FIELD: testing equipment. ^ SUBSTANCE: loading gear has base, upper and lower clamps and mechanical drive. Loading mechanism is made in form of one-frame construction, at base of which two or more hydraulic jacks are fixed, positioned normally to base, symmetrically to one another and to base center. Hoisting two-drive or one-drive screws of hydraulic jacks by upper ends are linked to beam. even movement of jacks pistons is adjusted by synchronizing gear by means of increasing or decreasing amount of working liquid fed into cylinders. ^ EFFECT: decreased mass and dimensions of construct. ^ 1 dwg |
