摘要

Load and heave balance device (1). The balance device can balance a lifted or supported load (8). The load can be lifted by a hoisting device (10). The heave balance device comprises a first frame (2) and a connection unit (22) that can be suspended, e.g. to a hoisting device. Further a moveable carrying unit (32) 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 guide line 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 (50, 51), and with one or more configurable (gas- or) hydro-pneumatic springs (4). 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.
