Rotary telescopic boom lift

A rotary telescopic boom lift, comprising at least one self-propelled machine, which can move over ground and supports in an upper region a rotating assembly, associated with said machine by way of a rotary coupling element, said assembly comprising at least one turret and an operating boom, which is articulated to said turret with a first end thereof, and further comprising means for supplying electrical power, at least for a movement of said machine, a rotation of said assembly and an actuation of said boom, said means comprising:

• at least one first battery of high-energy storage units, such as drive batteries, which is integrally supported by said machine and is arranged substantially below said rotary coupling element,
• at least one second battery of high-energy storage units, such as drive batteries, which is supported by said assembly and is configured to rotate with respect to said machine integrally with said assembly, said at least one second battery being arranged substantially above said rotary coupling element, said at least one first battery and said at least one second battery being electrically connected, for a mutual flow of electrical power.
