trailer manufacturer. Do not adjust it on your own.

and operating the rear tandem axle wheels.
The service brake design ensures automatic braking of trailer land
wheels if the pneumatic system is accidentally decoupled between
the trailer and the tractor.

STORAGE, SALE AND SHIPPING TO USER
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 chocked on a hard-paved ground (reduce tyre
pressure and cover the tyres if there is a risk of exposure to sunlight).
• If the trailer is exposed to weather, 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 the delivery 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. Optional equipment is available for 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 chassis front crosspiece 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.
