If you’re looking to climb the career ladder in construction, becoming a Slinger/Signaller is a great place to begin. The journey from Slinger to Crane Operator, and even beyond, is a rewarding path that combines hands-on experience with specialised training.
Here’s how you can map out your construction career, step by step with Ivor King:
Slinger/Signaller
Moving into a Slinger/Signaller role is an excellent starting point for anyone looking to gain entry to the lifting aspect of the construction industry. Here, you’ll be working closely with crane operators and lifting teams, building essential knowledge of lifting operations.
Role Description
Slinger/Signallers are responsible for:
- Attaching lifting accessories to loads
- Directing crane movements with clear signals
- Assessing load security and balance
- Maintaining safe zones during lifting activities
Training Requirements
To become a qualified Slinger/Signaller, you’ll need to complete a recognised training course, such as CPCS A40 or NPORS N402. These courses typically cover:
- Communication and signalling techniques
- Load weight assessment and selection of lifting accessories
- Slinging methods and best practice
- Risk awareness and site safety during lifting
Skill Enhancement
As a Slinger/Signaller, you’ll gain a deeper understanding of:
- How lifting operations are planned and executed
- The importance of teamwork between ground staff and crane operators
- Key safety considerations in complex lifting scenarios
This role also gives you invaluable on-the-ground experience — preparing you for the transition into crane operation.
Transitioning to Crane Operation
Once you’ve built experience as a Slinger/Signaller and understand lifting operations inside-out, you’re in a strong position to become a Crane Operator.
Pre-requisites
Most crane operator training programmes require you to have:
- Experience in lifting operations (such as working as a Slinger/Signaller)
- Strong awareness of site safety protocols
- Good mechanical understanding
- To be eligible to undertake this course, you must have passed the CITB Health, Safety & Environment test no more than two years before the course start date.
Certification
To operate cranes legally and safely, you must obtain a recognised crane operator licence. In the UK, this can be achieved via the NPORS (National Plant Operators Registration Scheme) N103 Crawler Crane or the CPCS (Construction Plant Competence Scheme) A02 Crawler Crane accredited courses.
These programmes cover:
- Crane controls and operation
- Load charts and lifting techniques
- Pre-use inspections and maintenance
- Safety regulations and compliance
Responsibilities
As a crane operator, you’ll take on a critical role on-site:
- Operating tower cranes, mobile cranes, or crawler cranes
- Conducting thorough equipment checks
- Coordinating closely with Slinger/Signallers and site supervisors
- Ensuring compliance with lifting regulations and safety best practices
Further Career Development
Once you’ve established yourself as a crane operator, there are further opportunities to progress your career:
Crane Supervisor
Moving into a Crane Supervisor role involves:
- Overseeing all crane operations on-site
- Coordinating with project managers and lifting teams
- Managing health and safety compliance
- Leading toolbox talks and briefings
Crane Supervisor courses, such as CPCS A62 or NPORS N405 will prepare you for this leadership position, focusing on advanced planning, safety, and communication.
Appointed Person
The Appointed Person is responsible for planning and overseeing all lifting operations — one of the highest levels of responsibility in lifting work.
In this role, you’ll:
- Plan complex lifts
- Select suitable cranes and lifting equipment
- Write risk assessments and lift plans
- Manage legal compliance and documentation
An Appointed Person training course is essential preparation for this senior role.



Continuous Learning
The construction industry — and lifting operations in particular — is constantly evolving. It’s important to engage in ongoing training to:
- Stay updated with new equipment and technology
- Refresh your knowledge of safety standards
- Build leadership and supervisory skills
Progressing from Slinger/Signaller to Crane Operator is a clear and achievable path for those ready to invest in their skills and training.
Starting out in a Slinger/Signaller role enhances your understanding of lifting operations and gives you essential experience in site safety, preparing you for a progression into crane work. With certification and experience, you can then step into the rewarding role of crane operator — and even further into supervisory positions.
