- rigid connection of the accelerating drive of the machine frame reinforces the impact loads during acceleration aggregate frame to the frame of the machine and the staff and worsens the conditions of his work;

- performance drive with acceleration in the form of a hydraulic cylinder limits the rate of aggregation of the frame due to the limitations of the speed of movement of the piston, connected to the thrust element, and reduces the efficiency of operation of the machine;

- Alicia second drive with acceleration in the form of a hydraulic cylinder with a reduced stroke and thrust element complicates the design of the machine.
