Ernst Röwer’s Lokotrack is a compact and efficient recycler that is easy to move

The German company Straßen- und Tiefbaugesellschaft mbH Ernst Röwer is highlighting the key benefits of its new Metso Lokotrack® LT96™ jaw plant: compact size, efficiency, good fuel economy and easy transport. The company is well known for its professional recycling and road construction activities for nearly one hundred years in Mecklenburg-Vorpommern province.

Ernst Röwer currently recycles old, industrial buildings built during the DDR times. The Lokotrack® LT96™ jaw plant is operated at three different locations and is moved between them about four times per year.

“With its compact dimensions and weight of only 30 tons, our new unit can be moved without any extra permits. That enables us to easily transport the Lokotrack anywhere it’s needed,” comments Ulrich Nikolaus, Managing Director and owner of the company.

“We are very happy with our small, but powerful Lokotrack. We crush with it every day, year round, and the unit has proven to be very reliable with no sudden stoppages,” he adds.

Powerful recycler

Before purchasing their own mobile crushing plant, Ernst Röwer used a contract crusher to do all the jobs needed. Metso was very familiar to the company already back then because the contractor used Lokotrack equipment.

In early 2016, a decision was made to purchase their own crushing plant. A suitable LT96 with just a few operational hours was found from the rental fleet of Metso’s German distributor, Fischer-Jung GmbH.

During the first four months of operation, more than 45,000 tons of concrete blocks with rebar has been crushed. A strong magnet separates all metal pieces from the end products, sized 0-45 mm.

The clean, crushed and screened concrete is being recycled as base materials at nearby road works.

Environmentally friendly and economical

To avoid dust, Ernst Röwer uses the dust suppression system of the LT96 with high-pressure water spraying to the crusher cavity and the top of the conveyor. At the recycling plant in Penkun, water can be pumped easily from a nearby well.

After more than 1400 running hours, the LT96 has proven itself to be an economical crushing plant with low fuel consumption.

Ernst Röwer is also happy with the durability of Metso jaw wear plates. The first change of wears is planned after some 80,000 tons of crushing.

Celebrating its first 100 years in 2019

Straßen- und Tiefbaugesellschaft mbH Ernst Röwer will celebrate its first 100 years of operation in 2019. Actually, the company’s first major road project was done in Penkun in 1919. At that time, farmers were obliged to help with the materials transport, and Ernst Röwer did the blasting of big rocks and the shaping of the road.

Today, the company employs 130 people and has a total of 60 trucks in operation.
