 Electrification and outfitting

Conduct power supply ,

Phase control guard opens the main contactor in case of phase failure

The flate cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists.

clean and smooth flat cable power supply system                               

Cables are coded either with numbers, colours or tags for easy identification.

All hoist and crane movements are independent and can be run simultaneously.

The control panels are finished to withstand corrosion, IP54  

The components are positioned in a maintenance friendly way, and the whole layout provides good protection against accidental contact.

The multi-wire type fixed cables with plastic insulation are intended for crane usage.
