Abstract: The dependence of braking time on pusher’s tappet rod downstroke time when using magneto hydraulic pusher as a drive gear in braking systems of lifting-and-shifting machines has been analyzed in the work. There has been offered a magneto hydraulic pusher of original design, in which the time of tappet rod lowering in emergency situations doesn’t depend neither on opening of valve regulating tappet rod downstroke time, nor on attraction force caused by residual magnetism and electric power supply to the magneto hydraulic pusher. This fact makes it possible to increase tappet rod downstroke speed to the maximum. Use of the mentioned magneto hydraulic pusher as a brake actuator of lifting-andshifting machines allows to attain both smooth braking of any degree and instant braking in emergency situation.
