The components that keep a fleet on the road
Air, Mechanical & Bogie Suspensions
Air · Mechanical · Bogie
Air and mechanical suspensions in American and German standards, drum and six-spoke bogies, and the Argo bogie. Choosing between air and mechanical depends on load sensitivity, road condition and maintenance cost — not on purchase price alone.
Suited to
- Shock-sensitive freight
- Long-haul road fleets
- Multi-axle heavy trailers
- Suspension refits on existing fleets
