Bridge Inspection Vehicle Safety Operation Instructions

The sources of potential safety hazards for bridge detection vehicles can be divided into six categories: hidden dangers of traffic safety, overturning of hidden dangers during operations, hidden dangers of lightning during operation, hidden dangers of external electric field during operation, potential collision hazard during operation, and safety hazards of aerial workers.

1, Traffic Safety Hidden Trouble

Traffic safety hazards include hidden traffic safety hazards during operation and hidden traffic safety hazards during operation. Traffic safety hazards during driving mainly come from fatigued driving. When you feel tired, you must rest in the service area. You can't continue to drive because of the bridge inspection vehicle. Due to its heavy body, long body and high height, it is also necessary to consider the speed and angle of cornering. High-speed sharp bends are not allowed. The driver must keep the height limit and load limit mark, limit height or limit load when driving or working. At the marked location, the operator is required to get off the vehicle and direct the vehicle to pass slowly. When the vehicle is reversing, it should also be commanded by the operator to get off the vehicle. The traffic safety at the time of operation means that the renter must perform the operation procedure for the bridge inspection vehicle in the work area and follow the The provisions of highways and ordinary highway parking operations provide operational safety protection and provide sufficient lighting during night operation to ensure the safety of bridge inspection vehicles.

2, overturning hidden trouble during work

Three sources of potential overturning hazards during operation: Load (mainly people and objects on the bridge), wind speed, flatness and camber of the work area. The maximum limit load on the working platform is 800Kg, the maximum load on the front of the working platform is 400Kg, and the wind speed exceeds Class 7 (except for local gusts) Operation is strictly prohibited. The work area is steep or not horizontal and it is strictly prohibited.

3, lightning hazard during operation

In the spring and summer, or in mountain areas, there are many lightning storms. The bridge inspection vehicle operator should observe weather changes at any time and find that dark clouds are coming in. Stop the operation immediately. During the operation, pay attention to local weather forecast conditions every day, and grasp the weather conditions and wind speed.

4, external shock hazards during operation

Electric power lines often appear in the work area and are divided into high-voltage power (steel tower erection) and civil power (cement column erection) depending on the strength of the power. No matter what type of bridge inspection vehicle is allowed to approach, contact with high-voltage wires. A horizontal distance of 20 meters or more shall be maintained; and civil lines shall be maintained at a horizontal distance of 5 meters or more. Before the vehicle is unfolded, the distribution of power lines in the inspection area shall be observed in advance (across bridges, parallel bridges, underpass bridges). ). To ensure a safe distance during casting and movement, do not approach and touch.

5, collision hazards during operation

In the work area, regardless of whether it is crossing the road or navigating a river, the operator must control the minimum height of the detection arm within the effective range. When the bridge hole has a road through the road, the lowest point of the telescopic boom can not be lower than the bottom floor of the bridge, and no passage is allowed. There are passing ships in the navigable river below the bridge hole. The operator should observe the situation of the passing vessel in advance and leave plenty of space and time for adjustment.

6, safety risks for aerial workers

Bridge inspection vehicles are high-altitude vehicles. They should wear non-slip sole shoes to carry out their work. It is forbidden to wear slippers. It is forbidden to drink. It is forbidden to work with high-risk personnel. The escalators must be entered one by one in order, and it is forbidden to get together. The detection platform is forbidden to slap. The operator must be fully focused and not paralyzed. Before doing any operation, observe the state of the vehicle, the condition of the boom, the telescopic boom, the condition of the bridge boom and telescopic boom, the front and rear, and the left and right environmental conditions. The impact of the completion process should be estimated in advance.
