Care and maintenance
Ring cotters
▪ Visual inspection for obvious damage and deformation.
▪ Functional test of the locking mechanism as described
in .Þ Chapter 3 "SL-Series rigging components" Þ 3.11 "Ring
cotters" on page 28.
If a ring cotter can no longer be properly fitted to the fixing bolt
and locked, it must be exchanged.
SL-Series flying frames and compression frames
▪ Visual inspection regarding any indication of deformation and
damage (e.g. cracks and corrosion) including all drilled holes of
the component.
▪ Regularly check the rated break point of the KSL Compression
frame for any indication of deformation. Please also refer to
Þ Chapter 3.4.2 "KSL Compression frame - Rated break point"
on page 21.
▪ Visual inspection regarding the attachment and securing of the
shackles.
▪ Regularly check the flatness of the frames. For this purpose
position the frames on a flat surface and visually check the
frames for deformation and/or torsion. For obvious deformation
and/or torsion contact d&b audiotechnik for further advice on
how to proceed.
SL-Series load beams
▪ Visual inspection regarding any indication of deformation and
damage (e.g. cracks and corrosion) including all drilled holes of
the component.
▪ Visual inspection regarding the attachment and securing of the
shackles.
▪ Regularly check the flatness of the beam. For this purpose,
position the beam on a flat surface and visually check the beam
for deformation and/or torsion. For obvious deformation
and/or torsion, contact d&b audiotechnik for further advice on
how to proceed.
Z5707 SL Aiming plate
▪ Visual inspection regarding any indication of deformation and
damage (e.g. cracks and corrosion) including all drilled holes of
the component.
▪ Visual inspection regarding the attachment and securing of the
shackles, coupling shackle and chain.
SL-Series compression set components
Z5705 Safety chain
Z5706 Hoist connector chain
Z5707 SL Aiming plate
Inspection according to the appropriate regulations for lifting
devices (EN 818-6:2000).
▪ Regularly inspect within a 12 months period.
▪ Regularly inspect for cracks within a 36 months period.
Condition of the ring cotter
[a]: Ring cotter OK
[b]: Exchange the ring cotter
