PME700 maximises safety and the operational value of your demolition fleet.

Demolition is a dangerous business. Pulling down a building demands skill, control and planning. James Fisher Prolec’s working range indicator enables operators to increase functionality without compromising safety, allowing smaller machines to be used and therefore reducing operating and transportation costs. 

James Fisher Prolec’s solution for the high-reach demolition market, PME700 is ideal for superior demolition safety and constantly monitors the machine across all planes providing real-time indication of the precise position of the demolition tool. 

In recent years the size and reach capabilities of high and ultra-high reach demolition machines, along with their deployment has increased dramatically. As a result, demolition stability monitors (DSMs) or working range indicators (WRI) are become increasingly used in today’s highly professional demolition market. PME700 will indicate the safe zones of the machine ensuring operators can fully utilise the machine’s capacity.

The system also continually calculates the distance between the demolition tool and the cab to ensure that falling debris doesn’t strike the cab. PME700 can also be tailored to include overload, tool weight, drop zone protection and slew dependent working ranges, for non-standard long-reach demolition equipment. 

For more information, please read the PME700 user manual.
