1 is a schematic block diagram of a conventional drop lift equipment.

Referring to FIG. 1, the drop lifting device disclosed in the prior art No. 10-0747158 includes four vertical columns 10 installed in an upright fixed state, and an upper frame (not shown) for connecting upper portions of the vertical columns 10 A sliding guide 30 provided on the vertical columns 10 and a cage 40 connected to the sliding guides 30 to move up and down and a conveyor 50).

However, since the conventional drop-lift equipment consumes the regenerative power generated during deceleration or braking as heat energy, a braking resistor and a braking unit are separately required to consume the regenerative power. Therefore, the braking resistor and the braking unit There is a problem that the regenerative electric power can not be recycled.
