Pay attention to safe use and management, to prevent tower crane accident in the bud

Tower crane accidents are caused by many reasons, such as the poor quality of the tower crane, improper operation of the tower crane driver, improper construction sequence, unreasonable, inverted and upside down, and so on. No matter what the cause of the site safety work omission, as long as once there is a safety accident, the consequences are we do not want to see.

1. Before the tower crane is installed, it shall be positioned accurately and reasonably according to the plan and elevation drawings provided by the project department, which shall not only facilitate the installation, but also facilitate the disassembly,The distance between walls should be reasonable.

2. For the installation of multiple tower cranes, it is necessary to consider that the tower crane should not interfere with another tower crane as much as possible within the rotating radius of the tower crane.

According to the geological report provided by the project department, it is necessary to determine whether the ground endurance of the installation location of the tower crane meets the requirements of the specification.

If the tower crane model does not meet the requirements, it is necessary to work out feasible plans together with the technical department of the company, such as pile reinforcement treatment or foundation enlargement, and provide calculation basis.

Then provide the project department with the basic drawing of the tower crane and construct according to the drawing.

3. The reinforcement and concrete of tower crane foundation shall have pledge policy, concrete test block report and urgent inspection form.

Reinforcement according to the basic drawing shall not be cut at will. It shall be valid only after being signed by the supervision department.

After the installation of the tower crane, the settlement should be observed, and the measurement record should be made and archived, so as to find problems and correct them in time, and ensure that the tower crane's perpendicularity is within 3‰.

Summary of 13 articles about the daily maintenance of tower cranes

Doing well the routine maintenance work of tower crane can effectively reduce the probability of tower crane accidents. At the same time, we should strengthen the education and publicity of tower crane safety.

The user has the right and obligation to urge the operator to do well the routine maintenance work of tower crane to maintain their own interests, in order to do the daily maintenance of the tower crane, should do the following work, and its tabular, quantitative, to be operable

(1) check the brake of each mechanism, must work reliably and brake flexible, there should be no dirt on the friction surface

(2) check whether all wires and cables are damaged, and wrap or replace the damaged parts in time

(3) check whether the safety devices are reliable and sensitive

(4) check whether each wire rope has broken wire and wear, if there is broken wire wear more than the provisions of the timely replacement

(5) keep the whole machine clean and timely clean the sundries and dirt of each organization;

(6) check the oil quantity of each reducer. If the oil level is lower than the specified height, it should be supplemented in time. The transmission pulley should be oiled frequently to maintain the lubrication and flexibility of the transmission

(7) check the tightness of connection bolts of each standard section, and check whether there are cracks in welding seams of welding parts

(8) check whether the operation of all institutions is normal and whether there is any noise. If any fault is found, it must be removed in time

(9) check whether the component has yield deformation, and replace it if so

(10) each transmission mechanism must have a protective cover, which cannot be removed at will

(11) regularly check whether structural parts are corroded in large quantities

(12) regularly check the connection bolts and welding seams of structural parts, as well as whether the components are damaged, deformed or loose

(13) the limit switch contacts of all safety devices must be opened and closed reliably, and the contact arc pit should be polished.
