TECHNICAL DATA
FUEL SYSTEM
FRAME
ENGINE
Gasoline, LPG, or dual-fuel system. Integral
fuel (gasoline or diesel) tank.
All welded assembly of heavy gauge steel
with integral hydraulic and fuel tanks.
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.
• Liquid propane gasoline (LPG) fuel is
available with (optional) 33 lb. or 43 lb. tank.
• Flange type drive axle mounting and heavy
duty engine mounts improve product
reliability.
COOLING SYSTEM
BRAKES
Large capacity, highly efficient aluminum
radiator
• Easy access reservoir tank for checking or
adding coolant.
Hydraulic assisted service brakes with master
cylinder booster are self-adjusting and self-
centering.
• 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 flip of a switch. All trucks are
equipped with a 3-way catalytic converter.
• Plastic bladed cooling fan with unequal
pitched blades for additional noise reduction
and efficiency.
• High friction, large diameter brake linings
are housed in the drive axle.
• Enlarged brake covers prevent dirt and
water from entering the linings.
• All engines utilize an ECCS that
continuously monitors engine component
data from the accelerator pedal, throttle
position, mass-air-flow, 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.
ELECTRICAL SYSTEM
• Mechanical parking brake is actuated from
adjustable toggle handle on dash allowing
for more legroom in the operator’s
compartment.
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.
STEER AXLE
• Alternator with built in I.C. regulator.
Standard on demand, Fully Hydrostatic
Power Steering.
• Key-lock, anti-restart ignition switch
(Gas/LPG only).
MAST, CARRIAGE, LBR & FORKS
• 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 specific
temperature, the engine will shut down
automatically. When the engine exceeds
normal operating temperature a dash
displayed warning light is also illuminated.
• Dash displayed fuel level and water
temperature gauges.
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.
• Warning lights for engine oil pressure,
battery charging, brake fluid level, ECCS
monitor and operation fault indicator.
• Sealed bearings for reduced maintenance
with standard side thrust rollers on carriage.
• ECCS – SST (Service Support Tool)
connector interface for rapid engine
diagnostics.
• Equipped with ITA Class IV carriage bars for
mounting forks or a variety off load handling
attachments.
• Electrically controlled forward-reverse lever
operates at the touch of a finger.
• 48-inch load backrest is standard for
increased load control and operator safety.
• Aluminum-alloy head for efficient 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 efficiency to get
the job done quickly and cost-effectively
while meeting emission requirements.
HYDRAULIC SYSTEM
• Single and double function internal hosing is
available for operating attachments.
The hydraulic system features an integral
reservoir, rebuildable direct drive gear pump,
and fully filtered system.
• Large capacity reservoir and radiator cooling
keeps the hydraulic fluid at an efficient
operating temperature.
• Load sensing valve in the hydraulic circuit
halts the flow of oil to the power steering
system when steering wheel is idle.
• The starting system of quick glow spark
(QGS) ensures a quicker and reliable start
in all climate conditions.
