Safe crane operations in Singapore depend on clear, standardised communication between the crane operator and the ground team — a responsibility that falls exclusively on the Signal Man. Under Singapore’s Workplace Safety and Health (Lifting Operations) Regulations, Signal Men are required for crane-assisted lifting operations and must be trained in standardised hand signals and communication protocols recognised by MOM. IET Pte Ltd supplies MOM-trained Signal Men through ManpowerSupply.sg — providing Singapore construction contractors, structural engineers, and industrial operators with deployment-ready Signal Men for tower crane and mobile crane lifts, structural steel and precast operations, heavy machinery installation, and O&G and marine hoisting operations. Signal men play a crucial role in ensuring safe and accurate load movement, especially in complex or high-risk lifting environments.
As a trusted Signal Man supply agency in Singapore, IET Pte Ltd’s trained Signal Men are proficient in all MOM-recognised standard hand signals for crane communication, radio communication protocols for tower cranes and mobile cranes on large construction sites, exclusion zone management and crowd control during lifting operations, communication with Rigger Men and Lifting Supervisors throughout the lift, monitoring and calling abort procedures when unsafe conditions are observed, and adapting communication methods for different site environments including wind noise, height, and distance challenges. Every Signal Men holds current WSH training certification and a valid MOM Work Permit, verified before deployment. They assist in monitoring surroundings, managing site safety, and ensuring that lifting operations are carried out smoothly without hazards or misunderstandings.
We offer flexible signal man manpower solutions to support construction projects, industrial operations, heavy equipment handling, and specialized lifting tasks. Our professionals are trained to adapt to different site conditions and work closely with lifting teams to maintain efficiency and safety.

Under Singapore’s Workplace Safety and Health (Lifting Operations) Regulations, Signal Men must be trained in MOM-recognised standard hand signals for crane communication, exclusion zone management, and crane communication procedures before performing signalling duties. IET Pte Ltd verifies that all Signal Men hold current WSH signalling training certification before deployment to any Singapore construction or industrial site.
The Signal Man is responsible for directing the crane operator using standardised hand signals or radio communication throughout a crane lift — from the initial load pick-up to the final placement. The Signal Man monitors the lifting zone, calls abort if unsafe conditions are observed, communicates load movement instructions to the crane operator, and coordinates with the Rigger Man and Lifting Supervisor during the lift. A qualified Signal Man is a mandatory requirement for crane-assisted operations under Singapore’s WSH (Lifting Operations) Regulations.
Yes. IET Pte Ltd specialises in supplying complete lifting teams — Signal Man and Rigger Man together from one source. Clients specify the lift date, location, crane type, and load details and IET Pte Ltd confirms team availability within 1 hour. Having both roles supplied by the same agency ensures the team is aligned before arriving on site and reduces coordination complexity for your project or safety team.
