Industrial gear unit from Nord for lifting gear of all kinds

Lifting applications place special demands on the installation space for drives. With MAXXDRIVE XD, Nord Drivesystems has developed an industrial gear unit with increased centre distance that is ideally suited to the U-shaped configuration of drive, motor and cable drum.

With the new MAXXDRIVE XD, Nord says it is closing a gap in its portfolio. “We can now offer our customers the complete package of running gear and lifting gear drives for cranes from a single source,” said Jörg Niermann, head of marketing at Nord.

During development, the MAXXDRIVE XD’s housing was specially designed for lifting applications and optimised for downward loads. The elongated arrangement of gear stages also enables a mechanical tailor-made dimensioning of the gear unit with sufficient centre distance – thereby avoiding an otherwise all too common over-dimensioning.

Nord currently offers the new MAXXDRIVE XD in five sizes with centre distances between 509 and 963 millimetres, and in versions with three or four gear stages. Housing dimensions and centre distance are identical for the three- and four-axle versions. This enables customers to standardise and reduce versions when construction their cranes.

Thanks to the three and four stage version, MAXXDRIVE XD covers very wide speed range with a maximum nominal gear ratio of i=355. The constant torque across the whole speed ratio guarantees a high efficiency while in use.
