1.交通安全隐患
 
  交通安全隐患包括行车时的交通安全隐患和作业时的交通安全隐患。行车时的交通安全隐患主要来自于疲劳驾驶,感觉疲劳时一定要进服务区休息,不能强撑继续行使。根据桥检车自重大、车身长、高度高的特点,还要考虑过弯的速度及角度,不可进行高速急弯。无论是在行车或者作业时,驾驶人员一定牢记限高和限载标记,限高低于4.2米,限载小于30吨一律不得通过。无限高或限载标记处,由操作员下车指挥缓慢通过。倒车时,也应当由操作员下车指挥完成。作业时的交通安全,是指租用方必须在作业区域内为桥检车办理作业手续并按照高速公路、普通公路停车作业的规定为其提供作业安全防护,夜间作业时提供足够的照明以保证桥检车作业安全。大风(风速超过7级)、雨雪、雷电、有雾天气严禁桥检车作业。
 
2.作业时倾覆隐患
 
  作业时倾覆隐患来源三处:负重(主要是桥架上的人员和物品)、风速、作业区域的平整度和弯度。伸缩臂上的大极限负重为650Kg,所以较多搭载5-6人(含操作员),伸缩臂前端点较大承载2-3人。风速超过7级(局部阵风除外)严禁作业。作业区域是弯度急或者桥面不水平桥梁,严禁作业。
 
  3.作业时雷电隐患
 
  春夏两季或者山区多有雷电发生,桥检车操作员应当随时观察天气变化,发现乌云来袭,立刻停止作业。作业期间每天关注当地天气预报情况,掌握天气状况及风速。
 
  4.作业时外围电场电击隐患
 
  作业区域内常常出现电力线路密布,根据电力强弱不同,分为高压电(钢塔架设)和民用电(水泥柱架设)。无论何种类型桥检车均不得靠近,接触。与高压电线应当保持20米以上的水平距离;与民用电线应当保持5米以上的水平距离。操作员在施放检测臂前,应当提前观察检测区域内的电力线路分布情况(横跨桥梁的,平行桥梁的,下穿桥梁的)。施放和移动过程中确保安全距离, 不得接近和触碰。
 
  5.作业时碰撞隐患
 
  作业区域内无论出现下穿道路或者通航河流,操作员对检测臂高度都要控制在有效范围内。桥孔有下穿道路时,伸缩臂的不能低于桥面底板,严禁占用通道。桥孔下通航河流有过往船只,操作员应当提前观察过往船只的情况,留有充足的空间和时间调整。



1. Traffic safety hazards
Traffic safety hazards include traffic safety hazards during driving and traffic safety hazards during operation. Traffic safety hazards during driving mainly come from fatigue driving. When you feel tired, you must rest in the service area and can not continue to exercise. According to the characteristics of the bridge inspection vehicle from the major, car length, high height, but also consider the speed and angle of the bend, can not perform high-speed sharp bend. Whether it is in traffic or operations, the driver must bear in mind that the limit of Gaohe's limit Mark is less than 4.2 meters, and the limit of less than 30 tons is not allowed to pass. Infinite height or limited load mark, slowly passed by the operator getting off the command. When reversing, the operator should also get out of the car and complete the command. Traffic safety at the time of operation means that the lessor must go through the operation formalities for the bridge inspection vehicle in the operating area and provide it with operational safety protection in accordance with the provisions for parking operations on highways and ordinary highways. Provide adequate lighting during night work to ensure the safety of the bridge inspection vehicle. Strong winds(wind speed above level 7), rain, snow, lightning, fog weather strictly prohibit bridge inspection operations.
2. Overturning hidden dangers during operations
During the operation, there are three sources of hidden dangers: weight(mainly people and items on the bridge frame), wind speed, flatness and bending in the operating area. The large limit load on the telescopic arm is 650Kg, so it is more equipped with 5-6 people(including operators), and the front point of the telescopic arm is larger with 2-3 people. Wind speed exceeding level 7(except local gusts) is strictly prohibited. The work area is urgent or bridge deck is not horizontal bridge, work is strictly prohibited.
3. Thunder during operations
There are many thunderstorms in spring and summer or in mountainous areas. Bridge inspection vehicle operators should observe the weather changes at any time. When dark clouds strike, they immediately stop operations. During the operation, pay attention to the local weather forecast situation every day to master the weather conditions and wind speed.
4. External electric field electric shock hidden danger during operation
In the operating area, there are often many power lines, which are divided into high-voltage power(steel tower erection) and civilian power(cement column erection) according to the power strength. No matter what type of bridge inspection vehicle is not close to, contact. A horizontal distance of more than 20 metres from the high voltage wire shall be maintained; A horizontal distance of more than 5 metres shall be maintained from the civil wires. Before releasing the test arm, the operator shall observe in advance the distribution of power lines in the test area(across bridges, parallel bridges, and underpass bridges). Ensure a safe distance during cast and movement, and do not approach or touch.
5. Collision hidden dangers during operations
In the area of operation, the operator must control the height of the detection arm within an effective range regardless of the presence of underpass roads or navigable rivers. When the bridge hole has a underpass road, the expansion arm can not be lower than the deck floor, and it is forbidden to occupy the passage. There are passing ships in the navigable river under the bridge hole. Operators should observe the passing conditions in advance, leaving sufficient space and time adjustments.
