The Characteristics and Uses of General Gantry Cranes
The portal frame of the gantry crane is composed of the upper bridge frame (including the main beam and end beam), outriggers, and lower beams. In order to expand the crane's operating range, the main beam can extend outriggers to one or both sides to form a cantilever; or use a lifting trolley with a boom to expand the crane's operating range through the pitch and rotation of the boom. The general gantry crane has a hoisting mechanism, a trolley operating mechanism and a large cart operating mechanism. These mechanisms and their parts are generally common to overhead cranes.
The gantry crane is a bridge type crane in which the bridge frame is supported on the ground track by the legs on both sides. The general gantry crane is composed of a gantry, a crane trolley, a cart operating mechanism and electrical parts. Some gantry cranes only have outriggers on one side of the gantry frame, and the other side is supported on the factory building or trestle bridge, which is called semi gantry crane.
The gantry structure of the general gantry crane has many types such as single main beam, box-shaped double beam, truss and so on. The retrieval device usually uses hook, grab, electromagnetic chuck, and can also be dual-purpose (hook + grab, hook + electromagnetic chuck, grab + electromagnetic chuck) or three-purpose (hook + grab + electromagnetic chuck) .Hook gantry cranes are suitable for loading, unloading and transporting various goods in stations, docks, industrial and mining, open-air warehouses and other environments. Grab gantry cranes are suitable for handling various bulk materials such as coal, ore, sand, etc. Electromagnetic gantry cranes are suitable for loading and unloading steel, iron blocks, scrap steel, iron filings and other materials in metallurgical plants and machinery plants. Dual-purpose and triple-purpose gantry cranes are used in occasions where materials often change.
