State-owned entities, like South Africa’s Eskom, should consider using high-capacity vehicles to reduce overall capital costs, says Council for Scientific and Industrial Research (CSIR) principal research engineer Christopher de Saxe. A high-capacity vehicle is essentially a vehicle that carries more load than what is conventional for the country in which it operates in, and in South Africa, regulations permit vehicles up to 56 t, and 22 m in length – any vehicle that exceeds this would be considered a high-capacity vehicle.
