TECHNICAL DESCRIPTION
to the right of the driver. The joystick
regulates the functions for lifting,
lowering, boom in/out and the spreader.
The driver's cab fulfils international
safety standards, and is rubbermounted
to protect the driver from vibrations.
Entrance to the cab is on the left side
via the steps on the machine. When the
driver's seat is rotated through 90
°
, it is
also possible to exit the cab from the
right side.
All hydraulic controls for the lifting
functions are grouped on the console
to the right of the driver's seat.
The parking brake and the switch for
selecting additional electrical
equipment instruments, gauges and
warning lights together with the
switches for the direction indicators
and windscreen wipers are located on
the front mounted instrument panel.
Gear control lever on the steer shaft.
The electrical system is 24 V and has
two serial-connected 140 Ah heavy
duty batteries.
The steer axle is mounted in
"spherelastic" bushes which allow
sufficient wheel movements for
stability on uneven ground. The
parallel tierods are between the
steering cylinder and the wheel axles.
The brakes are operated by an oil-
cooled wet disc-braking system. The
foot brakes are controlled by the foot
brake valve which activates the drive
axle. The parking brake is controlled
electrically and activates a hydraulic
cylinder on the drive shaft.
The double hydraulic pumps are
mounted directly on the gearbox. The
system is divided into four circuits -
two for manoeuvring, one for servo
functions and one for steering. The
relief valves in the hydraulic circuits
are installed to prevent the system
from overloading.
The steering is fully servo-assisted. If
the engine should stall, it is still
possible to steer the truck without
servo assistance, although it is heavy
going.
Two control valves, mounted on the
chassis, are controlled from the cab by
a servo-assisted joystick control levers
TECHNICAL DESCRIPTION
Specification SC 4127 TA means:
SC = Silver Container handler
41 = 41 tons lift capacity in
first row
27 = 27 tons lift capacity in
second row
TA = Toplift attachment
CA = Combi attachment
The engine is a water-cooled, turbo-
charged 6-cylinder diesel engine. The
engine drives a four speed trans-
mission using a torque converter. The
gear selection is electrical with three or
four gears for driving front/back. The
torque converter is equipped with an
oil cooler which lies underneath the
radiator. The gearbox has a dis-
engaging valve controlled by the brake
pedal in the cab. This valve disengages
the gearbox so that the operator can
control the brakes whilst maintaining
a high engine speed during stacking
manoeuvres.
The front axle is driven by the gearbox
via an universally jointed drive shaft.
The axle is of the heavy duty double
reduction type. The primary reduction
is through the hypoid crown wheel and
pinion gear set, the differential gears
are carried within the centre of the
crown wheel. The secondary reduction
is achieved by a planetary gear set
within the wheel hub. The wheel hubs
are carried on taper roller bearings,
thus relieving the half shaft of any
loading other than driving torque.
