Motor grab systems. A wide range of maintenance-free products Manufactured for tough yet smooth bulk load handling – in sea and inland ports, gravel and sand extraction, and waste processing – our KRÖGER motor grab systems are available in a variety of designs and all come with the KRÖGER “maintenance-free” advantage. To protect the environment and maximise your efficiency.

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

Handling general scrap, car bodies, steel chips, shredder scrap, paving stones and much more, in sea and inland ports or at storage facilities. For pier engineering and riverbed maintenance. For various types of cranes and excavators with internal or external holding cables. For various types of crane with control systems designed for hydraulic motor grab systems. Technical design Open, half-closed or closed grip design Suitable for handling scrap, stones, waste and other difficult to grab goods depending on design Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads, self-locking grab suspension for crane hooks 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:

Handling timber, stacked wood, etc., for downstream industries, in sea and inland ports or at storage facilities. For ship-to-ship, ship-to-storage/wagon/lorry handling. For various types of crane with control systems designed for hydraulic grab systems. Technical design Designed to grip stacked wood, with two interlocking shells to grip one or several logs Optimisation of crane load capacity thanks to its lightweight design which can grip maximum amounts Slim shell design for optimal penetration Wear-resistant cutting edges The hydraulic system’s dimensions, short open and close times and high closing pressure guarantee the quick grab and secure hold of the logs Protected and easily accessible inbuilt electro-hydraulic propulsion motor 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.
