Hydraulic 50 CBM Max Clamshell Wireless Grab Vessel
Work theory
The remote control grab controls the opening and closing of the
remote grab by opening and closing the main cylinder solenoid
valve. When the slip block slides down to the lower bolster, the
slip block is integrated with the lower bolster, and the grab can
grab the cargo. When it is necessary to open the grab, press the
remote control transmitter to control the solenoid valve to be
energized, the hydraulic system oil circuit is opened, the slip
block is separated from the lower bearing beam, and the grab is
opened to release the cargo. At the same time, the sliding block
moves up and collides with the upper bolster. After a delay, the
solenoid valve is closed to prepare for the next operation.
Closing Cycle:
When the grab is opening, the moving board is connecting with top
roof beam,and separate with down roof beam, at the that time, the
hydraulic circuit system is opening, and the piston of hydraulic
vat was pulled out by moving board, when grab the goods, the hook
of the crane go down, the moving board go down along the hydraulic
vat with the piston of the cylinder, when the moving board touch
the stroke switch on the down roof beam, the stroke switch stop the
eleclromagnetism valve to stop the hydraulic oil . The hook of the
crane goes up with moving board and down roof beam, to make the
grab close.
Opening Cycle:
Press the radio switch, send the message to the receiver, then the
electromagnetism valve open the hydraulic circuit system, the
hydraulic vat was extended because of the gravity of goods and down
roof beam, the down roof beam was separated from moving board, to
make the grab open , and the grab can do the next closing cycle.
