Additional safety with A10-LIFT
On each enclosure on which A10-LIFT is secured, secure a DIN580 eye bolt to the dedicated insert to implement
a secondary safety.
Use a shackle and a steel wire rope. Make sure the steel rope is as tensed as possible without bearing the load.
A scalable radial array of A10 Wide/Focus can be created using multiple A10-LIFT.
A10-LIFT quantity and position
Use one A10-LIFT for up to three enclosures in the array.
Do not leave more than two adjacent enclosures unsupported.
Refer to APPENDIX A: Authorized congurations with A10-LIFT
Risk of tilting
When using a single motor or a bridle, make sure the array is symmetrical.
When using a third-party bridle, make sure the angle between the two chains does not exceed 60°.
