Abstract: A crane is operable in either a regular mode or a heavy duty mode. In the regular mode, an upper works is rotatble, through a turntable bearing, on a lower works. A boom is pivotally connected to one end of the upper works and a counterweight is connected to the opposite end thereof. In the heavy duty mode, a support ring surrounds the lower works and is connected thereto. An auxiliary frame is mounted on the support ring, surrounding the upper works, for rotation on the ring in unison with rotation of the upper works. The boom used in the regular mode is pivotally connected to the auxiliary frame for use as a gantry, and a heavier boom is pivotally connected to the auxiliary frame adjacent the gantry. The counterweight of the machine in the regular mode is shifted to the auxiliary frame opposite the boom and gantry, and an auxiliary counterweight is added to the auxiliary frame.

Abstract: The turn tilt table is preferably mounted on a self propelled mobile vehicle for carrying a test article such as a military vehicle weighing up to 70 tons. The mobile vehicle is driven to a plurality of test sites at which radar beams or the like are directed against the test article for determining vehicle radar signatures or the like. During testing, the turn tilt table may be tilted anywhere between a horizontal position and 45.degree. from the horizontal; and may be pivoted 360.degree. about an axis normal to the plane of the turn tilt table to any of a plurality of positions within 360.degree.. If vehicles are being tested, a ramp is connectable to the table to allow the vehicle to be driven onto or off the table.
