Bulk handling of any kind in sea and inland ports or storage facilities. For ship-to-ship, ship-to-storage/wagon/silo handling. For various types of crane with control systems designed for hydraulic motor grab systems. Technical design Designed as a discharge and ship unloading grab with retracted pivot bearings for easy gripping under the ship’s gangway Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Grab drive: Vertical electrohydraulic drive unit with high-pressure pump Closing and opening movements are controlled through clockwise or counter clockwise rotation of the electric motor (turn control). The electric motor is only switched on whilst the closing and opening movement is being performed. Grab connection bearing: Re-greaseable steel bushing bearing Stable, torsion-resistant design using direct cylinder linkage
