(1) Driving device : It is composed of motor, reducer, chain transmission device, etc. The geared motor has high transmission efficiency, low noise, long service life and stable and reliable operation.

(2) Chain transmission device : equipped with chain tensioning mechanism and mechanical overload protection mechanism. The mechanical overload protection mechanism adopts a safety pin structure.

(3) Guide device : The guide device of the grill is composed of guide wheels, which are placed on the upper and lower parts of the two sides of the frame respectively, and its main function is to change the running direction of the grill rake.

 (4) The drive shaft has sufficient strength and rigidity to withstand the load acting simultaneously with bending moment and torque; the motor current is suitable for 380V , three-phase, 50Hz , and the rated power of the motor is 10% larger than the actual power consumption .

The sewage treatment mechanical grille is composed of a support frame, a driving device and a differential mechanism, an unloading mechanism, a cleaning grab ( rake tooth ) , a guide rail and a drainage groove, a grille frame, a maintenance platform, and an electric control device. It is driven by two independent brake motors, the lift motor and the control motor. The drive rotating device installed on the top steel frame of the whole machine is provided with three cable drums. The drum rotates under the drive of the lift motor, and the control motor matched with the lift motor drives the cantilever roller mechanism to move, and controls the middle control wire rope to open or close the grab. The grill is equipped with a heavy-duty high-capacity "grab" rake.

 Equipped with a safe and noiseless discharge mechanism with counterweight for cleaning up the dirt lifted by the grab bucket. Its unique articulated structure design prevents the grab bucket from being damaged due to overloading the unloading arm due to the heavy load during the lifting process. The grid automatic control can realize manual operation on site and provide remote control contacts. The electrical control also has emergency stop and various fault display and alarm functions.
