Lokotrack® ST2.8™ & ST2.8E™ mobile scalping screen can be set-up in minutes

Lokotrack® ST2.8™ & ST2.8E™ mobile scalping screen is often used as primary scalper in top soil and natural sand applications. It is suitable in multistage crushing processes to split the products between secondary and primary crusher.

The scalping screen is fed by the excavator, wheel loader or conveyor. The feeder lifts the material to two-deck screen which then separates material to oversize and side conveyors. With two-way split option the top and bottom deck material can be combined to the oversize conveyor (fines removal).

Fast set-up time

Lokotrack® ST2.8™ & ST2.8E™ mobile scalping screen is ready for screening in minutes thanks to hydraulically operated conveyors and screen including a patent pending feeder mechanism. It is also lighter than similar machines making the transportation easier.

Biggest throw on the market

The stickier the feed material, the more throw needed in the scalping screen. Lokotrack® ST2.8™ & ST2.8E™ has the biggest eccentric throw on the market to make it the best unit for the screening of top soil, demolition waste and river gravel.

Additionally, ST2.8™ & ST2.8E™ can be fine-tuned even for sand applications. The clearance under the screen has been increased by 20% and the bottom deck area made larger as well.

ST2.8E™ powered by electricity

The Lokotrack® ST2.8E™ is equipped with e-Power that gives you twice the choice for your business. Plug it to the grid for quiet, emission-free and economical scalping in the cities, and enjoy the flexibility of modern low-emission and low noise diesel engine out in the wild.

70% less hydraulic oil with 20% more power

We have significantly reduced the volume of hydraulic oil together with introducing the new, low emission Stage V engine. The lower hydraulic oil volume is achieved by the renewed design of the hydraulic oil tank and oil circulation. This means that you can use less oil but keep the same maintenance interval. With separate pumps for screen and conveyors there is even 20% more power compared to previous models. Great improvements towards more sustainable screening!

Easy to operate

The fuel-efficient scalping process can be started with safe push buttons or by the optional Metso IC™ process control system.

In multi-stage crushing processes, the removal of fines is easy with a two-way split option. This feature combines material flow from the first and second deck to the main conveyor and maximizes the capacity and efficiency of the crushing process.

Optimum crushing results

The Metso IC™ process control system optimizes crushing results. It allows one-button start and stop, with built-in troubleshooting and a variety of parameter selections. All Lokotrack® mobile crushers in the same crushing process can be connected to the Metso IC™ system. In addition, the entire process can be conveniently monitored and controlled from the excavator's cab using the Metso Remote IC application for remote process control.
