Ce Certificate 20 Ton Four Rope Clamshell Mechanical Grab For Coal Bulk Carrier Grab Bucket
Product Description:
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.
Product advantages:
1. Close automatically on the materials and open at any position without external power;
2. 100 m distance remote control from the grab.
3. Using 3D Virtual Design to secure outward appearance, grabs can be customized;
4. Main components of hydraulic system imported from Europe, so multistep buffering open style to keep longer service life.

Crane grab application:
According on the material type and customer requirement to design grab
with teeth, parallel girder with open, underwater operation and so on form.
Crane grab working duty:
Because the bucket size is different, so the volume of the grab also different.
According on the material density and volume, we design four type working duty grab bucket,
such as light duty, medium duty, heavy duty and overload duty.
1) Light: suitable for grasp all kinds of coal and pulverized coal, coal ash powder hydrated lime, blast furnace slag, etc;
2) Medium: suitable for hold the manganese ore, copper concentrate, zinc concentrate, iron, lead, zinc clinker,
slag and sand, limestone, gravel, etc.;
3) Heavy: suitable for hold the iron ore, dolomite, magnesite, copper, lead concentrate, massive slaked lime, etc.
