Prolec PME 500 – RCI, Height and Slew Limiter

Height, Slew Limiter, and RCI with automatic machine stop.


Prolec PME 500 Height, Slew Limiter, and RCI System. This system is more than just a solution; it’s your gateway to the best contracts, setting unprecedented standards for safety, precision, and operational excellence.


Introducing the Prolec PME 500 Height, Slew Limiter, and RCI System:


The PME500 range combines Prolec’s market leading RCI, height, and slew technologies into one intuitive system by delivering asset and operator protection against hazards above and beside the machine, while also protecting against over-loading and tipping.

The Rated Capacity Indicator included in the PME500 range physically restricts the movement of the machine should it approach the machine’s safe working load (SWL).

Hydraulic motion cuts are standard on all PME500 systems to automatically stop the machine when movement and capacity limits are reached.


Key Features of the Prolec PME 500 System:


Advanced Height, Slew, and Load Monitoring: Real-time height, slew, and load monitoring offer unmatched accuracy, ensuring machinery operations stay within safe limits.

Intuitive Interface: The user-friendly interface provides operators with real-time measurements, visual cues, and customisable alerts. It simplifies complex data, allowing operators to focus while staying informed.

Data Logging as Standard: The system captures detailed operational data, for audit purposes.

Automatic Machine Stop: This system takes a proactive approach. When limits are reached, it doesn’t just monitor – it stops the machine, minimising accidents and damage.

Seamless Integration: The Prolec PME 500 System effortlessly integrates height, slew, and load monitoring with diverse heavy machinery, ensuring a smooth implementation process.

Access to Best Contracts: With the Prolec PME 500 System, you gain a competitive edge. It’s not just a solution; it’s a ticket to access the best contracts, where safety and precision are paramount.
