The present invention relates to an electric-powered safe trolley of prevented fall type provided with a trolley body having a horizontally laid rectangular frame shape. Left and right electric motors are fixed to the center of the inner side of the trolley body, and a plurality of rollers are connected to the electric motor for gear linkage in each of the front and rear of the left, right, and both sides of the inside of the trolley body. A driving force from the left and right electric motors is transmitted to the roller for electric-powered rotation and rolling. Provided on the left, right, and both sides of the front and rear side portions of the trolley body are a trolley portion where front and rear auxiliary rollers respectively protrude forwards and rearwards and outwards at a predetermined interval from the ground surface and a base plate horizontally fixed to the upper portion of the middle portion of the trolley body. The upper surface portion of the base plate is provided with a ring-shaped bearing insertion groove. The bearing insertion groove has an inserted and fixed oilless bearing that has a ring-shaped plate. The upper surface portion of the oilless bearing is provided with a mounting portion where a mounting plate is placed to be rotatably installed and an indicating portion casing fixed at a predetermined interval from the ground surface in the front surface portion of the trolley body. A battery for power supply is incorporated inside the indicating portion casing, and a direction indicating portion equipped with a laser pointer is provided on both left and right sides of the front of the indicating portion casing so that the traveling direction of the trolley portion is indicated by means of laser beam emission toward the forward ground surface.

    본 발명은 수평으로 눕혀진 사각틀형상의 트롤리몸체가 구비되고 트롤리몸체의 내측 가운데부분에는 좌우측 전동모터가 고정설치되며 트롤리몸체의 내부 좌우양측 전후방에는 각각 복수개의 롤러가 전동모터와 기어연동되게 연결설치되어 좌우측 전동모터로부터의 구동력이 롤러에 전달되어 전동식으로 회동되면서 구름이동되되 상기 트롤리몸체의 전,후면부 좌우양측에는 각각 지면으로부터 일정간격 이격되게 전,후방보조롤러가 전후 외측으로 돌출되게 설치된 트롤리부와, 상기 트롤리몸체의 가운데부분 상부에 수평으로 고정설치되는 베이스판이 구비되고 베이스판의 상면부에는 링형상의 베어링삽입홈이 형성되어 있으며 베어링삽입홈에는 링형상의 판으로 된 오일리스베어링이 삽입되어 고정설치되고 오일리스베어링의 상면부에는 적재판이 올려져 회전가능하게 설치되는 적재부와, 상기 트롤리몸체의 전면부에 지면으로부터 일정간격 이격되게 고정설치되는 지시부케이싱이 구비되며 지시부케이싱의 내측에는 전원공급을 위한 배터리가 내장설치되고 지시부케이싱의 전방 좌우양측에는 전방 지면을 향해 레이져빔을 조사하여 트롤리부의 진행방향을 표시하는 레이져포인터가 설치된 방향지시부로 구성된 것을 특징으로 하는 전도방지형 전동안전트롤리에 관한 것이다.
