This device is installed by the user with vertical movement of the chain, next to which the user moves horizontally.
In a chain hoist (chain trolley), the horizontal movement is done by a 3-meter chain. This chain is pulled vertically to the sides and causes the trolley to move in the direction of the rail (beam).
Manual hoists can be used to move heavy objects vertically.
However, due to the basic structure of manual hoists, only vertical movement of objects by these hoists is possible. But suppose we also want to move objects horizontally in a certain direction. To do this, it is enough to connect the manual hoist to a moving rail (moving trolley), then you can easily move the objects both horizontally and vertically.
