Abstract

The present invention relates to an industrial lift that is installed on one side of a structure to be able to lift or lowered a loaded product or a passenger by using a small amount of power. A main body can be lifted or lowered with a small amount of power as multiple pulley parts are installed to be able to reduce a load on a drive part. Also, work efficiency is maximized as a driver and a worker provide rapid and convenient movement. A moving path was long in a factory as stairways to an upper part are installed on both sides. However, access is facilitated as the lift is installed on a needing position. Also, the present invention can be installed simply in a general factory and accidents can be prevented as a guide bar is installed on one side of a structure and a roller part is configured to be able to move along the guide bar, so an object or a person can be lifted and lowered stably, swiftly and efficiently. The industrial lift comprises: a main body having a boarding space arranged therein; a guide bar installed vertically on a structure; a roller part moving along the guide part; a drive part for lifting and lowering the main body; and a pulley part for guiding a wire.

Description
