A crane grab head (100) comprising a pair of jaws (102;104), a power source for moving the jaws, and a connector (116) for connecting the grab head (100) to a crane, wherein each jaw (102;104) comprises at least one tooth (110) for engaging with an object. Each jaw (102;104) is driven by a respective hydraulic/pneumatic cylinder (108a;108b) which is slideable linearly to move the jaws (102;104) between open and closed positions. The width of the grab measured between the extremities of the jaws (102;104) in the closed position is more than 1500mm. The separation between a horizontal plane passing through the top of the uppermost cylinder (108a;108b) when the head (100) is held freely in normal use and a parallel plane passing through the lowermost edge of the lowermost tooth (110) is less than 250mm.
