Crane operators may perform the following tasks:

• make sure that cranes are ready for use by checking controls, instruments and gauges
• check the condition of the ground (e.g. building site) before setting up the crane
• place timber blocks or steel plates under the outrigger pads of the crane
• check that the crane is level on the outriggers before attempting to lift and place a load
• be aware of how much material can be safely hoisted in each load according to the crane's capacity and the weather conditions (e.g. high winds)
• move the crane and position the hook so that doggers can attach loads, slings, shackles and chains
• check crane cabin instruments to make sure that loads hooked on their machines are within safe working limits
• observe and follow the signals given by doggers who direct the moving and positioning of the loads
• maintain cranes by inspecting them for defects or wear, lubricate ropes and winches, and replace worn cables.

Crane operators on building and construction sites work in all conditions.
