One of the most important jobs on a building site is that of a slinger/signaller. It requires skill, diligence, and excellent concentration. Slinger/signallers work alongside the lifting teams in order to provide safe direction and supervision to the crane operators.
A slinger/signaller will act as the eyes and ears of the crane operator who is likely to have an obstructed view. When the view is obstructed, the risks involved with loading increase. This is where slingers/signallers come in – they ensure the safety of the operators and everyone else at the site.
