A gantry crane is a kind of machine that is used to lift, lower and move the heavy loads. The movable and fixed hoisting mechanism is a part of this machine. This strong and durable machine runs on a track on the floor or ground level.
The gantry cranes are also available for running on the rubber tires for curbing the need of a track. It can be regarded as an engineering marvel that offers an indigenous support regarding the mobility issues related with goods and payloads. The heavyweight lifting abilities of gantry cranes are additional benefits that can be used. These are also quite a handful for displacing the materials from varied heights.
The design features for the gantry cranes must have the deliverables such as quick lifting of loads, high wind and fatigue resistance, the customization according to needs, using quality steel for ensuring strong and light-weighted frame, the optimum use of the available space, reliable assembly and disassembly, easy availability of spares and repair options, low noise levels, several safety features such as over-speed, over-load and over heightened limiters.
This is done to safeguard the personnel and equipment, high resistance, height and span that involves overhead etc. The swing angle, as well as transfer time, is of high importance for the specifications. It is quite effective for controlling the crane and also robust to parameter variation.
It is also quite inexpensive in comparison to another kind of cranes. It is very helpful where material lifting is required on the frequent basis. If it is required that crane should be set up out of the doors, mostly in the cases when buildings are unable to accommodate a bridge crane, then gantry cranes are extremely useful. The places like shipbuilding, rail yards, warehouses, roads and other construction sites, loading ports, scrap yards, moving heavy containers etc. Thus, gantry cranes are mainly categorized into the broader category of Workstation, Rail Mounted or Container.
Since a long time, human beings make constant efforts for finding the solutions for their heavyweight material and with the passage of time; they succeeded to invent several kinds of machinery to get right assistance in this task. The market is flooded with several kinds of cranes. Gantry cranes bear a special position because of their traits.
Gantry cranes are designed along with two upright beams and crossing them. It bears two legs which are shaped in an A-frame design having wheels on the bottom. It is essential to make it portable and also movable. Various types of gantry cranes are available for fulfilling various tasks in different industries. Hoist Gantry Cranes have great importance in the construction industry.
The container crane type is a ship-to-store rail mounted gantry crane which lifts the containers from the dock and moves the same along the rails to move the containers on the ship. In a similar way, workstation gantry cranes are used for lifting as well as transporting the relatively smaller items around factories or machine shops. This kind of gantry crane remains stable during the loading and mobile during the unloading process.
