Rolling mills in steel, aluminium, and copper production subject their drive gearboxes to the highest continuous torque density of any metal manufacturing application — the roll separating force on a hot strip mill can reach 20–50 MN between the work rolls,...

The slewing planetary gearbox on a tower crane rotates the entire jib, trolley, and counterweight assembly around the mast — a structure weighing 15–50 tonnes on a large tower crane, swinging through 360° of arc to position loads anywhere within the crane’s...

The hoist planetary gearbox on a crane is the component that, when it fails, results in a load drop — one of the most dangerous events in any industrial setting. The engineering requirements for a crane hoist planetary gearbox therefore start not with a torque...

The drive axle planetary reducer on a wheel loader is the final mechanical stage that converts transmission torque into the tractive force that pushes the machine into a pile, carries the bucket to the dump point, and backs the machine away for the next pass. Wheel...

Mining drill rigs — rotary blast hole drills, surface top-hammer rigs, and rotary core drilling machines — rely on planetary gearboxes at the rotary head, the feed system, and the carousel indexer. The head drive must deliver high torque at low rotational speed during...
