Abstract
A slinging device for a piece includes a sling with a nonextensible part and a section with a spring device, enabling an elastic lengthening or shortening of the sling under load by a limited amplitude in response to a limited change in the load on the piece, the device including a frame and a floating support, the spring device holding the floating support in the absence of application of force to the piece along a vertical axis, in a position of equilibrium centered vertically with respect to the frame under the weight of the piece, and a way for regulating and adapting the position of equilibrium of the floating support depending on the weight of the piece.
