Lifting Clamps

Super Slings Inc. stocks three brands of plate clamps for handling steel, Renfroe Lifting Clamps, Terrier Lifting Clamps and Crosby IP. Plate clamps are a rigging accessory that are normally suspended from a crane hook and attached to steel to facilitate lifting. Because there are a multitude of steel types, shapes, sizes, and weights, there is a wide variety of plate clamps to choose from. You need to determine all of these variables and select the plate lifting clamp that has the right capacity and grip range for the steel your handling. Also, you need to know what orientation the steel is positioned in at the beginning of the lift, and what orientation it needs to end up in at the end of the lift. This is important because some plate clamps lift vertically only, others in a 90 degree range motion, and others that can move plate 180 degrees. Please contact your Super Slings representative for assistance in deciding which product is best suited for your application.
