After the cargo is transported, the first driving member drives the fork plate to rotate to a vertical position, so that the entire fork plate is close to the push plate, reducing the horizontal area occupied by the fork plate, thereby reducing the footprint of the entire forklift.

[0029] 2. During forklift transport, the cargo abuts against the push plate, which helps position the cargo. When transporting small cargo, the compensating plate can be removed to reduce the area of ​​the entire push plate, thereby minimizing the floor space. When transporting large cargo, the compensating plate can be installed to accommodate cargo of varying sizes.

[0030] 3. The reinforcing rod increases the structural strength between the fixed and movable tines.
