For the drum generate in cellular concrete mixers A4VTG071, A4VGT090 series.
-Variable axial piston pump of swash plate design for hydrostatic drives in closed circuit
-The stream is proportional to the generate velocity and displacement.
-The movement will increase as the angle of the swash plate is modified from zero to its highest price.
-Stream path alterations effortlessly when the swash plate is moved through the neutral place.
-Two force-relief valves are presented on the large force ports to safeguard the hydrostatic transmission (pump and motor) from overload.
-The higher-strain relief valves also purpose as boost valves.
-The built-in improve pump functions as a feed pump and handle pressure supply.
-The optimum boost pressure is restricted by a built-in boost stress-reduction valve.
-Tapered shaft option for direct travel shaft yoke installation.
