new MBi selector grapples from inmalo<br />
Inmalo, <strong>the</strong> sole UK importer for MBI<br />
excavator attachments for over 15 years, has<br />
announced a new <strong>and</strong> improved range of<br />
selector grapples for <strong>the</strong> waste management<br />
<strong>and</strong> demolition industries.<br />
The new MBI selector grapple range is<br />
designed for all waste h<strong>and</strong>ling, transfer<br />
station <strong>and</strong> site clearance operations. MBI<br />
(Mantovanibenne) has a continuing product<br />
development programme which constantly<br />
refines <strong>and</strong> enhances <strong>the</strong>ir comprehensive<br />
range. These latest additions, which Inmalo<br />
has available from stock, offer improved<br />
power, performance <strong>and</strong> capacities <strong>and</strong> a<br />
longer working life.<br />
Suitable for carrier excavators <strong>and</strong> materials<br />
h<strong>and</strong>lers of between 3.5-70 tonnes operating<br />
weight, <strong>the</strong> new selector grapple range offers<br />
numerous improvements for <strong>the</strong> recycling <strong>and</strong><br />
demolition specialist. Ranging from 300kgs<br />
to 3900kgs attachment weight <strong>and</strong> 60-1700<br />
litres load volume, <strong>the</strong> new features include<br />
greater capacity by weight, reduced cost by<br />
carrier machine size <strong>and</strong> punch plate jaws for<br />
optimum power-to-weight ratio.<br />
Darby groundworks exp<strong>and</strong>s its Doosan fleet<br />
A Basildon based groundworks<br />
contractor has discovered <strong>the</strong> benefits<br />
of Doosan reduced tailswing excavators<br />
following <strong>the</strong> purchase of a pair of 14<br />
tonne DX140LCR models from local<br />
dealer Promac Solutions.<br />
Darby Groundworks currently operates<br />
a fleet of 40 excavators toge<strong>the</strong>r with<br />
nearly 60 dumptrucks, rollers <strong>and</strong><br />
14<br />
April 2011<br />
All components are manufactured<br />
from hard-wearing 400 Brinel<br />
material <strong>and</strong> <strong>the</strong> grapples feature<br />
teleh<strong>and</strong>lers. The excavators range in<br />
size from 1.5 to 22 tonne of which all<br />
14 of its over 13 tonne machines are<br />
from Doosan <strong>and</strong> in constant use on<br />
sites throughout SE Engl<strong>and</strong>.<br />
Commenting on <strong>the</strong> new Doosan<br />
units, Darby’s plant/transport manager<br />
Robbie Gough said: “When we wanted<br />
some new 14 tonners, <strong>the</strong> only ones<br />
available from<br />
Promac’s stock<br />
were reduced<br />
tailswing units<br />
<strong>and</strong>, to be<br />
honest, we were<br />
initially a little<br />
concerned about<br />
<strong>the</strong>ir stability in<br />
use.”<br />
Once <strong>the</strong><br />
machines had<br />
been put to<br />
work, any fears<br />
“everyone’s talking about it!”<br />
a secure pin retention system <strong>and</strong> 360°<br />
dampened hydraulic rotation for longer<br />
motor life.<br />
over <strong>the</strong>ir performance were quickly<br />
dispelled. “Not only has rear end<br />
damage been virtually eliminated,”<br />
continued Mr. Gough, “But compared<br />
with all <strong>the</strong> o<strong>the</strong>r makes of reduced<br />
tailswing machines we’ve tried in <strong>the</strong><br />
past, <strong>the</strong> Doosan models are far better<br />
balanced, even when lifting steel<br />
reinforcement cages or concrete skips.”<br />
In fact, so effective have been <strong>the</strong><br />
two new diggers that Mr. Gough has<br />
recently placed an order for a second<br />
pair of machines in order to help cope<br />
with an increasing level of activity.<br />
The DX140LCR, which is powered by<br />
a fuel-efficient Cummins common rail<br />
engine developing 71 kw (95 hp) @<br />
just 1900 rpm, has a maximum digging<br />
reach <strong>and</strong> depth of 8.68 <strong>and</strong> 6 m<br />
respectively <strong>and</strong> a swing radius that is<br />
33% less than <strong>the</strong> st<strong>and</strong>ard version – a<br />
protrusion of only 135 mm over <strong>the</strong><br />
700 mm wide tracks chosen by Darby.
