olvo’s new series of HB
hydraulic breakers for 14
to 70 tonne excavators
is now available in Europe, and
with operating weights of 909
to 6,031kg, the 11 breakers in
Volvo’s HB14 to HB70 series work
together with Volvo excavators,
from the EC140 up to the EC700.
The breakers are said
to be exactly tailored to
the excavators’ hydraulic
technology, as well as being
self-greasing and encased in
fully sealed housing, which
protects the power cell and
reduces noise.
For flexibility and increased
productivity, Volvo said
operators could adapt frequency
to the application using the
breaker’s dual-speed control. A
cushion damper reduces noise
and vibration back through the
machine, for greater operator
comfort and safety, as well as
decreasing the risk of damage
to the boom and arm.
In addition, anti-blank firing
technology is said to prevent
the breaker from continuing
Making
the cut
German manufacturer Rokla
is a new company that has
started production of the
latest generation of Webster
hydraulic cutting units under
the brand name Rockwheel.
Rokla was founded by
Robert Piasecki and Klaus
Volkert, business partners
who left Terex Compact to
start up the new company.
The four models of
medium-performance class
Rockwheel cutting units are
said to have only three main
components – the housing,
motor and cutting heads.
Therefore, the 29 to 110kW
units have no gearboxes.
The company said it thought
gearboxes would offer no
advantage on these models,
which are designed to be
used on 10 to 40 tonne
excavators, but would add to
their cost.
Another Rockwheel-model
designed for 2 to 10 tonne
excavator does sport a
gearbox. This 22kW cutting
unit has a second motor,
which the company claims
doubles its power output and
performance.
The Rockwheel range is
targeted at the demolition
and civil engineering sectors.

Lehmann Aviation has launched
the LA300, a new automatic
drone for professional aerial
images and video, targeted at
the mining and construction
sectors.
The automatic drone requires
no piloting skills or training,
and is said to set new standards
in aerial imaging. It can be
launched by hand, fly for up to
30 minutes and automatically
land in a chosen location.
The device uses a Nokia 1020
camera and all flight data are
transmitted to the drone using
Wi-Fi.
The drone flies at a range of
up to 15km, at speeds of 20 to
80km/h. It is capable of flying in

The LA300 can be launched by

and automatically land in a
chosen location
to strike once material has
been completely penetrated.
HB-Series breakers can also
be adapted to different
applications with a variety of
tools, including moils, pyramid
moils, chisels and
blunts.
