Abstract
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 the retracted and extended positions is also provided, as is a mechanical arrangement for pivoting the mast between generally horizontal and vertical positions. The mechanical arrangement includes a drive mechanism operable independently from the pneumatic control system which is capable of securely maintaining the mast at any desired angle between the horizontal and vertical positions. The mast includes an AC powered light source mounted at the upper end of the mast. The improvement of the mast comprising the inclusion of a converter for converting DC power to AC power so that the light source has the capability to run on the same DC power source as the pneumatic control system and the arrangement for pivoting the mast.
