SURFACE DRILLING AND LOADING
On increasing interest in electric excavators,
Blaise points out that the fuel price economy
with an electric excavator is not the main
advantage, rather the electric drive version is an
efficient alternative as it means less vibration
resulting in higher component lifetime; lower
maintenance costs; less noise pollution; high
motor efficiency; and maximum efficiency in
cold climate conditions when combined with an
Arctic kit. The increased demand for electric
machines is mainly from owner operators rather
than contractors, who prefer the greater
flexibility of diesel machines. The electric
Liebherr range now includes models right up to
the largest R9800.
In terms of what the market can expect in the
future for the next generation of shovels from
Liebherr, the company told IM: “We have
identified six main subjects that are driving the
success of our customers. These subjects, the
Liebherr ‘6 pillars’ are: Reliability, Efficiency,
Productivity, Safety, Customer Service and
Environment, all finally impacting the cost per
tonne. Liebherr will focus to improve our mining
range with a focus on these 6 pillars.”
The new EC750E crawler excavator from Volvo
Construction Equipment features “fuel efficiency
innovations, increased productivity and
performance that helps ensure maximum return
on investment.”
The EC750E from Volvo Construction
Equipment is a 75 t class crawler excavator that it
says offers the “perfect combination of power
and stability to deliver high capacity in most
applications.” Powered by Volvo’s Tier 4
Final/Stage IV compliant D16 engine, the heavyduty excavator delivers increased horsepower of
374 kW utilising advanced fuel efficiency
technology, “ensuring an extremely responsive
operation for maximum productivity and
profitability.”
The EC750E also offers an innovative electrohydraulic system, optimised to operate in
harmony with the robust engine, delivering
greater operator control and productivity. The
hydraulics, in combination with Volvo’s advanced
ECO mode, work in unison to reduce internal
losses in the hydraulic circuit – resulting in
improved fuel efficiency without loss of
performance in most operating conditions.
“Built with the operator in mind, the industryleading Volvo cab delivers a superior operator
experience, with a low-noise environment for
optimum operator productivity. Ergonomically
positioned interfaces – including the joysticks,
keypad and LCD monitor – and clear all-around
visibility ensures maximum efficiency and ease of
use. The spacious cab features ample storage
and leg room, 12 air-conditioner vents and
adjustable seat, keeping the operator fresh, alert
and focused.”
