Crown Equipment Pneumatic Tire Lift Trucks MDX50 - Manual (Page 6)

ENGINE
TB45E 6 cylinder in-line, 4.5 liter with ECCS
(Engine Concentrated Control System)
engine to meet the next generation of low
emission standards. This new low RPM high
torque industrial engine offers a higher
level of engineering excellence through
exceptional emission controls, acceleration,
performance, reliability, and serviceability.
• Three choices: gasoline with multi-port
fuel injection, or LPG with single-port
(throttle body) fuel injection, or a dual-
fuel operation easily switching between
fuels with the fl ip of a switch. All trucks are
equipped with a 3-way catalytic converter.
• All engines utilize an ECCS that
continuously monitors engine component
data from the accelerator pedal, throttle
position, mass-air-fl ow, water temperature,
fuel pressure, and heated oxygen
sensor, for increased sensitivity, reliable
cold starts, and smooth performance
throughout the operating range. An
electronic governor is used for rev-limit
protection.
• Temperature sensor prevents overheating
during high temperature operation by
automatically limiting engine speed until
the coolant temperature returns to within
normal operating range, if the coolant
temperature exceeds a specifi c
temperature, the engine will shut down
automatically. When the engine exceeds
normal operating temperature a dash
displayed warning light is also illuminated.
• Aluminum-alloy head for effi cient cooling.
• Additionally, the low noise level provides
comfort to the operator while driving the
truck. S6D102E diesel 6 cylinder in-line,
5.9 liter 4 stroke cycle turbo-charged direct
injection timed engine that produces high
performance and excellent fuel economy.
The Komatsu S6D102E diesel engine
delivers the power and effi ciency to get
the job done quickly and cost-effectively
while meeting emission requirements.
• The starting system of quick glow spark
(QGS) ensures a quicker and reliable start
in all climate conditions.
FUEL SYSTEM
Gasoline, LPG, or dual-fuel system. Integral
fuel (gasoline or diesel) tank.
• Liquid propane gasoline (LPG) fuel is
available with (optional) 33 lb. or 43 lb. tank.
COOLING SYSTEM
Large capacity, highly effi cient aluminum
radiator
• Easy access reservoir tank for checking or
adding coolant.
• Plastic bladed cooling fan with unequal
pitched blades for additional noise reduction
and effi ciency.
ELECTRICAL SYSTEM
Standard operator conveniences that are
optional on most, such as a complete light
package, horn and hour meter, are standard
on Hamech.
• 12-volt electrical system.
• Alternator with built in I.C. regulator.
• Key-lock, anti-restart ignition switch
(Gas/LPG only).
• Dash displayed fuel level and water
temperature gauges.
• Warning lights for engine oil pressure,
battery charging, brake fl uid level, ECCS
monitor and operation fault indicator.
• ECCS – SST (Service Support Tool)
connector interface for rapid engine
diagnostics.
• Electrically controlled forward-reverse lever
operates at the touch of a fi nger.
HYDRAULIC SYSTEM
The hydraulic system features an integral
reservoir, rebuildable direct drive gear pump,
and fully fi ltered system.
• Large capacity reservoir and radiator cooling
keeps the hydraulic fl uid at an effi cient
operating temperature.
• Load sensing valve in the hydraulic circuit
halts the fl ow of oil to the power steering
system when steering wheel is idle.
FRAME
All welded assembly of heavy gauge steel
with integral hydraulic and fuel tanks.
• Flange type drive axle mounting and heavy
duty engine mounts improve product
reliability.
BRAKES
Hydraulic assisted service brakes with master
cylinder booster are self-adjusting and self-
centering.
• High friction, large diameter brake linings
are housed in the drive axle.
• Enlarged brake covers prevent dirt and
water from entering the linings.
• Mechanical parking brake is actuated from
adjustable toggle handle on dash allowing
for more legroom in the operator’s
compartment.
STEER AXLE
Standard on demand, Fully Hydrostatic
Power Steering.
MAST, CARRIAGE, LBR & FORKS
High-visibility mast assembly with 4 or 6-roller
carriage available in 2-Stage Free-View and
2-Stage or 3-Stage Full Free-View type.
• Sealed bearings for reduced maintenance
with standard side thrust rollers on carriage.
• Equipped with ITA Class IV carriage bars for
mounting forks or a variety off load handling
attachments.
• 48-inch load backrest is standard for
increased load control and operator safety.
• Single and double function internal hosing is
available for operating attachments.
