SV-Shocks produces unique shock absorbers with axle lift function for trucks and trailers. This product works as standard shock absorber in normal conditions. When needed to lift the axle up, oil pressure is applied to the hydraulic connection at the lower end of the shock absorber. With this hydraulic pressure the shock absorber is compressed to its minimum length. The lift shock absorber is designed to lift the axle up only when the air pressure in the air springs of the same axle is released. Axle lift shock absorbers are normally used with air suspension axles.
We have large variety of hydraulic pump units for vehicles without hydraulic output. Our pumps are specially built for axle lifting systems. Pump units can be controlled by vehicles CPU or it can work as stand-alone system with integrated controller and safety functions. There are pumps available to lift one or two axles simultaneously or independently.
We have also built bigger XXL axle lifting shock absorbers for vehicles with coil or leaf spring suspensions. These can be used to lighten axle load or even to lift up the axle. This damper type is specially built to each vehicle type separately. Please contact us in your needs.
Benefits of SV-AXLS axle lifting shock absorber
- For OE installation, no separate lift cylinders or bellows are needed for axle lifting
- Saves space and weight compared to other ways to lift the axle
- Axle lifting shock absorbers can typically be installed using the existing brackets
- Lifted axle can also be used as a balance counterweight
- Saves tire costs and fuel when driving without a load and axles raised
- Reduced turning radius
- Allows easy turning and maneuverability in difficult conditions (narrow roads, deep snow…)
- Can be used for lowering light transport vehicles, like vans, if properly designed suspension mounts are used.
Important properties of axle lifting shock absorber
- Lifting capacity 1900 kg (4800 kg for XXL)/ shock absorber at maximum pressure (200 bar)
- Maximum static load capacity is 60 kN.
- Damping characteristics are the same as in standard shock absorbers we produce for similar vehicles.
- Minimum and maximum lengths are slightly different than in standard shock absorbers,because some internal parts have been added in order to create the lifting function.
- Because minimum and maximum lengths are different, it is important to check that the axle lifting shock absorber does not limit the suspension travel.
- Air pressure from springs of the lifted axle must be released before the axle lifting shockabsorber starts to lift the axle.
