This third generation camera-mounting platform offers the following:
“Cross Roller Bearings” which, by their line contact, as opposed to the point contact of ball
bearings, and their increased length of engagement, multiply the stiffness of the D-Box III, and
allow smooth easy movement fore/aft and side/side.
Access to each of the four mounting screws at once, without the need to adjust the fore/aft or
side/side controls.
A “drop in/out” feature and an independent safety mechanism, so that in the event of a failure in
the locking mechanism, the camera is still secure when the safety lever is in place.
Tool-less rough adjustment of the camera, via the clamp lever located on the right side.
Quick change from hi to lo-mode.
Side/side and fore/aft controls on both the right and left side, for easy access regardless of the
mode you are operating in; high or low, or the side from which you operate; left or right.
Fine thread lead screws and captured lead nuts enable the operator to make small, accurate
adjustments.
Once the camera has been placed in the Donkey Box, lock the safety lever in place. Then,
ensuring that the clamp lever is in the up and locked position, tighten the locking screw, if this
screw is over-tightened the rough adjustment via the clamp lever will be defeated. For rough
adjustments to the camera’s fore/aft position first turn the clamp lever down (clockwise) then
push or pull to slide the camera into the desired position. Return the clamp lever to it’s locked
position and then use the controls on either side of the Donkey Box for final adjustments, fore
and aft and side to side.

Lubrication: Apply lubrication to the locking screw, and the bearings as dictated by shooting
conditions.
Cleaning: Wipe down the visible areas with a light solvent.
Tightening: Do not over-tighten the locking screw, this will defeat the function of the clamp
lever. Set-screws and bearing rails are locked to preset torques at the factory. In the case of any
type of field repair pay close attention to how these screws are put back into place, the preset for
the bearing rails is 17 lbf-in, while the preset for the set screws is 2.2 ozf-in.

Tension Adjustments: In order to adjust the tension or resistance in the knobs it is necessary to
use the D-Box III tool.
For
side/side adjustments it is necessary to first remove the side/side knob on the left side of the D-
Box. The knob is held in place by a set-screw, which is accessible through a hole in the
underside of the D-Box. It will be necessary to remove this set screw using an allen tool. Once
the knob has been removed slide the square-lug end of the tool over the shaft and tighten the
locking nut, while checking the side/side control for the desired tension/resistance.
For fore/aft adjustments use the wrench end of the D-Box III tool to access the locking nut. The
locking nut is located on the underside of the D-Box towards the fore/aft controls. Tighten the
locking nut while checking the fore/aft controls for the desired tension/resistance.
THIRD GENERATION: UPPER JUNCTION BOX
Overall, the upper junction box delivers power to the camera, the focus system and the video tap via your
cables. It is attached directly under the Donkey Box.

The PRO™ Gimbal’s design and construction guarantee a precise intersection of all three axes,
while the correct application of bearings provides a smooth, deflection-free pan, roll and tilt. A
locking mechanism achieves concentric clamping about the post, ensuring that all axes converge
at post center. The PRO™ Gimbal is compatible with all 1.5 inch center posts.
For various shot requirements, the gimbal can be moved easily up and down the post by
loosening the clamp screw, sliding to desired position and re-tightening. Once in place fine
adjustments may be made by turning the vernier ring located just below the grip. Approximate
range of fine adjustments is ½an inch in both directions.
FIGURE 6:
-DO NOT OVER TIGHTEN ANYTHING ON THE GIMBAL
I) When tilting the camera, the PRO™ Gimbal is designed to distribute the load of the
camera evenly between its two (2) radial side bearings. If you notice that one side of
the Gimbal yoke is tilting unevenly, the Gimbal yoke may be bent and need replacing.
It is unusual for this problem to occur unless the rig has been dropped or hit.
II) If the Gimbal appears to stick when panning, the pan bearing is most likely dirty
(especially if the operator has been working in very dusty conditions).
To clean, take the following steps:
1. Use the gimbal wrench to remove the outer retaining ring, (while the gimbal is clamped
on the post). Slide outer housing up the post.
2. Clean out the bearing with a non-residue electrical contact cleaner.
3. Re-lubricate with one drop of very light camera oil (ie: Arri Camera Oil)
4. Spin bearing to distribute oil. Re-assemble.

The Generation II system makes use of a quick connect/disconnect assembly at each end of the
post. Inside the post is a coiled cable consisting of (18) conductors all of which are terminated at
each end by a LEMO EGG.3B.856.CLM3 connector. The Generation II Center post does away
with the slotted inner post of the Generation I model. The slot is replaced by a pair of channels
running the length of the innerpost. By doing away with the slot, the Generation II Center post
maintains the rigidity of a fixed post without sacrificing the benefits of an adjustable post.

Located at the top center of the Lower Junction Box is a large 18-pin Lemo jack which provides
the electrical connection point for the Center post Assembly. The Center post Assembly
is attached to the Lower Junction Box as follows:
1. Insert the center post Lemo plug into the Lower J-Box Lemo jack.
2. Attach the post by threading the Locking Ring onto the Post Receiver.
The Generation II Center post utilizes a clamp lever system identical to that of the VZ Gimbal
and Gen III Battery hanger to lock the post at a specific length. To adjust the Center post length,
release the clamp lever and
extend the post to the desired length and close the lever. Maximum post length is 26” end to end.
