Reduce Diagnostic Risks with Heavy Machinery

Reducing Diagnostic Risks with Heavy Machinery - Front end loader in open mine - Parker Hannigin When your job requires you to run diagnostics on a bulldozer that’s moving along a railroad track, safety is a chief concern. However, when you’re using wired monitoring devices, trying to do the job safely can be difficult.

That was the issue facing a customer that retrofits these mobile, heavy-duty assets to perform tasks along rail lines. The bulldozers are outfitted with special wheels to move along the track, and attachments to perform specific maintenance, like cutting grass. Their clients were having problems safely performing diagnostics of the equipment’s hydraulics lines, primarily because:

  • Manual monitoring devices connect to sensors with cords, which can get wrapped and snagged by moving parts
  • Conventional diagnostic technology requires the technician to be close to the asset while it’s in motion, putting workers in potentially dangerous situations

Additionally, the large size of the manual sensors (about six inches in length) also made it difficult for technicians to properly attach them to pressure lines, forcing them to actually duct tape the sensors as close as possible.

The solution

The customer needed a solution that allowed maintenance technicians to perform accurate pressure diagnostics from a safe distance while the machine was in service. Rather than rely on the bulky manual sensors, the customer installed two wireless SensoNODE™ Blue pressure sensors at critical points on the machine.

The sensors offer multiple benefits, including:

  • The small size of the sensors allows workers to install the sensors properly while still in the shop, saving time in the field
  • Sensors are installed closer to points of interest, improving accuracy
  • When used in tandem with SCOUT™ Mobile software installed on their mobile devices, technicians can track data from both sensors simultaneously
  • The wireless design allows technicians to perform diagnostics far enough away to help keep workers out of potentially dangerous situations
  • User-defined alerts warn of dramatic pressure drops/spikes, with notifications sent to each technician’s mobile device


Customer value

SensoNODE Blue sensors and SCOUT Mobile software make the diagnostic process more efficient. With multiple people using SCOUT Mobile on their devices, they can run diagnostics in the shop to identify and correct any issues even before the equipment is taken out to the field. This helps reduce the time for in-service diagnostics, as well as returning the equipment to the shop for any subsequent repairs.
