A combined fork arm of a forklift is mainly composed of fork arm combinations, fork arm sets, a fork arm combination lifting device, a fork arm combination pushing device, a fork hanging block and a control system and used for forking and carrying box type objects and bagged objects with no fork inserting space below. Each fork arm combination is formed by connecting one fork handle with one to four fork arms. Each fork arm set is composed of two fork arm combinations. One forklift is provided with two fork arm sets. Each fork arm combination comprises a lifting device and a pushing device which form an independent set. When goods are loaded in a forked manner, wedge openings in the front ends of the fork arms of one fork arm combination in each fork arm set are inserted in a small gap on the lower edge of the goods firstly and conduct lifting to pry and expand the gap; and the fork arms of the other fork arm combination in each fork arm set are instantly inserted to the expanded gap, and the fork arms alternately pry the gap to be inserted therein. After the fork arms are inserted in the gap, the fork arms of two fork arm combinations in each fork arm set alternately rise to lift the goods and stand still, fall, advance and rise till the fork arms are inserted to the lower edge of the goods in a penetrating manner. In the unloading process, the fork arms of two fork arm combinations in each fork arm set alternately lift goods and stand still, fall and retreat till the goods fall to the placing position.
