Use Instructions:
The use instructions in this manual are meant to supplement the operation
recommendations of ASME standard B30.20.
Only trained, designated persons should use the beam tongs. “Designated person” means someone
selected by his or her employer, or by a representative of the employer, as competent to use the beam
tongs. Trainees under the direct supervision of a designated person may use the device. Maintenance
persons and personnel who perform equipment tests also may use the beam tongs when necessary for
the performance of their employment duties.
Step 1: Perform a proper, “Every Lift” inspection as described in the most recent revision of ASME
B30.20, BEFORE you connect the tongs to a hoisting device. Proceed to the next step ONLY IF the
tongs pass the inspection and are deemed safe to use by designated inspection personnel.
Step 2: Connect the tongs to the hoisting device. The tongs must only be connected to the hoist via a
safety hook to prevent accidental detachment from the hoist.

Step 3: Position the tongs above the load as shown in photos 1 and 2. The load must balance when
lifted. As a first approximation of the balance point, move the tongs to a position above the center of the
beam. The center is identified by a dashed line.
DO NOT push or pull the tongs so that the hoist chain/rope is not vertical. All horizontal
adjustments to the position of the tongs must be accomplished by moving the trolley. This is important
because any deflection of the chain/rope from straight up-and-down will cause the load to swing when
lifted. A swinging load may cause serious personal injuries.

Step 4: Engage the beam with the tongs. Open the tongs by pulling the clamping arms in opposite
directions as shown in photos 3-5. The angled teeth (circled in photo 3) allow the clamping arms to engage
the top portion of an I-beam. Adjust the position of the tongs to allow BOTH teeth to make solid contact
with the beam (photos 5 & 6).
