Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power and other places. The tonnage selected will vary according to different use occasions. If the tonnage selected is too large, it will cause waste of equipment; The tonnage selected is too small to meet the construction needs. So in Huai'an Crane Rental It is necessary to determine the appropriate tonnage before leasing, so as to maximize the benefits.  

According to the construction experience, the selection of crane tonnage mainly depends on what goods you are lifting, and the size of crane tonnage should be selected according to needs. Therefore, careful consideration should be given to the selection of crane tonnage. below Huai'an Crane Rental Company Come and have a look!

1. When selecting the crane tonnage, it must be clear what the maximum lifting capacity is, how long the boom needs to be, the longer the boom extends, the larger the working radius (where the weight rotates from the center), and the smaller the lifting weight. For example, an 8-ton crane can lift an 8-ton weight when the boom is not fully extended, but with the extension of the boom, when the boom is 30 meters long and the working radius is about 20 meters, the lifting capacity becomes 1300 kg.  

2. It should be noted that the optimal lifting capacity of general cranes is about 90% of the maximum rated lifting capacity. When selecting a crane, try to have a certain margin. The principle of cart pulling trolley is conducive to extending the service life of the crane. Therefore, when selecting a crane, try to select a crane that is one level higher than the required tonnage.  

3. When the crane is working, remind everyone not to make the elevation angle of the boom less than 40; The lower the lifting angle of the library boom, the greater the weight the boom bears, and the easier it is to damage the boom, or even break the boom.  

The following points shall be taken into consideration when selecting the tonnage for crane operation:

1. Technical parameters of crane;

2. Weight of equipment and components;  

3. Crane operating radius;  

4. Height of equipment components.

With reference to the above hoisting conditions, select a crane of appropriate tonnage to ensure the safety of construction operations. The approximate calculation proportion of selecting a crane of appropriate tonnage for hoisting operations is about 40% of the crane tonnage.
