Slinger Signaller is a person who assists the different operators involved in lifting tasks using cranes and other lifting equipment. The role of Slinger Signallers becomes more crucial in scenarios where the crane operator has little chance of monitoring the different aspects involving safe and efficient lifting operations. They provide help and supervision to crane operations team besides directing the entire operations through hand signals. They also ensure that loads are held tightly and the vehicle, lift and crane movement paths are clear.
Slinger Signaller training lays emphasis on long-distance communication through hand signals, ensuring safe working environment, use of reflective armbands and high-visibility clothing, correct field positioning for smooth communication and ease of vision for the operator, and checking the strength of grip on the loads. The training can be general, covering most machines, or particularly designed for cranes, lorry loaders, and reach trucks, etc.
