BELTS, CABLES, OR ROPES, PREDOMINANTLY USED FOR DRIVING PURPOSES; CHAINS; FITTINGS PREDOMINANTLY USED THEREFOR
Definition statement
This subclass/group covers:

Belts, e.g. V-belts, cables, ropes or chains that are specially adapted for transferring power/force from an input point to an output point to move or drive at least one mechanical part.

The belts, cables, ropes or chains being either

formed into a loop that is intended to travel around an endless path and engage two or more pulleys, sprockets or similar rotating elements and transfer power/force while travelling along its path; or

an elongated element that is intended to travel backward or forward along a path to transfer power/force between one point along its length to another point along its length, e.g. from a drum to a load.

Chains, e.g. hauling- or hoisting-chains, that are not specially adapted for transferring power/force.

Fittings and attachments primarily intended to be connected to or used with the above types of belts, cables, ropes or chains. These include:

means for fastening ends of belts together to form closed loops, e.g. fastenings for conveyor belts or V-belts;

means for fastening cables or ropes to one another or to other objects;

caps or sleeves for fixing on cables or ropes;

means for coupling chains;

components of chains, e.g. shackles, swivels, chain joints, chain links or chain bushes;

hooks as integral parts of chains.
