They can be combined with a long or short lantern gear drive on the output side. The mounted output pinions are manufactured according to the customer’s specifications. On the input side, we offer solutions for both electric motors and high-speed or low-speed hydraulic motors, some of which are already standardized.

One frequently requested alternative, particularly as a gear unit for slewing gear drives in bucket wheel excavators, consists of a FLENDER planetary gear unit with a bevel or bevel helical gear unit on the input side. The drive motor and a brake are arranged on a bracket on the gear unit, so that the system no longer needs to be aligned on site. A brake is always mounted between the motor and the gear unit in order to fix the boom in a defined position. An overload safety mechanism can additionally be provided on Flender gear units for cranes and slewing gears to protect the boom and the drive against inadmissibly high loads.
