Vestil DLT 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 die tongs. “Designated person” means someone
selected by his or her employer, or by a representative of the employer, as competent to use the die
tongs. Trainees under the direct supervision of a designated person may use the device. Maintenance
persons and personnel who perform tests also may use the die 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 1-3. 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 die
(side views shown in photos 1 & 2). The center is identified by a dashed line. Photo 3 shows the same
orientation of tongs and die from a front view.
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.
