Liebherr presents new multitine grab

Liebherr, a European-based conglomerate that makes construction and scrap handling equipment, has launched the multitine grab GMM 50-5. 

According to a news release from Liebherr, the multitine grab excels in terms of exceptional load-bearing capacity, resistance and durability.  The equipment features a comprehensive portfolio of buckets and a wide selection of optional equipment, meaning diverse materials can be handled efficiently and economically in recycling and scrap handling. The GMM 50-5 is available for material handlers with an operating weight of between 35-55 metric tons.   

The components of the GMM 50-5 are made of sturdy cast steel as well as low-wear, high-strength steel sheets. The consistent use of high-quality materials guarantees extreme stability and resistance for the toughest applications and material handling scenarios. The special shape of the tine support and the buckets was developed based on state-of-the-art calculation and simulation software.   

The company says it paid special attention to maximizing service life in the design phase. To split the high torque, the slewing drive, for example, was equipped as standard with two motors. Both rotary transmission and the reinforced slewing drive are sealed multiple times to give maximum protection against external factors such as dust and water.   

Large and flow-optimized oil ducts ensure fast work speeds and efficient machine operation. The sealed, anti-twist piston rod protection for hydraulic cylinders is also included with the grab as standard. The latter comes with new cylinder kinematics, which guarantees a long-lasting and good closing mechanism when the tines become worn.   

As the lubrication points are arranged ergonomically, the GMM 50-5 is supplied with the lubrication in a short space of time. Perfect tolerances and generously dimensioned bearing surfaces lead to a smooth interplay of the individual components, according to the company.  

Due to the optional motor and hose protection, damage to rotary motors and hydraulic lines is minimized. An optional central lubrication system assumes regular, automatic lubrication of all central points. The GMM 50-5 can be equipped with shackles to protect magnetic plates. The tines can be equipped with a reinforcement set of wear-resistant sheets.   

The GMM 50-5 is designed especially for optimal grabbing of mixed and shredder waste as well as chippings or shavings with content of up to 1.10 cubic meters. The arrangement and shape of the tines are optimized for perfect penetration and holding of bulky, loose material.   

There is a choice of three different tines for handling diverse materials. The version with open tines can handle large-size and bulky scrap objects. The version with semiclosed tines handles medium-sized, mixed materials and shredding waste. Small, fine materials and chippings or shavings can be handled most effectively with closed, heart-shaped tines.
