Figure 1
To achieve more accurate pressure vs. load charts for your exact trailer suspension place self-steer
axle on certified scales under the lowered steer axle and adjust the pressure regulator by 10psi
increments to adjust gauge pressure and record the load on the scales at these pressure
increments. This should give more accurate table results for each specific axle on your trailer. Make
sure the axle is at the ride height that it will be riding at when riding down the highway. See
Figure 1 for illustrations.
For SPIF trailers weigh the load on the primary axles and divide the load by the number of axles.
Next weigh the load on the steer axles and divide by number of axles. Then adjust proportional
pressure regulator to steers until each steer axle has same load on them as each primary axle and
therefore they equalize. All axles must equalize to within 500kg. See SPIF Vehicle and Weight Limits
manual for more information. Below in Table 2 the ParaMax suspension parameters for each ride
height is shown. These numbers can be used to verify that the suspension components are
operating within their allowable ranges.
