Boom

Boom Formed by three segments: one is fixed, two are hydraulically extensible by means of a hydraulic double-action and return cylinder.

The system allows to extend the boom in a synchronous way.

Boom lifting operations are managed by a double-action cylinder which allows a -5° to 70° swing angle.
