en.Wedoany.com Reported - Germany Liebherr has launched a series of tooling solutions for extreme working conditions in the waste treatment and recycling sector, including clamshell grabs, multi-jaw grabs, lifting magnets, and fully automatic quick-change systems. These tools must handle both heavy, sharp large steel scrap and lightweight mixed waste, ensuring safe and efficient handling, precise sorting, and rapid loading and unloading while maintaining high process reliability.
Liebherr's multifunctional solutions are designed to efficiently handle various materials such as grabbing, sorting, separating, feeding, or loading, while maintaining the highest process reliability. From clamshell grabs and multi-jaw grabs to lifting magnets and quick-change systems for safe and rapid tool replacement, each solution is tailored to enhance productivity, flexibility, and operational efficiency, adapting to more application scenarios and enabling modern material handling equipment to reach its full potential.
The Liebherr GMZ 40 clamshell grab, equipped with a bulk material bucket, is specifically designed for efficient handling of bulk materials such as metal chips, fine scrap, and granular materials, with a capacity of 4.50 m³, enabling fast and reliable loading and unloading of transport vehicles. This grab features large streamlined oil passages and a high-performance rotary motor for fast cycle times, while its robust design and spiral steel hose protection ensure long-term durability in demanding applications. An optional central lubrication system, operated via pump or carrier machine, further simplifies maintenance. The clamshell grab is available in various bucket shapes and sizes to meet different handling needs.
The Liebherr GMM 35-5 multi-jaw grab, an upgraded model of the GM 65, is designed for steel scrap, metals, and bulky materials such as waste wood and tires, achieving optimal penetration and secure gripping. It is equipped with two powerful rotary motors providing extremely high torque, with modular interchangeable motor options available. Standard features include stroke-end cylinder cushioning, anti-rotation sealed piston rod guards, and durable solid housing bearings to enhance reliability and service life. Three optional central lubrication systems further reduce maintenance needs. The GMM 35-5 is available in four-jaw and five-jaw configurations, with open, semi-enclosed, or enclosed heart-shaped jaw designs to match different equipment sizes and material characteristics.
Liebherr lifting magnets are specifically designed for safe and efficient handling of large steel plates, chips, ingots, and steel or cast iron scrap, and support precise separation of magnetic and non-magnetic materials. High-performance magnets ensure reliable handling under demanding operating conditions, with a solid cast steel housing providing exceptional strength and durability, and high-strength wear plates enhancing impact and abrasion resistance. A universal interface allows the lifting magnet to be paired with various mounting options and rotary actuators, ensuring maximum flexibility.
The MH 40C Solidlink fully automatic quick-change system enables tool replacement within seconds directly from the operator's cab, automatically connecting or disconnecting all hydraulic and electrical connections during the coupling process. Internal system components are easily accessible and protected against rain and moisture, while carefully arranged cables and hoses help extend service life. A mechanical locking mechanism integrated into the hydraulic cylinder provides an additional level of safety, and BG Bau certification independently confirms the system's safety standards.
