A clean solution

Heavy duty pneumatic tyres PS 430/30-90K and flanged wheels SPK 250K

The customer

… is Austria-based manufacturer of vehicles and machinery used for urban hygiene, with a focus on street cleaning and sewer cleaning. The company was established over 50 years ago and currently employs around 50 people. Its product range includes road sweepers with capacities of between 1 - 12 m³, street washers, special equipment like rail groove cleaners and a wide range of specialised accessories.

The application

Many of the sweepers provided by the vehicle and machinery manufacturer are fitted with Blickle wheels and castors. One particularly interesting item is a specially developed rail groove cleaning device which can be attached directly behind any vehicle with a trailer coupling and an existing pneumatic, hydraulic and water system. The attachment was designed specifically for cleaning along tramway tracks, and is already in use in a number of cities across the world, including Stuttgart, Saarbrücken, Riga and Doha/Qatar. The device is lowered onto the rails using a pneumatic system. The trolley of the rail groove cleaner uses four Blickle SPK 250K flanged wheels with ball bearings. With two running wheels which can be pneumatically extended and retracted (Blickle PS series heavy duty pneumatic wheels), the system is guaranteed to run at speeds of up to 25 km/h.

Our solution from the standard range

The two PS series running wheels with a wheel diameter of 420 mm are perfectly suited for outdoor applications. They are particularly good at preserving floors and reducing noise levels, while also being resistant to a wide range of aggressive substances. The PS 430/30-90K heavy duty pneumatic wheels provide a load capacity of 500 kg at a speed of 25 km/h. As this application does not make full use of the load capacity on offer, the customer has stated (at its own risk) that the system is capable of operating at speeds of up to 40 km/h. The extremely wear-resistant SPK 250K flanged wheels, made from robust grey cast iron, keep the system secure and stable on the rails. The cast wheels have a low rolling resistance and can resist temperatures of up to 120 °C. Considering the heat which can be generated by the friction with the rails, this is a significant advantage.

The result

The cleaning machine manufacturer can use a single supplier for all of the wheels and castors which they need. Outstanding Blickle quality and quick delivery times are guaranteed, reducing administrative costs and expenses related to complaints and returns to a minimum.
