Another Ramp Question

I want to use the semi closed space in parking lot behind my building as a garage. But this place is 87 cm higher from the ground. And i need a ramp.



This ramp should be removable because this place is a parking place and no space for the ramp



So my project was a folding ramp with hinges. But it is not safe to fold 2.5m ramp for one person. So may be anyone have an idea about how it could be simply. (It shouldn't be stolen when not in use also)

Dual Fold Ramp?

Have another hinge in the center...This would make one-person folding easier as well as giving more space for the length of the bike.

You mean like this:




It is possible to do that but a little bit more complicated.
What else can it be as simple as possible?

Try just backing the truck up the the edge with the tail gate down and roll the bike off into the parking space.

Exactly what I meant.

If the dual fold is too complicated; you could always use a sliding ramp. In the US, trucks made for moving furniture use a ramp that slides under the "box" of the truck. The hinge would have a wheel on a pivoting arm that would ride in a "track" on the side of the ramp. When you were done with the ramp, the arm would pivot towards the apartment building and the ramp would slide onto the horizontal surface with the wheels and track. I apologize, but it is difficult to explain.

I didn't understand exactly but i think this mechanism would be nice.
The ramp slides horizantaly as one piece inside of the apartment with a mechanism. Any photographs or details would be great.

I didn't really want to work today anyway

Check out the attached sketch; does that clarify what I mean?

Wooow! That was the detail i was looking for!
Thank you very much.
This is very useful, i can use this.
And very nice sketch. Are you an architect?
(By the way i am an architect)

Mechanical Engineer..but we are all the same

Ok now you need to make use of a garage door opener so you don't have to get off your bike.

I have also attached a pickture of a ramp I use - cost a $100 cdn.

Very nice detail.
Which material do you recommend?
Alu or steel?

Aluminum - much lighter. I also added strips of grip tape to prevent slipping.
