  • $\begingroup$ Is this based on a real scissors lift? Do you have an accurate blueprint? Can you provide the blend file? In order to animate this properly the dimensions need to work out. You could also think about using empties at your pivot points and parenting the arms to the empties. $\endgroup$

  • $\begingroup$ scribd.com/doc/95476293/… in figure 2 it shows the hydraulic cylinder on the fixed pivot. Yours seems to be on the moving pivot side? $\endgroup$

  • $\begingroup$ i did not use pivot point for the hydraulic cylinders. i youse 1 bone paired to the scissor frame then second bone is paired to the scissor frame bone with free transform enabel and also paired to the cylinder or piston. and the same at opposite side. and then last the bone parent with cylinder and piston is traced to each other by contraint. the track to just cant keep up doing the job aming at the right 3d curser point i put dead center at the hook point on cylinder and piston when is hook on the frame part $\endgroup$

Markom3D has recently done a small YouTube series on modelling and rigging a SciFi landing gear here. He explains how he modelled the pistons at 6 minutes in part 1 and how the model is rigged in the final part called 'How to rig a SciFi landing gear'. Hope that is of some help.
