Repeat Steps 3-6
Safety Check
As the array is lifted, make a visual and physical check to 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.
3.2b Multiple Enclosures on a Dolly
With this method, the boxes are transported on a 3 or 4 box dolly, with the
sliding front tongues between each cabinet already connected.
Step 1
Attach the chain motors to the suspension frame and raise the frame to a
height sufficient to clear the dolly.
Caution should be exercised by personnel near the unloaded frame as
it will tilt to one side because its own centre of gravity is not on the
same line as the pick-up points.
Step 2
Pre-rig the splay angles of the lower enclosures off-load by releasing the
rear splay arm and swinging it up into the rear channel of the enclosure
above. Remove a quick release pin from its storage position at the rear of
the enclosure and insert it through the appropriate marked channel hole
and through the slot in the splay arm.
Note that a pin is locked when its central button is out.
