Grabs for Extreme Requirements

For more than 50 years, KRÖGER grabs from METZEN have stood for precise, robust and low maintenance lifting solutions in industrial applications. Whether in port handling, raw material extraction or thermal waste recovery, our grabs are used wherever heavy materials need to be moved safely and efficiently.

The principle is simple: maximum reliability with minimal maintenance effort. Our rope, motor and hydraulic grabs are designed to deliver consistent performance even under extreme conditions – at great depth, high operating frequency or with abrasive materials. Thanks to modular design, adaptable geometries and durable materials, our grabs can be tailored precisely to your plant, your material and your operating environment.

It is not only about lifting capacity and technology, but about smooth processes, shorter handling times and maximum availability. With KRÖGER grabs, you create the foundation for stable operations, reduced downtime and overall economic performance, regardless of the application.

Handling Technology for Ports and Logistics

In port operations, every second counts. Our KRÖGER grabs are specially developed to meet the demanding requirements of sea and inland handling, with the goal of minimising handling times and maximising utilisation. Whether for inland vessels, sea freighters or storage handling, our grab solutions ensure reliable material movement with minimal maintenance effort.

With different drive concepts – mechanical, hydraulic or electrohydraulic – and a wide variety of designs, our systems can be seamlessly integrated into your cranes and process flows. For port operators, this means smooth operations, high cost efficiency and technology that performs reliably even in continuous 24-hour operation.

Powerful Technology for Gravel, Sand and Mineral Materials

In the extraction and processing of stone, earth, gravel and sand, reliability and wear resistance are essential. Our KRÖGER underwater grabs are designed for great depths, challenging ground conditions and extreme loads, featuring rope friendly guide systems, wear resistant materials and maintenance free technology.

With adaptable teeth, lightweight construction and optimised kinematics, our grabs enable efficient bulk material handling with high conveying capacity and minimal strain on the carrier system. The result is durable solutions for demanding conveying tasks in quarries and in river or sea dredging.

Reliable Grab Solutions for Thermal Recovery and Refuse Derived Fuels

When handling waste, refuse derived fuels and slags, robustness and reliability are essential. Our KRÖGER rope and motor grabs are specifically designed for use in waste incineration plants, sewage sludge treatment and waste to energy facilities. They feature durable construction, low maintenance joints and high loading capacity.

The grabs can be easily integrated into different crane systems and ensure a consistent fuel feed even with high material throughput. In doing so, they not only secure the availability of your plant but also improve the efficiency and environmental performance of your recovery processes.
