SUBSTANCE: locking-fixing device of turning gear consists of holder and spring, of piston pneumatic cylinder, outlet end of rod of which is connected to turning gear. In the rod of the pneumatic cylinder there is made an axial orifice wherein there are installed a spring and a holder with a piston. The holder has an axial orifice and a radial orifice connected to it for admission of compressed air. At the end part of the rod there is installed an eye with a through axial orifice and radial orifice coaxial to the holder and facilitating interaction of the eye with the holder. The rotating eye is installed in a support. An axle is arranged in the through axial orifice of the eye. The axle is stationary connected with the support and has an axial orifice wherein there is installed a connecting pipe for admission of compressed air. The rotating eye also has the radial orifice connected with the axial orifice and coaxial to the holder and a guiding groove facilitating interaction of the axle and the holder. Additionally, the eye is connected to the turning gear by means of a lever and a pressure plate.

EFFECT: expanded functionality of device.
