WARNING
If an inspection reveals problems, restore the boom to satisfactory condition BEFORE using it again. DO NOT use a
boom that is structurally damaged in any way. Structural damage includes, but is not limited to, cracked welds,
warping or deformation of the back plate, carriage brackets, boom, or boom sleeve.
1. Before each use —Examine the boom for cracks, significant rusting/corrosion, or damaged hooks, shackles,
carriage brackets.
2. Monthly inspection —At least once per month, and before using the boom for the first time, inspect:
Back plate, carriage brackets, carriage latch, and fasteners —The back plate should be square and solid.
Each bracket should be rigidly welded or fastened to the frame. Examine the carriage latch. Confirm that it
latches and unlatches properly. Look for significant wear, damage, or indications of metal fatigue to any
portion of the carriage brackets and fasteners, back plate, or carriage latch.
Boom —Check all welds. The boom should be straight, rigid, and undamaged, i.e. no cracks, punctures,
warps, rust or corrosion, etc. The boom should slide without binding inside the receiver/sleeve.
Hooks and shackles —Examine the end hook & the stabilizing hook. Record a measurement of the throat
opening of each hook. Compare the measurements with those taken during the very first inspection. Replace
a hook if its throat opening is more than 15 percent wider than the original throat opening measurement, or if
the hook is twisted more than 10° from the plane of the unbent hook. Discard damaged hooks. The latch of
the end hook should close automatically. Shackles should be securely attached to the underside of the boom.
Examine all pins that attach shackles to the boom for cracks and warps.
Frame and fork pockets —Fork tubes should be square and solid. Each tube should be rigidly welded to
the frame. Look for excessive wear, damage to, or metal fatigue in, any portion of the fork pockets,
frame, boom or boom receiver.
Power unit —Remove the covers. See ACCESSING THE POWER UNIT on p. 10.
Safety chain —All links of the chain should be intact and of equal dimensions. The chains should be
securely attached to the lap link. The lap link should be solidly welded to the frame. The snap hook at the
end of the chain should close completely and automatically.
Support leg —Inspect the support leg. It should be straight, undamaged (no cracks or deformations),
and securely attached to the underside of the boom.
Labels —The unit should always be labeled as shown in the LABELING DIAGRAM on p. 11. Replace any
label that is damaged, faded, or not easily readable.
3. Annual Lift Test –At least once per year, perform a LOAD TESTS (p. 10) of the boom. Afterwards, conduct a
MONTHLY INSPECTION. Confirm SATISFACTORY CONDITION before returning the boom to service.
MAINTENANCE
Implement a maintenance program to ensure that the boom remains in satisfactory condition. The following
steps should be utilized in conjunction with maintenance procedures applicable to fork truck attachments
provided in the most recent edition of ANSI B56.1.
Step 1: Tag the boom, “Out of Service.”
Step 2: Remove dirt and other matter from all surfaces.
Step 3: Conduct a Monthly inspection. If significant deformities, corrosion, rusting, or excessive wear is found, DO
NOT continue to use the product.
Step 4: Perform all necessary adjustments, replacements and/or repairs. DO NOT modify the boom.
WARNING
DO NOT return the boom to service until all necessary adjustments and repairs are complete! An adjustment is a
simple correction that restores the boom to SATISFACTORY CONDITION, such as tightening loose fasteners or
removing debris from surfaces. Repair means removal of worn parts and installation of replacement parts. NEVER
modify (alter) the boom, e.g. bend a structural member or remove a part or parts.
Step 5: Make a dated record of all repairs, adjustments, and replacements performed.
