Annual inspection of high voltage lines devices


Inspection must to check periodically electric lines devices working:


- Control for distance of detection with adjustment if necessary (adjustment of device sensitivity).

- Usual functions checking 

- Checking of autotest, visuals and audibles alarms, connectic and wiring

- Adjustment software if necessary

- Change of flashlight or buzzer damaged

- Tests-driver training


A report of inspection is write for every high voltage overhead electric lines detector.


Maintenance agreement of devices


Maintenance and control of detectors on your set of vehicles. If there is a breakdown or a malfunction, we ensure the device of detection repair.   

Study according to detectors set.


Electric adjustment of vehicles

Electric equipment for commercial vehicle which need to have a source of energy necessary for instrumentation devices working concerning technical vehicle of measures.


- Study, adjustment for an electric supplying from technical batteries and a converter

- Realization of an electrical panel - protection by circuit breakers

- Electric distribution to workstation - wiring in respect of EMC norms which is applicate to radioelectricals disruptions risks.

Specifics studies: prevention and safety

On specification, JMJ Technologie propose to study possibilities to adapt a device of detection to machines for building site in a safety objective.
