Scissor Platform
A scissor platform (AKA scissor lift) is a work platform which can be moved into place, then raised and lowered to various heights.
The scissor lift is perfect for elevating a camera position when space is limited. The camera operator drives the lift up and down with simple controls.
The scissor lift is similar in function to the cherry picker which is also used in film and television work.
Other types of platform elevator include screw lifts, rack and pinion lifts, telescoping lifts and articulated lifts.
