STEP 5: Confirm that the sheet balances when suspended. Raise the load a few inches above the ground or other
supporting surface (see photo 5). The material is balanced if the top edge is substantially level. It is not level is one
side is lower than the other side). If improperly balanced, return the sheet to the ground or other supporting surface
and immobilize it. Reposition the clamp to improve balance by moving the clamp slightly towards the end that
hung lower during the test; then raise the object again to see if it is balanced. DO NOT proceed to the next step
until the load is properly balanced. DO NOT use the clamp if you cannot achieve a balanced hold; use a different
lifting device to raise and move the sheet.
Use more than 1 clamp if the load cannot be balanced with a single plate clamp (long or flexible load).
For instance, connect a chain sling to the hoist hook and attach a plate clamp to each end of the sling via
safety hooks. This setup is demonstrated in the below diagram. Test the balance of the sheet material
again by repeating the process of this Step (5). Do not continue to step 6 until the sheet balances.
STEP 6: Lift the sheet to an ergonomically comfortable height. Steady the load by grasping the hoist hook or the
bale of the clamp. Do not apply any weight to the top edge of the sheet material. Do not touch the lock lever.
Avoid contact with the lock ring. Walk slowly and move the load to the work location.
LIFTING RULES
a) Regularly review and apply all SAFETY INSTRUCTIONS from p. 2-3, as well as the Operation section of the
applicable chapter of ASME B30.20.
b) NEVER lift material over yourself or other persons. Inform people in the work area that you are going to use the
clamp. Make sure that all persons have cleared the area before lifting and moving material.
c) Stabilize suspended material by grasping the hoist hook or clamp bale while raising, lowering, or moving the
material.
d) Always stand at arm’s length to the side of the material. If two or more clamps are used, grasp the clamp (bale)
that provides you with the most control of the sheet material. The below diagram labeled “Properly grasp the
second clamp” illustrates the situation where grasping the trailing clamp provides the best control. If you cannot
adequately control the sheet by yourself, ask someone to help you. The second person should grasp another
clamp (bale). Make sure that your clothing, feet, and the rest of your body stay out from underneath the load. This
stance allows the operator to exercise some control of the load and optimizes safety.
e) The sheet must remain substantially level while it is moved. Walk slowly. Keep the load level.
• If your hoist is moved by a motorized trolley, allow the trolley to provide all movement. DO NOT push or pull
the clamp or the load.
• If you use a manual trolley, grasp the clamp with one hand and carefully move the trolley. DO NOT push or
pull the sheet. Walk slowly to keep the load level.
This side of the sheet material
hangs lower than the other.
Return the material to the
ground (or other supporting
surface) and reposition the
clamp by moving it closer to this
end.
