Control systems for tractors lateral stability.
The system is used for the determination of the lateral stability as well as the determination of the torque of inertia of tractors. The tractor reception platform can be operated in two different ways:
a) Rotating the platform around the elongate achse at the side of the platform for the determination of the tractor lateral stbility.
b) Lifting and oscillating the platform for the determination of the tractor torque of inertia.
All the system movements are hydraulic, and the results are displayed and recorded with a help of a PC.

In front of the five metal grates of the water entrance of the pumping station DP2 moves a metal raddle with a vertical 7 meter route, cleaning every grate separately from the material which is collected in front of it.
The raddle transports and disposes the material in a vat on the barrow in which the raddle and all system's mechanisms are placed.
The barrow moves in the roof of the pumping station bringing and disposing automatically the material of every grate at the end of its route.
The whole cleaning process is automated and is being executed either periodically or when the difference of the water's level before and after the grates reaches a predefined height.
All the system's movements are hydraulic.
