Rear Carriage Tilt Cylinder
Description
Fig. 6-14: Rear Carriage Tilt Cylinder
Two rear carriage tilt cylinders are located at the rear of the outer boom
section, one on each side. These cylinders maintain the attachment tilt
position as the boom is raised and lowered. As boom elevation changes, a
specific amount of oil in the cylinders moves to the front carriage tilt
cylinder, automatically adjusting the attachment tilt.
