If you built something like that, that did not need to go 'ground to
loading ramp' like that can, I think you could build something more
robust and with better weight capacity.
I wonder if there's an air resevoir somewhere in there to provide some
suspension in addition to the 'leg flex' suspension?
If you didn't need to go to dock height, you could omit the front
lifting mechanism as well.

The concept is fine, the execution of this one is terrible. Others have
mentioned the mechanical disadvantage on the cylinder, my first issue
was the long spider legs for the axle mounts. Think bending and twist on
the mount arms.
A well executed trailer that could go from essentially ground level to
dock height with an 18" deck height for transport would really be handy
for anyone who has do deal with truck freight shipments. Ramps have
their place but a 3000# crate is a bear to deal with on a ramp. And
pallet jacks and ramps do NOT mix.

Good idea. Poor execution.
Needs a way to lock the wheels to the frame that does not rely on the
long moment arm acting on the lift shafts.
Maybe a shock absorbing system, betwen the lock point and the ground, too.
I susppect any damage done was due to overloading or overloading and
rough terrain both. Maybe a rated load and really rough ... Maybe.

Only thing I'd do different is mount the pivots forward. I'd want a
trailing arm suspension, not leading arm so if a wheel jams etc the
trailer does not attempt to "launch" the load.
