Special bridge crane with a grab is intended to handle, lift and transport dry, bulk or lump materials by means of a rope- or attached electro- mechanical or electro-hydraulic grab.
Cranes with a grab can be equipped with multi-jaw grabs. There can be from 3 up to 8 jaws in these grabs. These jaws are of crescent shape for handling of materials which are difficult to scoop such as lumpy ore. Special feed grabs are intended to scoop materials from ship’s holds or wagons. Bridge cranes with the grab are required during work in open areas. They can also operate at high temperatures and under heavy climate conditions of foundry shops.
