OPERATING INSTRUCTIONS MANUAL - T739 FARMING TRUCK TRAILER
The trailer wheel sets are composed of:
•
axles
•
road wheels
•
road 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.
1.3.3. LOADING SPACE
The trailer loading space comprises the following:
•
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.
1.3.4. 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 comprises:
•
coupling valve plug;
•
hydraulic lines;
•
single action hydraulic actuator;
•
cut-off valve;
•
fitting and joining hardware.
Fig. 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.

off valve control cable; 5 – coupling valve plug, 6 – control valve;
7 – coupling valve socket.
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.
ATTENTION!
