Liebherr’s GMM 50-5 five-tine grab is available for material handlers with an operating weight from 35 to 55 tonnes. Featuring components made of sturdy cast steel as well as low-wear, high-strength steel sheets, the grapple is designed to handle the toughest applications and material handling scenarios.

The shape of the tine support and the buckets was developed based on state-of-the-art calculation and simulation software, and both the rotary transmission and the reinforced slewing drive are sealed multiple times to give maximum protected against external factors such as dust and water. The unit can also be equipped with shackles to protect magnetic plates. In order to protect the edges of the often highly stressed internal sheet of the grab against wear and tear, the tines can be equipped with a reinforcement set of wear-resistant sheets.

The company offers a choice of three different tines for handling diverse materials: The version with open tines is perfect for handling large-size and bulky scrap objects. The version with semi-closed tines is ideal for medium-sized, mixed materials and shredding waste. Small, fine materials and chippings or shavings can be handled most effectively with the closed, heart-shaped tines.
