Old driver needs to get fire protection knowledge of tanker

Before using the tanker, the following preparations should be done: Insert the conductive rod into the ground so that it is “grounded”. If it is dry, it can be watered to make it wet. Needs good protection and good grounding. And check the ground chain, so that it can make good contact with the ground; open the tank truck to manipulate the door, carefully check each valve handle, let it in a closed state; if it is the first time using the oil pump, then If there is no oil in the pump, you need to refuel in advance. You can add 10 liters of oil through the oil inlet. Check the oil screen in the tank car gearbox. The oil level is based on the bottom edge of the socket hole. When the amount of oil is insufficient, gear oil should be added in time.

1. The tanker cannot add gasoline to the carburetor port while it is cranking or when the engine is running. Adding gasoline to the carburetor can increase the concentration of the cylinder gas mixture, although this will be beneficial if the oil fails to enter the cylinder, but it does not help with the failure caused by other reasons. The situation may also result in tempering. In serious cases, there will be damage to burned people and burned vehicles.

2. The tanker should use gasoline to filter the core when maintaining the fuel filter. Some people prefer to use gas-fired ceramic filter cartridges to remove impurities from the filter element when they perform maintenance on the fuel filter. However, the danger of knowing such an operation method is extremely great. If a fire accident occurs, the consequences cannot be imagined. At the same time, such a method has a great influence on the service life of the filter element.

3. When the vehicle is in the oil depot, it cannot use the method of short-circuiting to check the storage condition of the battery. Because the ventilation in the oil depot is generally not very good, and some equipment such as batteries, tarpaulins, and tires will be prevented. If there is missing gasoline on the ground, the sparks generated during the fire fighting may cause The oil molecules in the air ignite.

4, the tanker dragging the subway chain can not eat around the girder. Because the oil and other materials transported by the vehicle are not the same, static electricity is sometimes generated when it is rubbed against another object. The static electricity may cause the fuel to ignite as long as it is a flash fire. Causes fire. Therefore, the bottom line of the oil depot needs to be grounded. The tanker should also be equipped with a grounded iron chain to prevent electrostatic sparks in the tank. The subway chain needs to be placed on the ground. The beam cannot be wrapped. IQ, and the lot can not be less than 50CM. (Text / Sun Ni)

Hoisting Mechanism And Spare Parts

The hoisting mechanism for a Tower Crane typically consists of a combination of a motor, a gearbox, wire ropes, and a hook block. Here is a breakdown of its components and how they work together:

1. Motor: The hoisting motor provides the power needed to lift and lower loads. It is usually an electric motor that generates high torque to handle heavy loads.

2. Gearbox: The motor's rotational motion is transmitted to the hoisting drum through a gearbox. The gearbox helps increase the torque and reduce the speed of the motor, enabling the crane to lift heavy loads at a controlled speed.

3. Hoisting Drum: The hoisting drum is a cylindrical drum around which the wire ropes are wound. It is directly connected to the gearbox and rotates as the motor operates. The drum's size and design determine the amount of Wire Rope it can hold.

4. Wire Ropes:
The wire ropes are wound around the hoisting drum and connected to the hook block. These ropes are made of high-strength steel and have a high load-bearing capacity. Multiple wire ropes are used to distribute the load evenly and ensure stability during lifting operations.

5. Hook Block: The hook block is attached to the lower end of the wire ropes and is responsible for carrying the load. It consists of a pulley system with one or more sheaves, which allows the wire ropes to change direction and support the load securely.

During operation, the motor drives the hoisting drum through the gearbox. As the drum rotates, the wire ropes are wound or unwound, depending on the direction of rotation. This movement raises or lowers the hook block, allowing the crane to lift or lower loads.

The hoisting mechanism is controlled by the crane operator using various controls and switches. Safety features such as limit switches and overload protection systems are also incorporated to prevent accidents and ensure safe lifting operations.
