ABSTRACT:
A bolt (54) is inserted threaded end (60) first through a first opening (50) within an arm portion (14) of a C-shaped saddle (12) then through a larger opening (52) in the second arm portion (16) of the saddle (12). The opening (52) is hexagonal in shape. A nut (62) is then installed on the bolt (54). The nut (62) has a small end portion (64) which is hexagonal in shape. The nut (62) is hand tightened and then is aligned with the opening (52) so that the small end portion (64) will be aligned with the opening (52). A wrench is then used on the head (58) of the bolt (54) for rotating the bolt (54) for the purpose of drawing the nut (62) and bolt (54) together and applying a clamping force on a pipe (22) which is in the saddle (12). The saddle (12) is connected to a support leg (24) constructed from two bars (26, 28) which are welded together and to the saddle (12) at their outer ends. The bars (26, 28) are spread apart and at there inner ends (38, 40) are welded to a support structure (42). Thus forms a triangular truss (48) which is rigid. The welded together outer end portions of the bars (26, 28) form a beam section (34) which is in effect a cantilever beam secured at its inner end to the truss (48). This beam section (34) bends in response to shock loads applied on the pipe hanger.
