The invention relates to a combined-fork-arm type fork truck. The fork truck comprises a fork truck body, fork arms, fork arm groups, a fork arm lifting device, a fork arm pushing device, fork hanging blocks, and a control system. The fork truck is used for transporting box type and bag type objects with bottoms without fork insertion space. The fork arm lifting device consists of fork hanging blocks, standing sliding blocks, flat sliding ways, and lifting cylinders. And the fork arm pushing device includes flat sliding ways, guiding sliding ways, flat sliding blocks, motors, chain wheels, and wide chains. The wide chains are guided into the flat sliding ways; and thus the fork arms are pushed to move forward and backward. One fork arm group contains two fork arms; and two fork arm groups are installed on for fork truck. When one article is forked and transported, a wedge opening at the front end of one fork arm of each fork arm group is inserted into the little gap of the lower edge of the transported article and then the fork arm is lifted to expand the gap; and the other fork arm is inserted into the expanded gap immediately. The two fork arms lift the article without move, go down, move forward and then rise alternately until the bottom of the article is penetrated and then the article can be transported. During unloading, the two fork arms lift the article without any move, go down, and back off alternately until the article is placed at the placing point.
