According to an embodiment of the present invention, there is provided a hand lift device including: a frame portion including a vertical frame, a first sprocket installed on an upper end of the vertical frame, and a second sprocket installed on a lower end of the vertical frame; a chain installed to engage with the first sprocket and the second sprocket; a cargo loading unit which is connected with the chain and disposed to be liftable along the vertical frame to load cargo; a power transmission portion which provides a driving force to the chain so that the cargo loading unit is lifted up and down; a sensor portion which is installed in an area where the frame portion is formed to be positioned at an upper side in a range where the cargo loading unit is lifted up and down and includes a proximity sensor to sense the cargo loaded on the cargo loading unit; and a controller which controls lifting up and down of the cargo loading unit by adjusting the driving of the power transmission portion according to a sensing signal from the sensor portion.

According to the embodiment of the present invention, since the operator can automatically load the cargo by controlling through the cargo loading unit without manually loading the cargo, the hand lift device can operate faster than manual operation, load more cargo over the same time, and operate with a small number of persons, thereby reducing the cost.

A swivel base is provided on a trolley so as to be able to swivel around a vertical axis, and a fork can be slid in a horizontal direction between an advanced position and a retracted position by a sliding mechanism capable of moving up and down along a pillar erected on the swivel base. Thus, it is possible to realize a configuration in which an empty-box skid is loaded in one direction and unloaded in another direction by means of the swiveling swivel base, without employing a configuration in which a plurality of members is supported so as to be able to swivel around different vertical axes. A movable range of the sliding mechanism (a movable range of the fork) in a vertical direction is therefore not significantly limited, and a transfer position of the empty-box skid in the vertical direction can be set to a lower position.
