Embodiment Construction

[0042] Once the objects of the present invention have been outlined, specific non-limiting embodiments will be described below. These embodiments relate to a lifting device adapted to lift a load in a stable manner and without prior knowledge of the center of mass of the load to be lifted. These examples relate to lifting aerospace parts.

[0043] figure 1 An embodiment of a lifting device ( 1 ) according to the invention for lifting a load (not shown in this figure) is shown. The lifting device (1) includes:

[0044] support beams (2),

[0045] two load carrying devices (3, 4) which are slidable along the support beam (2) and adapted to hold a load (not shown in this figure),

[0046] at least one counterweight (5) capable of sliding along the support beam (2),

[0047] at least one sensor device capable of measuring the weight force borne by the load carrying device (3, 4),

[0048] first drive means (25) adapted to slide the load carrying means (3, 4) along the suppor...

Abstract

The invention relates to the field of lifting loads and controlling lifted loads. In particular, the invention provides a lifting device (1) for lifting a load (9), comprising: a support beam (2); able to slide along the support beam (2) and adapted to hold the load (9 ) of two load carrying devices (3, 4); at least one counterweight (5) capable of sliding along the support beam (2); at least one of the sensors; first drive means adapted to slide the load carrying means (3, 4); second drive means adapted to slide the counterweight (5); third drive means adapted to lift the load (9); a hitch point (13) for hooking by a crane; and processing means adapted to receive information generated by the sensor and adapted to operate the first drive means, the second drive means and the third drive means.

Description

technical field [0001] The invention relates to the field of lifting loads and controlling lifted loads. In particular, the present invention describes a load lifting device adapted to lift and manage a load without prior knowledge of the position of the load's center of mass. Background technique [0002] Numerous devices suitable for lifting loads and controlling lifted loads, such as cranes, bridge cranes, overhead cranes or tower cranes, are known in the art. [0003] In the particular field of lifting and handling heavy loads such as aerospace parts, the center of mass of the part is unknown or may even be variable while being lifted or if the position of the part is changed. In these cases, whenever the center of mass is not vertically aligned with the lift point, the part will oscillate during the lift process. These oscillations may damage the crane or the parts to be lifted, or injure operators working in the surrounding area. [0004] US8000835B2 discloses devic...
