Abstract: The present invention relates to a balanced support device, comprising: a wagon configured to move along a wagon rail, a frame connected to the wagon and extending over a vertical distance from the wagon, a rail connected to the frame and a carriage movably arranged on said rail, at least one protruding arm comprising a support member for supporting amass, wherein the protruding arm is pivotably connected to the carriage, wherein the protruding arm comprises multiple segments which are movable relative to one another in order to allow the support member to move toward and away from the frame, wherein the support member is mounted to the protruding arm via a rotary connection, allowing the support member including a mass to be rotated, and a vertical balance system for exerting an upwards force on the carriage for counteracting a weight of the mass, the arm and the carriage, wherein the vertical balance system is constructed and arranged to control said force in order to balance masses of different weights.

Abstract: 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 suppor
