Abstract
A multi-process machine suspension device is equipped with two hydraulic cylinders for rotating the machine relative to an arm supporting it. One cylinder is pivoted to another arm and the other cylinder to the machine frame. Both cylinders are pivoted by one end to a freely rotating intermediate arm pivoted to the same frame joint as the arm supporting it.

A felling head for a multi-process machine for felling and further processing trees, arranged to be suspended on the boom of a loader via a joint, said multi-process machine including a rotator for rotating it, a suspension device, an actuator unit and its frame connected to said suspension device for felling and further processing trees, said suspension device including
- an arm for the suspension device, connected to said rotator, and a transverse frame joint in its bottom part for supporting the frame of the actuator unit, and
- one hydraulic cylinder is pivoted at one end to said arm for the suspension device to rotate it relative to the frame for turning the actuator unit to felling and processing positions,
- a freely rotating intermediate arm having first and second ends forming a joint spacing there between and pivoted to said frame joint at the said first end, and
- another hydraulic cylinder pivoted at one end to the frame of the actuator unit and wherein both hydraulic cylinders are pivoted at their other ends to the second end of said intermediate arm.
