I ahve been asked to make a pair of ramps for a electric disabled scooter thingy so it can be driven into the back of a vehicle. (I assume without the driver sat on it!)

The ramps need to be 7feet long and 6-8inches wide. they need to either hinge in the middle for easy storage in the boot or the need to come apart.

The minimum weight they need to support is 85Kg

I was thinking of some ali treadplate with some right angle extrusion to give it strength. All rivetd together with structural rivets and PU'd see scribble



Description

I value the input of you guys so anyone got any suggestions ? any idea on thickness of material or the best places to get it ? any clever ideas for the hinge/break point ?

cheers

Prolly best if we new the maximum weight!!!
The skid ramps on a brian james transporter are (optional) ally formed (extruded?) so you should in theory be able to make up somthing suitable.
As for the hinged area you can get heavy duty piano hinge but someone cleverer than me would need to work out if the shear strength og the hinge pin was high enough for your application.
Good luck.

As I say - I think the buggy will only be driven up it without the driver sat on it so it just has to hold the buggy weight - which is 85Kg

The driver would add another 22 stone!!! (that would be my dear old dad then....)

Hi Dave

My thoughts are telescopic, something to do with your avatar I suspect.


Fold 4ft long section (local sheet metal shop???) as shown in pic

Fold 4ft long section slightly smaller so that it will slide inside the first one.

Job done


For.

Slide together for storage, extend to 7ft to use, i.e. 1ft overlap.

Use with folds facing upwards to stop wheels coming off the sides.


Against.

Far too low-tech with no *Bling* factor.

All the best mate.

nice idea - but would need 3 sections because the overall stored length should be 3.5 feet to fit in the boot...

Could they not be stashed underneath the vehicle somewhere, they they won't have to be lifted in and out of the boot and the lengthhingeing might not be so critical.

love that logic
