To prevent accidents where workers may be caught between the bucket of a high-altitude work vehicle and existing structures due to malfunctions of the work vehicle during inspection and investigation tasks in high places such as under bridges or inside tunnels, poles installed at the four corners of the bucket are extended vertically. This ensures that if a malfunction occurs, the poles will first make contact with the existing structures, creating a safe space within the bucket and preventing accidents. Even when the poles contact the existing structures, they are made of aluminum, which will buckle before the structures, thus preventing damage to the structures and also protecting the bucket of the high-altitude work vehicle from damage. The poles are attached to the bucket using a clamp that hooks onto the handrail, allowing for easy installation and compatibility with a wide variety of work vehicles. The poles installed at the four corners of the bucket can be extended and retracted vertically, allowing them to be stored while still attached by shortening them after work is completed, enabling the high-altitude work vehicle to move without removing them. Additionally, a net to prevent the scattering of concrete fragments is also installed to prevent falling or scattering debris. The system has obtained the Ministry of Land, Infrastructure, Transport and Tourism NETIS registration number CB-160014-A.

This system prevents accidents where workers could be caught between the bucket of a high-altitude work vehicle and existing structures due to malfunctioning of the vehicle during inspection and survey work in high places such as under bridges or inside tunnels. By extending poles attached to the four corners of the bucket vertically, even if a malfunction occurs, the poles will first contact the existing structures, ensuring a safe space within the bucket and preventing accidents. When the poles contact the existing structures, they are made of aluminum, which will buckle before the structures do, thus preventing damage to the structures and also protecting the bucket of the high-altitude work vehicle from damage. The poles can be easily attached to the bucket using a clamp that hooks onto the handrail, allowing for compatibility with a wide variety of work vehicles. The poles installed at the four corners of the bucket are vertically adjustable, and after work is completed, they can be retracted up and down for storage while remaining attached, allowing the high-altitude work vehicle to move as is. Additionally, a net to prevent the scattering of concrete fragments is also installed to prevent falling or scattering debris. It has obtained the Ministry of Land, Infrastructure, Transport and Tourism NETIS registration number CB-160014-A.
