| Measures to prevent unauthorised use |
Tarmac Northern has introduced a series of new working
practices to prevent both the unauthorised use of mobile
plant and to limit idle time.
To prevent unauthorised start up of mobile plant,
keypads have been fitted to the electronic computer
installed in the mobile plant. To start up the mobile plant
at the beginning of the day or after the engine has been
cut out, the ignition key has to be turned and also a
unique PIN code typed into the keypad. If an incorrect PIN
code is entered three times, an audible alarm will sound alerting others to the failed attempts.
To prevent mobile plant being left running whilst unattended, and limit idle time, a movement sensor
within the cab of the mobile plant detects occupancy. If the machine operative leaves the vehicle
unattended for a given time period whilst the engine is running, the sensor will automatically shut down
the engine. Another advantage of this method is the significant cost savings regarding fuel and engine
wear due to idle time on the engine when left running.
A secondary measure to ensure that the vehicle is not left running when unattended is attached to the
handbrake. If the handbrake is applied for a given time period, the same electronic computer this time
linking the sensor on the handbrake with the stop solenoid on the engine will shut down the engine.
