3. Structure
1) Beds (bottom columns) and Vibration Proof Device
Alternator is coupled directly with engine and they are installed on the bed through vibration proof
device (Rubber Pad and Angle).
2) Low Noise Sound-Proof Enclosure (Bonnet)
The structure is that the inside of the bonnet is sound-proof treated and you can lift up the
alternator and the engine together with the beds by using a lifting lug.
