Description
F16G covers flexible and rigid mechanical power transmission elements used primarily for driving applications, including belts, cables, ropes, and chains, along with their associated hardware components. This subclass encompasses the design, construction, and materials of these drive systems, as well as pulleys, sprockets, tensioners, and other fittings integral to their operation. It excludes lifting or hoisting equipment designed primarily for load suspension, which fall under F16H and other sections; the focus here is on continuous rotational or linear motion transmission between mechanical components.
