STAHL CraneSystems GmbH

“The customer didn’t know which way to turn”, Fred Weber, sales representative of STAHL
CraneSystems, recalls. DSD Noell needed an off-standard crane for a project in Cameroon, however was not able to find a suitable manufacturer. Desperate, the Würzburg systems manufacturer enquired of STAHL CraneSystems. The crane technology expert was not able to help out with a crane, but knew a competent crane builder: Eisenbau Weissenburg. Fred Weber brought his two customers up to the table and Eisenbau Weissenburg quoted the complete crane. “As a leading manufacturer of hoists and crane components we have close contacts with many crane builders and systems manufacturers. This means that we can pass enquiries on to a suitable specialist and act as broker between our customers”, Fred Weber says.

Cameroon is situated in West Africa, in the middle of the tropics. It is 65 km from the coastal metropolis Douala to Edéa, a town of 120,000 inhabitants. Here there is a large aluminium foundry, a hydro-electric power station in the River Sanaga provides the electricity required. Outside this hydro-electric power station, for some years now DSD Noell has been building a barrage which is planned to regulate the water level. To permit erection and subsequent maintenance, the water is retained by so-called “stoplogs” – heavy bulkhead gates which must be installed by crane.

The main hoists are two STAHL CraneSystems SHF 60 wire rope hoists with a total S.W.L. of 39 tonnes. They are equipped with frequency inverters and are particularly suitable for the gentle and precise positioning of the heavy stoplogs. An SH 30 wire rope hoist, supplied ex factory with a conversion kit, serves as auxiliary hoist for smaller loads. The customer can refit the hoist from 4/1 to 2/1 reeving when required, permitting double the hoisting speed with half the load. The auxiliary hoist too has a canopy to protect it from the rain.
