Sakai PM550D roadbed stabilized soil mixer

This machine is mainly used for the improvement of poor soil and soft ground. The rotor of the working device is a direct drive method driven by a hydraulic motor to improve the power transmission efficiency. Because only the hydraulic pipes for transmission are used on both sides of the rotor, the side clearance can be reduced and the left and right can be moved by 600mm to ensure the construction to all parts. The rotor is continuously variable and its speed can be adjusted according to the soil conditions. When the load is small, the rotor turns to turn downwards for cutting. For better mixing performance, the rotor can be mounted backwards for upward turning cutting. On the basis of reducing engine noise, measures have also been taken to reduce operational noise, such as the use of rubber materials for housings such as rotor covers; and to prevent impact sounds while preventing flying debris. The driver's ear noise can be reduced to 73.5dB (A). In order to facilitate the post-operation cleaning, the aircraft is also equipped with air compressors, gas tanks and air guns. The stable soil mixer according to the severity of the load, the operation speed is different, the speed is 3 ~ 5m/min at light load, 2 ~ 4m/min in the medium load, 1 ~ 3m/min in the heavy load.
