ABSTRACT:
A pipeline assembling apparatus used in assembling together large diameter PVC pipes into a pipeline includes a gripper assembly having an upright member for placement adjacent a side of an end of a second pipe to be inserted into an adjacent end of a first pipe and a pair of upper and lower horizontal members extending in cantilevered fashion outwardly from the upright member and generally parallel to one another for placement respectively above and below the end of the second pipe, an actuator assembly spaced from the gripper assembly and having a lower yoke of an inverted U-shape formed by a top horizontal member and a pair of vertical side members for placement over the end of the first pipe and a handle fixedly attached to the top horizontal member of the lower yoke, and a link member extending between and pivotally connected at one end to the upper horizontal member of the gripper assembly and at an opposite end to the handle of the actuator assembly such that by manually pulling on an upper extension of the handle in a direction away from the second pipe the end of the second pipe is gripped between the upper and lower horizontal members of the gripper assembly and the second pipe is pulled with the gripper assembly toward and guidably inserted into the adjacent stationary end of the first pipe.
