USING AN ADJUSTABLE MODEL SBM LIFTING BEAM
WARNING
The capacity of the hoist, crane, and rigging should equal or exceed the capacity of the spreader
beam. DO NOT exceed the capacity of the beam, crane, rigging, or the hoist, whichever is smallest.
Load the lifter by applying the following steps. Numbers in parentheses () are part numbers from the
EXPLODED VIEWS on pages 7, 8, and 9. NOTE: Adjusting locations of the load bales requires removing
their lock nuts (37039). Any time a lock nut is removed, it should be replaced with a new lock nut.
1. Attach the hoist hook to the beam bale of the spreader beam. Makes sure that the hoist is
centered above the bale, i.e. the hoist chain/rope must be vertical, to minimize beam swing.
2. Move the beam into position above the load item. Center hoist and the beam bale above the
center of gravity of the load item.
3. Attach rigging to the load item.
4. Adjust the positions of the load bales. Rigging should be vertical when attached to the load item
and to the load bales. To change the position of a load bale, remove the hex nut (37039) and flat
washer (33018) from the hex head bolt (13365); then remove the bolt. Move the bale to the
location necessary to make load rigging vertical when the load is suspended. Reinstall the bolt
and secure it with a flat washer and a new nylon lock nut (37039). Generally, the load bales
should be attached to the beam in the same locations on either side of the bale. If the load item
and beam are not level when the test lift is performed (step 7 below), the center of gravity of the
load item is on the low side of the item instead of being directly below the center of the beam
bale. Relocate the load bales and rigging to position the center of gravity of the load directly
below the center of the bale. Generally, if the load hangs lower on the left side, both load bales
should be shifted to the right. If the load hangs lower on the right side, both load bales should be
shifted to the left.
5. Connect the rigging to the load bales of the beam.
6. Perform a test lift. Raise the load just a few inches above the ground. The load and beam should
balance, i.e. be horizontally level. If one end of the load is lower than the other, return the load to
the ground. Reposition load bales and rigging as necessary to balance the load. When
balanced, the spreader beam and load item are horizontal when the load is entirely suspended
above the ground by the beam.
