Cross Frame Installation
1. When the concrete has cured, you can mount the
cross frame to the slab.
2. The area around the slab must be cleared and lev-
el before the cross frame can be lifted into position.
3. Pick the cross frame using the proper lifting points.
4. Place the cross frame into position on the slab.
5. Check with levelling instrument to ensure that the
frame is level. Use steel shims or packers to level
the cross frame.
6. Once the cross frame is centered and levelled the
lifting gear is removed.
7. Secure the frame in place using 4 each 1-3/4”
plates (supplied with cross frame) and with 8 each
1-1/2” double nuts and washers.
