PRESS RELEASE
High
standards ensure fast construction progress
*Demag crane installations support major road building
project in Brazil
*All-terrain portal cranes negotiate slight gradients
*Short project planning and delivery times thanks to
standardization
Düsseldorf, May 17,
2013 A total of 14 Demag portal cranes are being used by the Brazilian project
engineering company SPMAR to complete one of the largest
and most symbolic road construction projects in Latin America. The crane
installations are used for key transport tasks for production and construction
site logistics for completing the Eastern section of the Rodoanel Màrio Covas, São
Paulo.
This 180-km-long ring road circumnavigates the city of millions and is intended
to reduce the very high congestion of the existing road network.
In parts, the road is constructed on columns and
supporting girders. This requires a special construction method, for which the
portal cranes assume major tasks: they transport girders, supports and other
load-bearing elements to the place of installation.
Dr Lars Brzoska, Vice President and Managing Director
of Terex Material Handling states: “Demag crane technology is supporting the
rapid implementation of this road building project. We are pleased that with
our products we have been able to make a major contribution to the
implementation of this infrastructure project that is so important for the region.”
Particular demands were made on the engineering of the
drives because the runway also includes curved sections. Terex Material
Handling therefore also supplied portal cranes that are able to negotiate
curves, and can also negotiate slight gradients over the course of the road.
Terex Material Handling in Brazil has assumed co-ordination of
the crane project, engineering of the crane installations and the structural
steelwork engineering and assembly. The central components of the cranes such
as hoists, controls and drives come from the German production facility in
Wetter/Ruhr.
Vigold Georg, Managing Director Terex Material
Handling in Brazil
states: “With Demag portal cranes, we offer universal solutions for numerous
transport tasks. Thanks to global standardization, our customers benefit from
tried-and-tested crane components and extraordinarily short delivery times.”
About
the construction project
The metropolitan area of São Paulo
in Brazil
is one of the most densely populated conurbations in the world. Approx. 20.5
million people live here – this makes the city the largest in the southern
hemisphere. The roads in and around São
Paulo are chronically congested. The Rodoanel Màrio Covas motorway, which is
180 km long and surrounds São Paulo
in the form of a ring road is intended to provide a remedy. This Southern ring
has been completed; the inauguration of the 43 km Eastern ring is planned for
2014.
This part of the road section passes through an area
of outstanding natural beauty and so the section is being built on stilts, in a
similar way to a bridge. Here a new process is being used in which a
lattice-boom crane positions columns and lays girders on top of them. Since the
terrain is impassable, the girders and other assembly parts are transported by
portal cranes to the place of installation. The rail-mounted cranes travel on
the outer lanes of the already completed road sections. The rails are extended
as construction progresses so that the crane can always reach the place where
the construction material is installed.
14
Portal cranes work under harsh operating conditions
For the construction project, Terex Material Handling
supplied 14 Demag ZVPE double-girder full-portal cranes. Eight identically
crane installations are designed to work simultaneously on four construction
sites of the road building project. With a span of 17 m, they are each able to
serve three lanes for one direction of travel of the future ring road and are
used to transport prefabricated concrete parts. Equipped with a double-rail trolley
and a DR 20 rope hoist, they have a load capacity of 32 tons. The lifting
height is seven metres.
The special requirement: the drive units and brakes
were designed to accommodate gradients of 2.5 %. In addition, the crane
installations were configured in such a way that they follow the curve-shaped
course of the road section.
Moreover, the cranes meet all requirements associated
with outdoor use in the sub-tropical climate zone and the harsh environmental
conditions of construction site operation.
A further six full-portal cranes, each with a span of
18 m, are used for lifting and transport tasks in the production plant for the
construction materials. Four full-portal
cranes with a load capacity of 32 t and two cranes with a load capacity of 16 t
travel on three parallel crane runways measuring 360 m in length. Thanks to
their compact design, they can serve practically every point of the
approximately 28,000 m² production and storage area.
Standardized
portal cranes
The crane installations installed for the road
building project in São Paulo
were planned and designed in accordance with the high global Demag standard for
portal cranes. On the basis of tried-and-tested crane components, international
teams of engineers developed standardized solutions for portal cranes that
focus on universal areas of application and can be adapted in line with
requirements via additional localised options such as radio control, crane
distance controls and two-trolley operation. Demag customers thus benefit from
high-quality and extremely reliable crane components, shortened planning and
delivery times and, as a consequence, higher production efficiencies. Important
reasons why the Brazilian project engineering company opted to use Demag crane
technology.
The
availability and efficient use of crane installations is also guaranteed by a
large network of qualified service engineers.
