Terex Finlay 863 tracked mobile heavy-duty screener

New versatile machine designed for working in quarrying, construction and recycling environments where space is a premium

The new Terex Finlay 863 is a highly versatile and adaptable machine engineered and built for working in quarrying, mining, construction and demolition debris, topsoil, recycling, sand, gravel, coal and aggregate applications where site space is at a premium.

The aggressive forward-facing inclined modular configuration screen box has a 2,755mm x 1,200mm (9ft x 4ft) top deck and a 2,755mm x 1,200mm (9ft x 4ft) bottom deck. Depending on the working application of the machine, the screen box angle can be adjusted hydraulically between 14–18 degrees. The top deck can be fitted with a variety of screening media including: tines, bofor bars, punched plate and mesh. The bottom deck can be fitted with mesh or cascade fingers.

A high-performance 1,000mm (40ft) four-ply belt feeder, with hydraulic gearbox drive, is fitted to the machine as standard and has proven performance and versatility in demanding and varied working environments. The hopper has a 5m³ (6.54yd³) capacity as standard.

The machine is equipped with three hydraulically folding discharge conveyors allowing for maximum stockpiling capacity and the associated benefits of rapid set-up and tear-down times.

A Deutz 2011 49kW (66hp) air-cooled engine powers the machine. The heavy-duty crawler tracks, and optional radio remote control unit, make on-site mobility very easy.

An additional key feature of the machine is hydraulic raising of the discharge end of the screen box to provide additional clearance for screen box and fines transfer conveyor maintenance.

The plant has the capacity to process at a rate of up to 250 tonnes/h and can be fed either by a tracked mobile crusher or an excavator.

The fully self-contained plant can be hydraulically folded and ready for transport in less than 30 minutes making it suitable for contract screening.

Key features:

  • Aggressive screen box can accept bofor bars, screen harps, woven mesh, punch plate and cascade fingers.
  • Screen box angle can be hydraulically adjusted between 14-18 degrees.
  • Screen box discharge end can be hydraulically raised 500mm to facilitate efficient and easy media access and changing.
  • Oversize conveyor angle can be hydraulically adjusted from 15 degrees to 24 degrees.
  • Optional raised chassis for extra ground clearance and additional stockpile height.
