Abstract

The lifting chain for handling rocks has an upper eye (8) with three chain branches of the same length depending from it. The lower branches are connected to three further horizontal lengths by further eyes to defining a lifting triangle (A) to be placed around a rock. As the rock is lifted the chain sections slide through the eye and are locked in place.

Description

La présente invention concerne un dispositif pour lever ou déplacer des rochers ou blocs ou autres produits ou ensembles. The present invention relates to a device for lifting or moving rocks or blocks or other products or assemblies.

Peut être utilisé aussi pour l'arrimage. Can also be used for lashing.

Cette élingue composée de trois ou plusieurs brins en chaîne ou en câble ou en textile, permet grâce à son ensemble solidaire d'encercler et de serrer l'objet ou le bloc à soulever ou à déplacer.  This sling composed of three or more strands in chain or cable or in textile, allows thanks to its integral assembly to encircle and tighten the object or the block to be lifted or moved.

Chaque brin et solidaire de l'autre et ainsi de suite. Chaque brin coulisse dans des anneaux ou manilles. Each strand and integral with the other and so on. Each strand slides in rings or shackles.

Plusieurs dimensions de longueurs et de sections peuvent être construites pour être adaptées aux besoins du produit à lever. Several length and section dimensions can be constructed to suit the needs of the product to be lifted.

Montage technique de l'élingue, généralement composé d'un anneau supérieur avec trois brins inférieur de même longueur qui passent dans des anneaux ou manilles pour coulisser et qui vont se fixer à l'opposé sur l'anneau ou la manille de l'autre brin, et ainsi de suite jusqu'à former un ensemble homogène. Des mailles de raccordement fixées à une certaine longueur bloquent la chaine pour former une chaise qui empêche la charge de basculer.Technical assembly of the sling, generally composed of an upper ring with three lower strands of the same length which pass through rings or shackles to slide and which will be fixed opposite to the ring or the shackle of the other strand, and so on until forming a homogeneous whole. Connection meshes fixed at a certain length block the chain to form a chair which prevents the load from tipping.
