The intensive development of container transportation vehicles, rail, river and sea transport led to the creation of special materials handling equipment performance, in particular gantry cranes Rail mounted able to perform operations on the movement of goods from one mode of transport to another, taking into account their relative position overload on one area.
Gantry cranes represent the systems of continuous cyclic operation. Nowdays models are largely designed for lifting equipment for handling medium and large-capacity containers of various types and capacities. One of the most important features of container gantry cranes is definitely the ability to cover the large transshipment and storage space, which paved driveways to different modes of transport, road and railway ones. Cranes of this type are mainly used in the terminals with a large turnover rate of handling rail, road, sea, river containers, as well as on container platforms of industrial warehouses. Gantry hoists are equipped with a variety of lifting devices: manual, semi-automatic and automatic operation types.
Gantry container cranes
The cranes are typically offered with no console, one or two consoles, and to work in seaports – lifting console options. Sometimes such valves are mounted on the deck of the vessel, in which case they are called container ship cranes. Such devices are equipped with container ships with one purpose – to load and unload containers regardless of port facilities. These cranes have a bridge with folding consoles or without them. The portal is moved on the deck over the rails. The crane is equipped with a support or trolley corner, often having a swinging boom that allows operation without consoles.
At transfer points (sites) with a low turnover rate container handling gantry cranes are used hoisting capacity of 8 – 10 tons. The capture and release of containers is made using slings and other accessories, such as universal truck frames, made in the form of cross-arms, essential when dealing with containers deformed.
On platforms equipped with multiple gantry cranes 12.5 tons each, containers weighing up to 20 tonnes gross in co-operation of the two cranes can be handled. In this case, the device for gripping the container (manual or automatic) hung on the hooks of the cranes.
The complex crane equipment rail excavators for loading of large containers can be divided into two groups:
- Rail gantry cranes for railway stations and industrial plants with capacity of 20 tons or more;
- Shore cranes for sea and river port capacity up to 32 tons.
As for the production businesses, one of the most successful gantry hoist and overhead cranes manufacturers in the UK is Granada Material Handling, the company with an impressive track record in machinery industry. A seasoned player is known for its ambitious projects with Bentley, Airbus, Siemens and Nissan projects (and that’s just a few examples). Apart from standard equipment GMH provides an opportunity to create the gantry hoist as a custom solution that still meets unsurpassed safety, performance and cost-efficiency standards.
