A fully electric lift device includes a base assembly, a lift assembly, a platform assembly, tractive elements, an energy storage device, and a control system. The lift assembly is coupled with the base assembly and is driven by an electric linear actuator for a lifting function. The platform assembly is positioned at a top of the lift assembly and can be raised or lowered as the lift assembly performs the lifting function. The tractive elements are rotatably coupled with the base assembly and can be driven by an electric wheel motor to perform a driving function. The control system includes a controller that operates the electric wheel motor and the electric linear actuator to perform the driving function and the lifting function using power drawn from the energy storage device. The lift assembly and the tractive elements use only electrical energy to perform the lifting and driving functions.

A scissors-type jack includes a jack body, a gear box, a motor and a battery pack. Upper ends of lower supporting arms of the jack body are respectively hinged to lower ends of upper supporting arms of the jack body through hinge shafts. The gear box includes a base, a housing, and first and second gears. The base is fixedly mounted with one hinge shaft. A gear transmission shaft of the first gear is rotatably arranged on the base and meshed with the second gear. The second gear is connected to a screw rod of the jack body. The motor is mounted on a side of the base, and a motor gear shaft penetrates through the base and is meshed with the first gear. The control board is disposed on an outer side of the battery pack and electrically connected to the battery pack and the motor.

A lifting column includes at least five column elements which are at least partly nested, and a first and a second drive arrangement. The first drive arrangement is configured to move the three innermost column elements relative to one another. The second drive arrangement is configured to move the three outermost column elements relative to one another.
