Assisted emergency steering for underground drills

The system consist on a hydraulic pump (supplied in 24V by the machine’s batteries), activated with a button located on the operator’s dashboard.

  • Description

    In case of failure of the diesel engine or the coupling between the engine and the tramming motor, it is very difficult to tow the unit as brakes are still applied, jacks might be on the ground and steering is very difficult (or even almost impossible) to operate with the orbitrol function.

    In order to make safer and to ease the towing procedure, Sandvik offer the possibility to equip the machine with motorized emergency steering retrofit kit.

    The system consist on a hydraulic pump (supplied in 24V by the machine’s batteries), activated with a button located on the operator’s dashboard. The operator must keep the button pressed so that the system stays activated (hold-to-run). When both emergency pump and parking brake release buttons are pushed, the electric motor of the pump unit is activated, and the pump starts to provide flow to activate the steering, lift-up the jacks and release the brake.

  • Advantages

    -Eases and make the towing operation by making steering, brake release and jack lift easier.

  • Customer values
