Step 4: Engage the sheet with the clamp. Press down firmly on the clamp until the top of the sheet material

contacts the back of the clamp mouth (photos 3a and 3b). Lock the clamp by pulling the lock ring and rotating the

lock wheel assembly upwards.

Step 5: Test the balance of the material in the clamp. Grasp the hoist hook to stabilize the lift, and raise the load

a few inches off of the ground or other supporting surface (see photo 6 below). The material is improperly

balanced if it slides or hangs lower on one side. If improperly balanced, return the material 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.

 If a single clamp cannot balance the load, use a combination of two or more clamps. For instance, you

could connect a chain adapter to the hoist hook, and attach a plate clamp to each end of the adapter via

safety hooks. This setup is demonstrated in the “Use of 2 or More Clamps” diagram below. Afterwards,

retest the balance of the material according to the process described in Step 5. Raise the material ONLY

after achieving proper balance.

Step 6: Lift the material. To raise the sheet, steady the clamp and load by grasping the hoist hook.

[Note: The photographs demonstrate the procedure of using a single plate clamp. For combinations of two or

more clamps, grasp the safety hook of the clamp attached to the back end of the sheet. This is depicted in the

diagram on the following page next to photograph 7.]

Lift the load to approximately waist height. Continue to grasp the hook. Walk slowly and move the load to a

position above the desired location. Refer to the “Warning” messages and follow the lifting rules below.

Review all “Safety Guidelines” (p. 5) & always follow these “Lifting Rules” when using the clamp:

1. NEVER lift material over yourself or other people. Inform everyone in the usage area that you are going to

use the clamp and make sure that all persons have cleared the area before lifting and moving material.

2. DO NOT press down on the sheet material. Grasp ONLY the hoist hook while raising, lowering or moving

material to a different location to stabilize the load.

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.
