TRAILER DOOR RAMP LIFT ASSIST DEVICE

机译:拖车门坡举辅助装置

摘要

A trailer door that opens by hinging downward to double as a ramp for loading/unloading cargo and an improved assistive means by which such doors are opened and closed is provided. An assembly comprising a ramp pull point that is set apart from the plane of the ramp/door, and/or is moved outward from its edge, changes the physics of the tension required for the assistive lift force for any given ramp/door which in turn allows the spring or cabling counter-weight mechanism to be deployed substantially removing it from blocking the sides of the ramp/door.
