says is a world first for machines of this size.
Economiser is designed to take the guesswork
out of compaction with small rollers by providing
a simple display to monitor compaction progress
and identify any soft spots. This information
is relayed to the operator via a simple LED
indicator. Once the number of lights being
illuminated stops increasing, the material is
fully compacted, and so any soft spots will be
indicated by a sudden drop-off in the bar of
lamps. It is now available as an option for all
of the company’s 5th generation small tandem
rollers, from the 1.8 tonne BW80 to the 4.3
tonne BW 138.
Telematics is another area where technology
is changing the way road building machines
can not only be used, but monitored, managed
and even repaired. Roadtec, for example, now
provides its Guardian system as standard on all
of its Tier 4 Interim milling machines (designated
by an ‘e’ in the product number).
Company president Jeff Richmond said, “There
are literally hundreds of machine factors that
can be monitored in real time and a number
of machine functions that we can fix over the
Internet. When a customer calls in, we’re going
to be able to fix him over the phone.”
The company’s latest addition to its range is
the milling range is the RX-100e, a compact
machine capable of a 203 mm cut depth over its
0.5 m drum width. “We’ve always been big in
the big milling market, but not so much in the
smaller stuff, so the RX-100e is important for
us,” said Mr Richmond.
Features on the machine include the ability to
reposition the right-rear leg to allow milling to be
carried out flush to a curb or other obstruction.
Power comes from a 103 kW Cummins engine
and the drum drive is hydraulic. There is also
a variable speed fan that provides the correct
amount of cooling at any one time.
Sister company Astec has launched a new
system called Data Acquisition System Hub
(DASH), which provides a real-time snapshot of
operations from multiple mixing plants, which is
accessible over the web.
This allows managers to analyse trends and
better understand their plant operations. The
system is compatible with a range of Astec’s
control systems and can be accessed by
smart phones and tablet computers as well as
traditional desktop machines.
Game changer?
The Wirtgen Group meanwhile has taken
telematics one step further with its new Witos
system, which was unveiled at Bauma. This
combines the functions of a telematics fleet
management system with software for process
optimisation. The company says this makes it
possible to optimise the entire road building
chain, including milling, paving and compaction,
as well as adopting a just-in-time approach to
the process.
It is a modular system, with two main parts –
Fleet Management and Process Optimisation.
Within the fleet management section, sub-
sections include Fleet View for an overview
of all machines (this can be interrogated for
detailed data on any one unit), Fleet Care for

taburuyla 203 mm kazıma derinliğine

tanıtılmakta. Richmond devam ediyor:
“Büyük kazıyıcılar pazarında daima çok
önemli bir marka olsak da, kompakt sınıfta
aynı konumda değildik. Dolayısıyla, RX-
100e modelinin geliştirilmiş olması bizim
için hayli önemli.”
Makinenin öne çıkan özellikleri arasında,
sağ arka ayağın, kaldırımlar gibi dikey
engellere sıfır konumda kazıma yapılmasını
sağlayacak biçimde konumlandırılabilmesi
de sayılıyor. İhtiyaç duyulan güç, 103
kW’lık Cummins motoru tarafından temin

hızda dönmek yerine sadece gerekli miktarda
soğutma yaparak tasarruf sağlıyor.
Roadtec’in kardeş firması Astec ise, Veri
Toplama Sistem Merkezi (DASH) adını
verdiği, farklı asfalt karıştırma tesislerinden
aldığı işletme verilerini gerçek zamanlı olarak
ağ üzerinden sunabilen yeni sistemi tanıttı.
Sistem, tesis yöneticilerime teknik
gidişatın ve işletme şartlarının daha iyi
anlaşılması olanağını verecek. Çeşitli Astec
kumanda sistemleriyle uyum içinde çalışabilen
DASH, klasik masa üstü bilgisayarların yanı
sıra akıllı telefonlar ve tablet bilgisayarlar
üzerinden de ulaşılabilme özelliğine sahip.
