Precautions related to the use of cranes

Cranes have brought great efficiency, convenience and speed in production, but due to the unsafe factors of machinery, the influence of on-site use environment and frequency, frequent failures occur. This paper mainly analyses the common mechanical failures of cranes in order to reduce their maintenance times and achieve practical benefits.

A crane is a lifting device that is horizontally placed over workshops, warehouses and stockyards for material hoisting. Because its two ends sit on tall concrete columns or metal supports, it is shaped like a bridge. The bridge frame of the crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is the most widely used and has the largest number of hoisting machines.

The operating environment of cranes is usually complex, so the operating loss in these environments will be relatively large, which will lead to some problems and failures, reducing the service life of the crane.

The first is the impact of the size and nature of the working load on the crane. In daily operations, when the load on the parts is greater than the average design load, it will often lead to increased wear and tear, and long-term high-load operation will reduce the service life of the crane. After a lot of practice, it has been proved that stable load has less wear, less failure and longer life than dynamic load.

Secondly, the working environment is also a common factor affecting the performance of cranes. Working in places with a lot of dust and metal impurities will greatly reduce the service life. Because of working in this environment, some impurities have entered the interior of the machine, resulting in an increase in wear and tear, an increase in the failure rate over time, and a decrease in performance. In addition to this, the humid environment and the nature of the work are also important factors. Therefore, it is very necessary to do maintenance work at ordinary times, such as the use of lubricating oil, blocking harmful impurities, reducing wear and tear, cleaning of the on-site environment, etc.

When the crane is in use, the moving parts will inevitably be worn, the connectors will be loose, the oil will be deteriorated, and the metal structure will be corroded, which will cause the technical performance, economic performance and safety performance of the crane to be reduced to varying degrees. Therefore, in order to prevent and eliminate hidden dangers and ensure that the crane is always in good condition, the crane should be maintained before the wear and tear of the crane parts have reached the level of affecting the crane to fail. Through the maintenance of the crane, the repair interval of the crane or mechanism can be effectively extended, including the overhaul period, to prevent unnecessary downtime accidents, thereby prolonging the service life of the crane.

Generally speaking, a crane is relatively stable mechanical equipment, but it is also easily affected by external factors during its operation, including some impurities. These impurities may have a fatal impact on the crane, so it is very necessary to take some relevant precautions.

Because lifting machinery is a kind of space transportation equipment, its main function is to complete the displacement of heavy objects. It can reduce labour intensity and improve labor productivity. Hoisting machinery is an indispensable part of modern production, and some hoisting machinery can also perform some special technological operations in the production process so that the production process can be mechanised and automated.

After all, cranes are indispensable tools in construction and industrial production. We can see them everywhere on construction sites. The crane itself has a huge structure, a complex mechanism, various heavy liftings, and a complex environment. The accidents that lead to crashes have their own characteristics. The crane safety device should be strengthened, and the crane accident characteristics and the function of the safety device should be understood to ensure safe use.
