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.

Ideal for use in refuse-derived fuel (RDF) incineration plants for the handling of materials such as wood chips, shredded plastic or tires, paper and cardboard scraps, pellets and/or fluff. Mainly used in cement, paper and industrial plants (high heat-value areas). Technical design Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Both motor grab systems (MZG and MMGM) can be made fully automatic by attaching sensors MZG is ideal for use in tight spaces Lightweight design for high load capacity Size, measurements and grab suspension can be customised according to your needs Further advantages: see type MZG port and type MMGM (under “products/motor grab systems) Grab drive Vertical electrohydraulic drive unit with high-pressure pump Turn control or valve control

Bulk handling of any kind in sea and inland ports or storage facilities. The compact alternative to the MZG type grab 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 grab under the ship’s gangway Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Self-locking grab suspension for crane hooks Grab drive: Horizontal 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 shells: Material: S355J2+N Grab connection bearing: re-greaseable, robust steel bushing bearing Small grab dimensions thanks

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:

Gravel extraction: KROGER grabs dredgers and rope extravators allow you to extract gravel and sand from rivers or lakes and have been used for this purpose in the toughest conditions across Europe for over 50 years. Thanks to our maintenance-free underwater motor and ropemechanical grab systems, you can extract gravel and sand in new locations whilst complying with environmental regulations and increasing your profitability. Our grabs are particularly suitable for use on difficult terrain and at extreme depths. Our latest record also bears witness to this: our experience paid off when KROGER grab became the European champion with a dredging depth of 177 meters during excavation in Lake Lucerne. Reliability matters – even when extracting gravel and sand at new depths.
