The Lokotrack EC crushing equipment range from Metso uses diesel-electric power, with all process functions powered electrically to reduce the use of hydraulic oil needed in crushing operations.
Two machines in the Lokotrack EC range have been introduced. The LT400J is a 68-ton mobile jaw crusher designed for primary crushing of hard rock and recycled aggregates. The LT350C is a 50-ton mobile cone crusher for secondary and tertiary crushing. The LT400J is equipped with the Nordberg C120 jaw crusher, while the LT350C features the new HP350E cone crusher.
Both machines can be combined with one another, as well as Lokotrack mobile screens, to produce high-quality aggregates.
"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," said Jarmo Vuorenpää, Director, New Lokotrack Offering at Metso.
The Lokotrack EC range uses new modular architecture which cuts down on the number of components and provides scalable solutions that can be adapted for different applications and capacities.
"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," said Renaud Lapointe, Senior Vice President of Metso Products business line in the Aggregates business area.
Components of the new EC range are designed and tested to perform in demanding conditions to reach maximum uptime. Safety and ease of use have been integrated into the new machines; both meet safety standards, and with new digital tools can be run from the excavator. They are also quick to set from transport to operation.
