Trike trolley

 

This is a building instruction for a trike trolley. I got the basic design from Larry Wallace, Tuscaloosa, Alabama : http://www.social.trikepilot.com/profile/Larryboy

This instruction is only meant to be an overview. If you need more details please send me a mail: kullabacken[at]horby.nu
 

The original trike trolley from Larry Wallace

Use 40x40 square pipes

Use flat steel 40x8

The plates must be rocking for easy roll on/off

The size of the plate is dependant on the size of your rear wheels

You need to reinforce the square pipies in the rear, due to the weight of the trike

A simple 10 mm bolt is sufficient to retain the front wheel

Make sure you have the right angle. The trolley should have a clearance of about 30 mm

Make sure the angle is correct and then weld

When you are done, this is how it should look

When the right angle is determined, cut off some material to make the joint a better fit.

Put everything together

Weld a border for the rear wheels (optional)

For easy dragging you need to weld on a latch, and make a corresponing dragging rod with a hook.

Start spraying the primer

And then a nice coat of Ferrari red

The retaining bolt for the front wheel might have to be bigger depending on your front wheel

Ready !

Note the rod with the hook for pulling or pushing

Steel bar 16 mm.

If you make a tight lateral fit, the wheel will stay in a straight ahead position all the time.

Note that when the trike is dragged onto the trolley, the wheel plates are tilted automatically enabling easier loading.

When the wheel goes backwards, the plate tilts accordingly.

This trolley is designed to be dragged in and out of an hangar in a straight forward direction.

UPDATED VERSION

Having had problems maintaining a straight line with the fixed wheels the trolley was rebuilt.

With this modification it is now very simple to steer the trolley and the construction is still easy to build

The modification does add height, but it is not a problem having the tiltable accessing ramps made long enough

This is what it looks like today.

It turned out nicely concidering the very easy one man handling

If you have a more rugged surface you might want to use the rod with the hook, to allow a helper to drag or push via the double sided latch.
