A one stop shop for mechanical power transmission products

Ringspann - Feature

RINGSPANN is a leading technology manufacturer of power transmission products such as freewheels, backstops, brakes, clamping fixtures, shaft-hub connections and overload clutches. It also leads in precision clamping fixtures and remote controls. The company has nine manufacturing facilities in Germany and across the globe.

With almost 500 employees in more than 25 countries through dedicated offices and distributing companies, RINGSPANN prides themselves on providing the latest and reliable high tech products to an abundance of customers worldwide in the field of industrial gears and geared motors, mining, machine tools, food and packaging machines, energy generation, material handling, marine, rail, aerospace, vehicle construction, pulp and paper as well as in general machine building and plant construction.

While headquartered in Germany since 1944, the company had been expanding its presence in Australia through other distributors.

It made a conscious decision to set up a dedicated Australian office in 2018 located in Melbourne and is now well-established as a leading technology manufacturer with the team there ready to service and tailor their products to suit applications and optimise solutions and will continue to service the market with a mix of existing and new products introduced every year.

Freewheels

Setting the global standard for almost 50 years, RINGSPANN freewheels of the FXM series launched in 1971 and have become a standard feature on numerous international machines and plant constructions. Precision and compact design of the internal elements is a pioneering development of the RINGSPANN design and engineering department.

They offer low maintenance “fit and forget” solutions on industrial drive trains and being equipped with the legendary “Sprag Lift-Off Type X”, they offer low lift-off speeds and wear-free continuous operation and can even be used with friction reducing solid lubricants.

The whole FXM series, comprising of more than 40 standard sizes, have race diameters from 31 to 750mm. Depending on the variant, the torque they generate can range from 110Nm to 1,230,000Nm. They do not have their own bearing support and are typically used as backstops on intermediate shafts of spur gearboxes in conveyor pulley drives or as overrunning clutches in the gearbox units of bucket elevators, automatically engaging and disengaging main and creep drives. The FXM series is continuously being redeveloped and designed to meet the demand of today’s applications.

Design and development engineers can find technical data sheets, 3D CAD models and installation instructions for all FMX Freewheels in the company’s online portal: www. ringspann.com.au.

Heavy Duty Industrial Brakes

The company is a one-stop-shop offering a comprehensive brake portfolio that includes pneumatic, electromagnetic and manual brake calipers, clamping units and accessories, as well as hydraulic and electrohydraulic braking and control systems.

Rail clamps and rail brakes are among the heavy-duty solutions in the RINGSPANN industrial brake range.

High holding forces are common when it comes to safety components in crane and excavator drive systems due to their compact design. This is particularly evident within the coal mining, steel, engineering and marine applications.

RINGSPANN’s hydraulic and electric storm brakes are considered extremely maintenance- friendly and are highly suitable for retrofit projects. Harbour cranes, gantry systems, portainers, bucket wheel excavators, steel mill cranes and large photovoltaic systems, all benefit from the stability and resistance of RINGSPANN’s storm-proof braking system products.

With a growing interest around the world by designers of conventional tower cranes for construction and rail guided systems, the installation of RINGSPANN storm-proof braking systems is becoming increasingly in demand to combat future extreme weather events. The compact design of the HR and DR series makes them an ideal solution for retrofitting older crane, conveyor and earthmoving systems.

Not only do they provide high performance for storm protection, but they also act as holding and parking brakes for the safe positioning of rail-guided crane, excavator or conveyor systems during loading and unloading processes.

RINGSPANN offers drive system engineers the appropriate hydraulic units, as well as oil sumps, seawater protective covers (for brake and power units) with optimised brake pads for both static and dynamic applications.

Biodegradable oil for the hydraulic units is also available to protect bodies of water and the soil.

Users can access the RINGSPANN developed online brake calculation tool for free simply by registering via https://www.ringspann.com.au/en. This tool allows users to determine braking torque and clamping force on a specified disc diameter, and therefore select the most suitable and efficient braking system for the application at hand.

Locking Assemblies

With a collaboration with universities coupled with decades of practical experience from key users all around the world, RINGSPANN stays committed and devoted to the ongoing further development of the frictional locking principle.

As a long-time manufacturer of locking assemblies, RINGSPANN possess a well-founded design procedure within this industry and have their own testing facility for fundamental research and quality assurance.

The results from here determine and cultivate into a well renowned and extensive line of products currently offering more than 25 shaft-hub-connection series for torque ranges from 0.16Nm to 4,225,000Nm. This product portfolio comprises of locking assemblies, shrink discs, cone clamping elements, rigid shaft couplings as well as clamping systems for mounting torque motors.

RINGSPANN’s three-part shrink discs were introduced to the successful standard series RLK603 S which are ideal for conveyor systems, stirrers, mixing plants, construction machinery and wind turbines, offering powerful externally clamping connections for the play-free connection of hollow shafts with their extremely high torque capacity across a range from 18Nm to 156,700Nm.
