The invention relates to a self-balance platform for woodland machinery, belongs to the field of forestry machinery, and provides needed connection for a forest tree parameter collector. The platformis composed of a movement upper platform 1, a pedestal 2, an electric cylinder 3, a servo motor 4, a servo driver 5, a gyroscope, a control system and a control panel 6. An electric driving leveling platform has advantages including high leveling precision, short leveling time, safe and reliable performance and convenient maintenance, has high environment capability and self-locking capability, can cope with complex forest work environment effectively, provides a horizontal work surface for the data collector, satisfies the lifting requirement, and reduces vibration of the data collector due to outside factors. The closed-loop design of the leveling device enables high working stability and flexible instantaneity of equipment, real-time leveling and fixed-point leveling can be realized, operation is simple and convenient, and a lot of forest tree parameters can be obtained rapidly.
