SMELL odors like burning insulation, hot metal, burning rubber, hot oil, or natural gas. FEEL any changes in the way the equipment operates.

  • Page 8: Use Stanchions

    Equipment Safety Use Stanchions Use stanchions while pipe is on racks. Do not stack pipe above stanchion height. Failure to do so may result in serious injury or death. ¡PELIGRO! TX02681-05-30-14 Tipping Hazard Never use pipe racks without drop foot properly in place.

  • Page 9: Cutting Pipe Bands

    NOTICE: Only single stack pipe bundles on the roller side of the PolyHorse. Cut only single stacked bundles from the roller side of the PolyHorse, and only without pipe in the roller. When it is necessary to cut bands from the roller side, cut all the inner banding on the pipe bundle then cut the outer two bands last.

  • Page 10: Overview

    Overview PolyHorse The Polyhorse is a pipe rack system designed to stage multiple sticks of plastic pipe at the proper height for feeding directly into a McElroy fusion machine. By doing this, the time consuming task of pipe loading into the fusion machine is greatly reduced increasing overall productivity.
  • Page 11 Screw Jack Assembly - 1875901 The Screw Jack Assembly is used to support the Truss Assembly. The screw jack also allows the operator to level the PolyHorse on uneven terrain and control the roll of the pipe. Pivot Roller Support Assembly - 1876301 The Pivot Roller Support Assembly is positioned on the truss that is closest to the fusion machine.
  • Page 12 Stanchion - 1877101 The Stanchion is an upright that is used on the rear portion of the PolyHorse to prevent pipe from rolling off the rear. There is one Stanchion used for each Truss Assembly. The Stanchion should always be in place when pipe is on the PolyHorse.

  • Page 13: Polyhorse Power Assist (Optional)

    The optional PolyHorse Power Assist can be connected to the fusion machine's hydraulic system to power the front pipe roller on the PolyHorse. The Power Assist is used to aid in feeding pipe into the fusion machine by powering the front pipe roller and has controls to raise and lower the pipe.

    Initial Setup Truss Assembly Insert bottom truss assembly shaft into the j-hook on screw jack assembly. Align the upper holes and insert the detent pin. TX02685-12-6-06 Roller Assembly Insert bottom roller assembly shaft into the j-hook on screw jack assembly. Align the upper holes and insert the detent pin.

  • Page 15: Truss Assembly Positioning

    Set up on solid ground if possible. In soft ground conditions it may be necessary to place screw jack assemblies on a large base to spread out the load and help prevent Polyhorse from sinking into the ground when loaded with pipe. TX02687-12-6-06...

  • Page 16: Adjusting Front Height

    Initial Setup Adjusting the Front Height Before loading any pipe, adjust the height of each front screw jack using speed wrench. The height of the pipe rollers should allow the pipe to be inline with the fusion machine jaws. IMPORTANT: A string or a low cost laser level can be used to check the height of each roller to the height of the fusion machine jaws.

  • Page 17: Stanchions

    Initial Setup Stanchions Insert stanchions in the rear stanchion sockets on each of the truss assemblies. Use stanchions while pipe is on racks. Do not stack pipe above stanchion height. Failure to do so may result in serious injury or death. ¡PELIGRO! TX02691-05-30-14 Additional Truss Assemblies...

  • Page 18: Additional Roller Assemblies

    Initial Setup Additional Roller Assemblies "Piggy-back" additional pipe roller assemblies to the rear for dual fusion machine operation (See Section - Additional Pipe Staging Options). Insert bottom roller assembly shaft into the j-hook on screw jack assembly. Align the upper holes and insert the detent pin. Adjust the height of the roller assembly drop foot.

  • Page 19: Fusion Machine Setup

    Fusion Machine Setup Position Fusion Machine Position fusion machine to the left of the PolyHorse so the movable jaws are facing toward the pivot roller of the PolyHorse. Fusion machine should be in line with the PolyHorse pipe rollers. NOTICE: Pipe should be positioned as shown, being careful not to hit the fusion machine...

  • Page 20: Power Assist Setup

    The optional PolyHorse Powered Assist can be connected to the fusion machine's hydraulic system to power the pipe roller on the PolyHorse. The Powered Assist is used to aid in moving pipe in and out of the fusion machine by powering the front pipe roller and has controls to raise and lower the pipe.

  • Page 21: Pipe Handling

    Pipe Handling Loading Pipe onto the PolyHorse NOTICE: Pipe should be positioned as shown, being careful not to come in contact with the fusion machine. Pipe should be loaded to allow a minimum of 6 ft. of pipe at the end of the rack to extend past the last truss, so that when pipe is fed into the machine, the pipe is still supported by the last roller.

  • Page 22: Cutting Pipe Bands

    NOTICE: Only single stack pipe bundles on the roller side of the PolyHorse. Cut only single stacked bundles from the roller side of the PolyHorse, and only without pipe in the roller. When it is necessary to cut bands from the roller side, cut all the inner banding on the pipe bundle then cut the outer two bands last.
