Industrial gear units for lifting applications

Lifting applications place particular demands on the in stallation 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 industrial gear units NORD DRIVESYSTEMS 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. As for all NORD gear units, the proven principle of robust one-piece UNICASE housing will be applied. During de velopment, the MAXXDRIVE ® XD’s housing was specially designed for lifting applications and optimised for down ward loads. The elongated arrangement of gear stages also enables mechanical tailor-made dimensioning of the gear unit with sufficient centre distance – thus avoiding the otherwise all too common over-dimensioning. Standardising variants NORD currently offers the new MAXXDRIVE ® XD in five sizes with centre distances between 509 and 963 mm 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 constructing their cranes. With the three and four stage

versions, MAXXDRIVE ® XD covers a wide speed range with a maximum nominal gear ratio of i=355. The constant torque across the whole speed ratio guarantees high efficiency in use. “We are pleased to offer complete drive solutions that are economical and tailor-made and in line with NORD’s quality standards,” said Niermann. Serial components for quick delivery For the MAXXDRIVE ® XD’s components, NORD is using tried and tested standard parts from its proven range of industrial gear units. This offers customers a wide range of options and guarantees short delivery time. Additional ly, housing is available with an inspection cover, enabling a visual check of internal components without having to remove the gear unit. The units are available in grey cast iron (GJL) or nodular cast iron (GJS).

The MAXXDRIVE ® XD’s housing was designed specifically for lifting applications and optimised for downward loads.
