REAR BOGIE ASSEMBLY
The bogie is a structural steel tube frame and plating
that mounts to the rear wall of the scraper bowl. The
assembly provides mounting for the rear wheel
groups, rear brake system, rotating floor cylinders
and tail lights. The rear of the bogie also incorporates
a push type bumper assembly.
The rear bumper design provides a pushing point to
assist the MES34 up a grade or in poor underfoot
conditions (wet, muddy or icy haul road). The
bumper assembly is designed to be pushed straight
on by the pushing (boosting) machine.
Routine HARD bumper contacts by the pushing
(boosting) machine will cause structural fatigue and
result in reduced bogie service life.
Angled blade contact of the bumper will reduce bull
dozer blade to MES34 wheel clearance. Extreme
blade angles will cause blade/bit to wheel contact
and damage MES34 tires. MES34 and pushing
(boosting) machine operators must communicate to
ensure correct contact and maximum wheel to
blade/bit clearance is maintained.
DRAFT FRAME ASSEMBLY
The draft frame assembly is comprised of a
gooseneck, fuel tank and draft arms. This assembly,
along with two sets of hydraulic cylinders, is what
turns the unit and raises and lowers the bowl
assembly. The assembly also provides mounting for
implement control valve assembly, hydraulic
housing, electrical harnesses, protective guards and
work light.
GOOSENECK
The gooseneck is made up of vertical hitch pin and
steering cylinder castings, a ½" top plate, ¾" side
plates and a 1½" bottom plate. The vertical hitch pin
attaches to the tractor and provides the pivot point
for the steering of the unit. The back side of the
gooseneck attaches to the fuel tank to create
mounting for the draft arms.
