BREAKERS
medium and heavy industrial demolition,
building renovation, road construction, rock
excavation and mining applications.
The models are the 1,800kg RX26 for carriers
from 20 to 33 tonnes, the 2,200kg RX30 for 25
to 40 tonne carriers, the 2,600kg RX38 for 29
to 46 tonne carriers, the 3,000kg RX46 for 35
to 55 tonne carriers, and the 4,200kg RX 54 for
45 to 70 tonne carriers.
All five feature the company’s PowerControl
Plus combined stroke length and start-up
mode switching valve that the operator can
change in the field without opening the
hydraulic circuit.
This allows the operator to adjust the
operational mode of the breaker to the
application.
Ramtec has introduced three new breakers
under the Robi brand name. Designed for
backhoe loaders, the new models are the
BH32, BH40 and BH52.
Rotar is another to launch a new full line
of breakers. Called the RHB Series, these are
suitable for use on carriers from 1 to 70 tonnes.
Claimed to be among the quietest on the
market, they feature a design that minimises
the number of components that it uses to just
two moving parts.
HYBRID TECHNOLOGY
The new breakers are built as standard on
hybrid technology with a power booster.
A central lubrication system is available
as an option on models from the RHB 140
upwards, with optional power control that
allows the breaker performance to be set
according to the application also available
from the RHB 260 model upwards.
Sandvik has introduced four new Rammer
branded breakers this year in the shape of
three new small range units and the 5011 in
the large range.
The new small breakers are the 255, 355 and
455 that plug a gap in the company’s line up
and are intended for carriers from 1.2 to 5.2
tonnes.
They are ideal for the rental sector, according
to the company, and feature the constant
blow energy operating principle to maximise
productivity and profitability.
The 5011 model fits between the 4099 and
7013, and is for use with carriers from 43 to
80 tonnes.
The new breaker has been designed
around the features first seen on the
smaller 3288 and 4099 breakers.
Many of these launches
illustrate the need for more
power in a smaller package,
and that is something that
applies to premium and no-frills
products alike.
Volvo meanwhile has added a
seven-model HB range of breakers
for compact equipment from 1 to
10 tonnes ranging in weight from
129kg to 577kg.
The company said they had been
tailored for use with Volvo’s quick
couplers on the company’s backhoes,
skid steers and compact excavators.
A cushion damper reduces noise
and vibration through the machine for
greater comfort and safety, as well as
reducing the risk of damage to the boom
and arm.
The operator can adapt the
breaker frequency to suit the
application
using
dual-speed
control. Anti-blank firing prevents
the breaker from striking once
material has been completely
penetrated.
Promove presented its new XP101
breaker at April’s Bauma show in
Munich, Germany.
The company claimed that this
92kg tool boasted 35% more
power than its predecessor, with the
same hydraulic requirements.

Jet engine test site demolished
UK contractor Brown & Mason is using a 4,750 Rammer 5011 breaker during the demolition
of the National Gas Turbine Establishment (NGTE) in Farnborough, Hampshire, which for 50
years was at the forefront of aircraft jet engine development.
The strength of its airhouse, with heavily reinforced concrete walls up to 6m thick
allowed it to be used to test Concorde’s engines at 3,200km/hour. V-bomber, Harrier and
Tornado engines were also tested on the site, as was every gas turbine installed in Royal
Navy Warships. The facility closed in 2000 and is now being cleared to make way for a new
business park.
Covering an area of approximately 45ha, the NGTE facility will produce around 1 million
tonnes of arisings – including half a million tonnes of concrete – during the 12 month
project duration.
The majority of that concrete will be broken out by the Rammer hammer, which is
mounted on a demolition specification Komatsu PC450 excavator. The steel will be
removed from the site for recycling and reuse while the half million tonnes of concrete
will be crushed, processed and retained on site for use in the construction of the new
business park.
Brown & Mason’s new Rammer 5011 hydraulic hammer is one of the first of its kind in
the UK. The new model benefits from a new operating principle that allows the 5011 to be
purpose-matched to individual applications and materials using a simple working mode
selector located on the breaker. Brown & Mason is using a high energy mode to provide a
lower blow frequency for optimum breaking power in the site’s heavily reinforced concrete.
Brown & Mason’s Nick Brown said, “We have tried other brands of hydraulic hammer but
Rammer is the only one tough and powerful enough to withstand the type of contracts
in which we’re involved. All of our equipment has to be exceptionally robust, durable and
reliable. On a programme like this, we can’t afford breakdowns and delays. That is why we
stuck with the Rammer brand.”
