Metso to send six mobile jaw crushers to Japan

Shimizu Corp. taking delivery of Lokotrack LT120 units to assist in post-tsunami civil works project

METSO are currently delivering six Lokotrack mobile crushing plants to Japan to assist in a major landfill project being carried out in the 2011 tsunami area in the Tohoku region. The new-generation LT120 crushing plants will be used to crush 6–7 million tonnes of aggregates on a demanding project schedule.

The earthquake and tsunami caused significant sinking of the ground level in several coastal areas in the northern part of Honshu island. Before new construction works can begin, the ground level has to be raised by several meters using aggregates as fill material.

The Lokotrack crushing plant fleet will be operated by Shimizu Corp., specialists in post-tsunami civil works planning and execution. The LT120’s were sold to Shimizu by Metso’s Japanese distributors, UBE Machinery Co. Ltd, who will also take care of service and parts-related tasks.

‘Our new-generation Lokotrack LT120 jaw plant is a high-capacity primary unit that, depending on the feed material, is able to produce more than 400 tonnes/h of crushed material on a continuous basis. This machine is ideal for jobs requiring big production volumes,’ commented Timo Nakari, Metso’s senior vice-president of the mobile equipment business unit.

‘After 30 years of serial production and in excess of 7,000 manufactured units, Metso’s Lokotrack range, which consists of more than 25 basic models, carries a solid reputation in the market place. Through the years, Lokotrack has become a generic term for any mobile plant,’ Mr Nakari added.

The Lokotracks are being manufactured at Metso’s crusher works in Tampere, Finland, and will be delivered to Japan during spring 2015. At the sites in the Tohoku region, the LT120’s will be operated as single units, producing 0–200mm aggregates for landfill.

The Lokotrack LT120 is built around Metso’s proven C120 jaw crusher. With its 1,200mm x 870mm feed opening, the jaw can accept even large-sized boulders as feed material. The LT120 weighs 60 tonnes and is powered by a modern 314kW Cat C13 diesel motor.

All Lokotrack units delivered to Shimizu will be equipped with Metso’s new boom and hammer combination for easy and safe clearing of any blockages.
