Columns are designed to work in an upright position. Their architecture is designed to bear mechanical loads resulting from the weight of the switchgear and conductors for upright installation. Columns must therefore be handled and transported vertically to avoid abnormal mechanical stresses during transportation. They must be moved with great care before or after they are unpacked. This is because the centre of gravity of most equipment is often situated in the upper part and this increases the risk of tipping over backwards or forward of the assembly during handling. There is also a risk of tipping over to the side for assemblies that are not very wide. Take all the necessary measures to limit these risks.
