Industry & Occupation
Classification
Summary
Specialist who signals crane operators using hand flags or radio to guide cargo handling operations safely and efficiently.
Description
Crane signalers use hand flags or radio to signal crane operators at construction sites, ports, factories, etc., to safely and accurately lift, move, and lower loads. Signaling methods include JIS-standard hand flag signals, standard signals, and radio communication. They pay attention to the load's center of gravity, surrounding obstacles, pedestrians, etc., and proceed with operations while coordinating with the team. Even in high-altitude work or bad weather, they make calm judgments, and in emergencies, they quickly instruct stops, requiring safety management skills.
Future Outlook
While automation technologies and remote-controlled cranes are advancing, the need for precise human signaling from a safety perspective is expected to remain to a certain extent.
