The stands under the tank are not designed to carry loads. The sole task of the stands is to ensure that the tank does not roll during transport and that the tank stands stable when it is lowered to the pit. The stands can carry empty weight of the tank, but can not resist the burden arising when the tank is filled with water/liquid etc., it crushes and causes the tank to roll. If the perimeter of the tank is fed up to 70 cm above the ground, this solution will not be economical, although aboveground application can be possible. Aboveground vertical or horizontal polyethylene tanks are manufactured as single-walled and by rotary molding method. For detailed information: www.ephesusplastik.com
