The controlled free fall offers positive down control of a load at selected speeds and may be controlled anywhere on the way down by modulating the volume to metering pump The controlled free fall is not designed nor intended to lower the maximum load in a controlled free fall mode The permissible load is 3096 of the maximum line pull capacity of the winch Since the clutch release pressure of the controlled free fall varies in accordance with the size of the load a metering pump is utilized to compensate for clutch release pressure variations FUNCTION OF CONTROLLED FREE FALL The controlled free fall has the same basic function as the emergency free fall with the addition of a metering pump which regulates the different clutch pressure requirements during a controlled free fall When the controlled free fall is actuated hydraulic pressure is channelled into the clutch piston causing the clutch piston to press against a series of springs and release the multi disc clutch When the clutch has been released the final planet assembly rotates with the cable drum around a stationary sungear A small hydraulic gear pump is splined to the final planet hub This hydraulic pump displaces hydraulic oil flow out of the free fall control circuit to compensate for the difference in the clutch release pressure which varies according to the actual lowering speed The faster the load is lowered with the free fall control the faster the planet hub will cause the p
