Abstract:
1. An apparatus for supporting a substantially cylindrical pipe, said apparatus comprising: a structural frame including a support arm assembly; said support arm assembly including first and second support arms, said first support arm pivotally mounted to said frame and thereby defining a first pivot axis, said second support arm pivotally mounted to said frame and thereby defining a second pivot axis, said first and second support arm each including an engagement feature and wherein each support arm supports the pipe at a separate point; and wherein said first and second pivot axes are not coaxial; a camming assembly including at least one camming member, said at least one camming member engaged with each of said engagement features of said first and second support arms wherein movement of said camming assembly simultaneously repositions said engagement features of said first and second support arms and thereby repositions said first and second support arms; a pipe clamping member moveably mounted on said frame independent of said support arm assembly; and wherein adjustment of said camming assembly defines a plurality of positions of said first and second support arms, said plurality of positions corresponding to a plurality of different pipe diameters wherein a plurality of pipes having different diameters are supportingly engageable between said support arm assembly and said pipe clamping member.
