Lifting operations are a daily necessity to Singapore’s construction, marine, logistics and engineering industries. Whether it is moving heavy steel beams, machinery, containers or equipment, these jobs require precision, coordination and strict safety control. This is where the role of a rigger and signalman comes in.

A Rigger and Signalman ensures that lifting activities are conducted safely, efficiently and without any risk to workers or property. These positions are essential in preventing accidents and complying with occupational safety regulations in Singapore.

Greensafe International - Singapore conducts the WSQ Perform Rigger and Signalman Task (PRST) course to equip individuals with the skills and knowledge to carry out these roles professionally and safely.

Who is a Rigger?

A Rigger is responsible for the preparation and securing of loads prior to lifting by cranes or other lifting equipment. It’s a role that requires both planning and hands-on execution to ensure loads are stable and balanced correctly.

Key responsibilities of a Rigger include:

  • Inspection of lifting equipment e.g. slings, shackles, hooks, chains
  • Calculation of loads weight and centre of gravity
  • Choosing the right lifting gear based on type and weight of the load
  • Secure and attach loads to lifting devices safely
  • Making sure loads are balanced before lifting starts
  • Checking for potential hazards in the lifting area

A Rigger plays a crucial role in preventing load drops, equipment failure, and unsafe lifting conditions.

Who is a Signalman?

A Signalman is a person who communicates with the crane operators to guide the movement of loads during lifting operations. Crane operators often have limited visibility so the Signalman is their eyes on the ground.

Key responsibilities of a Signalman include:

  • Providing standardized hand signals or radio instructions
  • Communication with crane operators during lifting operations
  • Keeping the lifting path free of workers and obstructions
  • Monitoring load movement for safety and accuracy
  • Co-ordinate with riggers and site supervisors
  • Operations will cease if unsafe conditions are identified

Effective communication is the most important skill for a Signalman, as even a small misunderstanding can lead to serious accidents.

Why Are Riggers and Signalmen Important in Worksites?

Lifting operations are one of the most dangerous activities in the workplace. “Without proper coordination accidents can happen such as falling loads, equipment damage or injury to a worker.

Riggers and Signalmen help to:

  • Lifting operations: Minimise workplace accidents
  • Better coordination between ground crew and crane operators
  • Comply with Workplace Safety and Health (WSH) regulations
  • Reduce downtime and boost operational efficiency
  • Ensure a safe workplace for all employees

In industries like construction and marine engineering, these roles are not optional—they are essential for safe operations.
