The invention discloses a fork body machine tool and a fork loading machine for heavy-load stones. The fork body machine tool comprises a movable arm, a rocker arm, a fork body bracket, a fork body and a roller installed in the fork body. The movable arm is connected with the main machine and the fork body bracket, the rocker arm is connected with the fork body bracket through the connecting rod, and the fork body is hinged to the fork body bracket. The roller is installed in the fork body through a pin shaft, two ends of the pin shaft are fastened through baffle assemblies, the roller is of an inner and outer double-layer structure and comprises an inner roller body installed on the pin shaft and an outer roller body sleeved on the inner roller body, the inner roller body is in interference fit with the outer roller body, and the inner roller body adopts a composite bearing. According to the fork body machine tool, the friction force between stone and the fork body can be obviously reduced, and meanwhile the quality of blocks can be well guaranteed.
