TECHNICAL DATA

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 self­centering.

• 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.

TECHNICAL DATA

OPERATOR COMPARTMENT

A unique full-fl oating operator compartment
(HSC) designed to isolate the operator from
fatigue producing vibration.

• Deluxe full suspension seat with retractable
seat belt, lateral restraint system, and
adjustable seat travel and reclining is
standard.

• Hydraulic control levers have easy-to-read
international symbols on the contoured
grips and are within easy reach of the
operator.

• Tilting steering console positions instrument
panel in full view of operator at all times.

• Floor mounted automotive-type pedals with
large ribbed pads for comfort and safe
operation.

• Full width fl oor mat provides large non-slip
surface, reduces noise, vibration, and heat.

• Large open steps and convenient assist
handgrip provides easy entry and exit for
the operator.

• Separate inching and braking pedals
provide positive control while reducing wear
on the drive train.

• Trucks come standard with an integral
headlight/turn indicator control. Turn
indicator has automatic return to neutral.

• The overhead guard is full width and offers
excellent visibility for stacking high loads.

SERVICEABILITY

Excellent access to engine compartment,
transmission, and radiator areas can be
achieved without tools. Making daily checks
and maintenance easier.

• The gas cylinder-assisted, one-piece all
metal engine compartment cover lifts easily
and is insulated to reduce noise and heat.

• Cover also features a single latch for locking
down and an open cover catch to prevent
cover from coming down while in open
position.

• Bottom corner of cover is angled to allow
more access into engine compartment for
scheduled maintenance and service.
