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:

Safety Instructions

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.

Maximum Load

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)).

Mounting and Use Instructions

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

Insert the load adapter into the identified flying-frame bores.
Fold back the linchpin and pull it out of the load bolt.
Pull the load bolt out of the load fork.
Place the rotation clamp with the load fork onto the mounted load adapter.
Fasten the load adapter by sliding the load bolt through the load fork and the load adapter.
Secure the load bolt by folding back the linchpin lock washer, inserting the linchpin into the loadbolt bore from above, and folding the lock washer back into position.
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.
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.
Rotate the array as necessary.
For precise orientation down to the degree, refer to the angle scale on the load fork.
Fasten the clamping lever fingertight.
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.

Application Examples

To prevent overloading the accessory, be sure to follow the maximum-load specifications (450 kg including the flying frame and cabling).
Note that the suspension point 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. When in doubt, request a confirmation by local authorities.

Care and Maintenance

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 youuse 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.
Clean this speaker accessory regularly using a corrosion-prevention penetrating oil (for example, WD-40).
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.

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.
