Ya, we have 4 pneumatic cylinders... 2 are the rotary actuators, the other 2 are the small cylinders mounted to the bottom of the frame. The last two were a last minute addition (well actually the whole upper assembly was pretty last minute) but the rotary actuators wouldn't even budge the drawbridge. As far as weight, we are running right around 100 pounds- 98.something last time on the scale- looks like we are going for the steel plate again... lol
