The company revealed the first two models of new machine range at a special ‘Lokolaunch’ event in Tampere, Finland, displaying the Lokotrack LT400J and Lokotrack LT350C models, which can be powered by external electricity and offer reduced hyrdaulic oil usage.

While the Lokotrack LT400J, which features a C120 jaw crusher, is a 68-tonne mobile unit designed for the primary crushing of hard rock and recycled aggregates, the Lokotrack LT350C cone crusher for secondary and tertiary crushing weighs 50 t and features Metso’s new Nordberg HP350e cone crusher.

According to the manufacturer, both units can be combined with each other, as well as with the Lokotrack mobile screens to produce high quality aggregates.

Jarmo Vuorenpää, Director, New Lokotrack Offering at Metso, said: “When external electricity is available, the new electric power transmission provides high capacity with minimized operational cost and CO2 emissions. When not available, the onboard diesel gensets allow maximum independent operation time.

“Also, auxiliary units, such as mobile screens and stackers, can be powered from the same gensets, which will further reduce the needed power to run the complete plant.”

Metso developed the Lokotrack EC range using what it describes as “new, modular architecture, which reduces the number of components and provides scalable solutions that can be adapted for different applications and capacities.”

Renaud Lapointe, Senior Vice President of Metso Products business line in the Aggregates business area, said: “The new way to do product development enables a faster and more agile way to meet the changing customer needs.

“Furthermore, it enables more efficient support for the machines with less parts needed and easier upgrades of new features.”
