To reduce dynamic loads in the hydraulic drive of the boom lift mechanism of the timber truck manipulator during loading and unloading operations, it has proposed to connect an additional hydromechanical damper. Based on the calculation schemes for the boom lift mechanism and damper, a mathematical model has compiled. Graphs of the time dependence for the boom lift angle, pressure in the pressure pipeline and the plunger stroke of the damper have obtained.
