3.13
Design of the control system for the hydraulic support is shown in Figure (3.9). The hydraulic
system is equipped with a support with a single acting cylinder. The support foot return is
accomplished by the tensioning springs located inside the support body. Supply conduit is
marked with information decal (5). The supply of hydraulic oil to the support is possible only
when cut-off valve (2) is set to „O” position (open). When towing the trailer, the support must
be folded to transport position and secured with a cotter pin. The cut-off valve must be set to
„Z” position (closed).
3.2.8 LIGHTING SYSTEM
The trailer's electrical lighting system is designed to be supplied from direct current source of
12 V. The trailer's electrical system should be connected to the tractor using an appropriate
connection lead that is a part of the trailer's standard equipment.
