Hot!!! China Top Mechanical and Hydraulic Grapple

Crane grab main technical parameter:

1.Rated load capacity: 3.2t~63.0t

2.Grab volume:0.2m3t~60m3

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.

Crane grab maintenance item:

1.When using, first take the grab on the fixed block grab can open and close freely;
