Duratorque is a superior suspension system that is suitable for fitment to and use on all types of trailers. Using specially formulated rubber cords as a springing medium, Duratorques are totally self-contained and easily fitted to the trailer chassis. Because the two sides are not connected, each wheel is independently sprung.
All Duratorque components are either galvanised or electro zinc plated for protection against corrosion.
From July 2011, 1000kg to 1750kg versions are fitted with a bolt in replaceable stub axle.
Carrying capacities for duratorques are 1000kg, 1500kg, 1750kg to 2200kg in both two piece and full beam types and 3000kg version in full and drop beam. These capacities are for single axle applications. When mounted in tandem the capacity must be reduced by 25% i.e. two 1500kgfull beam duratorques will carry 2250kg. Note that duratorque half axles are each labeled with the total capacity per pair, not each side.
All duratorques are able to be fitted with non braked or braked hubs. These brakes can be hydraulic disc, 1500kg, 1750kg, 2200kg & 3000kg capacities or Electric drum brakes in 1500kg, 1750kg & 2200kg capacities and hydraulic drum brakes in 1250kg capacity.
It is recommended that Duratorques be mounted to the trailer with the swing arms trailing. When mounted in tandem the distance between the tyres be kept to a minimum and should not exceed 150mm. The distance between the top of the tyres and the mudguards when the Duratorques are new and unloaded should be at least 120mm. When mounted in tandem the front axle should be braked.
When ordering full beam Duratorques remember to supply your required length measurement A & B as shown in the diagram below.
