Multiple Bar Container Liner
This type of Container Liner is mainly used to contain products that do not flow very easily, such as cement or starch.
This is the most common Container Liner as far as rear containment bars are concerned. The container walls themselves perform the function of containment with respect to the pressure exerted by the bulk cargo inside, but when opening the rear door of the container, for loading and unloading, additional steel containment bars are necessary in most cases so that the Container Liner does not deform or even break without the containment of the open rear door.
These bars also prevent the possible displacement of the complete Container Liner outwards when the door is open, and protect the doors from bulging when they are closed.
All containers incorporate springs to anchor the bars, which in turn are inserted into the Container Liner’s own loops to hold them in place.
The location of the bars must be compatible with the elements of possible subsequent loading and unloading. The bars are usually iron, galvanized iron or steel (somewhat stronger than iron) and can be square or circular in cross-section. Their usual dimensions are 40 mm section x 2400 mm long x 2.8 mm thick and they weigh approximately 5.2 kg each.
Three bars are required for 20-foot containers and four bars for 40-foot HQ containers. In many cases, the customer himself purchases the bars locally to avoid high transport costs for shipping the heavy steel bars.
In some cases where the load is not particularly heavy, the restraining bars can be replaced by girths placed in the form of a St. Andrew’s cross. In any case, erection, loading and unloading tests should always be carried out before a decision is made on the most appropriate method of subsequent containment.
