safety precautions should be taken to prevent the tower CRANE from collapsing

14-08-2019

In recent years, the development of the real estate industry has been rapid, and various tower hanging accidents have emerged one after another. Among them, tower hanging collapse accounts for a large proportion. Therefore, preventing tower hanging collapse has become a topic of common concern to the majority of Tower hanging practitioners. The site according to the vast number of tower crane construction, maintenance, research and development personnel summed up the safety experience of tower crane collapse, hope to help everyone.
1, tower lifting operation team qualifications to be reviewed
It is well known that tower cranes are heavy construction equipment, involving electromechanical, high-altitude operations, installation, unloading, operators must have the relevant qualifications. However, some people are "convenient" and do not hesitate to falsely report their qualifications and quickly seek employment.

Site managers also ignore it or even secretly help each other. This opens the door to accidents caused by unprofessional operations in the future. Before the installation of the tower crane, The qualification of the operation of the tower crane must be strictly reviewed, or even given the necessary examination, before it can be allowed to take office is an important step to prevent accidents in the bud.
Review the operating plan, especially the safety plan
Everything is preordained. In the construction of the tower, many people are "happy to do what they want". This is also a very dangerous behavior. Because there is no operation of the law, it often ignores the hidden dangers of accidents, so that the lessons of blood are naturally difficult to avoid. Therefore, before controlling the tower lifting construction, the relevant team must summarize the written tower lifting operation plan, especially to strictly attach a safety plan, and submit it to the construction and supervision party for approval before implementation.

3, the supervisor needs to be equipped with a lifting professional supervision engineer, to achieve effective auditing
The role of the supervision department in the construction is that the executing agency or the executor must also take organizational, coordination, control, and measures to complete the task, so that the organizer can achieve the expected goals more accurately, more complete, and more rationally. The tower crane(tower crane), as the main lifting equipment for building heavy objects, should be managed by special personnel. Therefore, it is indispensable for professional lifting engineers to carry out related supervision.
4, in the event of a failure in the tower, the appropriate cable should be pulled to prevent wind and accident

Tower hoist often fails due to fatigue and overwork during construction. Failure is not a terrible thing, but it can be handled with professionalism. However, safety facilities must not be small, especially to prevent dangerous situations such as rapid air flow. Therefore, wind protection measures can not be ignored.
5, should be on the ground for appropriate vigilance, not to enter the dangerous area
Since the role of the tower crane is to transport heavy objects to high altitudes, once the objects fall during the transportation process, the safety of the ground personnel will cause unimaginable results. Therefore, when the tower crane is operated, The construction and supervision party shall, in accordance with the work plan, designate a "red zone" in which no entry or exit by any person is permitted.
The hydraulic lifting mechanism shall take pressure relief measures to ensure that the tower top gravity falls on the top of the tower

The hydraulic lifting mechanism of the tower crane provides a huge lift for the lifting. Due to the liquid flow, it often causes a slight deformation of the overhead mechanism.

 Once the heart is taken lightly and the pressure discharge process is ignored, the deformation of the daily accumulation will change. The force direction of the tower machine, An accident with unpredictable consequences.
7, pay attention to the weather forecast, timely take emergency measures
During the construction of the tower, wind power and wind speed monitoring are also indispensable. In general, when the wind power is higher than the sixth grade, the tower suspension construction should be stopped to prevent accidents.

Every time you start the tower, you need to run an empty car and check the following
Because of its strong scalability and large bearing capacity, tower crane plays an increasingly important role in construction and cargo handling. However, because tower crane construction involves the risk areas such as electromechanical operation and high-altitude operations, construction safety has also become a matter that every tower crane driver must pay attention to. In this regard, before each tower crane is started,
