Overhead cranes are widely used in terminals, open storage yards, indoor and outdoor warehouses and factory workshops. They are mainly divided into three types: general overhead cranes, metallurgical overhead cranes and simple beam overhead cranes.General overhead cranes can vertically lift and horizontally move heavy loads suspended on hooks or other lifting devices in three-dimensional space. The crane is mainly composed of a hoisting mechanism and trolley traveling mechanism. Through the coordinated operation of these mechanisms, the equipment can complete the lifting and handling of goods within a certain cubical space. Gantry cranes, bridge unloaders and metallurgical overhead cranes all belong to this category of lifting equipment.The bridge frame of the general overhead crane runs longitudinally along the tracks installed on elevated supports on both sides, while the lifting trolley travels transversely on the tracks laid on the bridge frame, forming a rectangular working area. This design makes full use of the space under the bridge for material hoisting and transportation without being restricted by ground equipment.The intelligence of lifting equipment can effectively extend human brain functions. It can automatically take countermeasures against problems arising during operation to optimize the working performance of the equipment and effectively guarantee its safety and reliability.For more information, welcome to visit our official website or contact us.
