R3Hanging rotators, also referred to as Cardanic Mount rotators, hang from a boom or a flat plate coupler via an "H-style" full hanger, which has two pins at 90 degree plains. This allows the grapple/rotator system to swing in any direction, so the stress of the load is always straight down on the rotator. This way, the rotator housing doesn't crack from "twisting" load stress.

Rotator Vanes VALBY® hanging rotators are "Vane" rotators. Inside the rotator, a series of metal plates called vanes are embedded sequentially around the axle. When the hydraulic oil is pumped into the chamber around the axle, the oil pushes against the vanes, turning the axle. If the direction of the oil is changed, so changes the direction of axle rotation. This system is low-cost, efficient and perfectly suited for hanging grapples used on small- or medium-sized excavators.

Typical applications include log loading, scrap & material handling and any kind of lifting that only requires grabs from above.

The key factor determining the correct combination of grapple and rotator for your application is the operating weight range of the base machine. For help determining the right rotator for your application, call us at
