parts required; increased commonality of parts that decreases stocking
requirements; and decreased vibration levels from the new design.
Pre-production hybrid wheel loader
Volvo Construction Equipment unveiled a
pre-production model of a hybrid wheel loader the company plans to
produce in 2009. The L220F is a 349-horsepower loader in the
7-cubic-yard class; the hybrid version includes an integrated starter
generator and an advanced battery that produces up to 515 foot-pounds of
torque and 67 horsepower. The machine’s parallel hybrid technology
improves fuel efficiency by virtually eliminating fuel used at idle and
by providing more torque at low engine speeds. The integrated starter
generator lets the engine shut down at idle and almost instantly
restarts it on demand by rapidly spinning the engine up to optimum
working speed with a burst of energy from the battery. The starter
generator also adds what Volvo calls a “massive electric torque boost”
to the engine, overcoming the diesel engine’s traditional problem of low
torque at low engine speeds. Volvo says the net result is more power,
better performance, and a 10-percent reduction in fuel consumption.
Efficient cone crusher
