Zusammenfassung:	An improved pneumatically telescoping mast supported for pivotal movement in opposite directions is provided. The mast includes adjacent telescoping sections slidable relative to one another between retracted and extended positions. A pneumatic control system for displacing the mast sections between retracted and extended positions is also provided as is a system for pivoting the mast in opposite directions about the pivot axis between the horizontal and vertical positions. The mast includes a light source mounted at the other upper end of the mast which is capable of running on the same DC power source as the pneumatic control system and the mast pivoting system.
