A method is described for coupling and uncoupling of a load (110/110a) to/from a hoisting line, in the form of a tool (100) that comprises a hook housing (104) and a lifting hook (108) and where the lifting hook (108) is pivot connected to an axis of rotation (107) for the hook housing (104) and the hook housing (104) comprises an accumulator the energy from which is used to pivot the lifting hook (108) back from the load-bearing position to an upper position where the load us uncoupled. The method is characterised in that the hook is held with the help of a locking body so that it cannot pivot in its lower, load-bearing position as long as an angle a° of the tool in relation to the reference angle X-X is smaller than an adjustable, set locking angle ß° in relation to X-X and when a° exceeds the locking angle ß° a sequence of pivoting is initiated which either starts pivot of the hook to the upper position immediately, or which holds the hook locked a given time before said pivoting starts. Also described is a tool to execute the method. Furthermore, a device is described for the mounting of a hook to a hook housing. |
