PROBLEM TO BE SOLVED: To instantly respond and prevent slipping down when a workpiece set in a horizontal hanging intact clamp is slipped down by a certain amount during lifting transport.SOLUTION: A horizontal hanging intact clamp includes: a stopper cam 24 rotatably provided in a camming pin 23, separately and independently from a presser cam; a slip detection lever 36 having an engagement part 36a, at one end, capable of abutting on a tip upper surface Wa of a workpiece W inserted into an opening, and having the other end rotatably connected with a clamp body 11; a pull spring 34 for biasing the engaging teeth 25 of the stopper cam in the direction of projecting toward an opening; and an operation link 35 for rotating the stopper cam in a predetermined direction when a slip detection lever is rotated in a predetermined direction, to make the engaging teeth project toward the opening by the tension of the pull spring 34. When the engagement part of the slip detection lever is separated from the workpiece tip upper surface, the engaging teeth of the stopper cam project toward the opening and bite into the workpiece tip upper surface, thus preventing the slipping down of the workpiece. |
