User's Manual K&F Rotation Clamp 450

2. Product Description

The K&F rotation clamp creates a robust and safe connection between the load adapter of a

suitable K&F flying frame and a standard truss or similar pipe system. It allows you to freely

rotate the suspended speakers and to lock them in the desired position using a clamping

lever.

Note that the half couplers of the K&F rotation clamp 450 are not interchangeable. Structures

made of trusses or pipes with a diameter of 48–51 or 60 mm, respectively, can be used.

In compliance with the German DGUV regulation 17 (BGV C1), the K&F rotation clamp is

capable of carrying a total load of 450 kg (speaker including flying frame and all further

loads such as cabling, load adapters, etc.).

The K&F rotation clamp can be used with the following products:

• not_found

• K&F VIDA L flying frame

• K&F SEQUNEZA 5 flying frame

• K&F SEQUENZA 10 flying frame

2.1 Intended Use

2.4 ID plates and safety labels

Tip

You can tell the 50-mm and 60-mm rotation-clamp types apart by their ID plates and the

mounted half couplers: The half-coupler of the 50-mm type is black while the one of the 60-

mm type is silver.

Before you start mounting a rotation clamp, always make sure you are about to use the

rotation-clamp type suitable for the application at hand (i.e. the pipe diameter).

3. Safety Instructions

Warning

Suspended loads pose a safety risk.

Only qualified technicians are permitted to perform the installation steps. Be sure to use

personal protective equipment at all times.

The technicians installing the speaker on site are responsible for and guarantee safe setup

and use.

Never use signal cables or power cords for suspending, aligning, or securing the systems.

Note that the suspension points (i.e. trusses or pipes) must comply with the DGUV regulation

17 (BGV C1) or similar locally applicable accident-control standards. The maximum load must

have been certified by an authorized expert.

Unless otherwise stated, use only KLING & FREITAG original parts for mounting the speakers.

Never use other parts (in particular, parts made by third parties not listed in this manual).

Be sure to always visually inspect all safety-related speaker and accessory components

before use. If there are signs of wear, cracks, or deformation, etc., replace the affected parts

immediately. Visual inspection also includes checking all screwed connections of supporting

components.

The information described here does not relieve the user of the duty to follow the given

safety requirements and legal regulations.

Never make any modifications to the K&F Drehklemme 450 or replace individual

components.

3.1 Maximum Load

Warning

Be sure to load the K&F rotation clamp 450 with the K&F SPECTRA 212 flybar, K&F VIDA L

flying frame, K&F SEQUENZA 5 flying frame or K&F SEQUENZA 10 flying frame!

The maximum load including the flying frame, all speakers, and all connecting cables must

never exceed 450 kg (as required by DGUV regulation 17 (BGV C1)).

User's Manual K&F Rotation Clamp 450

4. Mounting and Use Instructions

Tip

With early SEQUENZA 5 load adapters, the load bolt may not smoothly slide into the load-

adapter hole. This is due to the load-adapter coating.

In this case, drive the load bolt carefully through the adapter by applying gentle blows to the

bolt using a plastic hammer.

Next, pull the two components apart again and attach the flying frame to the rotation clamp

as detailed below.

The following illustrations show an exemplary assembly of the K&F Rotation Clamp 450.

1) Insert the load adapter into the

identified flying-frame bores.

2) Fold back the linchpin and pull it

out of the load bolt.

User's Manual K&F Rotation Clamp 450

3) Pull the load bolt out of the load

fork.

4) Place the rotation clamp with the

load fork onto the mounted load

adapter.

User's Manual K&F Rotation Clamp 450

5) Fasten the load adapter by sliding

the load bolt through the load fork

and the load adapter.

6) Secure the load bolt by folding

back the linchpin lock washer,

inserting the linchpin into the load-

bolt bore from above, and folding

the lock washer back into position.

User's Manual K&F Rotation Clamp 450

Warning

Danger! Risk of injury from

falling objects!

Improperly assembled speaker

suspension kits s are not safe

for speaker installation. Objects

falling down impose a deadly

risk for people standing near-by!

Always check all connecting

components for secure fit.

Secure the return spring by folding

back its safety washer.

8) Next, you need to decide whether

to adjust a rotation angle before

suspending the array or first

suspend it and then rotate it.

For threading in the array, release

the clamping lever.

9) Rotate the array as necessary.

For precise orientation down to the

degree, refer to the angle scale on

the load fork.

User's Manual K&F Rotation Clamp 450

10) Fasten the clamping lever finger-

tight.

11) For appearance, you can move the

clamping lever into any direction

without loosening the array-

orientation lock.

For this purpose, pull the lever out

a bit, rotate as desired, and release

it when you are finished.

8. Care and Maintenance

Warning

For the owner and user, it is mandatory to be aware that speaker accessories used to fly

or mount the speakers are fundamentally safety-relevant.

Note that the mains cable is supplied with either a connector appropriate for the place

of delivery (see item number) or with open terminals (on the mains side).

Over time, the accessories may exhibit signs of wear, for example, from mechanical strain,

transport damage, corrosion, or improper handling.

As a basic principle, you must visually inspect the speaker accessory before and after you

use it. For fixed installations, you must inspect it for signs of wear at regular intervals.

When performing those checks, particularly look for deformations, cracks, dents, damage

to threads, and corrosion. Also check slings and lifts (e.g. shackles, chains, and steel

ropes) carefully for wear and deformation.

If as a result of these checks any uncertainty should arise with regard to safety or if

specific faults are found, stop using the accessories and send in the product to KLING &

FREITAG GmbH for inspection and repairs, if necessary.

Inspection regulations may vary depending on application and country of use. Observe

all applicable regulations; when in doubt, contact the local authorities.

Many countries require regular inspection of mounting components and accessories. An

additional annual inspection is typically required to be performed by a technical expert.

Moreover, a legally certified or official authority must perform a detailed inspection

every four years.

Therefore, be sure to maintain an inspection log. Enter the values determined for each

speaker and accessory during the periodic checks into this log. This way, relevant data

are always at hand in case of inspection. The log should also document maintenance

measures and inspection intervals and contain parts lists.

2. Clean this speaker accessory regularly using a corrosion-prevention penetrating oil (for

example, WD-40).

3. The half-coupler fixing screws are high-strength and have undergone special surface

treatment. In the event of loss, replace with Kling & Freitag original screws only.

User's Manual K&F Rotation Clamp 450

9. Transportation and Storage

The K&F Rotation Clamp 450 is protected against the effects of unfavorable temporary

weather conditions, etc.; Despite, be sure to store, transport, and use the accessories in dry

environments only. Speaker accessories are not designed for prolonged use in corrosive

environments.

Make sure that the system is adequately ventilated during longer storage periods so any

residual moisture can escape from the equipment.

10. Disposal

Dispose of this product according to local ordinance regulations.

Ensure that the product cannot be re-used or used otherwise after disposal.
