The new Hyundai HL970 wheel loader is
making its way to the European market this year
at Bauma 2016. The new 23.5 t wheeled loader,
with a 3.6-4.2 m³ bucket capacity, is currently
one of the largest of its stable mates which
comprises the recently introduced 15 t HL955 and
the 18.8 t HL960 completing the new wheeled
loader line up for now. The HL970 is powered by
a Scania DC09 085A Stage IV engine boasting a
A special feature of this BWE is a hydraulic
levelling system that allows the machine to travel
and operate on benches with a longitudinal slope
of up to 11%. This machine is the largest compact
BWE employing this technology. For mines with
inclined seams, this option becomes an
important operational advantage for being able
to selectively excavate along the boundaries of
the layers. The Macedonian machine has a
design rate of 4,800 m3/h (loose), and reaches a
maximum digging height of 23 m with its 27 m
long boom.
On wider applications, Dr Hubrich also stated:
“The BWE has been mainly employed in lignite
and coal mine operations. However, this exciting
technology has an interesting future in
alternative areas where large amounts of
material have to be moved – I am thinking of
larger scale sand mining for construction and
land reclamation, as well as mineral sands
projects. The continuous method of digging and
slowly moving equipment also provides an
excellent opportunity for highly automated
solutions.”

Wheel loader developments
Komatsu America Corp recently introduced its
new WA600-8 wheel loader. Equipped with an
EPA Tier 4 Final certified engine, this latest
addition to the wheel loader family combines an
enhanced lockup torque converter function and
SmartLoader logic to achieve low fuel
consumption and high travel speeds.
By optimising control of engine power, and
improving power train and hydraulic efficiency,
the WA600-8 consumes up to 13% less fuel than
its Tier 3 predecessor. Also, the standard bucket
capacity is increased to 9.2 cubic yards and the
bucket now fills easier, retains material better
and provides better visibility, contributing to
machine efficiency and productivity.
“With significant enhancements in production

capacity and fuel economy, the WA600-8 is
designed to maximise production efficiency in
loading off-highway trucks or load-and carry
applications,” said Rob McMahon, Product
Manager for Komatsu America. “Full rear fenders
with steps and handrails at both sides of the
machine add convenience for daily inspections.
And operators will appreciate enhancements in
cab comfort and machine stability,” McMahon
said. The Komatsu Diesel Particulate Filter (KDPF)
and other after treatment components were
designed in conjunction with the engine for
efficiency and long life. More than 98% of KDPF
regeneration is performed passively, with no
action required of the operator and no
interference with machine operation.

the enhanced lockup torque converter that

solution of EGR and SCR technologies, without
the need for an additional DPF. The new machine
is up to 10% more fuel-efficient in truck-loading
than its Dash 9A Series predecessor, depending
on the application, and has a travel speed of up
to 40 km/h. Bauma 2016 is also the world
premiere for the HL980, with a 5.4 m3 bucket
capacity and weight of 31 t with a net power of
280 kW from a Scania DC13 engine.
Hyundai states: “The robust and powerful
HL970 is well suited to the quarrying, mining,
construction and material handling sectors. The
high-strength design structure and robust system
has been proven by rigorous road tests at various
work sites. The durability of the hydraulic hoses

activates in 2nd, 3rd and 4th gear, provides
optimal engine torque for improved acceleration,
hill-climbing ability, a higher top speed and fuel

and attachments has been improved significantly
compared to the previous generation of Dash 9A
series.”
In addition to its fuel efficiency the HL970
benefits from an ECO Pedal, which when the
operator uses the accelerator ped
