What is the prospect of tower crane command industry?

The tower crane commander in the construction site refers to the signalman, which is a very important post. If the command is improper, it will cause immeasurable danger and even endanger life. As for the future, commanding tower cranes requires an examination signal work permit, and the general salary is not very high, and the future is slim.

First of all, talk about his danger:

The bell man is a special type of work in the construction site.

Special types of work need to obtain special operation qualification certificates, mainly including scaffolder, welder, tower crane driver, bell man and so on. Therefore, the signalman needs a certificate approved by the competent department.

The transportation and operation of tower crane can not be separated from signalman.

The tower crane driver is in the operation shed of the tower crane, because he can't see the lifted materials clearly at high altitude. At this time, signalmen need to use walkie-talkies to command, and improper command will cause danger.

It is necessary to strictly implement the requirements of "ten no-lifting" for tower cranes.

It mainly includes ten items, such as overload or unclear weight of the hoisted object, unclear command signal and someone under the hoisted object. Violation of one item is illegal operation, and the bell man is mainly responsible for the accident.

Once again, the future of the signalman:

The signalman is not a manual worker, but he can command with a walkie-talkie. Therefore, most of the signal soldiers on the ground are lesbians and older gay men, and their skills are not very strong, mainly to test their sense of responsibility.

In addition, the signal soldier is a dangerous occupation with no future.
