Heave balance device () can balance a lifted or supported load (). The load can be lifted by a hoisting device () or it can be supported. The heave balance device comprises a first frame () and a connection unit () that can be suspended, e.g. to a hoisting device. Further a moveable carrying unit () allows for carrying (suspending or supporting) a load. The device comprises a transmission that couples the connection unit and carrying unit, wherein said transmission is arranged to guide the connection unit and the carrying unit to move along a guideline with respect to each other, the transmission having a spring force balancing arrangement () with one or more leverage units, such as one or more pivoting arms (), and with one or more configurable (gas- or) hydropneumatic springs. A method comprises suspending the load via a (heave) balance device. Further a kit of parts for hoisting devices is provided to allow load decoupling.
