Tower Crane Knowledge sharing：

Tower crane safety inspection focus, tower crane safety inspection should pay attention to the problem

4, lifting mechanism reducer has electromagnetic clutch

When there is an electromagnetic clutch in the reducer of the lifting mechanism of the tower crane, special attention should be paid to the contact status between the electromagnetic clutch and the brush, and at the same time, check the working status of the electromagnetic clutch under-current relay to ensure the reliable work of the electromagnetic clutch.

In the past, there have been accidents caused by excessive wear of the brush of the electromagnetic clutch, failure of the under-current relay and loss of power of the clutch, which resulted in falling objects.

5. Detection of safety protection devices

(1) lifting torque limiter is a vital safety device for tower cranes, lifting torque is a crucial parameter, and over-torque lifting is the most dangerous thing, which may lead to the destruction and death of the machine.

After passing the test, it is worth discussing with colleagues whether to adopt the lead seal form adopted by the power supply bureau for the electricity meter and take photos for evidence. Never allow anyone to adjust the torque limit after passing the test of tower crane.

(2) lifting weight limiter is also a very important safety device, its role is to protect the motor, so as not to let the motor too much overload, and on the other hand is to send a signal to switch the number of poles of the motor in time, so as not to occur high gear lifting heavy load, to prevent the lifting mechanism to appear reverse slipping accident.

6. Personnel's own safety problems during the inspection of upper tower crane big arm

When inspectors on the tower crane arm can check, the tower crane is in operation condition, its zero protection has opened, while the testing personnel contact tower crane driver of most used oral contact, tend to be far.

Tower crane driver to can not hear you clearly, have subconsciously curved body movements, body easily run into operating lever, cause the car misoperation, I test cases happened, fortunately, my reaction is fast, not only cause serious accident;

7. Inspection after the tower crane is attached

(1) the installation height of the attached wall device shall not exceed the range required by the instruction.

(2) record of verticality test.

Shall, in acceptance before again, please check the unit test retest once, at the moment, tower crane box attached to the wall, bar attached to the wall, and the installation of embedded parts are not standard, part of the rental unit or even with a standard bolt used as attached a pin shaft.

The tower crane and the structure of the distance, many are far more than specifications, in such case, be required to install the unit in installation scheme should be attached to the wall bar and embedded parts detailed calculation data.

Testing should be focusing on stiffness of bar attached to the wall and attached to the wall Angle, the tower crane rated load, and the most unfavorable conditions attached to the wall bar visual should no distortion phenomenon, not more than + 8 ° Angle.

In a word, it is an effective means to improve inspection efficiency, inspection quality and inspection personnel's own safety to grasp the key points and key points of tower crane inspection.

The improvement of inspection quality can reduce the occurrence of tower crane accidents and ensure personal and property safety.
