Mechanical Four-rope Clamshell Bulk Grab
Mechanical Four- rope Clamshell Bulk Grab
The Scope of Application:
Four ropes clamshell grab is generally designed for handling of powder and fine bulk materials.
Product Characteristic:
The
grab catching rate is about 95%~100% , it is minimal decreasing to loose the
granularity materials when working.The bearing beam frame is shortened, Main point of liner
material for bearing steel. Prolonging the service life of the 4~5 times,and
the blade plate adopts the wear-resisting material which enhance the impact and
friction level, the pulley multi-layer seal process,dust-proof, waterproof can
underwater operations, the blade plate together gap clearance small, can
achieve 0.3mm~1mm can keep clean, the hole structure the work place have strong
shape not easily dislocation.
Product Authentication:
Approved by CCS NK ABS BV LR
