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.

(Heave) balancing device, hoisting system, method for hoisting and kit of parts for spring balancing a hoisting system

Method and device () for lifting loads (). An arm () that is the load or that supports a load () is pivotably connected to a reference. The load results in a torque. At least a part of the counter-torque to result in a system supporting the load is provided by a gas or hydro-pneumatic spring ().

Apparatus comprising a pivotable arm and a configurable spring

A spring balanced support device having at least one arm, connected to its surroundings via a movable pivot point, forming an arm mechanism to which a mass may be coupled directly or indirectly at a mass coupling point, balanced by at least one spring, at one end directly or indirectly connected to the arm mechanism at a spring connection point, the other end directly or indirectly connected to the surroundings at a spring base point, wherein the spring base point is located substantially on an axis which extends through the movable pivot point and substantially parallel to a direction of a force exerted on the spring balanced support device at the mass coupling point due to the force of gravity on the mass, or wherein the spring base point is located at a distance from said axis along a line which intersects the axis and which extends substantially parallel to a pivot point axis of the movable pivot point, wherein the movable pivot point is movable along the axis in order to adjust the spring balanced support device.
