The L0VR “EBox” is a flameproof-protected enclosure combining both hydraulic and electronic components into a single, compact manifold for control and monitoring of a complete roof drilling rig. The manifold attaches directly to the hydraulic porting interface of the drill rig. This does away with up to thirty hydraulic hoses – normally required when an external control manifold must be connected to a drill. These drilling rigs are typically mounted on mobile underground mining equipment for drilling roof holes and for placing roof-supporting bolts.

Internally, the E-Box features a microprocessor-based circuit board to proportionally control a number of solenoid-actuated hydraulic valves (also mounted inside the E-Box manifold). The electronic module monitors the spool position of key hydraulic valves and hydraulic pressure of secondary functions to establish if hydraulic outputs are responding to control inputs and to detect any unplanned operation. Real-time monitoring of hydraulic oil flow to the drilling feed function is used to establish drilling feed speed and depth.

A host control system controls and monitors the E-Box operation via an industry-standard CAN field bus connection.
