The invention provides a lightweight combined fork arm vehicle. The lightweight combined fork arm vehicle is mainly composed of a vehicle body part, a lift arm rest part and a combined fork arm part. A lift mechanism composed of a main arm and a movable arm is installed on a vehicle body. The combined fork arm part is composed of fork fingers, fork arms, fork arm joints, fork arm joint lifting mechanisms, fork arm joint pushing mechanisms and a hanger. Objects can be forked and carried no matter whether pallet fork insertion space exists below the objects or not. A trolley is provided with two form arm sets. Each fork arm set is composed of two fork arm joints. Each fork arm joint is provided with one independent lifting mechanism and one independent pushing mechanism. When the objects without space below are forked, the fork fingers at the front end of one fork arm joint of each fork arm set are firstly inserted into gaps below the carried objects. The fork fingers are lifted upwards, and the gaps are pried off and expanded. The fork fingers of the other fork arm joint of each fork arm set are immediately inserted into the expanded gaps. The two fork arm joints of each fork arm set alternately rise to lift the goods to stand still, descend, move forwards and ascend till the two fork arm joints are inserted into the portions below the goods, and then the goods can be carried. In the unloading process, the two fork arm joints of each fork arm set alternately lift the goods to descend and retreat till the goods fall at stacked positions.
