ATTACHMENTS
Special
service
Mutley Plant Service Ltd of Kent, UK,
is a specialist in themanufacture and
supplier of demolition attachments and
excavator modification, and has recently
been commissioned by several major
UK demolition contractors for bespoke
concrete pulverisers.
It has specially designed amechanical
pulveriser for Brown &Mason to suit
a Komatsu PC800 in the shape of a 6
tonneMPP 85 that offers a crushing
force of approximately 100 tonnes. The
new tool is being used for the stripping
out of the general utilities of a 1960s
vintage coal-fired power station, including
dealing with large cable tracks, smaller
pipes and smaller metal structures.
Mutley developed and produced the
attachment using a special manufacturing
process specifically to allow the pulveriser
to withstand the rigours of metal ripping,
tearing and pulling. Due to this unique
design, the crushing performance has
been enhanced over traditional pulverisers
and speeds up the process compared
to the normal methods of shearing and
cutting of internal lighter materials.
This gives Brown &Mason a versatile
attachment to strip out the internal
infrastructure of the power station.
In addition, Surrey based contractors
Wooldridge Demolition previously
purchased a smaller Mutley MPP 65
mechanical pulveriser to suit a Hitachi
ZX650 for more traditional concrete
crushing and on the back of this has
placed an order for a secondMPP 85 to
complement the its recent acquisition of a
Hitachi ZX850 excavator.
manufacturers that donot compete against
eachother. The success of thisUK approach is
another reason for his feelings of optimism.
Louis saidof developments in the sector:
“I think there are twoways of looking at our
industry. Rotar talks a lot about our improved
hydraulic infrastructure, whichmeans our
competition are all shouting about boosters
and suchbutwhatwe aredoing is using50
mm (1.25 inch) hoses throughout and that
way, by giving theoil the spacewe avoid
backpressure and this in turnhelpswith
cycle times.Wedo all our ownhydraulic
components inhouse anddonot buy them
in.Wehave tomeet theperformanceof the
carriers and I am100% sure thatwe can
reach the same forces andperformance
with a simpler technology just by giving
theoil the space. Toomany attachments are
heatingup and also leading to increased fuel
consumptionon carriers.”
POWER AND PRECISION
When it comes todemolishing concrete
structures or rocks, power andprecision
arewhat is required. Today’s tools provide

safe andworkprogresses swiftly.
