With Sentinel Cloud, you can monitor your fleet and gain a range of insights.

Managing heavy machinery around overhead powerlines, bridges, tunnels and other height-restricted environments just got smarter.

PRM Engineering’s Sentinel Cloud Height Limiter Data Logging (HLDL) provides worksite managers with continuous operational data and powerful analytics from Sentinel Safety Height & Slew Limiters.

Know what your machines are doing — wherever they are.

With Sentinel Cloud, you can monitor your fleet and gain valuable insight into:

  • Height and slew activity – see when machines are approaching, reaching or exceeding configured limits.
  • Boom height monitoring – review boom height over time.
  • Slew monitoring – track machine swing angle where slew limiting is fitted.
  • Machine pitch and roll – monitor machine level to support safe operation on slopes.
  • Fleet GPS tracking – view the last known location of each connected machine with timestamp.
  • Fault monitoring – identify sensor, output and other system faults.
  • Configuration changes – track calibration and system configuration changes.
  • Maintenance notifications – stay informed when servicing is due.
  • Attachment settings – keep track of changes to excavator or loader attachments.
  • Raw data access – interrogate or export logged data to Excel for further analysis.

One dashboard – your entire fleet

The Sentinel Cloud dashboard brings your machine safety information together in one place, including:

  • Machine status
  • Height and slew data
  • GPS
  • Fault history
  • Maintenance
  • Operational timelines

The result is greater visibility across your fleet and the information you need to identify trends, investigate events and make more informed safety decisions.

Built for Australian conditions

Sentinel Height & Slew Limiters are designed and manufactured in Australia by PRM Engineering, with systems available for excavators, loaders, skid steers and backhoes.
