Special cranes<br />
Success trough innovation<br />
Kü<strong>nz</strong> is the European market leader in the container<br />
crane segment. One of the decisive factors in the company’s<br />
success is the capacity for innovation it has<br />
developed over many years. This capacity for innovation<br />
is particularly required in the special crane segment,<br />
in which effective and innovative solutions are required.<br />
In order to do justice to the outstanding achievements<br />
of Kü<strong>nz</strong> co-workers in this area, which is less familiar<br />
to our customers, this issue is devoted to the subject<br />
of special cranes. Kü<strong>nz</strong> recently delivered a special<br />
crane to Rhomberg Bau, a construction company with<br />
its headquarters in Vorarlberg in Austria; this crane is<br />
designed for laying pre-assembled rail tracks 18 metres<br />
in length and is to be used in the Lötschberg Tunnel in<br />
Switzerland. And a gantry crane with a lifting capacity of<br />
2 x 80 tonnes and a width of 14 metres was delivered in<br />
December 2002 to the AGN company for erection work<br />
in the Gotthard Base Tunnel.<br />
Internationally, Kü<strong>nz</strong> is a specialist in fully automatic<br />
electrolysis cranes. Two special cranes for zinc electrolysis<br />
are currently being commissioned for Hindustan Zinc Ltd<br />
in India. The cranes have a lifting capacity of 11.5 tonnes<br />
and a width of 14.56 metres. Two 2 x 10 t gantry cranes<br />
have also been delivered to Chuciquamata in Chile.<br />

Lötschberg Tunnel / Switzerland<br />
At the end of the 2003, the construction company RHOMBERG BAU AG contacted our company. Rhomberg required<br />
a machine for the construction of the Lötschberg Tunnel in Switzerland that fulfilled the following requirements:<br />
transport of prefabricated rail tracks 18 metres in<br />
length<br />
transport of filled concrete mixer drums<br />
very high alignment accuracy for track installation<br />
while at the same maintaining high terminal velocity<br />
very high operational availability<br />
independent power supply<br />
control via radio and on-board control position<br />
compensation for variable crane rail elevations on<br />
both sides of the crane track<br />
Michael Geiger<br />
Working closely with the customer, KÜNZ developed a<br />
crane that meets these requirements. The crane consists<br />
essentially of two gantries connected to each other by a<br />
clasp. It is powered by a diesel unit mounted on the<br />
gantry. The four hoists can be operated individually and<br />
together. The drive mechanisms are located on the gantry<br />
and can be telescoped hydraulically. The crane is currently<br />
being tested on RHOMBERG’s premises.<br />

Special cranes<br />
Chuciquamata in Chile<br />
Storage yard crane for copper electrolysis<br />
Technical data – Gantry crane<br />
Lifting capacity: 2 x 10 tonnes<br />
Auxiliary hoist: 5 tonnes<br />
Track gauge: 16/7 metres<br />
Lifting/lowering: 0-25 metres/min<br />
Crane drive mechanism: 0-135 metres/min<br />
Crane trolley: 0-50 metres/min<br />
Following the modernisation and extension of one of the world’s largest copper electrolysis plants at Chuciquamata<br />
in Chile, Coldelco ordered two gantry cranes for the loading of anodes and cathodes. Cathodes, anodes and tray<br />
containers are handled by the cranes.<br />
The challenge in designing this crane was to combine 3 functions in one grab with the smallest possible external<br />
dimensions. The trolley is equipped with slewing gear that enables +/- 90º positioning of the load. The crane cabin<br />
can travel freely along the main beam. In addition, the crane operator can monitor the picking up and lowering of<br />
loads by means of cameras.<br />
Hindustan – India<br />
Fully automatic electrolysis tank house cranes<br />
Technical data – Tank house crane<br />
Lifting capacity: 11.5 tonnes<br />
Auxiliary hoist: 1.5 tonnes<br />
Track gauge: 14.56 metres<br />
Lifting/lowering: 0-18 metres/min<br />
Crane travel: 0-100 metres/min<br />
The cranes were delivered in April 20<strong>04</strong>.<br />
Assembly was undertaken by a Kü<strong>nz</strong> supervisor.<br />
Kü<strong>nz</strong> cranes are used throughout the world. Two special cranes for a new zinc electrolysis plant are currently being<br />
commissioned for Hindustan Zinc Ltd. in India. The crane is used for the fully automatic manipulation of cathodes<br />
and anodes in the electrolysis cells with an alignment accuracy of +/-2 mm.<br />
