Coil Spring
A fixed seat transmits
Coil spring suspension is capable of dampening vibrations in the 4 to 15 Hz range, effectively suppressing mild to harsh shaking.
Coil spring suspension can also be manually adjusted to accommodate the weight of the driver.
The
Air Suspension
Air springs extend the capability of the suspension into the 2 to 3 Hz range. For tractors, this is also the range of trailer- induced bouncing, the main reason for poor ride comfort. Air spring suspension is therefore a particularly effective solution for such bouncing.
Also available are air suspensions that automatically adjust to the driver's weight. The driver needs only to adjust the seat height.
