We use a similar trolley at Locksley for our Falke SF25C. The gap in the
track is about 150mm from memory, and the trolley has four sets of
wheels spaced at about 150 mm so it can straddle the gap.
We use a very simple design, with ball bearings mounted on the outer
face of a piece of angle iron, projecting through slots in the webs of
the angle to run on the angle iron track. This gives a very small height
of the cradle, and allows the aircraft to be pushed onto the cradle by
one person.
I am not describing this well. If anyone wants more info, I could take
some photos, and get the OK from the designer/builder of the cradle to
make it all public.
Our track has two parallel rails of angle, so that the cradle has a firm
surface to run on when it tilts into the loaded position.

Dear Anthony
Thanks for the advice. We may well make a removable bridging piece if we
have any trouble with our multiwheel trolley in reliably spanning the 330 mm
gap (3 door tracks sadly, not two and thus narrower).
If the basic design will work 99% of the time and a bridging piece is used
99% of the time then the reliability of crossing the gap will be acceptable
given that the scheme has to work with all manner of club members.
Cheers

The AUGC approach for the hangar door rail problem was to have the track for
the glider a little above the track for the door. The glider track had a
gap at the door track. We had a little removable bridge to cross the gap
over the door track. You just had to make sure the bridge was there when you
wheeled the aircraft out.
I don't recall any aircraft becoming de-railed because someone had forgotten
the bridge...

Dear Ron
A variant on the side ways loading hangar, such as one finds at Benalla &
Beaufort GC at Bacchus Marsh, is detailed in Sailplane & Gliding April-May
2005 at page 45.
The Benalla/Beaufort approach works with relatively simple trolly designs to
carry the glider main wheel and assumes that the hangar sliding doors at the
bottom are not guided by continuous guides rather by intermittent guides so
that the angle iron track for the glider main wheel can be continuous,
running slightly underneath the bottom of the doors. If you concrete
continuous door tracks into the ground to fully guide the hangar door bottom
egdes and have a concrete hangar floor, such as we have at VMFG with a
sideways loading hangar we are finishing off, then you need a more
sophisticated trolley because the angle iron carrying the glider mainwheel
is forced to be discontinuous at the door tracks. So we have 4 Vee groved
wheels well spaced out over more than a metre running on the angle iron.
Trolley to be tested soon - Should work well but yet to be 100% proven in
the real world.
The tail end of the glider simply runs in on the tail dolly, no additional
track necessary.
The hangar width only needs to be fuselage length plus tail and nose
clearances.

I am looking for information on the "sideways hangars" set up at Benalla if
some one who has their glider so accommodated therein esp if an open class
glider, would be kind enough to write to [EMAIL PROTECTED]
