BECAUSE lifting applications place special demands on the installation space for drives, Nord Drive Systems has developed an industrial gear unit with increased centre distance that is ideally suited to the U-shaped configuration of drives, motors and cable drums.
The MAXXDRIVE XD’s housing was designed specifically for lifting applications and optimised for downward loads. With the new industrial gear units, the drive specialist from northern Germany 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 head of marketing at NORD, Jörg Niermann. As for all NORD gear units, the proven principle of robust one-piece UNICASE housing will be applied.
During development, the new unit’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.
Standardisation and reduction of variants
NORD currently offers the new MAXXDRIVE XD in five sizes with centre distances between 509 mm and 963 mm. There are also 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.
Thanks to the three- and four-stage versions, the new unit covers a 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. “We are delighted that we are now able to also offer complete drive solutions in an economical and tailormade manner with our proven NORD quality standards,” said Niermann.
Serial components for quick delivery
For the unit’s components, NORD is using tried and tested standard parts from its range of industrial gear units. This offers customers a wide choice of options and guarantees short delivery times.
Additionally, housing is also available with an inspection cover, enabling a visual check of internal components without having to remove the gear unit. It is available in grey cast iron (GJL) or nodular cast iron (GJS).
Industrial gear units for a wide range of applications MAXXDRIVE XD is suitable for use in lifting equipment in all kinds of cranes: From port and container cranes to overhead and gantry cranes but also for container and high bay coil storage.
This makes it relevant for a wide range of industries, not just for ports, logistics and shipyards but also for the metal, chemical and paper industries as well as for mining and bulk goods trans-shipment.
