Rotary telescopic boom lift

1 . A rotary telescopic boom lift, comprising at least one vehicle, which can move on the ground and a rotatable assembly comprising at least one telescopic boom adapted to support a work accessory and a cab configured to accommodate an operator;

at least one ladder coupled externally to at least one wall of said vehicle;

at least one handle configured to move between a first configuration for minimum space occupation and a second active configuration, in said first configuration said handle being entirely arranged below a rotation area of said assembly, in said second active configuration at least one portion of said at least one handle protruding upward beyond the upper profile of said vehicle, being arranged in the rotation area of said assembly at least proximate to said ladder;

and at least one sensor adapted to monitor instant by instant the first configuration and second active configurations assumed by said at least one handle.

2 . The rotary telescopic boom lift according to claim 1 , further comprising two of said handles which are aligned with opposite sides of said ladder in said second configuration.

3 . The rotary telescopic boom lift according to claim 1 , further comprising at least one locking element, which is arranged to interfere with a free movement of a respective one of said handles and is configured to be deactivated, at least temporarily, for clearance to transition between said configurations.

4 . The rotary telescopic boom lift according to claim 1 , wherein at least one handle is of the telescopic type and is coupled slidingly to said ladder.

5 . The rotary telescopic boom lift according to claim 4 , wherein said handle is accommodated slidingly within a stringer of said ladder.

6 . The rotary telescopic boom lift according to claim 3 , wherein said at least one locking element comprises a knob which is arranged along one side of said ladder and is arranged to interfere with the sliding of said handle.

7 . The rotary telescopic boom lift according to claim 3 , wherein said at least one handle is coupled rotatably to said ladder, in said second configuration said handle being aligned with a first side of said ladder, in said first configuration said handle being rotated by 90 degrees about one end of said ladder, with respect to said second configuration, and being directed toward a second side of said ladder.

8 . The rotary telescopic boom lift according to claim 3 , wherein said locking element comprises a stop member arranged at an end of said ladder.

9 . A rotary telescopic boom lift comprising at least one vehicle which can move on the ground and a rotatable assembly comprising at least one telescopic boom adapted to support a work accessory and a cab configured to accommodate an operator;

at least one ladder coupled externally to at least one wall of said vehicle;

at least one handle configured to move between a first configuration for minimum space occupation and a second active configuration, in said first configuration said handle being entirely arranged below a rotation area of said assembly, in said second active configuration at least one portion of said at least one handle protruding upward beyond the upper profile of said vehicle being arranged in the rotation area of said assembly at least proximate to said ladder; at least one sensor adapted to monitor instant by instant the first configuration and second active configuration assumed by said at least one handle, said at least one sensor being associated with a control and management unit, and instructions for the at least temporary inhibition of the rotation of said assembly when said respective handle is arranged in said second configuration.
