BREAKERS
62
New features
Minimising the number of moving
parts in the latest compactbreakermodels
is another major trend – fewer moving
parts shouldmean less maintenance and
break-downs.
Among those taking a leadon this front
is Caterpillar, which says its newE Series
line of breakers features -47% fewer
parts than the D-Series they replace.
The company said the idea behind this
change was to provide quicker and easier
servicing.
Last summer it added four new breakers to its E Series line,
intended for customers using mini excavators, skid steers and
backhoes inNorth andSouthAmerica.Thenewbreakers are the
H35E,H45E,H55E andH65E, designed for carriers weighing
1 tonne to 9 tonnes.
All four models are available in either standard or silent
configurations, with the latter breakers carrying an additional
‘s’ designation at the end of the model number. The silenced
versions have fully enclosed housings to suppress noise, while
the suspension system includes buffers at the top andbottom to
adsorb reflective forces and isolate the breaker from the carrier.
A suspension jack is also said to help in dampening vibration
and sound during operation. In addition, theH45E andH55E
are available as pin-on and flat-top
units. The flat top models can be used
on Caterpillar machines and those from
other OEMs, while the pin-on models
are used on dedicated hammer-equipped
Cat carriers.
Advanced features
Atlas Copco offers the MB and HB
range of breakers, which include an
advanced energy recovery system that
captures piston recoil energy to increase
performance,
without
additional
hydraulic input.
The twoseriesalso feature thecompany’s
Integrated StartSelect valve, which allows the operator to adjust
the hydraulic breaker start-up behaviour according to the
operating condition in a few simple steps.Meanwhile, the built-
in PowerAdapt overload protection valve shuts off the breaker
when operating pressure is not in line with specifications,
protecting it from breakdowns.
Last year, the company also released its HB 4100 hydraulic
breaker, which is a 4.1 tonne unit for 40 tonne to 70 tonnes
carriers. It features a Vibrosilenced system that is designed to
protect operators against noise and vibrations.
Its equipment has also proved popular within the rental
market, with businesses such as German fleet sales and hire
companyM&VVeit Baumaschinen. It has bought 15 new SB
series hydraulic breakers from the company to add to its fleet of
Volvo’s HB series has proved
a key part of its range of
breakers.
