Various pad frame configurations enable the lifter to match different load dimensions. The
illustrations on the preceding page show all approved configurations. Dimensions show Pad
Spread for a standard MRT411LDC(3) lifter (see “SPECIFICATIONS” on page 3 for other models).
Caution:
Position the vacuum pads for the 2 circuits of the dual vacuum system (marked “1” and
“2” in the preceding illustrations).
1)
Use only approved pad frame
configurations.
Securely position vacuum hoses to
avoid damage during lifter operation.
Choose an approved configuration to
maximize support across the load
surface and to minimize load overhang
(see
).
2) Install or remove the extension arms
and reposition the movable pad mounts as needed.
