Weightlifting on the Nile

Extreme conditions

Technology from STAHL CraneSystems stands the test in the Egyptian heat.

Up to 140 tonnes heavy and up to 40 metres long: the pre­­fabricated concrete parts made by the Egyptian manu­­­facturers ECPC Company are real heavy­­­weights. On top of this come heat and dust – none of which are a problem for the proven tech­­nology from STAHL CraneSystems, which does not even work up a sweat in the face of such extreme con­­ditions.

The popu­­lation of Egypt has been growing for decades – by about two million people a year. One of the many challenges this fast popu­­lation growth poses for the state is over­­­coming the growing volume of traffic. Although more and more people are using the sub­­sidised rail­­­ways and metro as means of transport, traffic on the roads is also rising: the number of private cars increased from 2.2 to 3.5 million from 2008 to 2013. On top of this, a large part of freight is transported by road. Egypt is therefore investing heavily in infra­­­structure projects such as country­­­wide expansion of roads, bridges and railway lines as well as the metro lines in Cairo and the Nile and Suez Canal waterways.

Pre­­fabricated con­­crete parts are often used to con­­struct the roads and railways. These parts are pro­­duced in a pre­­cast factory and trans­­ported to their destinations once hardened. ECPC Company is one of the leading manu­­­facturers of pre­­­fabricated con­­crete parts in Egypt and is located in Madinat al-Aschir min Ramadan, a town 46 km north-east of Cairo. It manu­­­factures con­­­crete parts for road and tunnel con­struction as well as con­crete pipes for drinking water supply and sewage systems. To serve the growing demands of the Egyptian market, ECPC decided to expand its factory by a new depot with two portal cranes. The con­­tract was awarded to the com­pany ICF Inter­­­national Crane Factory, a certified partner of STAHL CraneSystems, against com­­petition from a French com­­petitor.

The engineers and technicians of Inter­­­national Crane Factory began planning the installation in March 2017. The hoists and components were manu­factured in the STAHL CraneSystems factory in Künzelsau and dispatched on their long journey to Egypt in June 2017. Inter­­­national Crane Factory and STAHL CraneSystems maintained close contact the whole time. Inter­national Crane Factory already installed two double girder portal cranes with a span of 32 metres and lifting capacity of 70 tonnes each in July 2017. Each crane is equipped with an AS 7 wire rope hoist in twin im­­­plemen­­tation with double rail crab. As the ropes of the twin hoist run in opposite directions simulta­­neously, the con­­crete parts are lifted and lowered without any side­­ways movement of the hook and can be positioned exactly. To handle the pre­­­fabricated parts, which can weigh up to 140 tonnes each and reach lengths of up to 40 metres, the two portal cranes can be operated individually or synchronously. The cranes are driven precisely with a total of 32 SR wheel blocks and eight frequency-­­­controlled travel drives. Thanks to the prepared connections, the wheel blocks can be mounted quickly and simply with a head connection.

The reliable technology of STAHL CraneSystems is just the right thing whenever the going gets tough – such as in the hot and dusty environment of Egypt. All com­­po­nents are designed for ambient temperatures up to +45 °C and withstand the harsh conditions effortlessly. Using the standardised, tried-and-tested compo­­nents from STAHL CraneSystems as basis, it was possible to find a high-performance and maintenance-friendly solution fulfilling all customer require­­ments optimally. ECPC Company and Inter­­­national Crane Factory are already planning further projects together, for example installation of a new portal crane with a lifting capacity of 6,300 kg.
