All sorts of transport resources have already been loaded with liquids along the top for many years. To enable this top loading to take place, one requires top loading arms and additional equipment such as folding stairs and safety cages which are assembled to form a complete loading platform. This traditional manner of loading is also used in the chemical and food industry besides the oil and gas industry.
While the choice was usually for top loading because of efficiency and safety reasons, bottom loading is being increasingly opted for today. Loading transport resources from the ground is possible for different liquid products and is becoming increasingly commonplace in the oil and gas industry.
