Nord Drivesystems offers properly dimensioned drive solutions from a single source for different crane types and load ranges. The company has locations in more than 80 countries. In Poland, the lifting equipment specialist Protea relies on the crane & cargo competence of the complete supplier from Northern Germany. The Polish manufacturer Protea has been relying on drive solutions and services from Nord Drivesystems for years. The company uses Maxxdrive industrial gear units for its gantry cranes, which are also used to transport straw bales in biogas production. They cover torque ranges up to 282,000 newton meters.
For the lifting gear, Protea uses a robust 18.5 kilowatt Maxxdrive XD. These parallel gear units are based on the proven Unicase housing principle and have been specially optimized for heavy loads. Due to the elongated arrangement of the gear stages, the housing has a large center distance, which enables a U-shaped drive design. This makes it easy to locate the cable drum and motor on the same side of the gear unit, especially for hoist drives. The drives for cranes and trolleys are also based on the Maxxdrive industrial gear units with power ratings of 0.55 and 11 kilowatts.
“Our goal is to work in close coordination with our customers to find the optimum drive solution for their crane applications”, says Gernot Zarp, Sales Manager at Nord. “With our versatile product portfolio, we offer a wide range of drive components.” The drive specialist thus allows for individual system solutions, whose power, weight, size and service life are precisely tailored to the respective application. “Overdimensioning the drive is therefore no longer necessary”, says Zarp.
The company has expanded its portfolio to include additional Maxxdrive XD sizes specifically for hoist design. The industrial gear unit can now be configured with center distances of up to 1,281 millimeters. This further improves the economic and customized dimensioning of hoist drives for crane applications. The installation space is optimally used and the weight of the drive is significantly reduced. All in all, Nord offers its customers more flexibility in crane system design.
“We chose Nord components because the company is a reliable partner with whom we have been working for many years”, says Tomasz Poprawa, Project Manager at the Polish crane manufacturer Protea. “The products are of high quality and recognised throughout the world.” Poprawa appreciates the one-piece Unicase housings for their durability and low maintenance costs, as well as the double seals that ensure smooth operation without leakage.
