Abstract
A self-aligning apparatus for a lifting system includes a structure which includes a first element having a first projecting free end and a second projecting free end which each receive at least one sheave at a point of attachment to the first element, and at least two first points of rotation. The at least one sheave cooperates with at least one wire. The at least two first points of rotation are arranged above the at least one sheave's point of attachment to the first element so that the apparatus self-aligns during use in an uneven loading event.
Claims22
A self-aligning apparatus for a lifting system, the self-aligning apparatus comprising a structure which comprises:
- a first element comprising a first projecting free end and a second projecting free end which are each configured to receive at least one sheave at a point of attachment to the first element, and at least two first points of rotation;
- a second element;
- a first beam comprising a first first beam end portion and a second first beam end portion;
- and
- a second beam comprising a first second beam end portion and a second second beam end portion, the second beam being arranged opposite to and substantially parallel to the first beam,
- wherein,
- the at least one sheave is configured to cooperate with at least one wire,
- the at least two first points of rotation are arranged above the at least one sheave's point of attachment to the first element so that the apparatus self-aligns during use in an uneven loading event, and
- the first beam and the second beam are connected to each other via a first rotatable connection between the second element, the first first beam end portion, and the first second beam end portion, and a second rotatable connection between the first element, the second first beam end portion, and the second second beam end portion.
A self-aligning apparatus for a lifting system comprising a plurality of sheaves comprising at least a first sheave and a second sheave, the self-aligning apparatus comprising a structure which comprises:
- a first element comprising,
- a first projecting free end,
- a second projecting free end, and
- a third projecting free end which is arranged between the first projecting free end and the second projecting free end,
- each of the first projecting free end and the second projection free end being configured to receive at least one sheave of the plurality of sheaves at a point of attachment to the first element, and at least two first points of rotation,
- the third projecting free end being configured to run in a same direction as the first projecting free end and the second projecting free end, and
- the first projecting free end, the second projecting free end, and the third projecting free end each comprising a respective attachment device which is configured to receive at least one sheave of the plurality of sheaves,
- wherein,
- each of the plurality of sheaves is configured to cooperate with at least one wire,
- the first sheave of the plurality of sheaves is held between the first projecting free end and the third projecting free end,
- the second sheave of the plurality of sheaves is held between the second projecting free end and the third projecting free end,
- each of the plurality of sheaves has a same axis of rotation, and
- the at least two first points of rotation are arranged above plurality of sheaves' point of attachment to the first element so that the apparatus self-aligns during use in an uneven loading event.
