FIELD: test engineering.
SUBSTANCE: loading mechanism has lower and upper clamp for samples, lever-type loading unit provided with bar and tray for weight, which loading unit is connected with upper clamp. Loading mechanism has frame mounted onto base. Three lower clamps are introduced additionally and fastened to lower part of frame. Three upper clamps are connected with two intermediate beams. Intermediate beams are connected with third beam through four control-rods. The third beam is connected with lower lever by means of two control-rods, frame and prism. Prism is fixed in groove of lower lever which has one end connected with frame through prism; the other end is connected with variable-lengthen control-rod through prism and frame. Variable-length control-rod has frame at the other end as well, which frame rests again prism fixed in groove of top lever, which rests against casing. The other end of top lever has prism fixed against which prism the frame rests which is connected with rod provided with tray for weights. Hinges connect samples with lower and upper clamps. Both ends of control-rods have cylindrical hinges.
EFFECT: improved efficiency of checking.
