Inspection and preventive maintenance
Rigging part inspection
About this task
For critical rigging parts, use the Inspection references (p.65) for comparison and specific manipulations.
The term "rigging part" comprises:
• lifting accessories such as clamps and shackles
• rigging accessories such as rigging frames, rigging interfaces, and brackets
• fasteners used for assembling two products together such as ball-locking pins, rigging axes, and safety pins
• rigging elements integrated in the product such as rigging arms and rails
• screens mounted on enclosures and their rigging screws
• transportation accessories
This inspection procedure covers only L-Acoustics products. To inspect other products that are part of the lifting chain,
refer to the manufacturer's instructions.
Prerequisite
Perform the inspection in a well-lit environment.
Procedure
1. Check that the rigging part is present.
2. If applicable, disassemble the rigging part from the enclosure or the rigging accessory.
Check that the tethers are intact and safely secured.
3. Inspect the part from every side.
Compare with the reference illustrations.
Check for:
• corrosion
• wear and cracks
• bends and dents
• holes
• missing safety cues
• missing identification labels
• missing or loose fasteners
Replacing screws
If a screw is loose, remove and replace it.
Always use the new screws provided in the repair kit.
If no new screw is available, add blue threadlocker before reusing the screw.
Do not apply more than the indicated torque.
4. Check the geometry of the part to identify critical deformations.
Place the rigging part on a flat surface or hold a level against it.
5. Check the moving parts.
Make sure that the mechanism engages correctly.
What to do next
If a problem is detected, perform the authorized maintenance operations or contact your L-Acoustics representative.
