EQUIPMENT & CARGO CARE | Cargo unitization
WLS also makes use of the unitization method as an alternative to the use of slings. This method is mostly used for lumber, plywood, hardboard and veneer, usually stacked two or three units high. However, it also can be applied to other types of cargo, such as pipes and steel cargoes.
Steel bands are strapped around the packages, then pulled tight with the use of tensioners. Upon obtaining the desired tension, the ends of the bands are joined together using specially developed seals.
In addition to damage prevention, the unitization method makes it possible to build up larger master packages, resulting in high handling efficiencies both during loading and discharging operations. The steel bands are removed and disposed of after discharge.
