Hydraulic scissor lift. Made up of 5 objects: Basement, Jacks, Pillars and Platform
This model is already animated.
To animate the dynamics of this vehicle I used a very few tools, which makes it easier for your to handle the model, and add it to scenes, or newer animations.
Basement has motor and tubes. Hydraulic jacks do the right decompression movement. Pillars act just as they do in real life (welding seams can be visible on them within closeup). Platform has corrugated surface bumped in proper way.
