36 a pivotally attached to a trough lift bearing 22 a located below the trough 22 at a point on its longitudinal centerline axis trough hinge assemblies 38 further secure the trough 22 to the stabilizer frame 30 these trough hinge assemblies 38 are comprised of saddle links 38 a mounted at the semicircular ends of each of the trough saddles 34 trough links 38 b mounted on the perimeter of the trough 22 and removable trough hinge pins 38 c selective removal and or placement of the hinge pins 38 c will allow the pipe support trough 22 to be tilted on the trough bearing assemblies as it pivots on trough lift bearing 22 a to either side of the pipe lifting structure 20 as may be desired by the extension of the ram 36 a of the trough lift 36 in this manner pipe lifted in the trough 22 can be rolled from the trough 22 to either side of the lifting assembly 20 as may be required by a user as shown in the figures lifting arm lift assemblies 40 having an extendable and retractable rams 40 a are pivotally mounted to the carriage 16 positioned between the first 24 and second 26 lifting arm assemblies the rams 40 a of each ram assembly are pivotally mounted to a bearing 42 on the first lifting arm assembly 24 in a manner such that.
