Language note You will find the following vocabulary useful in this section. conventional, eliminate (problems), superior (quality), (energy-)efficient, enhanced, reduce completely, significantly, dramatically, entirely, highly, extremely, considerably, totally, exceptionally

Extension activity: more vocabulary The meaning of some of the terms in Exercise 11a in more detail. belt = a drive belt – belts can have a flat or V-shaped section cable = a rope made of metal wires – when used for lifting it is also called a wire rope coated = surrounded by another material – a coating crowned machine sheave = a sheave is a wheel used in association with a belt, often called a pulley; crowned – describes the section of the wheel, meaning it has a ridge at either side to prevent the belt from coming off hoistway = a vertical shaft inside a building which houses a lift (British English – lift shaft)

Extension activity: more vocabulary You could look at the meaning of some of the terms in Exercise 11c in more detail. gearless = has no gears – gears are cogwheels which mesh together to transfer drive from one wheel to another wear = progressive degradation due to normal use, for example vehicle tyres cords = wires machine room = a room in a building where machines, such as lift machinery, air conditioning units and water pumps are located – also often called a plant room, plant being an alternative collective term for machines

Extension activity: brand superiority which brands have a reputation for technical superiority / high quality in the following areas. electrical kitchen appliances (refrigerators, ovens, dishwashers, etc.) Computers Mobile phones Is the higher cost of some brands justified in terms of quality and durability? Do any other brands offer better value for money, in terms of quality / technical superiority versus cost?

The key to Otis’s patented drive technology At the heart of the Gen2TM elevator system is a flat belt (developed by unique to Otis). It is just 3 mm thick. Yet is stronger than conventional steel cables. It lasts up to three times longer. And it has enabled Otis to completely re-invent the elevator The flat, coated-steel belt totally eliminates the metal-to-metal effect of conventional systems. Coupled with a smooth-surface crowned machine sheave, the result is exceptionally quiet operation and superior ride comfort. Furthermore, the flexible flat belt enables a more compact, energy-efficient machine, which can be contained in the hoistway. This enhanced technology reduces building and system operating costs, and frees up valuable space.

Protecting the environment Neither the belt nor the gearless machine, with its permanently sealed bearings, requires any lubrication so the Gen2TM system is cleaner for the environment. The highly (1) energy-efficient gearless machine with its permanent- magnet synchronous motor, (2)_________power consumption by as much as 50% over (3) _________ geared machines and 15% over other machines with permanent-magnet motors of axial construction.

Reliable by design Long lasting flat belts, smooth, crowned sheaves and minimal moving parts in the gearless machine dramatically (4) ____ wear and increase durability and efficiency. To further (5) _______ reliability and safety, Otis developed the Pulse TM system, which continually monitors the status of the belts’ steel cords. Unlike visual inspections of (6) _______ steel ropes, the Pulse TM system automatically detects and reports belt faults to maintenance personnel for rapid response, providing owners with greater peace of mind. With flat belt technology, Otis has created (7) ________ system that (8) _______ the need for a machine room, is quiet, clean, reliable and economical, and easy to install and maintain.

Complete the following sentences from the briefing by underlining the correct emphasizsing word. 1. We've come up with a completely/significantly unique profile. 2. It completely/dramatically reduces vibration. 3. Machines like these can never be entirely/highly free from vibration. 4. The new design runs dramatically/extremely smoothly. 5. Another advantage of the new profile is that it's considerably/entirely lighter. 6. So compared with our previous range, it's highly/totally efficient. 7. Trials so far suggest the design is completely/exceptionally durable. 8. We expect it to be entirely/significantly more reliable than rival units.
