Compact powerhouses for shredders

For recycling plants, Bosch Rexroth offers users the Hydrotrac GMR 3000 gearbox series, suitable for both mobile and stationary applications. It combines the proven advantages of Rexroth's standard gearboxes with advanced features specifically designed for the demands of high-performance shredders. With the new Hydrotrac GMR 3360 twin-tower gearbox, the company now also offers a particularly compact solution for use in shredders with two shafts.

A classic task in recycling is the shredding of components. Shredders used for this purpose must process a wide variety of materials. They often operate under partial load but must also reliably handle peak loads and blockages. Stationary plants, in particular, frequently operate around the clock and in dusty environments, requiring maximum reliability and durability.

To meet these requirements, Bosch Rexroth developed the robust Hydrotrac GMR 3000 gearbox series based on its proven standard gearboxes. Designed for mobile and stationary applications, it can be used with both hydrostatically and electrically driven shredder shafts. With output torques from 60 to 450 Nm, it is suitable for use in a wide variety of shredding machines. All nominal sizes offer flexible output options, either via a ring gear or an output shaft, and can be combined with the extensive Rexroth motor portfolio.

Overload protection in the machine's hydraulic system is achieved through a combination of specially developed valve technology and an integrated Rexroth hydraulic motor. For electrically driven shredder shafts, an optional overload module, in which the clutch is actuated and monitored by the Rexroth RC5-6/40 control unit, can provide additional protection for the machine and gearbox against total failure in the event of blockages.

Dual-tower gearbox for twin-shaft shredders

With the newly developed GMR 3360 dual-tower gearbox, users now have access to a particularly compact solution for twin-shaft shredders. The high power density is achieved for the torque range of 110 to 330 kNm in standard axle spacings and is optionally available with synchronization.

For mobile recycling solutions with undercarriages such as crushers and shredders, Bosch Rexroth also offers drive solutions with its Hydrotrac GFT series.
