The SCPA clamp is capable of handling steel plate from horizontal to vertical to horizontal through a 180 degree arc and may be used for handling plate at rolling and forming machines. Each clamp is given a RFID transponder as standard, for simplified inspection and documentation. These clamps feature a spring loaded pivoting cam jaw that “cams in” when a load is applied to the lifting shackle. Clamp is capable of handling plate horizontally when used in pairs or sets of pairs, or in a tripod arrangement. Pivoting shackle assembly, as shown, is available on capacities 3 tons and larger.
