On a recent construction project in a densely populated area of Lier, between Drammen and Oslo, the company was looking for a way to reduce the cost of crushing locally sourced rocks. As Operations manager Svein-Erik Ryen explains, “Many times rocks are being extracted, driven away, and crushed somewhere else – then driven back to the same site as crushed material. We started thinking that it would make more sense to be able to crush the rocks ourselves.”
The main obstacle to doing this is that crushers are typically extremely noisy, meaning that the process must be performed a reasonable distance away from any residential areas in order to comply with environmental regulations. Not so with the Metso Lokotrack® Urban™ LT106S, which solves this issue thanks to its cutting-edge noise and dust suppression technology. This mobile crusher also comes with additional benefits that made it the perfect fit for this project and beyond.
Normally, getting the necessary permissions for crushing in an urban area is challenging due to noise restrictions. Enter the Lokotrack Urban LT106S. “This machine is quite special when compared to our previous machine. It has the latest motor technology, and it's noise and dust suppressed, which is very important for us in getting crushing permissions in the area where we are operating,” Ryen points out.
A more efficient way to crush
The LT106S uses noise covers and an internal water spraying system, which provide unique noise and dust suppression across several points, including the main conveyor beneath the crushing mechanism. Combined with the fact that it could be easily transported and used on the construction site, this made the whole process much more efficient, offering significant savings on transportation costs and time as well as being better for the environment.
