Abstract: A personnel platform assembly and antenna support assembly for wireless communication transmitting and receiving devices such as antennas used in at least cellular telephone networks. The support assembly includes a support frame connectable upon an aerial tower which is adapted for supporting wireless communication transmitting and receiving devices thereupon. A connecting assembly is provided for fixing the support assembly at an above-ground elevation upon the aerial tower and a guide rail is suspended at a distance about the connecting assembly or central column of the tower. The guide rail is adapted for accepting a coupling to the wireless communication transmitting or receiving device and the coupling is continuously positionable along a length of the guide rail for accommodating variable positioning of the wireless communication transmitting or receiving device about the aerial tower.

Abstract: A locking device (1) for use with joints between two telescoping members (28,30) include a bushing (2) with an enlarged head (8) and a neck (6) for inserting into a pair of aligned holes (34) in the telescoping members (28,30). The device is locked by drawing a bolt (16) into the central bore (10) of the bushing (2) by drawing means (20,22,24). The bolt (16) includes a lug (18) for contacting the inner telescoping member (28). Also provided is a channel (14) in the neck (6) which permits the lug (18) to slide within the bushing (2), thus allowing effective engagement of the device (1) for a range of telescoping member wall thicknesses.
