Single beam crane procurement considerations
A crane, also called a crane, refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. The working characteristics of single-beam cranes are intermittent motions, that is, the corresponding mechanisms such as taking, moving, and unloading in a working cycle alternate. With the development of society and the construction of cities, the development and use of cranes in the market are becoming more and more widespread.
Responding to the market demand, the more our company's business has turned out, many companies have learned about our company from various channels. Buyers don't know what products they need.
The performance of a crane is the comprehensive lifting capacity of the crane, which is determined during design and production. How many tons of cranes we usually say is a generalization of crane capacity. The capacity of a single-beam crane changes with the use time (life), the use environment, and the use state. The crane has requirements on the ground on which it is located.
The impact of wind on cranes is very large. The higher the building, the higher the corresponding crane. Usually the wind speed is getting bigger and bigger as the height increases. Often we have n’t felt it on the ground. The flag on the crane is already screaming, reflecting the difference between the altitude and the ground environment. The effect of wind causes the crane to generate wind load, and the increase in wind speed also increases the wind load to the crane. When the wind load exceeds the designed resistance capacity of the crane, a single beam crane damage accident will occur.
Due to the high risk of lifting operations, the state has designated lifting operations as special operations. Operators must obtain corresponding operating permits. At the same time, operators must be careful in daily operations and strictly implement operating procedures. Any risky operation Or negligence can bring great disaster. Therefore, the training and evaluation of operators is an important part of the safety management of single-beam cranes.
