and rain for 10 months of the year, resulting
in muddy slippery slopes. You could say we
have tough working conditions to contend with
almost all year round.”
Vertex excavates clay and till at the quarry as
well as clearing logs and over-burden, taking
a role in waste management and working with
the provincial and local authorities on water
management and environmental issues.
The company has an all-Volvo fleet to tackle its
work in these difficult conditions, with a pair
of Volvo EC360B excavators, five Volvo A25D
articulated dump trucks (ADTs) and a Tier
4-compliant Volvo EC380D crawler excavator
on site.
The EC380D was one of the first delivered in
North America. “When the machine arrived, we
added a few additional accessories to it, such
as the larger 1.5 m digging bucket, a hydraulic
thumb and, because our contract calls for log
clearing, we added the falling object protective
structure (FOPS) to guard the cab from falling
debris,” said Mr Patchett. “It’s a tremendous
machine, plenty of power, great stability,
superior lighting and a cab full of creature
comforts. Even in this till and clay that has
been compacted for centuries, the excavator
has allowed us to improve our cycle times.”
He is also a fan of the Volvo ADTS, something
that clearly runs in the family. “My dad started
his business using Volvo machines, and I’ve
been around them all my working life. When
it came time to buy my own trucks, I wouldn’t
consider any other brand. Because of the
efficiency of the transmission retarders and
exhaust brakes, we haven’t had to replace a
single brake pad,” said Mr Patchett.
Further up the weight classes, January saw
Polish aggregates producer DSS Group acquire
a new 70 tonne class Hitachi ZX670LC-5 for its
quarry at Pilawa Górna in Lower Silesia from
local dealer Tona. The DSS Group – owned by
Dolnośląskie Surowce Skalne– is believed to be
Poland’s largest producer of aggregates.
The facility can produce five million tonnes of
aggregates per year in grades suitable for both
road and rail projects. Bulk deliveries are made
by rail in a 60 km radius of the site, and the
quarry’s location near the E67 highway also
allows for efficient road transport of materials.
“This is the first Hitachi that I’ve worked with,”
said quarry manager Janusz Rydz, “but from
what I’ve heard in the market, Zaxis excavators
are very reliable and durable.”
He continued, “We hope that the ZX670LC-5
will enhance the level of productivity on this
site. Our aim is to reduce the cost of every
tonne of stone extracted. To do this, we are
renewing our fleet of construction machinery
and in this case we believe that we have found
the best solution.”
Machine operator Boleslaw Gazda estimates
the ZX670LC-5 excavates and loads some 600
to 700 tonnes of materials per hour, depending
on the size of the rocks.
“The Hitachi provides a very stable platform –
even working in the challenging conditions of this
quarry – and the loading cycle is good,” he said.
“It’s also fast and precise thanks to the simplicity
and efficiency of the hydraulic system.”

Polonyalı agrega üreticisi DSS Group, Aşağı
Silezya’daki Pilawa Górna ocağında kullanmak
üzere, Ocak ayında, bölgedeki Hitachi bayisi
Tona’dan 70 ton kapasiteli bir ZX670LC-5
ekskavatörü satın aldı. Dolnośląskie Surowce
Skalne’ye ait olan DSS Group şirketinin
Polonya’daki en büyük agrega üreticisi olduğu
düşünülüyor.
İşletme, karayolu ve demiryolu projelerinde
kullanılabilecek kalitelerde, yılda beş milyon
ton agrega üretebiliyor. Büyük teslimatlar,
sahanın etrafındaki 60 km’lik alana demiryoluyla
yapılıyor ve ocağın E67 karayoluna çok yakın
olması, karayoluyla malzeme naklini de verimli
bir seçenek haline getiriyor.
Ocak müdürü Janusz Rydz’ı dinliyoruz:
“Bu, çalıştığım ilk Hitachi modeli oldu. Ancak,
piyasada duyduklarım, Hitachi’lerin son
derece sorunsuz ve dayanıklı makineler olduğu
yönünde.”
“ZX670LC-5 ekskavatörünün, tesisimizde
üretkenliğe katkıda bulunmasını umuyoruz.
Amacımız, her bir ton agrega başına düşen
maliyeti aşağı çekmek. Bunu yapmak içinse,
inşaat makineleri filomuzu yeniliyoruz ve şu
an için bu yolda en iyi çözümü bulduğumuza
inanıyoruz.”
Makine operatörü Boleslaw Gazda,
ZX670LC-5 ekskavatörünün, kaya
büyüklüklerine bağlı olarak, saatte 600 ila 700
ton malzeme kazıp yükleyebildiğini tahmin
ediyor.
“Hitachi, ocaktaki en zorlu koşullarda
çalışırken bile son derece dengeli bir çalışma
platformu temin ediyor ve döngüleri kısa sürede
tamamlıyor. Hidrolik sisteminin basit ve verimli
olması sayesine ise hızlı ve hassas bir çalışma
temin ediyor.”
