42 Ausgabe Eins 2011 used in conjunction with SVA engineered walking-beam suspensions. In order to achieve the maximum amount of reliability and value money, these axles have been the ‘first choice’ for DSL since 1995 for the de- sign of their new trailers and the upgrading of the existing fleet. Of the many key factors for Dampier Salts’ choice of SVA transport equipment, safety and reliability were para- mount. As a core value, Dampier Salt Limited seeks to achieve a sustainable injury-free workplace by recognising their employees’ health and safety. Having a state-of-the-art and proven road transport operation is a key part of being able to realistically deliver that policy. In addition, Boomerang Engineering and Howard Porter have supplied bottom dump trailers to Dampier Salt Limited. These trailers have been in operation in excess of 15 years and also operate on BPW heavy duty axles. (ap) Safety and reliability take priority The hopper trailers of SVA must be extremely tough as the salt attacks the material from underneath.

A litre of sea water can therefore produce an average of up to 35 grams of salt. About 30% of salt produced worldwide is crys- tallised from sea water. In France, Spain, Portugal, Italy and Africa, and traditionally also in China, sea water is channelled into artificial shallow basins or lakes, where the water evaporates and the salt gradually crystallises on the bottom of the basin. These basins often take on an intense red to violet colouring created by salt-loving, halophile bacteria. After removal of the remaining water, salt layers form, which are then “har- vested” mechanically or manually by the salt farmers.
