Embodiment Construction

[0030] [30] The hoisting device shown in FIG. 1 has a winch 2 that moves on a guide rail and supports a member 1 held by a sling 3 .

[0031] [31] The winch moves on guide rails according to a control device not shown because it is customary. Likewise, the slings can be shortened or extended by winches in order to position the held member opposite a ground structure on which the held member has to be fitted.

[0032] [32] In fact, the winch can be replaced by any lifting device that utilizes a sling to lift the load.

[0033] [33] According to the invention, the sling 3 is provided with a first inextensible portion 3a, which rests on a section 3c provided with spring elements 10, 10' which, under load, can For a limited variation of the load on the member 1, said spring members 10, 10' allow a limited range of elastic elongation or shortening of said sling 3. The sling according to the shown embodiment is also provided with a second inextensible portion 3b, which is located ...

Abstract

The invention relates to a sling device for a piece (1), comprising a sling (3) provided with a non-extending piece (3a, 3b) and a section (3c) with spring means (10, 10') permitting an elastic lengthening or shortening under load of a limited given amplitude for the sling (3) in response to a limited given change in load on the piece (1).

Description

technical field [0001] [01] The present invention relates to a hoisting device for a component with force compensation, said hoisting device being particularly suitable for use in conjunction with a lifting system, such as a grue or bridge crane carrying hoisting components, the present invention The invention also relates to a lifting system comprising such a lifting device. Background technique [0002] [02] In the positioning of heavy components, such as structural parts of a device to be assembled, overhead cranes, which are suspended from frames in the assembly site, or fixed or mobile lifts, are usually used as lift system. [0003] [03] This type of lifting system is used for handling heavy components, usually in the order of one hundred kilograms to tens of tons, carried by a sling, while the lifting system provides Positioning with high precision, as is often the case when assembling components of buildings, ships, aircraft or other devices such as generators. ...
