Technical description
Forklift trucks in the 393 series are designed to
handle loading and palletising operations for
loads up to 2.5 t with H 25, up to 3 t with H 30
and up to 3.5 t with H 35.
Details on the exact lift-height-specific maxi-
mum loads are available in the load diagram.
The trucks are eco-friendly an
d their quiet
operation and low level of emis
sions benefit
both the driver and the environ
ment. They
excel on account of their compa
ct design
and a small turning radius, and
they are fully
container compatible. For thi
s reason, the
forklift trucks are particu
larly well-suited for
narrow aisles and operation
al areas where
space is at a premium.
Engine
A 4-cylinder, four-stroke diesel engine with tur-
bocharging and state-of-the-art pump/nozzle
technology is installed as the drive motor. It
powers the truck’s hydraulic pumps and varies
its speed depending on the load. The engine
is cooled by means of a closed coolant circuit
with an expansion tank.
Forced circulation lubrication with an oil pump
in the oil sump is used to lubricate the engine.
The combustion air is cleaned by means of a
dry air filter with a paper insert. Diesel motors
with state-of-the-art technology are used for:
• High torque
• Low fuel consumption
• Low exhaust emissions
• Low particulate emissions
• Low noise levels
Hydraulic system
Thetractiondriveconsistsofahydraulic
variable displacement pump, two hydraulic
fixed-displacement wheel motors (assembled
as a drive axle unit) and a hydraulic pump
(fixed displacement pump) for the working
and steering hydraulics. Direction of travel
and speed are regulated by means of two
accelerator pedals via the hydraulic variable
displacement pump.
The hydraulic fixed-displacement wheel
motors in the drive axle are supplied by the
hydraulic variable-displacement pump and
they power the drive wheels.
Operation
One accelerator pedal each for
forward travel
and reversing (two-pedal oper
ation) is used to
simultaneously regulate the h
ydraulic variable
displacement pump and the engi
ne speed.
The hydrostatic drive enable
s the speed to be
continuously varied in both d
irections, ranging
from standstill up to maximum
speed. The
dual-pedal control means tha
t operation of the
forklift truck is simple, saf
e, non-fatiguing and
efficient.
The driver always has both hands free for
steering and controlling the operational
movements. This results in fast reversing
and efficient stacking.
An optional version is also available whereby
the speed is regulated by an accelerator pedal
(single-pedal operation) and the direction of
travel controlled by means of a travel direction
switch.
To control the operational m
ovements lifting,
lowering and tilting, there
is only one actuating
lever (joystick). Another j
oystickisfittedto
operate additional attachm
ents. Operational
movements can also be contro
lled using
two or four joysticks (singl
e-lever operation
version).
Linde Load Control
The truck’s Linde Load Control (LLC) system
enables:
• Millimetre-perfect and secure mast han-
dling
• Effortless finger-tip contr
ol of all lift mast
functions
• Drive and lifting functions are entirely
separate.
