The AZP and E drives:
─ The drives have a low and a high speed. The ratio of the two speeds is 1:4.
─ The drive's gear unit is a maintenance-free, two-stage or three-stage planetary gear.
─ 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).
