Vestil CPC - Manual (Page 5)

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 plate clamp. “Designated person” means someone selected by his
or her employer, or by a representative of the employer, as competent to use the plate 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 plate clamp when necessary for the performance of their employment duties.
Step 1: Perform a proper, “Every Lift” inspection as described in the most recent edition 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 a safety hook to prevent accidental
detachment from the hoist.

Step 3: Unlock the clamp by rotating the latch lever downwards (photo 1). Move the trolley to position
the clamp above the sheet material. The sheet must balance when lifted, so position the clamp above the
center of the sheet. The center of the sheet is indicated by a dashed line in photo 2.
DO NOT attempt a horizontal lift; only lift material vertically.
 All horizontal adjustments in the position of the clamp must be accomplished by moving the trolley.
DO NOT push or pull the clamp so that the hoist chain/rope is not vertical. 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.
