By clearly indicating the outreach width of the mobile crane's outriggers and the completion of inspections, we aim to unify the intentions of the on-site workers and prevent crane overturning accidents.
Clearly indicate (visualize) the crane's outrigger extension width and the completion of pre-operation inspections so that they can be visually confirmed from all directions (360°), aiming to unify the intentions of the on-site workers and prevent crane overturning accidents caused by human error. Traditionally, the safety officer was responsible for inspecting the crane and confirming the extension width. Workers involved in the operation were performing their tasks without sharing whether the inspections and extension width had been properly completed.
