Construction riggers assemble, install, position and secure construction rigging such as working platforms, pulleys and winches used to undertake heavy lifting for construction projects. They determine the most effective manner in which to lift the object by examining it, determining its size and weight and deciding on the right equipment. They install and secure cables, ropes and other equipment like pulleys and winches, and erect cranes to assist in the job. They may also erect structural steel or concrete framework, as well as inspecting, repairing and maintaining rigging equipment. Construction riggers work all over the state, from large office buildings to mining sites and schools or hospitals in rural towns.
