Mining Equipment Camera Installation Tips for Best Results

Position and Mount the monitor so that:

  • It does not obstruct the operators view.
  • It is easy to see at a quick glance and doesn't require the operator to contort his head or body.
  • It is shielded from glare from the sun.
  • It does not obstruct the control panel or any equipment controls.
  • Its controls can be easily reached by the operator.
  • It is securely attached to either the roof or the floor of the cab.

Position the Camera(s) to:

  • Shield the camera from engine exhaust and retarder heat sinks.
  • View blind areas to see persons or objects near the vehicle in the front, sides, and rear , depending on the size of the equipment and the blind areas.
  • Assist in backing by viewing the inside edges of both rear tires on rear dumps and the ground very close to the machine.
  • Avoid duplicating mirror coverage.
  • Be protected from physical damage by utilizing heat shields, mud flaps, and machine members.
  • Be protected from sun glare by mounting the rear camera on rear dumpers up as close to the underside of the bed as possible.

Route and Protect the Wiring by:

  • Never running the wiring through access panels or their openings.
  • Putting wiring in protected location.
  • Keeping it away from hot surfaces.
  • Keeping it away from pinch points such as door jambs.
  • Following the Original Equipment Manufacturer (OEM) wiring harness bundle.
  • Tie wrapping the camera wiring harness to the OEM harness wherever possible with no more than 1 foot increments between tie wraps.
  • Avoiding routing in areas near fuel, fluids and lubricants.

Power Source Considerations:

  • Fuse the power feed to the camera system.
  • Be certain camera/monitor voltage is compatible with the power source.
  • Use a regulated power supply to prevent power surges.
  • Consult the equipment manual(s) about where to tap in for a power source.

Maintenance Suggestions:

  • Shielding the cameras from high heat sources will increase their life.
  • Silicon gel on connections will help reduce corrosion related water damage.
  • If the monitor shakes during equipment operation, add bracing to prevent circuit board fatigue and electrical failure.
  • Some mines pressure wash the cameras to clean the lenses but, excessively high water pressures may cause leakage past the lense seals.
  • Silicone gel protects speaker openings from water damage without hindering speaker operation.
  • Keeping a spare system on the shelf will virtually eliminate system down time concerns.
