Lokotrack® ST2.4™ sets a new standard in terms of set-up time. All that is required to transform the screen from transport to operating position is to unfold the conveyors, set the screen angle and raise the feeder up hydraulically.

An optimized hydraulic circuit, CAT® diesel engine, high-quality components and fabrications come as standard with the ST2.4. All of these combined increase productive time and reduce costly down time.

Screening media changes are made very easy for the operator and the unit has an excellent access way created by raising the screen hydraulically to provide a safe, easily-accessible working environment.

To meet different process requirements, such as recycling and heavy duty pre-screening, the Lokotrack ST2.4 offers a variety of different options. The apron feeder provides capacity and reliability in the most demanding quarry applications. Grizzlies, finger bars, Trellex® and a variety of steel meshes provide flexibility for tuning the process. Spare parts and service are available through Metso's worldwide network.


  • Fast set-up time
  • Excellent access for screen media change
  • Fuel efficient screening and great performance
  • Bi-Power available for external electricity

Process overview

Lokotrack ST2.4 is used as primary scalper in top soil and natural sand applications. It is suitable in multistage crushing processes to split the products eg. between the primary and secondary crusher. Depending on applications plate grizzlies, fingers, punch plates or wire meshes can be used on the top deck. Also Metso synthetic media can be applied.

How it works

Material is typically fed by the excavator. The feeder lifts material to two deck screen which then separates material to oversize and side conveyors. The unit is operated by electro-hydraulic push buttons which makes it extremely easy and safe to operate.
