Powerful digging
JCB's new JS300 crawler excavator replaces the JS290 and offers po-
tential fuel savings of up to 4 percent. Powered by a six-cylinder Tier 4
interim Isuzu engine, the unit has 216 horsepower. The engine drives
a twin variable-displacement pump hydraulic system, controlled by
JCB's SMART Control work mode that automatically adjusts the
working mode as the operator increases the engine rpm. JCB says it
retains class-leading breakout and lifting forces, and a new tipping ge-
ometry provides an increased vertical wall digging depth.

Lighter mobile jaw plants
Kleemann's new mobile jaw crushers, the Mobicat MC 110Ri EVO
and MC 110 Zi EVO were completely redesigned with lighter trans-
portation weights for improved portability. They weigh in at 85,000
pounds and 87,100 pounds, respectively. The MC 110Ri EVO has
a vibratory feeder with integrated grizzly, while the MC 110Zi EVO
incorporates a vibratory feeder with an independent double-deck
pre-screen. Both feature a crusher inlet of 28 by 44 inches. Small and
medium gradations bypass the crusher, which reduces wear, while a
side discharge conveyor allows fines to be discharged, resulting in bet-
ter end product.

Rugged duty
breaker
Breaker Technology Inc.'s (BTI) BXR
185 is a 15,400-pound breaker that
delivers 18,500 foot-pounds of impact
energy. The unit offers an extra-long-
stroke balanced piston design to im-
prove the power-to-weight ratio. The
large cross-section upper and lower
shock-absorbing isolators reduce vi-
bration feedback to the carrier. BTI's
exclusive front head restraint system
guides the front head within the hous-
ing, reducing loading to the tie rods
and the upper portion of the breaker.

Computer-
modeled
crushing
Sandvik Construction rolls
out Optiagg, a cone-crush-
ing package that includes
computer modeling and analysis,
a redesigned mantle, a concave ring, and other spare parts. The system
works with its CH430, CH440, and CH660 cones. Through computer
modeling, the optimal configuration and setup is determined so the
chamber setup can be fine-tuned to the desired output. Wear and tear
on the mantle and concave ring are also reduced.
