Claim:
A mobile observation tower comprising: a trailer chassis having a forward end and a rearward end configured with a trailer tongue at its forward end to be pulled behind a tow vehicle; and a beam channel disposed on the trailer tongue and centered on the chassis extending rearwardly toward the rearward end of the trailer chassis; and a tower assembly secured to the trailer chassis generally centrally thereon, the tower assembly having pivotally attached thereto and supporting at its upper extent, one side of a generally rectangular observation station, rotatable from a lowered position to an upright position on the tower assembly at its upper extent; and a coupling beam disposed in the beam channel extending generally from the trailer tongue to a position rearwardly of the rearward end of the trailer chassis; and the coupling beam having a fastener disposed on its rearward end for releaseably securing the beam to an immoveable object; and the coupling beam having a pivot latch on its forward end, to which one end of a lifting boom is secured; and a lift link disposed on the side of the observation station generally opposite the side pivotally attached to the tower assembly, and the second end of the lifting boom being pivotally attached to the lift link; whereby when the coupling beam is secured to an immoveable object and the trailer chassis is pulled forward by the tongue, the coupling beam is drawn relatively reawardly in the channel and causes the lifting boom to push on the lift link which rotates the observation station toward the upright position.
