Diameter Tongs are specifically designed to lift round or cylindrical loads (pipe, tube, bars, etc.) A leg contoured to suit the load diameter engages below the center-point of the load where not only is the load cradled by the legs, but also securely clamped on the outside diameter.
Each Diameter Tong is designed for a specific size range; it is very important that Powlift engineers understand the maximum and minimum diameters to be handled.
Single Diameter Tongs
Powlift Tongs are well suited for handling round loads such as pipe, billets, tubing, or ingots. Manual, Semi-Automatic, and Automatic operation is available as an option. Our tong designs wrap around and grip round loads to minimize marking and are custom-designed to suit your specific range of diameters and lengths. Single Tongs are well suited for short loads, or when compact size is important.
Duplex Tongs are the right choice when handling multiple round loads or extremely long loads. Automatic operation is the preferred choice for this type of tong, as it allows virtually “hands-free” operation when attaching to and releasing loads. Our tongs are custom-designed to suit your specific range of diameters and lengths. Most common designs suit horizontal handling applications, but vertical handling solutions are also available.
Powlift offers an extensive range of solutions for handling of Aluminum and Steel Ingots. Vertical drop-casting, continuous casting, ingot storage, ingot scalping, and furnace loading are just some of the many applications where we have provided our highest quality lifting equipment. Whether mechanical or Motorized, our unique, custom designs offer an unparalleled level of safety and performance.
Horizontal Ingot Tongs
Horizontal Ingot Tongs from Powlift are rugged, mill-duty lifting devices suited for continuous operations where reliability and up-time are critical. Powlift offers Horizontal Ingot Tongs with a full mechanical design where the unit is held open by a heavy-duty automatic latching mechanism. Horizontal Ingot Tongs with automatic latches are generally used for single ingot handling. Horizontal Ingot Tongs are a great solution if you are unable to bring power to the unit from your crane or if your application includes a small to medium range of ingot widths. Our mechanical tongs can also be configured for high temperature ingot handling (> 1000°F).
For multiple ingot handling, Hoist Operated or Motorized Horizontal Ingot Tongs are available. Hoist operated tongs can use the auxiliary hoist to control the opening and closing of the tong while suspended from the main hoist. Motorized Horizontal Ingot Tongs utilize an electric motor to open and close the tong (self-contained) for selective pick-and-place of either a single or multiple ingots from a stack.
One of the most common operations when lifting an ingot is “down-ending”: the lift starts with the ingot vertical, but then rotated to a horizontal position. Powlift Vertical Ingot Tongs are ideal for use in this application because of their long track record of safety and performance. Powlift has hundreds of down-ending grabs in operation around the world. Each Ingot Tong can be customized to meet your specific application requirements.
Hydraulic locking devices are available to help to keep the tong legs closed on the load in the event that the bottom of the ingot accidentally contacts the floor, for the ultimate in handling safety. The device is entirely self-contained, and only requires that the operator release the lock when the ingot is at rest in the horizontal position, to reset the tong.
Mot Lay down Grab
Powlift Motorized MOT Laydown Grabs are unmatched in safety and performance. Our unique design is proven in Aluminum Casthouses and ESR casting operations around the world. Redundant locking systems ensure that the grip is not compromised when laying down ingots and provides the utmost productivity for stripping vertical casting pits. Powered rotation, load detecting systems, positioning systems, feedback indicators and other features are also available.
