"Rigging" in structural engineering terms refers to the act of lifting heavy objects like steel pipes, structural steel elements, building materials, equipment, etc. from one level to another (up or down) with the aid of suspended cables, ropes, spreader beams etc. and the use of a crane, derrick, "come- a- long", pulley system or sometimes pure man power. With over sixteen years of experience, it comes as no surprise that Metal-craft is the leading company when it comes to rigging works.
