The present invention relates to an electric lift column which is provided to adjust the height of a mechanical device, and more specifically, to an electric lift column which enables a safer and smoother operation by providing psychological stability to a user. To this end, an additional auxiliary lift unit is installed, which, when a lift column moves up and down, automatically moves a middle column up and down in conjunction with an up and down movement of an upper part column, so as to prevent an unstable up and down movement or a shock due to a fall of the middle column, thereby preventing malfunction and breakage of a lifting object and an accident.

    본 발명은 기계장치의 높낮이를 조절하기 위한 전동식 리프트 칼럼에 관한 것으로, 더욱 상세하게는 리프트 칼럼의 승하강 작동시에 상부칼럼의 승하강 작동과 연동하여 중간칼럼을 기계적으로 승하강시키는 별도의 보조 승강장치를 설치하여 중간칼럼의 불안정한 승하강이나 낙하에 따른 충격을 방지하여 리프팅물체의 고장과 파손을 방지하고 안전사고를 예방하며, 사용자에게 심리적인 안정감을 제공하여 더욱 안전하고 원활하게 작업을 할 수 있도록 한 전동식 리프트 칼럼에 관한 것이다.
