Loaders
Hitachi products are also popular with UK quarry operators.
The first Hitachi ZW330-5 wheel loader in the UK has been
purchased by one of the country’s largest independent quarry
operators, Morris & Perry Ltd, and was delivered to the site after
it had been displayed at the Hillhead exhibition in June.
The new ZW330-5 is equipped with a 12.9-litre six-cylinder
water-cooled turbo engine to deliver a powerful digging
performance. The loader also offers a new clutch cut-off system
to control the timing of the clutch for smooth operation when
loading, regardless of the terrain.
Family-owned Morris & Perry provides aggregates, asphalt
concrete and ready mixed concrete products to customers across
southwest England. The new ZW330-5 will be used to load trucks
in the stockyard, keep access roads clear and push up blasted
materials at its Gurney Slade Quarry in Somerset. Equipped with
a 4.6m
3
bucket, it will load more than 1,000 tonnes of materials
per day.
Also in the UK, the Owen Pugh Group has bought two JCB
457 wheeled loading shovels for loading aggregates at its quarry
in Whitburn, near Sunderland.
The Marsden Quarry, where the new JCB 457s are loading
quarried materials on to vehicles leaving the site on behalf of the
Owen Pugh Aggregates division, provides a range of primary and
recycled construction aggregates.
Andy Mountford, general manager at Owen Pugh Aggregates,
said, “We’re already seeing a positive impact on productivity as a
result of the new machines, and as they boast fuel-efficient Tier
SDLG in Morocco
New machines to meet increased output challenges
T
hought to be Morocco’
s
largest quarry, CCGT
Granulats, lies in a rural
location between Serat and R
abat.
Operations there are on the rise,
as demand for aggregates in the
country booms to meet the needs
of the government’
s highway
expansion plan. Output currently
stands at 5
,000 m

of aggregates
per day.
CCGT owns the landmark quarry,
together with several others in the
country, and has been expanding
its equipment fl
eet to help with
the growing workload. Among the
machines added in the past year
are four SDLG units from Shandong Lingong Construction Machinery, known as Lingong.
Three machines are at the Granulats location and one is at its Concentrium facility close to
Marrakesh.
The first machine on site at Granulats was a 5
tonne lift capacity LG9

wheeled loader,
which arrived 12 months ago. The quarry owners were so impressed with the SDLG machine,
particularly the fuel efficiency and product support from local dealer SB
MH, that a further
wheeled loader, a 7
tonne lift capacity LG9

, plus a 3

excavator, were added.
Youseff Taz
i, the owner of CCGT, said the company was delighted with the output and
performance of the SDLG units.
“
This is our first experience of using a Chinese brand at our facilities, as most of our other
equipment is from established W
estern brands,”
he said. “
B
ut we were pleased with the
performance of the first wheeled loader, and when we took the second wheeled loader and
the excavators we were even more pleased.”
The excavator is employed filling trucks which transfer materials to the crusher. This duty
cycle work exerts high levels of work pressure on the LG6

more than equal to the task. B

The group also purchased seven JCB tracked excavators - one
JS130, two JS160, three JS220 and a JS260 model.
Breaking out
New breakers are constantly hitting the quarrying market.
Finnish manufacturer Metso expanded its rock breaker series
designed for primary stationary crushing stations earlier this year.
The company’s hammer-boom combination is now available for
stationary aggregates production and mining applications.
In this application they are used in primary crushing stations to
break oversized boulders that are fed into the crusher and to clear
clogging in the cavity.
“The remotely controlled hammer-boom combination provides,
without a doubt, the safest solution for clearing clogged crusher
cavities,” said Ilkka Somero, product manager for Metso.
“We have now introduced a range of breaker boom and hammer
combinations and can offer our customers a complete turnkey
solution. Besides the requested primary crusher, Metso can now
offer a comprehensive breaker attachment: a boom with assembly
framework, hammer, related hydraulic power pack and remote
