Industrial Use Hydraulic Grab Bucket Clamshell Grab
Brief Introduction
Industrial Use Hydraulic Grab Bucket Clamshell Grab include
four-petal grabs, six-petal grabs, eight-petal grabs, and there are
five types, which are single rope, double rope, four rope, motor,
and hydraulic.
Clamshell grab is suitable for materials with harsh environment,
irregular and difficult handling materials. Such as garbage, ore,
scrap steel, aluminum ingots, limestone, gravel and other materials
for loading and unloading and transfer. The grab has been widely
used in dumps, scrap yards, ports, mines, railways. (Motor grab
cannot be launched in water)

Main Features
1) Simple structure ,easy installation and maintainance.
2) Adopting advanced world famous brand components in electric
parts and operation parts.
3) with the great abrasive resistance, high strength and can grab
the material very well.
4) Running in a high authorization and internationalization,no
pollution.
5) Widely used in Wharf, steel mills, power plants, ships, etc.
Crane grab maintenance
1.When using, first take the grab on the fixed block grab can open
and close freely;
2.Check the oil hole parts and the butter is filled;
3.check whether the connection parts slacken, or loose, must first
tight;
4.adjust the wire rope before operation, the balance of grab in a
free state;
Grab bucket coiling schemes:
There are two sets of reel in the bridge crane, each group of the two wire rope tied on opposite sides of the grab bucket balance frame inclined shell or (wire loop with a cord round), as a support for steel rope. Another group of two root for opening and closing steel rope, they respectively through the rope wheel, the head pulley, beam under the pulley block and tackle formation, the opening of
the grab bucket effect.
