PRODUCT INTRODUCTION Thank you for purchasing Heavy-Duty Die Lifting Tongs (“die tongs” or simply “tongs”) made by Vestil Manufacturing Corporation (“Vestil”). Our die tongs are durable, high-quality products that combine safety features and superior lifting capabilities. Despite ease of use, all personnel must familiarize themselves with the safe operation instructions provided in this manual. We produce 3 types of tongs, the DLT-20, DLT-25, and DLT-30.
SAFETY GUIDELINES Read the entire manual before attaching the tongs to a lifting device or using them for the first time. Refer to the manual for safe use and maintenance procedures (p. 7-11). If questions remain after you finish reading the manual, contact Vestil for answers. DO NOT attempt to resolve any problems with the tongs unless you are certain that they will be safe to use afterwards. NEVER modify the product in any way without the express, written approval of Vestil.

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.
Step 4: Engage the die with the tongs. Lower the tongs around the die (photos 4-6). The angled teeth (circled in photo 4) will follow the surface of the die as the hoist lowers the tongs. Adjust the position of the tongs to allow ALL 4 teeth to make solid contact with the die (photo 7). 4 5 6 7 Step 5: Test the balance of the die in the tongs. Grasp the hoist hook to add stability (see photo 8) and raise the die just a few inches from the ground (or other supporting surface).
4. If the object has to be removed from a container or be lifted over an obstacle, continue to grasp the hoist hook. You MUST use a different device if you will not be able to maintain the safe stance described in Rule 3. If you are using a motorized trolley: • DO NOT push or pull either the tongs or the die. Allow the trolley to supply all movement. Your hold on the hook is a means ONLY for stabilizing the load. If you are using a manual trolley, • Grasp the hoist hook with one hand.
Step 9: Disconnect the die tongs from the hoist. Maintenance and Inspections: A designated person must verify that the device complies with all regulations, codes, and standards that apply to “Under-the-Hook Lifting Devices” in the location where the tongs are used. The person(s) designated to conduct inspections must do so before the tongs are used for the first time, and EACH time the hook is installed for use.
The reader should understand the significant difference between “Adjustments [and] repairs,” and modifications. An adjustment or repair refers to a simple correction that restores the tongs to normal operating condition, such as tightening loose fasteners, or removing debris. A modification is a change that alters the tongs from normal operating condition, like bending the structural members. NEVER modify the tongs without the express, written approval of Vestil.
