One man Rigging. By Kevin Pickering.

The base unit has the car scissor jack welded to it. I welded a spigot
to the top of the jack, this slots in the cradle unit close to the angle adjuster. The large
wheels take most of the load. The arms with the small wheels keep the dolly upright, the wheels
being just clear of the ground if the dolly is held vertical. |

The wing cradle is made of square tube, plywood and a carpet cover. I've had to glue a rubber
sheet to the center of the carpet to stop the wing sliding along when trying to move the wing/dolly
combination. What you can't see properly, in this photo, is the device that holds the wing in place.
Once the wing is pulled out of the trailer and placed in the dolly, the device is loosened, slid
down over the wing and tightened. |

This is a close up of the angle adjuster. This is used to line up the fwd and aft wing bearings with
the A/F pins.
This image shows the base unit and cradle assembled. The jack raises or lowers the wing to align
wing/fuselage and spar/opposite wing bearings after the first wing has been inserted and trestled.

In e-mail people saying it's hard to see how I could get the 107kg wing onto the dolly.
I don't know how your trailer is configured but in my LAK trailer the wing root end is supported
in a wheeled dolly, on rails, at the far end. The wing is then supported on the side of the trailer
in the middle and at the tip. So, basically, this is how I rig - fuselage out, dolly alongside fuse'
just aft of wing area. Now this is the heaviest part - lift wing tip up and away from support.
Pull wing out of trailer until airbrakes almost level with dolly, rest wing on dolly. Move down
wing and slide the retainer (attached to cradle) over wing and lock. Move back to tip and pull wing
out of trailer until root dolly is on trailer door. Push down on wing tip to "seesaw" the root
dolly off of the door and onto the ground. |

Pull wing out, along the side of the fuselage until the spar aligns with the fus' cut outs. Apply
upward pressure on tip (which puts positive pressure on root dolly, to hold it in place) and walk
the tip round (in an arc) until the wing is 90deg to fuse. Casually walk (trying to look cool)
down to the root (the wing is balanced in the wing dolly), remove the root dolly from the spar,
rotate the wing and maneuver the wing into the fuselage and engage the bearings. |
