Section 1 Introduction Review this manual in its entirety. Contact the Will-Burt Company with any questions before performing any procedure outlined in this manual.

The Snap Dragon™ MKI-M1 scissor lift is a fast, robust, low-profile elevation solution for cameras and other sensors.

Compact design gives the scissor lift nearly a five-to-one deploy-to-stow ratio which allows payloads to be hidden when not in use.

Durable design allows the scissor lift to perform in harsh environments where dirt and dust will not affect the performance of moving parts.

Flexible design enables the system to be installed and operated at various angles expanding the potential uses for the scissor lift. Horizontal mounting would allow the undersides of bridges or large vehicles to be inspected. Inverted mounting would allow payloads to be lowered into containers and caverns.
