Tandemloc’s off-the-shelf AR12 Diametral Tongs range in capacities up to 3,000 pounds with a 14-inch maximum diameter.
The diameter also can be customized per the customer’s requirements. Units are for handling cylindrical items such as pipe, round bar, and any other cylindrical item falling within the working load limit and diameter size each tong is designed for. The AR12 Series Tongs include the Tandemloc Autolatch for object engagement. Autolatch feature allows the tong to engage and capture the load, perform the lift, and then safely disengage from the load upon the placement in its new location—all without electrical or manual human involvement. As with all the company’s below-the-hook lifting devices, these tongs are proof tested and certified to 125 percent of the working load limit and meet ASME B30.20 and BTH-1 specifications.
