PURPOSE:To provide a lift conveyer which can eliminate the need of a vertical frame by connecting between a lower loading frame and a transfer frame fixedly supported on the ground with an endless chain, and supporting a plurality of hanging carriers on the chain. CONSTITUTION:In the case where lift is increased, and a chain is added, a movable frame 8 is retreated to let loose a chain 10, and then an additional chain on which carriers 20 are supported by predetermined pitches is added to the chain 10 so as to extend the chain 10. After that, the movable frame 8 is again projected to the left to again retain the extended chain 10 in a state of tension. In case of lowering a frame 1 as the ground 38 is excavated and removed, augers 37 are simultaneously driven to be buried in the ground 38 simultaneously. Thus, support legs 36 reach the next ground surface. |
