Choosing the right grapple is very important, not only to improve efficiency and ensure the quality of work, but also to increase the life and safety of the equipment, and at the same time can reduce costs and increase the economic benefits of the company.
Enjue Grabs will help you analyze how to choose the right grab for your working conditions, the most basic can now be based on the following two aspects to choose: the type of crane and the loading and unloading of goods.
01 according to the crane to choose the power form of the grab
According to the definition of grab
The clamshell grabs as a lifting tool under the crane, so even the most advanced clamshell grab bucket cannot be separated from the crane to work independently.
On the contrary, the most advanced large tonnage ship unloader cannot be separated from the grab to have productivity. Therefore, what kind of crane should be matched with what kind of grab, if the wrong match can not be used, overloaded can not be used.
For example
The crane's lifting drum is a single drum and, if equipped with a mechanical grapple, can only be fitted with a single cable grapple. If it is equipped with a four-cable grapple, the grab bucket will not work.
02 Choose The Grab Structure According To The Type Of Cargo To Be Loaded And Unloaded
According to the definition of grab
A grab is used to load and unload different loads. So, whatever type of load is to be loaded and unloaded, it should be equipped with an appropriate grab. If it is wrong, it will be either inefficient or unusable.
For example
If the load to be loaded and unloaded is coal, a light clamshell grab bucket is used. If a heavy clamshell ore grab is used, the loading and unloading efficiency will be at least 50% lower.
For example
If the load to be loaded and unloaded is coal, a clamshell grab is used. If a toothed grab is used, it is like the Chinese saying "fetching water with a bamboo basket is a waste of effort". It cannot be used.
