Maxxdrive industrial gear units by Nord Drivesystems

Although relatively new, the MAXXDRIVE® industrial gear units from NORD DRIVESYSTEMS are among the established drive solutions for heavy-duty applications. Apart from conveying, lifting and driving, mixing and agitating are among the most important application areas. For the agitators in a non-standard biogas plant in the Netherlands, the powerful industrial gear units significantly contribute to the implementation of gas production.

MAXXDRIVE® industrial gear units from NORD DRIVESYSTEMS can be found in all industrial applications, where high performance and high ratios are required. They achieve output torques of up to 282,000 Nm and powers of up to 6,000 kW. Their torsionally rigid, one-piece UNICASE™ housing ensures a long service life as it can handle high axial and radial loads. NORD is the only manufacturer that builds industrial gear units of such dimensions and specifications with a one-piece UNICASE™ housing. Through continuous development of the series, the system manufacturer of drive solutions serves more and more industry-specific requirements, for example sizes with extended centre distance for use in lifting gear.

Powerful mixing requested An important application area is agitating and mixing, which is essential in biogas plants, for example. Only by thoroughly blending the products to be fermented, a homogeneous mass is obtained that provides optimum ambient conditions for microbes with regard to temperature, viscosity and acidity. If the microbes are active, they produce sufficient biogas. The biogas plant expansion of the Dutch Smits Groep’s large- scale agricultural unit, however, presented the designers of the mixing technology with a challenge. Contrary to standard practice, the rotating agitators had to blend a rectangular base of about 1,200 m² instead of a circular one. Another difficulty was the fact that more concrete pillars than roof girders had been placed in the towers.

ATEX-compliant and powerful The Dutch system manufacturer Jongia Mixing Technology developed a concept, where two high- performance agitators per tower ensure the biogas production. This is implemented using MAXXDRIVE® industrial gear units. Each agitator with 4.5-metre agitator shafts is driven by a NORD industrial gear unit. The application uses a total of 16 ATEX-compliant gear units with a speed ratio of 123:1, powers of 37 kW and an output torque of almost 29,000 Nm.

The biogas plant has been in operation for almost one year now. The Smits Group is satisfied. They already plan the construction of another biogas plant with eight fermenters to further increase their biogas volume.

Nagpur’s Koradi Naka to Get Y-Shaped Flyover for Safer, Smoother Traffic

To alleviate traffic congestion and enhance safety at Koradi Naka in Nagpur, a Y-shaped flyover is currently being constructed on National Highway 47. Demolition work has already commenced, with the main construction scheduled to start on June 20, 2025.The project, costing Rs 430.37 billion, involves building a 1,090-meter-long flyover that will connect Farsa, the Mahadula Railway Overbridge (ROB), and Bokhara Road, and will also feature an underpass. The existing structure will be repurposed into a service road to facilitate local traffic.Koradi Naka has been identified as a significant "blac..
