Initial thoughts? I'm not a mechanical engineer but I think you'd be disappointed.
Figure 1. A quick pictorial analysis shows that there is almost no reason for the lift arm to move up.
Also, most of the effort in the linear actuator would be taken up by a force vector from C to A with very little of the effort going into rotation.
Figure 2. An online structural analysis program such as that offered by http://structural-analysis.com may be useful.
This quick little mock-up uses a pin (1) at the left end of your 400 mm lifting arm with 1 kN applied to the arm offset by 100 mm. The rotation is constrained by a roller joint (2). We can see that only 1/3 of the force is going to do any useful work.
You'll have to play around with the scaling on this. It's not optimised for sub-meter parts so you may need to scale up for good visibility.
Figure 3. At the start of the lift the ram is pulling the crank (green) with a starting angle of 45° or so - and the chains aren't even tight yet. This isn't too bad.
Figure 4. The situation appears to be worse when lifting off the truck as the crank (green again) angle is very low. Note, however, that the lift has been flattened against the skip to minimise height and that again the chains are slack. There is no load initially and by the time the chains are taut the crank will be at about 45°.
The skip truck design seems to be well thought out.
