FUNCTIONING

AND SAFETY DEVICES OF THE MACHINE

The Gold Lift 1470 aerial platform is divided into two main parts:
1.

Undercarriage part

2.

Aerial part

If you use the machine during the translation or while it is stabilized, you operate the undercarriage
part; if you are working

in altitude (height)

, then you operate the aerial part.

The operation of the two parts and their functioning is controlled by an electric panel consisting of
the assembly PLC + relay control; the relays are inside the electric components housing, on the left
side of the machine.
