instructions
Weight 2.2 kg (4.9 lb)
1.2 Safety precautions
Installation and setup should only be carried out by qualified and
authorized personnel observing the valid national Rules for the
Prevention of Accidents (RPA).
It is the responsibility of the person installing the assembly to ensure
that the suspension/fixing points are suitable for the intended use.
Always carry out a visual and functional inspection of the items
before use. In case there is any doubt as to the proper functioning
and safety of the items, these must be withdrawn from use
immediately.
All system components must be inspected for faults before use.
Damaged components must be withdrawn from use immediately.
Please also refer to Þ Chapter 1.7 "Care and maintenance"
on page 8.
Load safety information
The maximum permitted load of the Rota clamp is 500 kg/1100
lb. No additional loads must be added.
Never fit the clamp at any other angle than straight down.

1.3 Intended use
The Rota clamp must only be used to suspend d&b loudspeaker
cabinets from a single suspension point in connection with
applicable d&b rigging accessories. The Rota clamp allows the
load to be attached to overhead bars or truss with a tube diameter
of up to 70 mm (2.75”).
Note: Observe the maximum permitted load of the respective
accessories as indicated in their respective mounting
instructions.
1.4 Assembly
Fitting to Flying adapter/Flying frame
The desired position in the rig as well as the total vertical angle of
the assembly should be defined in advance. The total vertical
angle can be set using the hole grid of the respective flying
adapter or frame.
Proceed as follows:
1. Unlock and remove the ring cotter [1a] of the fixing bolt and
remove the fixing bolt [1b].
2. Attach the clamp to the respective hole of the flying adapter or
frame.
3. Insert the fixing bolt [1b] and secure the bolt with the ring
cotter [1a].
4. Recheck your work and ensure the ring cotter [1a] is properly
fitted and locked.

1.5 Installation
When the Rota clamp is fitted to the assembly as described in the
previous section, the assembled unit is now ready to install.
Proceed as follows:
1. First release the handwheel [2] of the clamping lever until it
reaches its end-position.
2. Fold out the clamping lever.
↳When the support clamp is open, the assembly can now be
lifted into its operating position.
3. Close the two halves of the clamp around the bar.
4. Pull back the U-washer [U] of the clamping lever towards the
handwheel [2].
↳No other adjustments should be made until the handwheel
has been tightened.
5. Fold back the clamping lever.
6. Hand-tighten the handwheel [2].

1.6 Operation / adjustments
Positional adjustment (horizontal position)
NOTICE!
Potential risk of damage to material
Only carry out positional and directional adjustments one at a
time. Never try to make more than one adjustment without having
all others firmly locked.
If an adjustment of the position on the bar is necessary, proceed as
follows:
1. Release the handwheel [2] only so far that the grip on the bar
is loosened.
2. While supporting the weight of the assembly, you can now
make the positional adjustment.
↳Make sure you do not damage the tube (notching).
3. Re-tighten the handwheel after any adjustments.
Horizontal alignment
Horizontal adjustments can be made using the rotatable unit of the
clamp, which can be rotated through 360° in both directions.
Proceed as follows:
1. Open the eccentric lever [3] of the clamp.
2. Set the desired horizontal angle.
↳The angle can be read-off on the scale in relation to the
marking (point) on the clamp. Every graduation mark
corresponds to an increment of 10°. The larger marks
indicate an increment of 30°.
3. Close the eccentric lever [3].

1.7 Care and maintenance
Cleaning
Regularly clean and lubricate the Rota clamp with WD-40® or a
similar product.
Inspections
To eliminate the potential risk of accident because of malfunction
of a component, it is essential to regularly inspect all system
components according to the appropriate regulations for lifting
devices.
▪ Visual inspection of the Rota clamp regarding obvious
deformation and damage (e.g. cracks and corrosion) of the
components including all holes of the components.
▪ Visual inspection of the ring cotter [1a] for obvious damage
and deformation. Also carry out a functional test of the locking
mechanism. If the ring cotter can no longer be properly fitted to
the fixing bolt and locked, it must be exchanged.
▪ Visual inspection of the fixing bolt [1b] regarding deformation
(notching) and damage (e.g. cracks and corrosion).
▪ Visual inspection of the fastening lever and handwheel [2]
regarding deformation and damage (e.g. cracks and corrosion)
and inspection of proper functioning.
▪ Functional inspection of the eccentric lever and the rotatable
unit of the clamp (swivel mechanism for horizontal adjustment)
[3].
▪ The connection between the clamp and the rotatable unit [4] is
adjusted for proper operation by the manufacturer. A visual
inspection of the self-locking nut for correct functioning and an
inspection of the clamp mechanism should be carried out
regularly. If the Rota clamp is damaged or does not work
properly (e.g. twisted clamps or rough-running mechanism of
the clamp), it should only be repaired by d&b.
▪ Open the clamp mechanism and check the outer clamps [5] for
obvious deformation. If the clamps are damaged or do not
work properly (e.g. twisted clamps or rough-running
mechanism), the Rota clamp should only be repaired by d&b.
Ring cotter
Regularly carry out the following inspections.
▪ Functional test of the locking mechanism as described in
Þ Chapter 1.4 "Assembly" on page 5.
▪ Visual inspection for obvious damage and deformation as
shown in the graphic opposite.
If a ring cotter can no longer be properly fitted and locked, it must
be exchanged.
Condition of the ring cotter
[a]: Ring cotter OK. [b]: Exchange the ring cotter.

Adjusting the lever
To ensure proper clamping and even gap dimensions [S] to both
sides of the clamping halves of the rotatable unit [4] while the
lever [3] is in its hinged position (90°), the clamping screw [3a]
needs to be regularly adjusted as follows:
Tools required:
▪ Allen hex key 4 mm
1. Open the lever [3].
2. Adjust the clamping screw [3a] so that the screw only just
begins to tighten.
3. Completely close the lever [3] (90°).
↳Even and proper clamping of the two clamping halves must
be achieved.
If necessary, gradually readjust the clamping screw by a
further ½ turn.
4. Recheck the gap dimensions [S] on both sides.
↳On the lever side, the two clamping halves must not be
blocked.
