The StoneVac 405 has been developed in-house based on the MRTA6 featuring Quadra-Lift technology.
This means that the force needed to tilt a load is less than half that typically required for a lifter that pivots around a single point. When a load is tilted to either the upright or the flat position, the lifter maintains the load automatically without using latches.
The dual-circuit StoneVac 405 also features 360° continuous manual rotation as well as moveable pads and extensions arms that can accommodate a variety of load sizes and shapes.
