TECHNICAL DATA  
ENGINE  
• Aluminum-alloy head for efficient cooling.  
• 12-volt electrical system.  
• 50-amp hour alternator with built in  
I.C. regulator.  
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 exceptional emission  
controls, acceleration, performance, reliability,  
and serviceability.  
• All engine main (seven) and connecting  
rod bearings are micro-grooved to provide  
smooth operation and reduce wear.  
• Key-lock, anti-restart ignition switch.  
• Additionally, the low noise level provides  
comfort to the operator while driving  
the truck.  
• Starter motor is enclosed with watertight  
connectors and planetary gear reduction  
for higher torque at lower current draw.  
• Three choices: gasoline with multi-port fuel  
injection, or LPG with single-port (throttle  
body) fuel injection, or a dual-fuel opera-  
tion easily switching between fuels with  
the flip of a switch. All trucks are equipped  
with a 3-way catalytic converter.  
FUEL SYSTEM  
• Dash displayed fuel level and water  
temperature gauges.  
Gasoline, LPG, or dual-fuel system. Integral  
fuel (gasoline) tank.  
• Warning lights for engine oil pressure,  
battery charging, brake fluid level, ECCS  
monitor and operation fault indicator.  
• Easy servicing gasoline four function  
electric fuel pump with, a fuel level gauge,  
fuel pressure regulator, and fuel filter.  
• ECCS – SST (Service Support Tool) con-  
nector interface for rapid engine diagnostics.  
• Gasoline/LPG engines utilize an ECS 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.  
• Liquid propane gasoline (LPG) fuel is  
available with (optional) 33 lb. or 43 lb. tank.  
HYDRAULIC SYSTEM  
COOLING SYSTEM  
The hydraulic system features an integral  
reservoir, rebuildable direct drive gear  
pump, and fully filtered system.  
Large capacity, highly efficient aluminum  
radiator with integral torque converter and  
hydraulic oil cooler.  
• Large capacity reservoir and radiator cooling  
keeps the hydraulic fluid at an efficient  
operating temperature.  
• Easy access reservoir tank for checking or  
adding coolant.  
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.  
• Load sensing valve in the hydraulic circuit  
halts the flow of oil to the power steering  
system when steering wheel is idle.  
• Plastic bladed cooling fan with unequal  
pitched blades for additional noise  
reduction and efficiency.  
ELECTRICAL SYSTEM  
Standard operator conveniences that are  
optional on most, such as a complete light  
package, horn and hour meter, are  
standard on Hamech lift trucks.  
 
TECHNICAL DATA  
FRAME  
TRANSMISSION  
BRAKES  
The Komatsu “Powershift” transmission is a  
single speed forward and reverse transmis-  
sion and is built to exacting specifications.  
It is specially designed for use in industrial  
lift trucks.  
Hydraulic assisted service brakes with  
master cylinder booster are self-adjusting  
and self-centering.  
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.  
• High friction, large diameter brake linings  
are housed in the drive axle.  
• Column-mounted electric shift directional  
control lever provides effortless shift for  
forward and reverse.  
• Enlarged brake covers prevent dirt and  
water from entering the linings.  
• Front cross member is an integral part of  
frame for increased structural integrity.  
• Mechanical parking brake is actuated  
from adjustable toggle handle on dash  
allowing for more legroom in the  
operators compartment.  
• Open perforated step on both sides of  
truck for easy entry and exit.  
• Optimized torque converter stall ratio,  
improve torque, and gradeability without  
sacrificing travel speeds.  
DRIVE AXLE  
• Modulating control valve absorbs shock  
during sudden acceleration or travel direction  
change. This function improves plugging  
capability and prolongs transmission life.  
Heavy duty cast steel axle housing supports  
weight of truck and load while full-floating  
axle shafts transmit torque without  
bearing weight.  
STEER AXLE  
Standard on demand, Fully Hydrostatic  
Power Steering.  
• In-line 100 mesh and 25 micron transmis-  
sion oil filter and oil cooler are equipped as  
standard to ensure trouble free operation.  
• Heavy-duty fabricated steel axle with inte-  
gral double-acting, double-ended power  
steer cylinder eliminates drag links and  
tie rods.  
• Flange mounting on frame members  
reduces load deflection increasing stability  
and capacity.  
• Inching pedal reduces the fluid pressure  
to the clutch pack – to creep the truck or  
have high engine RPMs to perform faster  
hydraulic functions.  
• All wheel hub bearing and king pins are  
easily accessible for lubrication and service.  
• Rebuildable clutch pack can be removed  
and re-built without removing the  
transmission.  
 
TECHNICAL DATA  
• Tilting steering console, with infinite  
adjustment through tilt range positions  
instrument panel in full view of operator  
at all times.  
SERVICEABILITY  
MAST, CARRIAGE, LBR AND FORKS  
Excellent access to engine compartment,  
transmission, and radiator areas can be  
achieved without tools. Making daily checks  
and maintenance easier.  
High-visibility mast assembly with 6-roller  
carriage available in 2-Stage Free-View and  
2-Stage or 3-Stage Full Free-View type.  
• Floor mounted automotive-type pedals  
with large ribbed pads for comfort and  
safe operation. Accelerator pedal is  
mounted on a Teflon roller mechanism  
to reduce operator effort.  
• Sealed bearings for reduced maintenance  
with standard side thrust rollers on carriage.  
• The gas cylinder-assisted, one-piece all  
metal engine compartment cover lifts  
easily and is insulated to reduce noise  
and heat.  
• Equipped with ITA Class III carriage bars  
for mounting forks or a variety off load  
handling attachments.
