Influence of geometrical and kinematic parameters of the kinematic scheme of the mechanism of working body of a loader of type PNB on increase in theoretical productivity depending on position of the area of capture of cargo is shown and the analysis of change of speed and acceleration of an extreme point of working body of a paw for one turn of a crank is given.
The article deals with the position control lever transmission ratio of the traction mechanism with adjustable resistance to movement as a function of pressure from the driving wheels on the rails.
