Patent attributes
An apparatus for assembling a positive seal coupling and a pipe, including a frame, a stationary block assembly attached to the frame and having coupling gripping doors, and a traveling block assembly slidably attached to the frame and having pipe gripping doors. Two hydraulic ram cylinders are attached to the frame that have ram cylinder rods attached to the traveling block assembly so that the hydraulic ram cylinders can move the traveling block assembly toward the stationary block assembly. The coupling gripping doors are axially aligned with the pipe gripping doors so that when the hydraulic ram cylinders move the traveling block assembly toward the stationary block assembly, a pipe held by the pipe gripping doors is inserted into a coupling held by the coupling gripping doors.
