Hoisting is a high-risk industry, is a high-risk work. The reason why the hoisting company said this is because once an accident occurs, there may be a major accident of mass casualties. The cause of hoisting accident is crane state on the one hand and unsafe behavior of human on the other hand.
The person mentioned here mainly refers to the staff directly involved in hoisting. Its behavior refers to the signal command and operation action sent out in the specific hoisting command operation process.
Improper hoisting command
No one can be competent for the specific command of hoisting. This person should have a clear mind, quick reaction, seeing and listening, calm and resolute in handling matters. Understand crane performance and lifting scheme. The signal is clear and the flag is clear. From the beginning of lifting, the success or failure is in his hands. This person's behavior is critical. According to the requirements of soldiers, he is a general.
The commander could not see the object being hoisted
Find a place where you can see the object. The pilot can not see the object, but the commander must be able to see it. The conductor doesn't look at the suspended object. That's a layman. For lifting, the commander must first ensure that he can see the state of the object being hoisted.
The commander couldn't see the crane driver
A signal transmitter or walkie talkie can be set up, but the meaning of the signal must be explained in advance. The hoisting company should reserve the walkie talkie to avoid the shortage of electricity. Don't neglect to look at the suspended object in order to find the driver.
The division of labor is not clear and the posts are not enough
As a result, before and after the left and right can not take care of, can not find problems in the process in time. Many hoisting processes are complex and require the cooperation of many people. Even if the commander has a pair of fish eyes, there are blind corners. Therefore, some key parts should be monitored by special personnel, such as: whether the rotation range will encounter obstacles; whether the multi crane counterweight is off the ground; whether the foundation has signs of subsidence, etc.
Work without certificate
This phenomenon still exists. A layman can lead an expert, but a layman can't do a good job. If you let an electric welder to command the crane, it's just a game of life.
The crane driver disobeyed the command when lifting
It's very dangerous behavior. It is a big taboo in hoisting. No matter who encounters such a driver, stop hoisting and correct his / her incorrect behavior, or change the driver who follows the command. Under normal circumstances, the crane driver must listen to the command, do not make his own decisions, because the position you are in is different from that of the commander, and the state you see is different. Unless overload or crane failure occurs, it is necessary to inform the opportunity in time before operating in a safe direction.
Crane not operated as required
Crane drivers are diligent drivers. In fact, some accidents are often caused by laziness. For example, in order to get off work early, it can be solved by using a parking space or adding more road base plates. As a result, in order to save effort and take a risk, accidents will happen.
The crane was not assembled according to the crane operation manual
As a result, the capacity of the crane may be reduced, the safety device may fail or be invalid, the connector may fall off, the wire rope may jump, etc. in order to solve this situation, it is necessary to form and require the driver to carry out routine inspection before each assembly, and the responsible person shall be the captain.
Failure to perform duties
Generally speaking, major accidents have nothing to do with ordinary crane workers. However, if he is assigned to that post, if he fails to report or deal with the problems in time, it may also lead to accidents. Here we mainly embody a kind of responsibility: responsible for ourselves, responsible for others, responsible for everyone.
Work without certificate
Now many crane workers have not received real training, or "several jobs at the same time.". Lifting is no longer specialized.
The above behaviors of hoisting companies are just a simple list, and there will be many in actual work. Whether the crane driver or the crane commander, or the crane operator, the difference between these dangerous behaviors and the "unsafe state of things" is that things are dead, and people are alive. The state of some things is caused by human beings.
In addition, the hoisting company reminds you that the state of the crane needs to be strictly checked before operation:
1. Before the turntable rotates and moves, it is necessary to ensure that the crane is in the supporting state of outrigger.
2. The four hydraulic legs of the crane are not properly supported or are not in a vertical state.
3. The crane is too close to the garbage heap, foundation and inclined plane when working;
4. Use the arm length combination not given to lift or increase the corresponding value in the performance table.
5. The movable outrigger does not extend to the corresponding position specified in the performance table.
6. The movable outrigger is not fixed after extending.
7. Hook deflection due to incorrect operation.
