 Tower Crane Knowledge sharing：

The performance and quality of the lifting mechanism directly reflect the performance of the whole machine
Tower lifting is an indispensable bulk goods handling equipment in the construction, transportation and logistics industries, and the part that makes the tower lifting up is the lifting and lifting mechanism of the tower. Its performance and quality directly reflect the performance of the tower lifting.

At the same time, it is also the most powerful mechanism in the three major mechanisms of Tower suspension, which consists mainly of motors, decelerators, brakes, and racks.
First of all, let us understand the motor part of the lifting mechanism-the type of motor used in the tower crane and the good or bad determine the lifting performance of the tower crane.

At present, the widely used lifting motors are: multi-speed motor, winding motor, frequency converter motor. Its performance and price are increased one by one, and the same type of different manufacturers produce different processes, and their quality and price vary greatly.

Immediately afterwards, it is an indispensable reducer in the tower crane parts. At present, the tower crane uses a multi-stage cylindrical gear reducer. However, due to the fierce competition in the market, the business concepts of different enterprises are different, and the production techniques used are different. Its quality and price vary greatly.

As far as I know, some gear reducers do not do heat treatment and surface treatment at all to meet the low prices of the market. As a result, the performance of the product is not guaranteed at all, the life span is greatly reduced, and there is a lot of noise soon. situation.
In addition, the reliability of the tower crane brake in the lifting mechanism also directly affects the safety performance of the tower crane. The selected manufacturers deserve attention.

The frame is similar to the metal structure of the tower crane. Its main role is to provide physical support for the lifting mechanism. Whether its structure form and material selection are reasonable is also a problem that needs attention.

The Three Principles of Selecting the Standard Festival of the Staircase Accessories
As one of the basic components of tower crane, the tower crane standard festival plays an indispensable and important role in tower crane structure. A section is connected together to form the main skeleton of the tower crane.

A good standard section can not only improve the flexibility and efficiency of the machinery, but also play a key role in avoiding the collapse of the tower crane. Therefore, the selection of the tower hanging standard festival is of great significance.
Many tower hoisting companies and second-hand tower hoisting rental companies often choose unsatisfactory standard festivals because they are not familiar with the "market". Hope to be helpful to the general public.
First of all, when selecting the standard festival for tower hoists, we should look at the security labels that have been affixed, or their own security marks that have been affixed by regular manufacturers. If not, such relatively coarse and unreliable in quality and can not withstand long-term use. So do not covet cheap, durable is the hard truth.
Secondly, when checking the sample, we should look at whether the standard section of the tower crane is smooth and delicate. If so, it is generally more sophisticated and the processing and production are relatively in place. The standard section of the tower crane is not accurate.

Third, in the near view of the standard section of the tower hanging, it should also be seen whether the connection is good, whether the joints are flexible, lubricated, if rust occurs, or the connections are relatively slow, such a standard section is best not to buy.

Because most tower hoists have limited maintenance times, and the environment where the sun is soaked in rain and salt and alkali(such as cement) corrosion is serious, the tower hoist standard festival must face many tests. Therefore, when selecting the standard festival, only careful and careful can really achieve good results.
