HORIZONTAL PERSONNEL ■ 119 electrical tractors in operation at CERN in 2016 TRANSPORT 15/09/2020 JM Chevalley, EN-HE-HM, November 2016 7

MAINTENANCE ASPECTS ■ Maintenance-free AC motor ■ Maintenance-free GEL battery ■ Electrical equipment – No hydraulic ■ Battery charger designed to be permanently connected in the tunnel during several months ■ Preventive maintenance : 2 x 1. 5 h per year / per vehicle ■ Corrective maintenance – Only minor problems reported 15/09/2020 JM Chevalley, EN-HE-HM, November 2016 8

SAFETY ASPECTS ■ CE Certification ■ Maximum speed limited (programming console) ■ Dead-man pedal to force the driver to keep both feet inside the vehicle ■ Automatic electrical braking system ■ Automatic parking brake ■ Towing capacity allowed until maximum 1000 kg (small trailer) ■ Driving test to be passed before using a tractor at CERN 15/09/2020 JM Chevalley, EN-HE-HM, November 2016 9

LOGISTIC ASPECTS ■ Storage areas in the tunnel or in surface – Access for the maintenance if in surface – Transport of the vehicles in the tunnel (vertical transport) if in surface ■ Battery charging room and 220 VAC plugs along the tunnel 15/09/2020 JM Chevalley, EN-HE-HM, November 2016 10
