LOAD GRIPPER WHICH SUSPENSION CENTRE IS ADJUSTABLE TO POSITION OF LOAD CENTRE OF MASS Russian patent published in 2009 - IPC B66C1/10 

FIELD: construction.

SUBSTANCE: load gripper consists of the following component parts: longitudinal bar; sliding member (equipped with a rigging element) which attachment to the longitudinal bar enables the member's lengthwise sliding and position lock; lifting attachments connected to the longitudinal bar and intended for the load pickup. The sliding member consists of a housing with jaws oriented crosswise to the longitudinal bar; the jaws have coaxial through-holes arranged in a circumferential direction that enable insertion of a repositionable shaft. The rigging element is executed in the shape of a link that forms a rotating pair together with the first rocker arm mounted between the sliding member housing jaws so that to enable rotation round a repositionable shaft inserted in the coaxial through-holes of the sliding member housing jaws. The link and the rocker arm rotation axis intersect at right angle. In addition the device is equipped with a second rocker arm installed mounted between the sliding member housing jaws so that to enable rotation around the axis passing through the centre of the circle above-mentioned as well as its position lock with the help of a repositionable shaft. The first and the second rocker ar are interconnected with the help of a cylinder-shaped pivot that has a through-hole enabling insertion of a repositionable shaft when the latter is fitted into the coaxial through-holes of the sliding member housing jaws.

EFFECT: design simplification; reliability and operational safety enhancement; functional improvement.
