General

The low-noise version of the DP80/90 lift truck features, in addition to all the characteristics its standard version incorporates, noise reducing and deadening measures that ensure quieter environment during operation both around the truck and in the operator’s compartment. These measures include the following:

1. Aradiator cooling fan of improved air-blowing efficiency is used to reduce “voom” noise. 2. Noise damping material provided around the radiator at the rear of the engine-transmission compartment to effectively confine noise in the compartment. 3. Insulator-lined under cover is provided at the bottom of the engine-transmission compartment to impede propagation of noise. 4. The inside of the engine-transmission compartment is lined with noise damping material. 5. Noise damping material added to the area in front of the engine-transmission compartment helps confine noise in the compartment. 6. The engine cover having increased sound-absorbing performance effectively prevents engine-transmission compartment noise from reaching the cab through the top of the compartment. 7. The seat frame is designed to prevent the engine-transmission compartment noise and engine vibration from reaching the cab through the top of the compartment. The seat frame also serves as a cab mount. 8. The dashboard and cab floor use insulator to help prevent the engine-transmission compartment noise from reaching the cab through the top of the compartment. 9. The front surface of the front axle housing is covered with insulator to absorb the noise from the differential gear. 10.Acab is adopted to improve the operator’s acoustic environment. 11.The cab is equipped with a heater.
