Abstract
A pneumatically telescoping mast adapted for mounting an electrical fixture is disclosed. The telescoping mast includes a pneumatic control system to extend the mast from a retracted position to an extended position. The mast is made up of adjacent telescopic sections, each section slidable relative to an adjacent section, each section slidable between the retracted position and the extended position. Mechanical arrangements are disclosed for pivoting the mast between a generally horizontal and a generally vertical position, including drive mechanisms operable independently of the pneumatic control system and adapted to securely maintain the mast at any desired angle between the horizontal and vertical positions.
