Devon based suspension specialist Hydrapowered has developed a retro-fit hydraulic system to improve trailer stability on steep slopes and at speed.
The company first developed the Height and Load Adjustable Hydraulic Suspension Cylinder in order to, adjust the height of a trailer to suit the vehicle towing it. They looked at various ways of adjusting the trailer towing height but decided the hydraulic route was best. Consequently they designed a suspension system that fitted inside a double acting hydraulic cylinder.
It has a self-contained two-cylinder hydraulic circuit for each axle, which is able to limit the variation in leaf spring flex so that one side of the trailer cannot drop or rise any more than the other – if one spring goes up, then the other one does, too.
The system can be supplied in kit form and fitted to an existing trailer. The kit is a closed hydraulic system consisting of two ‘Hydrapowered’ suspension cylinders, two hydraulic hoses, along with fittings and brackets on each axle. There are no electronics, pumps or valves so maintenance is minimal and prices start from £650.00 per axle.
