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 operators  
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.  
 
TECHNICAL DATA  
OPERATOR COMPARTMENT  
• Separate inching and braking pedals  
provide positive control while reducing wear  
on the drive train.  
COMPLIANCE & APPROVALS  
A unique full-floating operator compartment  
(HSC) designed to isolate the operator from  
fatigue producing vibration.  
Meets or exceeds American National  
Standards Institute, ASME B56.1 – Part III  
Safety Standards for Powered Industrial Trucks.  
Trucks come standard with an integral  
headlight/turn indicator control. Turn  
indicator has automatic return to neutral.  
• Deluxe full suspension seat with retractable  
seat belt, lateral restraint system, and
