Roll the dolly into position beneath the suspension frame. Remove the pins
at the front of the frame which secure its captive tongues. Lower the frame
onto the top box, locating the front tongues within the front rigging
assembly. Secure the tongues in position with the quick release pin.
Release the rear splay arms of the top box and attach them to the rear
receivers in the suspension frame using the quick release pins stored at the
rear of the top enclosure.
Safety Note
Use great care when handling quick release pins, front tongues and
rear splay arms.
Never, in any circumstances, insert a finger or hand into the slot in
the rear splay arm. Never insert fingers or hands between boxes when
chain hoists are moving.
Step 3
Slowly raise the suspension frame using the chain motor. As it lifts, the
slots in the splay arms will slide on the quick release pins until they achieve
the pre-set splay angle. At this point, a second quick release pin (supplied
with the dolly) may be inserted in the rear channels to rigidise the array if
required. Note that the second pin is optional and intended to prevent the
rear of the array from collapsing upwards under a high degree of tilt or
when a separate pull-up under-frame is used.
Step 4
Remove the pins securing the bottom box to the dolly and lift the block of
boxes off the dolly.
Safety Check
As the array is lifted off the dolly, make sure that all the quick release
pins are in their correct locations and secure. The pins are locked
when their central buttons are out. Check that the splay angles are the
same on both sides of each enclosure.
Step 5
Wheel the dolly out of the way and then roll another dolly beneath the
array. Pre-rig the splay angles of the lower boxes on the dolly as in Step 2.
