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
regularly inspection according to the appropriate
regulations for lifting device of all system components is essential.
Test recommendations
1. 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.
2. Visual inspection of the fixing bolt [1b] regarding deformation
(notching) and damage (e.g. cracks and corrosion).
3. Visual inspection of the fasting lever and hand wheel [2] regarding
deformation and damage (e.g. cracks and corrosion) and inspection
of proper function.
4. Functional inspection of the excentric lever and rotation device
(swivel mechanism for horizontal adjustment) of the clamp [3].
5. The connection between the clamp and the rotation device [4] is
adjusted for proper function by the manufacturer. A visual inspection
of the self-locking nut for correct function and an inspection of the
clamp mechanism should be carried out regularly. In the case of
damage or no proper function (e.g. twisted clamps or rough running
mechanism of the clamp) the Rota Clamp should only be repaired by
d&b audiotechnik.
6. Open the clamp mechanism and check the outer clamps for obvious
deformation - Fig. 14. In the case of damage or no proper function
(e.g. twisted clamps or rough running mechanism of the clamp) the
Rota Clamp should only be repaired by d&b audiotechnik.
7. Visual inspection of the Rue ring cotter [1a] for obvious damage and
deformation. Also carry out a functional test of the locking
mechanism. If the ring cotter can no more be properly fitted to the
fixing bolt and locked it must be exchanged - Fig. 15.
9. Disposal/Environmental protection
The product must be disposed in accordance to the national
environmental regulations.
