FIELD: testing engineering. ^ SUBSTANCE: hydraulic V-shaped grip comprises housing, piston, and clamping units made for permitting movement in the axial direction by means of the piston over the surfaces inclined to the axis of symmetry of the grip. The wear proof member is interposed between the piston and clamping units and provides radial movement of the clamping units over guiding surfaces arranged symmetrically to the axis of symmetry of the grip. ^ EFFECT: enhanced precision of testing. ^ 2 cl, 1 dwg |
