‘Snow-how’: Finns develop autonomous snow removal vehicles

Robotic vacuum cleaners and lawnmowers are already reality, but can the same idea be applied to a 7-ton machine clearing snow from an airstrip?

To show it can, Valtra and Nokian Tyres partnered up with three other Finnish companies in March 2019 for a joint proof-of-concept project at the European Union’s northernmost airport.

Two Valtra T254 Versu equipped with Nokian Hakkapeliitta TRI tyres and each pulling a 4.5 m wide sweeper blower autonomously cleared the runway at Ivalo airport in Finnish Lapland.

Winters in Finland can be very long, with many parts of the country covered permanently in snow for 150 and up to 200 days a year.

“As an airport operator we need to create summer conditions on Finnish runways even if it’s the middle of the winter,” said Henri Hansson, Technical Director of Finavia, the organisation responsible for maintaining the majority of Finnish airports.

“To meet this challenge, we are constantly searching for new solutions that support our world-class snow-how.”

This is how the idea for the project ‘Runway Snowbot’ was born between a group of Finnish top experts, each specialists in their own field, and each with a deep understanding of Nordic climatic conditions: Valtra, Nokian Tyres, airport sweeper blower manufacturer Vammas (Fortbrand), the energy company Neste and Finavia.

 “Runway Snowbot is a proof of concept, showing that by combining the know-how of five Finnish companies, airport runways can be cleared in a new way – more safely, more sustainably, more economically and more comfortably,” said Matti Tiitinen, Senior Brand Business Manager, Valtra Scandinavia, Baltics & Western and Central Europe.

Tractor specialist Valtra has been working on auto-guided tractors for several years. Together with Nokian Tyres, both brands set the speed record for unmanned snow-ploughing in 2018 with an autonomous T254 Versu equipped with Nokian Hakkapeliitta TRI tyres.

For project ‘Runway Snowbot’ Valtra SmartTouch features such as auto-guidance with centimetre-level precision, Isobus implement control provided the technology needed for the controlled clearing of pre-defined routes.

With Nokian Hakkapeliitta TRI tyres, the world’s first tractor winter tyre, the autonomous snow-clearing project has got the grip and accuracy needed for safe driverless tractor operation – while also being gentle to the tarmac.

“Without the driver carrying out instinctive corrections for steering and throttle, the tyres must offer very predictable handling,” said Toni Silfverberg, Head of Sales and Marketing, Nokian Heavy Tyres Ltd.

“What’s more, the operation without studs, the low rolling resistance of Nokian Hakkapeliitta TRI and our sustainable manufacturing process all add to the overall economy and sustainability.”

Both the Valtra and the Vammas sweeper blower were fuelled with Neste MY Renewable Diesel which reduces greenhouse gas emissions approximately 90% compared to fossil diesel.
