Mechanical Dredging Four-rope Grab Bucke Information
The four-rope clamshell grab is an effective tool for loading and unloading bulk cargoes such as yellow sand, coal, mineral powder, cement, and bulk chemical fertilizers under various harsh environments. The grab structure is simple, the failure rate is low, the operation is convenient, and the opening and closing motion can be accurately completed under various conditions. Grab adopts three-dimensional virtual design and uses ANSYS for strength verification and analysis. The weight distribution is more reasonable and the service life is longer. After years of accumulation, our company has formed a series of hundreds of types of grabs ranging from 1t to 100t, which is the first in the same industry in China. Grabs are suitable for loading and unloading all kinds of bulk cargo with double-reel cranes and can be applied to cranes with various pulley arrangements. There are often six types according to the arrangement of the pulleys and the connection to the crane.
