Description

A special platform container for steel coil transportation

technical field

The invention relates to a container, in particular to a special platform container for transporting steel coils.

Background technique

The finished products produced by steel production enterprises are generally transported to the user's location in the form of steel coils. At present, steel coil transportation is mainly by sea and land. Among them, sea transportation is to transport steel coils into modified general-purpose containers, while land transportation is mainly divided into railway transportation and road transportation. The main models of railway transportation are railway flat wagons or railway open wagons, and steel seats are installed on the vehicles first. Or straw mats and fixed with wire ropes, and then put the steel coils on the vehicle for transportation; road transportation is mainly to transport the steel coils after being fixed on the vehicle through a special steel frame or steel wire rope.

When the steel coils are placed in a general-purpose container for sea transportation, limited by the space of the general-purpose container, generally a general-purpose container can only load two steel coils or steel coils smaller than the size of the internal space, and the interior of the general-purpose container needs to be modified accordingly. At the same time, when recycling general-purpose containers, the utilization rate is not high due to the large space occupied after stacking.

When steel coils are transported by railway flat cars, the straw mats and steel wire ropes used are disposable materials, which can only be discarded after being transported to the station, and the straw mats need to undergo special anti-flammation treatment, which not only pollutes the environment, but also costs a lot , does not meet the requirements of energy saving and emission reduction.

When using a car for transportation, because the steel coil is heavy, if the loading and reinforcement is not firm during transportation, there is a risk of overturning or falling due to unbalanced load, which poses a huge safety hazard.
