Cargo handling systems
Containers, swap bodies and semi-trailers are handled with crane facilities and mobile equipment. Terminal equipment includes large gantry cranes with and without cantilever arm spanning ten lanes of traffic as well as flexible reach stackers. It is possible to handle 30 loading units an hour with both types of equipment.
Containers are handled with TOP spreaders. The spreader swivel pins dig into the upper corner fittings of the containers and are turned 90° to lock them into position. This handling technology is safe, fast, cost-effective and can easily be automated. Modern port terminals around the world prove this.
Loading units whose structural design makes them unsuitable for top corner fittings have to be picked up on the ground. The side walls of the loading units are fitted with four grappler pockets for this purpose. The grapplers on the handling equipment are attached to the edges and then lifted up. This kind of handling places greater demands on the crane driver, because it is more difficult to position the grapplers. The main thing is to make sure that the grappler sits properly in the grappler pocket, otherwise there is a danger that the load will come crashing down. The distance between the grappler pockets is always 4876 mm for short and long loading units alike. This means that long loading units (13.60 m/45’) are more critical than short ones in terms of the position of the centre of gravity. It is no longer automatically assumed that even longer loading units will be handled with grapplers.
