The fork for manipulation with loads mainly with boxes (12) or packets (13) of regular geometric shape consists of a pair of support mandrels (1), each of which is mounted on its own base plate (2) connected with a frame of a telescopic mechanism of this fork by means of a joint (4). The purpose of the solution is to achieve higher functional reliability of the fork with concurrent insignificant increase of production complicacy. The solution consists in the fact that each base plate (2) with the support mandrel (1) is via a displaceable connection (5) attached on one end of its control lever (6). The second ends of the control levers (6) are connected by means of a joint connection (7) and a displaceable sleeve with a frame (3). Both levers (6) are in the central part attached by means of joints (8) to each of the ends of a connecting support (9), which is in its centre equipped with vertical guiding column (10) displaceably arranged in the frame (3), as well as with a catching nose (11). Between the frame (3) and an adjustable stop piece (14) positioned on the top of the guiding column (10) there is a flexible element (15).<IMAGE>
