Abstract
PCT No. PCT/US79/00501 SEC. 371 Date July 16, 1979 SEC. 102(e) Date July 16, 1979 PCT Filed July 16, 1979 A mobile apparatus (20) has a hydraulically operated pivoted boom (22) and a hydraulically operated pivoted arm (24) and on the free end of the arm is a hydraulically operated mechanism (26) for handling heavy loads in ways that cause torsional and bending distortion of the boom (22) and the arm (24). Coplanar steel hydraulic conduits (42a and 42b, and 45a and b to 50a and b) are slidably carried in conduit support blocks (57); and those blocks in turn are mounted on brackets (53) fixed to the arm (24) or brackets (69) fixed to the boom (22) by carrying means (56 or 72) which allows directionally unrestricted limited movement of the blocks (57) in a plane parallel to that of the conduit centers, and which also allows axial movement along lines perpendicular to that plane. The guard structure (100 or 101) of the present invention is similarly mounted for limited movement and includes readily removable conduit coupling guard members (104, 107, 108 and 109) to facilitate tightening conduit couplings (43a and b and 50d and e).
