This purpose built item is the biggest special cylinder ever to be used for a cable car. The pull cylinder has the task of stretching the cables on which the gondolas are suspended. Depending on the number of passengers, the pull force in operation can be as high as 184 tonnes given a bore size of 425 mm.
Alongside the considerable length of the cylinder (17 m), the challenge here was to meet the extremely strict demands this entails. This also resulted in an integrated fall protection device to be developed for clamping the 10 m long piston rod.
The servo cylinders are used in a hydropower plant in Jebba, Nigeria. As part of the modernization of the power plant's machine set, HAINZL is supplying a total of two replacement cylinders for turbine adjustment with servo motor and articulated piston rod. This is a special design with a piston diameter of Ø680mm.
Technical data
HAINZL Systemtechnik has developed a 16-ton cylinder for its customer Primetals Technologies. The heavyweight is used to lift ladles on the ladle turret of a steelworks. With a dead weight of 16 tons, the cylinder is the heaviest cylinder HAINZL has ever designed. The dead weight of the cylinder had to be optimized. Compared to the standard version, a weight saving of around 1,500 kilograms was achieved.
