LM-series fork-mountable booms 01/11
Test the stability of the load attachment. Raise the forks slowly to minimize load movement. Raise the forks until the
load is entirely suspended from the boom. Watch the load and boom closely for either of the following issues:
1. Load sliding in rigging; or
2. Boom sliding towards tips of forks.
If you notice either #1 or #2 occurring, immediately lower the forks until the load is completely supported by the
ground; then adjust the rigging. Retest the stability of the load in the rigging. If a stable lift cannot be performed, DO
NOT use the boom.
While transporting a load with the boom, the load should only be 6-8 inches from the ground, but adjusted to avoid
obstacles along the travel path.
DO NOT exceed approximately 1.5mi./hr (2.4km/hr) while transporting a load with the boom, and travel ONLY on
smooth, level surfaces. Execute turns slowly and smoothly.
a. Connect the load to appropriate rigging;
b. Attach the rigging to the end hook or to both the end hook and the stabilizing hook;

c.
Verify that the load attachment is stable (see “Test the stability of the load attachment” in the warning
messages above);
d. Raise the load until it is elevated no more than 6-8 inches above the ground (entirely suspended from
the boom).
e. Slowly transport the load to the desired unloading location;
f. Slowly lower the load until it is entirely supported by the ground, and there is slack in all rigging.
g. Disconnect the rigging from the hooks;
h. Lower the forks until they are no more than 6-8 inches above the ground;
i. Transport the boom to its storage location.

NOTE: Users of OBT and OBNT model booms should return the boom to the fully
lowered (horizontal) position by reversing Step 4 on p. 23 BEFORE backing out of
the fork pockets.
