For more than 50 years, KR\u00d6GER grabs from METZEN have stood for precise, robust and low maintenance lifting solutions in industrial applications. Whether in port handling<\/a>, raw material extraction<\/a> or thermal waste recovery<\/a>, our grabs are used wherever heavy materials need to be moved safely and efficiently.<\/p>\n 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 \u2013 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.<\/p>\n It is not only about lifting capacity and technology, but about smooth processes, shorter handling times and maximum availability. With KR\u00d6GER grabs, you create the foundation for stable operations, reduced downtime and overall economic performance, regardless of the application.<\/p>\n<\/div>\n In port operations, every second counts. Our KR\u00d6GER 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.<\/p>\n With different drive concepts \u2013 mechanical, hydraulic or electrohydraulic \u2013 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.<\/p>\n<\/div>\n In the extraction and processing of stone, earth, gravel and sand, reliability and wear resistance are essential. Our KR\u00d6GER 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.<\/p>\n 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.<\/p>\n<\/div>\n When handling waste, refuse derived fuels and slags, robustness and reliability are essential. Our KR\u00d6GER 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.<\/p>\n 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.<\/p>\n<\/div>\n Whether in material handling, raw material extraction or thermal recovery, our senior engineers support you with technical expertise, many years of experience and a deep understanding of demanding lifting processes.<\/p>\n We develop individual grab solutions precisely tailored to your requirements.
