The Equalizer is a new damping system for spread axle trailers from Talbert Manufacturing in the USA.
It is a nitrogen-assisted system that hydraulically transfers loads in all terrains. The system oscillates around a central self-tracking pivot point to provide proportionate weight distribution in each axle grouping, regardless of varying road conditions, according to the manufacturer.
The Equalizer is available for Talbert 55 and 60 US ton (50 and 54 tonne) 55SA and 60SA 3+1 spread axle series trailers and axle attachments. It allows a 14 foot 1 inch (4.3 m) spread with 54 inch (1.4 m) axle spacing and a 14 foot 7 inch (4.4 m) spread with 60 inch (1.5 m) axle spacing.
It is designed for operators to make easy and quick adjustments and to maintain those settings to safely maximise loads. By hydraulically damping axle movement and controlling load transfer, the system absorbs hauling and loading shocks to allow more suspension movement for reduced stress and a smoother ride.
A dual two-speed landing gear is used to make connecting the trailer to the axle attachment easier. The axle attachment can be lifted for reversing. No shimming is needed so time is saved and the booster and attachment can be left on when running empty.
