TAKE THE TRAM!
The tram is the way to easier and cleaner everyday living. Ten purpose-built bridges and seven structures renovated for safe and smooth transport will soon enable 19 brand-new tramcars to glide along 15 kilometres of gleaming heavy-metal tramlines. Four years of construction work have kept section 1 of the Tampere tramway right on schedule ready
JACK-UP GEARS ARE MONSTERS IN SIZE AND GREAT IN SUSTAINABLE ENERGY SOLUTIONS
Jack-up platforms have long been the most popular mobile solution in marine operations. Jack-up rigs are used as exploratory drilling platforms and increasingly in connection with offshore wind turbine installation. Consisting of a buoyant hull fitted with a number of movable legs capable of raising the hull above the surface of the sea, a jack-up
THE WORLD’S FIRST LNG-FUELLED OFFSHORE CONSTRUCTION VESSEL BUILT FOR DEME IS POWERED BY WÄRTSILÄ WITH HELP FROM ATA
For the Orion, reliability is everything, and everything is at the biggest end of the scale. To give an idea of the size of the mega-calibre equipment involved, the main propulsion system has a capacity of 5,000kW per unit, the diameter of the propellers is between 3.2 and 3.9 m, and the bevel gears are

BEVEL GEAR QUALITY IS NOT GUESSWORK
The best raw materials, state-of-the-art design, engineering tools and know-how, in-house heat treatment, fine-machining and super-finishing: That’s what’s behind all ATA Gears’ solutions and deliveries. But even that is not all. You could almost say that it takes just about as many quality factors to make a bevel gear as that gear has teeth. A
CASE HARDENING – THE HEAT IS ON
Gears are expected to function reliably for years or even decades under extreme loads, so case hardening is one of the key development areas in this specific field of mechanical power transmission. That’s why ATA’s Gear Doctors are ceaselessly researching heat treatment and material science. Water jet cutting, sample cutting, grinding and polishing, adding to
WHEN THE GOING GETS TOUGH, THE TOUGH GET GOING
As the Gear Doctors of ATA, we are steadfast in using one facility to put innovation to a continuous test. A joint venture between ATA and Tampere University, the Test Bench involves testing the endurance of bevel gears in a special bevel gear endurance test rig. It is definitely a tough place for bevel gears. The loads
