Vertical Positioner
The vertical positioner consists of two components each of which contains an acme
screw and the associated nuts, bearings, and power transmission hardware to
securely lift and position either the pipe cut-off clamshell or the end preparation tool.
A series of holes allow adjustment in attaching the slings to the pipe cut-off
clamshell. Spring-centering pillow blocks provide a compliant attachment of the end
preparation tool to the vertical positioner, allowing the tool to be easily aligned with
the axis of the pipe. A worm gear driven mechanism is used to provide control of the
orientation of the end preparation tool for use on pipes coming through either the
ceiling or the floor.
