ST4.10™ screen operates effectively and economically
Pärhä Oy’s Lokotrack® plant specializes in high-quality production of concrete gravel.
High capacity screening
Large-scale 5'x20' 3 deck screen
Ideal for closed circuit crushing process with other Lokotrack units
Bi-Power for electric operations
On-site mobility and easy to transport between sites as a single unit.
Lokotrack® ST4.10™ mobile screen has an extensive 5' x 20' / 9 m2 screening area. It is especially designed for large-scale aggregate screening and it produces four end products.
Close circuit with extended feed box
The wide feed box and 10 m (33’) side conveyors with adjustable angles enable closed circuit production with Lokotrack mobile crushing plants or other ST mobile screens. The wide feed box also makes loading with a wheel loader easy when using ST4.10 as a stand-alone unit.
Easy maintenance with side tensioned meshes
The top and middle deck screen mesh are side tensioned and conveyors are lifted hydraulically. This means that the screening media can be changed by a single person.
Hybrid Bi-Power for electric operation
Lokotrack ST4.10 mobile screeners are powered by a CAT® 106 kW (142 hp) engine or an optional Bi-Power feature. With Bi-Power the hydraulic functions are electrically powered by plugging the screen to an external network. If a network is not available ST4.10 can be plugged to a hybrid Lokotrack mobile crusher equipped with onboard diesel generator. Operating both units with a single diesel engine is especially economically in closed circuit crushing operations. Plugging a Lokotrack crusher and ST4.10 together needs some modifications to the Lokotrack mobile crusher depending on the model.
Easy to set up and transport
Despite its large size Lokotrack ST4.10 mobile screener is fast and easy to set-up and can be transported between sites as a single unit on a low bed truck.
Process control for safety of your screen
An optional Metso IC™ process control system offers a single-button start-up and the possibility to interlock the Lokotrack® ST4.10™ with other equipment for an overall view on the process with Metso Metrics remote monitoring and data visualization service.
