A boom system for breaking and/or manoeuvring oversize material, the boom system being adapted to be mounted on or attached to a vehicle, the boom system comprising:
- a base;
- a column protruding upwardly from the base;
- a boom arm moveably connected to the upright column;
- and
- means for moving all or part of the upright column towards and away from the base so that the connection between the boom arm and the upright column is moveable towards and away from the base.
The boom system as claimed in claim 69, wherein the actuator comprises a wedge mounted on a ram, preferably hydraulic in such a way that the wedge is slidable between the outside surface of the external upright column and the actuating member of the locking pin for forcing the locking pin out of the aperture of the internal upright column overcoming the biasing force of the biasing means thereby releasing the upright column from the extended position.
