Electrification and outfitting
slide wire or C shape slide line conductor power supply.
all hoist and crane movements are independent and an be run at same time.
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.
Cables are coded either with numbers, colours or tags for easy identification
The flate cables used for festoons are PVC insulated flexible flat cables rated for 450/750V, specially designed for cranes, hoists.
Festoon cables are suspended on cable saddles, fixed to cable trolleys, running in a galvanised C-track, which is connected to the main girder with bolted or welded support brackets.
Separate trolley structure
