A slinger signaller is more than just a hand signal operator. Their training, responsibility, and communication with the crane operator are critical to a safe lift. Here’s what to expect.
The slinger signaller is one of the most important roles on any crane hire job, yet their contribution is often underestimated. Far from simply giving hand signals, a competent slinger signaller is responsible for attaching loads safely, selecting appropriate lifting accessories, and maintaining clear communication with the crane operator throughout the lift.
Under BS 7121 and LOLER regulations, slinger signallers must be trained and assessed as competent. This training covers load assessment, sling selection and inspection, safe slinging techniques, standard hand and radio signals, and an understanding of crane capacities and limitations.
On site, the slinger signaller works closely with the crane operator to ensure every lift is conducted safely. They assess each load before it’s lifted, select and attach the appropriate slings or chains, check that the load is secure and balanced, and then guide the crane operator through the lift using clear, unambiguous signals.
When the crane operator cannot see the load which is common in many construction scenarios, the slinger signaller becomes their eyes on the ground. This requires excellent communication skills, spatial awareness, and a thorough understanding of the crane’s capabilities and blind spots.
At DM Cranes, we provide qualified slinger signallers as part of our contract lifting service, or they can be hired separately to support CPA crane hire operations. All our personnel hold current CPCS or equivalent certifications and undergo regular refresher training to maintain the highest safety standards.
If you are interested in joining the team as a slinger or lift supervisor then please email a CV to DMCNEWS@DMCRANES.CO.UK. We are specifically looking for team members to work from our Bedford office but also hire from our Goole office.
