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 investigation work at 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. Additionally, since the poles are made of aluminum, they will buckle before the existing structures do when they come into contact, 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 shape that hooks onto the handrail, making it compatible with a wide variety of work vehicles. The poles installed at the four corners of the bucket are vertically adjustable, allowing them to be retracted after work is completed, enabling the high-altitude work vehicle to operate without removing them. 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.
