Crane operators control a crane in order to hoist or transfer heavy objects from one level to another. They manoeuvre the crane in such a way that the load comes to a standstill in the required place.
In cases where the crane is mobile on tracks, the crane operator regulates the backward and forward movement. The operator needs to make sure that the cable does not jerk. The crane operator of an outdoor crane may be assisted by ground personnel by means of telephone or by hand signals.
Working conditions vary from place to place. The overhead crane operator is often exposed to the heat, smoke and gases of factories. Weather conditions have an influence on the outside worker. Modern cranes, however, have comfortable cabins.
