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 Step 5. Do not progress to step 6 until the sheet balances.

Raised a few inches
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. Walk
slowly and move the load to the work location.
a) Regularly review and apply all
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.
