RV PROFILE
If it ’ s an offroad or even a semioffroad caravan , there ’ s a good chance it will have independent coil suspension . For good reason .
Independent coil suspension absorbs massive forces imposed by varying road conditions . If it can ’ t do that reliably , it isn ’ t worth the steel it ’ s made from .
Alpha Suspensions has developed a range of Australianmade independent suspension systems catering for trailers of all shapes and weights from 1600kg to 4400kg .
A quality suspension setup will comprise components tuned to suit the weight and intended use of the caravan . To that end , Alpha has produced the Ultra semioffroad system as well as the Extreme offroad system . Both are independent coil systems with trailing arms , offering points of difference worth considering for your next caravan / trailer purchase .
Alpha Suspensions has developed its own unique bump stops .
In terms of ride comfort , a quality coil setup should efficiently absorb the vibration , gravitational and impact forces from the road . And while leaf-spring systems have their place , a coil setup rides better – the spring rate can be controlled more accurately , with the dampening done hydraulically in a shock absorber instead of by inter-leaf friction .
It is essential that a coil suspension system maximises friction between the tyre and road surface , maintaining that contact consistently .
