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.
SINGLE AXLE OR TANDEM.
If Tandem then the carrying capacity of each Duratorque is to be reduced by 25%
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 1500kg full 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 & C as shown in the diagram below.
