Block tongs for cranes

Customized manufacture of load handling devices

Not only cranes are manufactured by Kranbau Köthen. Also, load handling devices, such as block tongs, are manufactured individually according to the wishes and requirements of our customers.

An example of such a customer-specific custom-made product is a mechanical block tong (picture). It is planned so that it is optimally suited for use in steelworks thanks to its extremely robust lever construction. There, the block tongs can be used for transporting pressure-resistant billets, blocks or slabs.

The block tong, as seen in the gallery, has a gripping range of 150 mm to 1,150 mm and can be used in work environments from -15 ° C to + 80 ° C. The bolts run in this custom-made product in special bushes, consisting of high-strength bearing steel and their gripping jaws were additionally armored.

In the production of such a block tong customer requests can be considered individually. For example, an upper traverse for bolting and / or hanging in standard hook blocks, but also other geometric dimensions, can be adapted directly to your requirements. Matching hook block packages can also be supplied as an option.

In addition to the customer-specific components, a user manual, spare parts lists, the CE declaration of conformity and test reports are also included.

Safety catch sensor system in load-carrying equipment

Increased safety for ladle cranes

Together with the VDEh-Betriebsforschungsinstitut (BFI — operational research institute), Kranbau Koethen has jointly developed a patented system made up of piezo-electrical sensors that are not affected by environmental influences. This sensor system enables operators to monitor the position of the slat hooks to ensure that the pan suspension gear or the pan is securely in the slat hook safety catch before lifting begins. We place customer requirements and concerns at the heart of everything we do, even in terms of sensor technology.
