Sandvik upgrade mobile crusher range

Radical and innovative design changes to new models: QJ241, QJ341, QJ331 and QH331

FOLLOWING the combustion engine exhaust gas legislation for Europe and the US, which came into force in January 2011, Sandvik have upgraded their QJ340, QJ240, QJ330 and QH330 mobile crushers to QJ341, QJ241, QJ331 and QH331 respectively.

The new models will incorporate a new engine compartment to house either Stage 3A/Tier 3 or Stage 3B/Tier 4i Caterpillar engines, depending on the destination legislation.

Sandvik say the introduction of the new emission-compliant power pack and redesigned engine compartment coincides with a number of other radical and innovative design changes to enhance performance and serviceability.
Among the operational upgrades, the new models will feature:

  • A new Danfoss hydraulic and electrical control system for greater efficiency.
  • Full PLC control system and colour screen allowing visual data output and control.
  • Hydraulically driven cooling fan with auto-reverse to back-flush dust from the radiator.
  • Proportional control for machine tracking.
  • Hydraulic raising and lowering of the main conveyor on the jaw crushers to give increased clearance for rebar discharge in recycling applications.
  • New direct drive on the QH331 for enhanced operational capabilities.

In addition, Sandvik say customers will benefit from improved maintenance features, including:

  • Steel pipework, for a maintenance-free sealing solution and better heat dissipation.
  • Improved service points: both sides of the engine enclosure are accessible.
  • All engine service points are easily accessible with low-level drain points.
  • All hydraulic valves are now situated at ground level for ease of access.
  • Diesel tanks and smaller hydraulic tanks featuring inspection covers are easily accessible from the front platform on the machine.
