Terex Finlay introduce dual-powered J-1175 tracked mobile jaw crusher

Terex Finlay J-1175 dual-powered jaw crusher

The dual-powered Terex Finlay J-1175 jaw crusher offers operators the flexibility to power the plant either by mains electric connection or the on-board genset powerpack configuration. Terex Finlay say that either power option presents operators with significant power, servicing and maintenance cost savings in direct comparison to a diesel-/hydraulic-powered plant.

The plant incorporates the robust Terex JW42 high-performance electrically driven single-toggle jaw chamber and a heavy-duty VGF feeder to give optimum production in quarrying, mining, demolition and recycling applications. Additional benefits include, rapid set up time, ease of maintenance, high reduction ratio, high output capacity and advanced electronic control system.

The jaw chamber is hydrostatically driven, offering operators reversible operation for clearing blockages that may be experienced in demolition and recycling  applications. 


The hydrostatic system also provides variable chamber speed to suit given applications. Chamber CSS (closed side setting) adjustment is fully hydraulic, and can be changed in a matter of minutes.

A heavy-duty vibrating grizzly feeder with integrated pre-screen, provides an aggressive action and efficiently separates material. Material from the pre-screen can be diverted to a stock pile via the by-pass conveyor, or it may join the crushed product on the main belt. 

The large 9m³ (11.7yd³) hopper features hydraulically folding sides providing an easier working environment and faster machine set-up time. The machine also features a variable-speed and aggressive, independently driven pre-screen with automatic control to regulate the feed into the crusher as an option.

According to Terex Finlay, its quick set-up times, ease of transport and simple maintenance make the dual-powered Terex Finlay J-1175 suitable for quarrying, mining, demolition and recycling applications.

Key features:

  • Electrically driven power systems provide cost advantages and efficiencies.
  • Superior performance in dusty applications and in high altitude environments.
  • Robust high-performance hydrostatically driven single-toggle jaw chamber provides high capacity with large reduction ratios.
  • Automatic variable-speed VGF ensures continuous choke feeding of the crushing chamber for optimal productivity.
  • High powered-hydrostatic drive ensures precise chamber controls and reverse functionality for clearing blockages and assisting in demolition and recycling applications.
  • Fully hydraulic closed side setting minimizes downtime and offers quick adjustment.
