Danger source identification of motor vehicle frame
1. Hazard source: The line condition has not been checked. Risk and its consequences description: 1 If the wire is dropped too low, it is easy to get an electric shock and the person can't pass normally. There are vehicles or pedestrians in the crossing and track line. 2 wear exceeded. 3 When the line is too high, it is easy for the locomotive to slide through the crossing when the electric vehicle is driven by the electric bow. The locomotive is easy to collide with the passing vehicle during the taxiing process. Pre-control measures: carefully check the integrity of the wiring. 2. Hazard source: The track condition has not been checked. Description of risks and their consequences: Vehicle derailment is prone to occur. Pre-control measures: carefully check the track. 3. Hazard source: Single lane transportation is not realized in 500 lanes during the transportation of the bracket. Description of risks and consequences: It is prone to collisions between vehicles. Pre-control measures: During the transportation of the brackets, one-way transportation must be carried out in the 500 lanes. Any casual personnel are strictly forbidden, and special personnel should be placed to guard them. 4, the source of danger: the locomotive is not in good condition to drive. Description of risks and consequences: It is easy to cause locomotive rear-end accidents. Pre-control measures: Check the brakes and sanding devices must be in good condition. 5, the source of danger: the bracket is biased, the binding is not strong. Description of risks and their consequences: prone to downfall accidents. Pre-control measures: The bracket should be loaded and balanced to ensure a balanced and stable center of gravity. The center of gravity is consistent with the center of the flatbed. The base is fixed with high-strength bolts, and the insulating material is laid on the top beam. The flatbed is in good condition. 6, the source of danger: attention is not concentrated when driving the locomotive. Description of risks and their consequences: prone to rear-end accidents leading to a drop. Pre-control measures: Attention must be concentrated when driving. 7, the source of danger: fast parking. Description of risk and its consequences: It is easy to cause the dump truck to dump. Pre-control measures: When the motor is stopped, the vehicle running speed is reduced smoothly. 8, the source of danger: the vehicle grabbed the crossing. Description of risk and its consequences: It is easy to cause collision of transport vehicles. Pre-control measures: When the vehicle passes through the intersection, you should watch the whistle, and follow the traffic light signal to drive. No pedestrians or vehicles can pass. 9. Hazard Source: There is no guardianship when handling the down road. Description of risk and its consequences: It is easy to cause objects to pop and hurt people. Pre-control measures: When handling locomotive or flat-car accidents, use special pick-up devices, vehicles to cover up, must have guardians to prevent people from standing in the wrong position, the vehicle turns over when hitting the road, hurting the staff. Galvanized steel can be classified into two main types: hot-dip galvanized steel and electro-galvanized steel.
Overall, galvanized steel is a popular and versatile material that offers excellent corrosion resistance and durability. Its use is widespread in a variety of industries and applications, and it will likely continue to be an important material for many years to come.

Hot-dip galvanization is the most common method of galvanizing steel. In this process, the steel is first cleaned and then immersed in a bath of molten zinc at a temperature of around 450°C. The zinc reacts with the surface of the steel, forming a series of zinc-iron alloy layers that provide excellent corrosion protection.
Electro-galvanization, on the other hand, is a process that involves using an electric current to deposit a thin layer of zinc onto the steel surface. This method is typically used for thinner gauge steel and provides a smoother finish than hot-dip galvanization. However, it may not be as durable as hot-dip galvanization and is typically used for less demanding applications.
In addition to its corrosion resistance, galvanized steel is also fire-resistant and has good thermal conductivity. It is also relatively easy to fabricate and can be formed into a wide range of shapes and sizes, making it a versatile material for various applications.
However, galvanized steel may not be suitablefor all applications. It has a shorter lifespan than some other corrosion-resistant materials, such as stainless steel, and may require regular maintenance to ensure its continued protection against corrosion. Additionally, galvanization can affect the appearance of the steel, giving it a characteristic dull gray or silver color that may not be desirable for some aesthetic applications.
Another consideration with galvanized steel is the potential environmental impact of the galvanizing process. The production of galvanized steel typically involves the use of large amounts of energy and resources, and the disposal of waste products from the galvanizing process can have environmental implications. However, efforts are being made to improve the sustainability of the galvanizing process, such as through the use of more energy-efficient production methods and the recycling of waste materials.
