The AZF drive:

─     The drives are designed as pole-variable rotary current motors with electromagnetic spring-loaded brakes and gear units.

─     The drives have a low and a high speed. The ratio of the two speeds is 1:4.

─     The drives have a modular construction of motor and gear unit to enable easy replacement.

─     Using plug-in connections in the connector housing directly on the drive, the drives can be quickly separated from the rest of the crane’s electrics.

─     The drive's gear unit is a maintenance-free, flat gear unit with friction clutch.

─     Two drives are used for crane travel on a crane. One or two drives are used for trolley travel on a trolley.

─     The crane can also be equipped with four crane drives (4-wheel crane travel drive, all-wheel. Optional). This is required whenever the crane travel drive needs to be particularly sturdy (e.g. for operation outdoors with a headwind, or travelling through curtains).

─     The drives of the size V420 and V500 have a visible output shaft.

─     The drives are equipped with a fan blade on the motor shaft for ventilation. For very slow travel speeds, the drives can also be equipped with auxiliary fans.
