User manual MARTIN AUDIO AQX SCHEMATICS

[. . . ] Different operating and safety requirements between and within countries make it impossible to give universally definitive advice on safety, so it is important that users consult with local regulatory authorities for specific guidelines. This manual is not the definitive guide to safe working practice in the use of flying systems but is advisory in nature and intended to promote safety by providing clear information on the capabilities, adjustment and safe use of the AQX flying system. Despite all the care taken in the design and manufacture of the flying system, Martin Audio Ltd. cannot guarantee complete safety whenever a flying system is used. [. . . ] Note that a pin is locked when its central button is out. 8 Martin Audio ­ AQX Flying System ENGLISH ONLY ENGLISH CONTENTS < > PRINT APPLICATIONS GUIDE GUIDES Spring out each of the rear splay arms from its transit position and swing it up into the receptor at the rear of the frame. Secure it in the 0° position by inserting the quick release pin stored at the rear of the enclosure into the hole in the arm. Using front and rear motors Step 1a Position the frame upright with its front on the floor. Attach the chain motors to the suspension frame. Step 2a Roll the first box up to the frame. Remove the pins at the front of the frame which secure its captive front tongues and locate the front tongues within the front rigging assembly of the box . Secure the tongues in position with the quick release pin. Note that a pin is locked when its central button is out. Spring out each of the rear splay arms from its transit position and swing it up into the receptor at the rear of the frame. Secure it in the 0° position by inserting the quick release pin stored at the rear of the enclosure into the hole in the arm. Step 3 Gradually lift the frame using the motor(s) so that the lower rear corner of the lifted box is approximately 1m above the floor. Remove its wheelboard 9 Martin Audio ­ AQX Flying System ENGLISH ONLY ENGLISH CONTENTS < Step 4 > PRINT APPLICATIONS GUIDE GUIDES Roll the next box into position on its wheelboard and lower the frame to align rear of the flown box with the box on the ground. Note: When landing the suspended array on the next dolly, great care must be taken with motor control. This is important to ensure that the entire weight of the suspended array is not borne by the lowest cabinet, the dolly itself or transferred through the dolly to the staging ­ none of which may be able to bear the weight of the entire array. Step 7 Repeat Steps 3 to 6. 3. 3 De-rigging and Dismantling the Array. De-rigging and dismantling the array is essentially a reversal of the procedure followed to construct and fly the system and the same precautions and safety measures apply. The safety wires to the roof structure are first of all released. No one should be present in the area beneath the array whilst it is lowered in an even, smooth and controlled fashion. One box at a Time If the lowest boxes in the array are pinned in the tight 7. 5° position, releasing the front tongues will not allow the front to swing down, as the boxes will bind at the rear. The rear splay angles will first need to be reduced by supporting the weight of the box at the rear and re-pinning at a smaller angle. Only when this has been done can the front tongues be released and the front of the box swung down. Multiple Enclosures on a Dolly When landing the suspended array on a dolly, great care must be taken with motor control. This is important to ensure that the entire weight of the suspended array is not borne by the lowest cabinet, the dolly itself or transferred through the dolly to the staging ­ none of which may be able to bear the weight of the entire array. 13 Martin Audio ­ AQX Flying System ENGLISH ONLY ENGLISH CONTENTS < 4 > PRINT APPLICATIONS GUIDE GUIDES SAFETY POINTS & PROCEDURES (1). To ensure safety, the rigging of loudspeaker flying systems in public or working areas should only be undertaken by specialists, contractors, venue or touring crew personnel with established, proven expertise as riggers and who have read this manual. [. . . ] All moving parts should be examined for free movement, looseness, or signs of wear on adjacent or mating surfaces. All quick release pins should move freely and operate correctly, again checking for signs of deformation or undue wear. On releasing the rear splay arm, the arm should disengage and rotate easily and positively lock into place when re set. The sliding tongue at the front of the enclosure should move freely and be examined for signs of deformation or undue wear. [. . . ]
