⟩ Tell me how workers hoist the steel bar in its position?
☛ First they attach iron or steel bar with cables of derricks or crane
☛ One worker will guide the crane or derrick operator with hand signals to move to its position, while another worker will hold the rope attached to the bar to stop it from swinging
☛ Slowly the crane will move structure to its position and once placed workers will check for alignment with the help of plumb bobs
☛ Once the alignment is done, they weld or bolt the bar permanently
