The invention discloses a heavy plate fork, and aims to provide a heavy plate fork which can effectively improve the structural compactness of the heavy plate fork and reduce the thickness and occupied space of the plate fork under the condition that the structural strength and stability of the plate fork are not affected. The device comprises a fixing assembly which is provided with a plurality of fixing rollers; the connecting assembly comprises a guide rail extending in the telescopic direction of the heavy plate fork; the driving assembly drives the connecting assembly to stretch out and draw back relative to the fixing assembly; a plurality of upper fork rollers are arranged on the upper fork assembly; the multi-speed connecting mechanism comprises a chain for connecting the fixing assembly and the upper fork assembly and a chain wheel which is arranged on the connecting assembly and is meshed with the chain; guide grooves are formed in the inner and outer sides of the guide rail, and storage grooves are formed in the upper and lower sides of the guide rail; the fixed roller is arranged in a guide groove on one side of the inner and outer sides of the guide rail; the upper fork roller is arranged in the guide groove on the other side of the inner and outer sides of the guide rail; and the chain is arranged in the storage groove of the guide rail.
