The new semi-active suspension retrofits in 7020, 8010, 8020, 9000*, and 9020 Series Wheel Tractors and provides superior ride quality over conventional air suspensions. Comfortably operate your equipment at higher ground speeds while increasing productivity and reducing fatigue.
How it works
The semi-active suspension contains air suspension components with two important additions – a cylinder containing Magnetorheological (MR) fluid and a controller. These components electronically dampen the ride by exposing the MR fluid to a variable magnetic field around the piston orifice. This changes the viscosity of the fluid and thereby assists the air suspension with dampening. The suspension also contains new fore, aft, and lateral isolators that offer significant improvements in vibration isolation and end-stop control.
The self-contained, semi-active seat suspension can be installed in approximately one hour and uses the vehicle’s original seat top.
