Beschreibung
Zusammenfassung:	The invention relates to a chain for sawing through an object, in particular an object located in or on the water, such as a ship, drilling platform, bridge, pipeline, etc. The chain is a link chain. The links are provided with a machining surface coating. Said machining surface coating can comprise grit grains, in particular hard metal grit grains. The grit grains can have a size in the range from 4 to 10 mm and can be applied to the links by hard soldering. In particular, each link can consist of two U-shaped end parts with, between them, a body having a peripheral surface with the machine surface coating running in the longitudinal direction of the link concerned. The invention further relates to a sawing installation for sawing through an object located in or on the water, in which installation amongst other things a chain according to the invention is used. L'invention concerne une scie à chaîne pour scier un objet, en particulier dans l'eau ou à la surface de l'eau, du type bateau, plate-forme de forage, pont, pipeline, etc. Il s'agit d'une chaîne à maillons comportant un revêtement de surface d'usinage, qui peut renfermer des grains de sablage, en particulier des grains de sablage au métal dur. Ces grains peuvent avoir une taille comprise entre 4 et 10 mm et on peut les appliquer aux maillons par brasure forte. En particulier, chaque maillon peut comprendre deux extrémités en U et, entre elles, un corps à surface périphérique sachant que le revêtement de surface se déplace dans la direction longitudinale du maillon concerné. L'invention concerne en outre une installation de sciage pour scier un objet situé dans l'eau ou sur l'eau, cette installation faisant appel notamment à une chaîne conformément à la description susmentionnée.
