Engine:
Standard:
Cummins - QSB4.5 Turbo EPA Tier 4 Final:
Cummins Model QSB4.5 diesel engine, turbocharged, charge air cooled, 4-cylinder, 4.5-
liter (275 CID). U.S. EPA Tier 4 Final certified. Rated 163 hp (122 kw) at 2600 RPM.
460 foot-pounds (624 Nm) maximum torque at 1500 RPM. 120-amp alternator. Oil
capacity, 11.6 quarts (11 L). Coolant capacity, 33.6 quarts (31.8 L). Electronic controls
for 3 engine speeds during crane operation – 850, 1200, or 1800 RPM, as well as
incremental RPM steps, at 100 RPM steps, between those set points. Protection system
shuts down engine when coolant is too hot or oil pressure is too low. Charge air cooler,
grid heater and engine block heater (which plugs into 120-volt AC extension cord) are
included. Tier 4 Final engines require the use of Ultra Low Sulfur Diesel (ULSD) that
meets the EPA defined sulfur content of 15 parts-per-million (ppm). Tier 4 Final engines
also use Diesel Exhaust Fluid (DEF), and DEF must be added as needed to maintain
proper engine performance. A 5-gallon DEF bottle is located in the fuel tank for easy
access and filling.
Transmission:
Standard:
Powershift transmission with 2 ranges and 3 speeds in FORWARD and REVERSE.
Provides full powershifts between the 3 FORWARD and REVERSE gears at maximum
engine speed. Provides a low range and a high range that can be selected when the
machine is at a STOP. All shifting is done with an electric push button operator interface
in the operator compartment. The transmission includes a front axle disconnect for 2-
wheel drive when commanded by the operator through the electric push button interface
in the operator compartment. The machine must be placed in park before changing from
2-wheel drive or 4-wheel drive. The control system will not allow a change in drive state
without being in PARK. A torque converter with a stall torque ratio of 2.73:1 attaches
directly to engine flywheel to drive transmission. Equipped with oil cooler and filter.
