Swedish truck maker Scania has created the world’s largest clock with a fleet of its trucks. 14 trucks forming the three hands drove around the 750,000 square-feet (69677 square-meter) clock face for 24 hours straight.

The aim was to demonstrate Scania’s latest on-board telematics system. Marketing head Staffan Arvas said: “Trucks are huge, powerful machines, but they’re also intricately designed, refined instruments. Just like watches. Each truck had to be optimized for its specific task in the clock, and real-time monitoring and analysis through our connected services made the whole operation possible.”

A fleet of 500 horsepower (373 kilowatt) S-Series semi-trucks - recently introduced to the Scania range - and 90 drivers were used for the stunt. Those in the second hand had to drive around the clock constantly at exactly the right speed. The truck at the outer edge had to maintain a speed of exactly 53 kilometers-per-hour (33 miles-per-hour), while the innermost truck only needed to travel at 13 km/h (8 mph).

The trucks in the minute and hour hands, meanwhile, moved in an extremely precise, closely co-ordinated series of stops and starts. Sounds easy on paper, but maintaining such precise speed and timing while making a never-ending turn isn’t easy by any stretch of the imagination. Especially for the drivers in the second hand.

One of the those drivers, Elin Engstrom, said: “The most demanding challenge in long haulage is precision and punctuality. The clock was the ultimate test of staying in your line, maintaining your speed and keeping track of every second for 24 hours straight. All the drivers had to be in perfect sync and precision was the key to achieving this.”

And staving off motion sickness, no doubt.

Throughout, the trucks were monitored remotely via the telematics system, controllers keeping an eye on speed, fuel consumption and the trucks’ general health. The behind-the-scenes video below gives a good idea of just what an enormous operation the stunt was.

If only postal services were so slick.
