A scissor lift device is provided having twin vertical screws that act to raise or lower a substantially horizontal and flat platform using a pair of scissor jacks . A single DC motor can be provided within the scissor lift device housing, and is operatively connected to one vertical screw. The other vertical screw is connected to the first by a locked linkage that passes from one screw to the other in the base of the scissor lift device. As such, rotation of the motor results in an equal movement in both vertical screws, and thus equal movement of both scissor jacks. The configuration is easily serviced and installed, and is adapted to have the stationary and moveable components each covered by a protective shells. Additionally, the platform of the device can be easily leveled using a locking pin to lock the platform in a level position once the base of the device has been installed.
