EOT Cranes have many design features that vary widely according to their major operational needs such as: type of motion of the eot crane structure, type and weight of the load, location of the crane, geometric features and environmental conditions.
Electric Overhead Travelling cranes are commonly used in the refinement of steel and other metals such as aluminum and copper. In manufacturing process, until a factory as a finished product, metal is handled by an overhead crane. These cranes are used to pour raw materials into a furnace, hot metal is being rolled to specific thickness and tempered, and then stored by an overhead crane for cooling, the finished materials are lifted and loaded into trains and trucks by eot crane, and the fabricator uses an eot crane to handle the steel in his factory. The automobile industry uses these types of cranes to handle raw materials. Smaller workstations cranes, such as jib cranes or gantry cranes, handle lighter loads in a work area, such as CNC or saw.
