Turret rotation is carried out by a rotation hydraulic motor moved by a worm
screw on a bearing ring.
Turret could be rotated 180° each side till a mechanical block, achieving a total
rotation.

EMERGENCY GRAVITY DESCENT SYSTEM
Cylinders for 1
st
and 2
nd
booms, 3
rd
boom and jib are equipped with a coil valve
for gravity emergency descent, they are controlled by the control module when
the remote control button “gravity emergency descent” is pressed.
When they are fed they open a calibrated passage and under the gravity effect
(weight) they will allow oil to get out from the bottom of the cylinder flowing
back to the tank (through the ON-OFF valves), so that booms will slow down.
The coil valve for gravity emergency descent has a blue cap.
How to use and when to apply the emergency gravity descent is detailed on
the emergency procedures chapter 7.2.1.
