PRODUCT GUIDE

Stage V mining engine

Suitable for excavators, dump trucks

and front-end loaders, Cummins’

(Columbus, Ind.) QSK60 Stage V engine

is available from

1398-2125 kW

(1875-2850 hp)

with a peak

torque of 11,218

Nm (8,274 lb-ft).

Cummins select-

ed SCR as the best solution to meet

Tier 4 Final and Stage V, saying it deliv-

ers the best balance of installation, ef-

ficiency and total cost of operation. The

fully-integrated aftertreatment unit re-

places the exhaust muffler, minimizing

design modifications. The SCR system

reduces NOx to the required level and

features an integrated decomposition

chamber and Cummins’ airless dosing

system designed to last the life of the

engine. The QSK60 platform delivers

high reliability, and durability, with no

loss of power or torque. Heat rejection

is similar to the Tier 2 engine, so there is

no need to re-engineer the cooling

package.

Fully integrated electric axle

Allison Transmission’s (Indianapolis,

Ind.) ABE Series e-axle advanced ultra-

low floor electric bus powertrain system

integrates dual electric motors, a single-

or multi-speed gearbox (depending on

e-axle model), oil coolers, pumps and

power electronics into a bolt-in system

that replaces the entire traditional pow-

ertrain within the existing frame. It

meets the power and space demands of

the transit bus industry, including heavy

double-decker, articulated and three-

door buses. The ABE Series can operate

without restrictions at regular highway

speeds and on all allowable grades. The

Powershift transmission

The Spicer TE50 powershift transmission

developed by Dana Inc. (Maumee, Ohio)

is designed for large load-haul dumpers,

trucks used in underground mining and

wheel loaders. Engineered for vehicles

from 400 to 600 kW (544 to 816 hp),

the Spicer TE50 transmission offers im-

proved fuel efficiency, smoother shifting,

more precise vehicle handling, and opti-

mized braking. The Spicer TE50 trans-

mission is engineered to fit within cur-

rent vehicle design

envelopes and is

offered with a

four- or eight-

speed gearbox

that provides opti-

mized shifting ra-

tios. It is available

with advanced

automatic lockup, which improves fuel

efficiency by enabling direct drive even

at low speeds. An integrated, automatic

retarder reduces brake wear and enables

smoother, quieter braking. The transmis-

sion is slated to launch with vehicle man-

ufacturers in the second half of 2019.

12.5-L engine

The Cat (Peoria, Ill.) C13B leverages a

proven, reliable core engine with more

than 109 million off-highway field hours

combined with design improvements to

create customer value, allowing OEMs

to downsize their engine platforms,

lower installation costs and maximize

uptime. The 12.5-L engine features a

patented non-EGR aftertreatment sys-

tem to meet EU Stage V and U.S. EPA

Tier 4 Final emission standards and is

available in multiple power ratings from

Fuel-line valve

Designed for fuel supply line emergen-

cy shut-off applications, Global Sales

Group’s (Redmond, Wash.) EZ Oil Drain

Valve EZ Fuel Line Valve features a le-

ver-locking design, but the lever locks

in the “open” position instead of the

“closed” position. It incorporates the

same ball-valve design as previous

models, as well as the special O-ring

design and nickel-plated exterior. New

features include an adjustable lock nut

and red-colored handle. The lock nut

can be used to adjust the final position

of the valve, allowing operators to in-

stall the valve in any position. In addi-

tion, the new red-colored handle cover

improves visibility and allows easier

access of the handle when fuel needs to

be shut off immediately. It is available in

M16-1.5 thread.

system can handle 100% torque in re-

generative braking. It features an axle

rating up to 28,660 lb (13 tons). With

dual motors, it has continuous axle out-

put power of 536 hp (400 kW) and

peak output power of 738 hp (550 kW).

340 kW (456

hp) to 430

kW (577 hp)

with peak

torque reach-

ing 2634 Nm

(1943 lb-ft).

The new engine offers peak power

across a wide speed range enabling

OEMs to optimize machine perfor-

mance based on their application

needs, plus it features high torque rise

for load acceptance. The new after-

treatment system uses diesel oxidation

catalyst, diesel particulate filter and

high-efficiency selective catalytic re-

duction technologies.
