The present invention relates to a working lift which employs a new structure to lift a worker and materials up and down reliably. According to the present invention, the work lift includes a support (A) and a lift platform (B) coupled to the support (A) in a liftable manner. The support (A) is formed in the shape of a box which has an open upper part, a guide rail (11) extended in a vertical direction, and a rack gear (12). The lift platform (B) includes: a lift platform body (20) including a support wheel (21) adhered to the guide rail (11) and a pinion gear (22) coupled to the rack gear (12); and a driving unit (30) which is arranged on the lift platform body (20) and rotates the pinion gear (22) in normal and reverse directions. Accordingly, the work lift has a simple structure, is lightweight, and enables the driving unit (30) to rotate the pinion gear (22) in normal and reverse directions to execute a reliable lifting operation while the lift platform (B) is supported on the guide rail (11) of the support (A).

    본 발명은 작업자와 자재를 안정적으로 승강시킬 수 있도록 된 새로운 구조의 작업용 리프트에 관한 것이다. 본 발명에 따른 작업용 리프트는 지지대(A)와, 상기 지지대(A)에 승강가능하게 결합된 승강대(B)로 구성되며, 상기 지지대(A)는 상면이 개방되며 내측면에는 상하방향으로 연장된 가이드레일(11)과 랙기어(12)가 구비된 박스형태로 구성되고, 상기 승강대(B)는 상기 가이드레일(11)에 밀착되는 지지휠(21)과 상기 랙기어(12)에 결합되는 피니언기어(22)가 구비된 승강대본체(20)와, 상기 승강대본체(20)에 구비되며 상기 피니언기어(22)를 정역회전시키는 구동유닛(30)으로 구성된다. 따라서, 구조가 간단하고, 가벼울 뿐 아니라, 상기 구동유닛(30)으로 피니언기어(22)를 정역회전시키면, 상기 승강대(B)가 상기 지지대(A)의 가이드레일(11)에 지지된 상태로 안정적으로 승강되는 장점이 있다.
