Vertical Vibration Test of 35000l Swap body at the University of Stellenbosch

Staying the leading manufacturer requires extensive knowledge of product service conditions and applying new technology to optimise all products. To maintain and expand its technological competence, GRW invests a considerable amount on research and development.

New products undergo extensive prototype testing using in-house facilities as well as other accredited test centres which include facilities of the University of Stellensbosch, SABS Commercial Mechanical Testing Laboratory and Spoornet's Railway Technology Development Centre. An example is the testing of a 35,000 Litre SWAP tank container, which included the following tests: Longitudinal Rail Impact Test at the Spoornet's Railway Technology Development Centre.

Another example of GRW's research projects are a combination of long term (longer than 3 months) and short term measurements (1 day) of the dynamic load conditions to which various tanker models are subjected to during normal operational conditions. These measurements are analysed and used to optimise the design criteria for maximum and fatigue load conditions of the tanker models.
