Professional Lifting Services (PLS) from
Sheffield was responsible for erecting and
installing the goliath crane with GH staff
support. This was a challenging project due
to the narrow situation of the works but once
again PLS with GH staff made a great job of
erecting and installing the crane in five days.
This is where the exploration and extraction
of minerals is carried out. Then, after the
crushing process, it is transported to San
Nicolás, by means of a belt of approximately
15.3 kilometres in length and with a capacity
of 2000 tonnes per hour.
Here the minerals are processed in a number
of stages to turn them into one of the
products that the company sells. It is where
the following facilities are located:
1 . Crusher Plant: Here the mineral is
reduced by approximately 95%.
2 . Magnetic Separation Plant:
This is where the waste mineral
is separated from the iron ore,
which is then divided into two
types of product. One of these is
known as High-Grade Iron Ore
and is used for sintering and the
other is used to feed the Pellet
3 . Filter Plant: In this stage, the
thickening and homogenisation
operations are carried out, to
leave the ore in a suitable state to
be transformed into pellets.
4 . Pellet Plant: Here the ore
is transformed by subjecting
it to high temperatures and is
then stored and transferred to
the docks at San Nicolás, from
where it is transported around
Bank station capacity upgrade
(bscu) project, London.
London is one of the most cosmopolitan European
cities. Although it is a city with a history that goes
back more than 2000 years, it is also one of the
most modern and contemporary cities, combining
the old city with the city of the future.
It is also one of the most populated cities in the
world, with more than 15 million people living in
the Greater London area, distributed in 32 districts
where communication via the underground is
essential for thousands of people to travel to work,
go shopping and for their social lives, etc. And
London was the first city to implement this form of
underground transportation, in 19th century (1863).
Nowadays, London has around 275 underground
stations in operation and more than 400 km of
active metro lines.
This makes possible the transportation of more
than 3 million passengers each day, with this being
the second biggest metro system in the world in
terms of kilometres (after Shanghai) and of course
the biggest in Europe.
With the growth of the city, the number of stations
has also been growing and in some cases the
capacity of these has to be upgraded. An example is
Bank Station, which is one of the main underground
stations in the old financial district.
For the BSCU Project, Dragados UK ordered
from GH Cranes a very special 35 tonne capacity
goliath crane with a 5.45 m span and 2.75 m useful
cantilever with 10 m high legs and a hook path of
44 m. The capacity of the cantilever was limited to 6
tonnes and due to the works site and location, and
in order to avoid annoying noise for the neighbours,
Dragados attempted to lower this noise level by
making a special complete cover for the trolley.
