The Game Changer

The swivel circuit is fitted with two engines as standard. Dividing the high torque between two engines is a smart solution for significantly extending service life whilst reducing wear to an absolute minimum. The high torque makes working with all that power a real pleasure.

Engines with displacements of 125 cm³ (7.6 in³) or 200 cm³ (12.2 in³) are available depending on the job in hand.

A protected hydraulic system fitted with robust pipes provides the best possible protection from all known types of damage.

The GMM 50-5 features a swivel circuit with a compact design height for high charging possibility and comfortable operation. Large oil ducts with improved flow properties for a fast, powerful oil flow to achieve impressive working speeds. A sealed rotary connection and the reinforced swivel circuit, which is also sealed, highlight the quality and outstanding durability of the new GMM 50-5. This reliable, efficient grab hydraulic system makes particularly economical scrap and recycling material handling simply a matter of course in everyday working practice.

The grab features a sealed, anti-torsion piston rod guard as standard to protect from falling scrap parts, for example when dealing with bulky mixed scrap which is difficult to handle.

The hydraulic cylinders enjoy a long service life thanks to their build quality which includes the largest possible bearings for the bushing, the low wear bushings themselves and an excellent seal on the bearings to minimise wear.

A new cylinder kinematic system is used to extend the service life of the cylinder even further. Even when the tine has suffered wear it will still close effectively. Larger, high tensile screws provide the piston rod bearing with additional resistance.

A wider bearing on the solid tine bearing pin sealed on all sides eliminates the possibility of long-term wear. The combination of replaceable bushes and a newly designed pin lock reduces maintenance intervals to a rarity.

The tine bearing can be lubricated right on the pin quickly and easily. The whole process could not be easier.

Perfect tolerances of the tine cross member ensure low wear interplay between the tine and tine carrier.

The tine bearing benefits from long-lasting lubrication, lower wear and minimum friction to ensure has an unusually long service life. The increased contact area between the tine and tine carrier results in the bearing delivering an unrivalled service life.

The form and finish of the new weld connection between the inside sheet and tine body achieve a maximum service life for extreme stresses in harsh environments.

The components of the GMM 50-5 made of solid cast steel or low wear, high strength sheet steel will withstand any stress and complete any function. The strategically positioned, but also widespread use of these materials guarantees the incredible stability and resistance of the new grab in the harshest handling scenarios.

The special shapes of the tine carrier and grab tines were created using the very latest calculation and simulation software. This modern development process turns this contradiction between extreme strength and the lowest possible net weight into a harmonious whole.

Economical, efficient handling is ensured by a large number of tine versions. The perfect tine shapes and sizes are therefore available for every type of job.

The newly designed wear rib on the reverse of the cast tine significantly extends the service life of the tine. The wear rib does not however restrict the tine’s ability to penetrate into a wide variety of scrap and recycling material easily and precisely.

The special shape and alignment of the tine tips ensures long-lasting, effective penetration to ensure efficient handling of scrap and recycling material.

A new material with significantly improved hardness values gives the tine tips a pleasingly long service life.

Lubrication points are kept to a minimum and are positioned for quick and easy access to ensure the entire multi-tine grab is perfectly lubricated whilst keeping downtime to a minimum.
