Vestil BC series - Manual (Page 7)

Use Instructions:
The operating instructions in this manual are meant to supplement the operation
recommendations of ASME standard B30.20.
Only trained, designated persons should use the beam clamp. “Designated person” means someone
selected by his or her employer, or by a representative of the employer, as competent to use the beam
clamp. Trainees under the direct supervision of a designated person may use the clamp. Maintenance
persons and personnel who perform tests also may use the beam clamp 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 clamp to a hoisting device. Proceed to the next step ONLY IF the
clamp passes the inspection and is deemed safe to use by designated inspection personnel.
Step 2: Connect the clamp to the hoisting device. Only connect the clamp to the hoist via a safety hook
to prevent accidental detachment from the hoist.

Step 3: Open the clamp by rotating the handle counterclockwise. Move the trolley to position the clamp
above a beam as shown in photo 1. The beam must balance when lifted, and as a first approximation of
the balance point, position the clamp above the center of the beam.
DO NOT push or pull the clamp so that the hoist chain/rope is not vertical. All horizontal
adjustments in the position of the clamp 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.
