The invention concerns a swinging suspender with double action brake for suspending a working tool from a crane jib (15). The suspender comprises a body portion (1, 16) having connecting lugs (2, 22) at its opposite ends. A connecting piece (4) is connected to the first connecting lugs (2) with a first pivot pin or bolt (3) which constitutes a first pivot axis which enables swinging of the working tool. A jointing lug (14) of the working tool is connected to the second connecting lugs (22) with a second pivot pin or bolt (11) which constitutes a second pivot axis which enables swinging of the working tool, said first and second pivot axis having their directions perpendicular to each other, thereby enabling swinging of the working tool in two perpendicular directions. For the double action brake there is a hydraulic, pneumatic or electric cylinder (6, 16) between the pivot pins or bolts (3, 11), and one or two pistons (6a, 6b) in the cylinder (6, 16). The opposite ends of the piston (6b) and cylinder (6) or the opposite ends of the two pistons (6a, 6b) are shaped as concave braking surfaces (7, 8). The connecting piece (4) and the jointing lug (14) are provided with convex braking surfaces (5, 10) which are adapted to be pressed into a braking contact with the concave braking surfaces (7, 8) when the piston (6b) or pistons (6a, 6b) are extended from the cylinder (6, 16). The cylinder (6, 16) has a center line which passes through the concave and convex braking surfaces (7, 8; 5, 10) which are in the form of partial circles.
