Tower (construction) Cranes, Current collector (sliders)

These types of sliders are characterized by the following operational characteristics:
a) low speed (up to 10 km / h)
b) high values ​​of current (up to 1000 A), with frequent interruptions in operation and high mechanical load on the shock.
Material slider:
– Hard coal for electricity up to 300 A,
– Hard coal impregnIiran paraffin oil for current up to 300 A,
– Metalografit for currents up to 1000 A.
