The Erie shops are now Alstom's main North American assembly and manufacturing site for the production of AC traction motors, railway cars, and passenger locomotives.

The mangonel was loaded by lowering a rope with a hook at its end ; this hook was tied to another rope connected to a " pulling " system ( this could be a pulley compound, a gear compound, or even an animal traction system ) to pull the rope and lower the main rod.

Main contractor was Fiat Ferroviaria later acquired by Alstom with two main subcontractors Adtranz and Siemens that was responsible for the traction and train control.

The motor fields are connected across the main traction generator ( MG ) and the motor armatures are connected across the load.

The greatest change to the station during the 1920s and 1930s was the introduction of third rail electrification for all suburban and many main line services, replacing the original LB & SCR overhead scheme by 1929 and largely replacing steam traction, except on Chatham Section mainline trains.

Both Victorian Railways and New South Wales Government Railways, which pioneered electric traction in Australia in the early 20th century and continue to operate 1, 500 V DC Electric Multiple Unit services, have withdrawn their fleets of main line electric locomotives.

*: preceding main line Isesaki Line applied steam traction, but a long branch to Nikk &# 333 ; was built electrified, more than 100 km from terminus Asakusa in Tokyo on the main line.

The 2-10-0's main advantage was that five out of six of its axles were powered, meaning almost all the weight was available for traction rather than being distributed over pilot and trailing wheels.

The main drawback of part-time all-wheel drive is that because it lacks a center differential, the system can only be used in low traction situations where the wheels have the ability to slip as needed.

During braking, the motor fields are connected across either the main traction generator ( diesel-electric loco ) or the supply ( electric locomotive ) and the motor armatures are connected across either the brake grids or supply line.

With the locomotive stationary, the main generator ( MG ) output is connected to the grids instead of the traction motors.

Whilst almost all other diesel locomotives were diesel-electric, the Western Region employed a policy of using diesel-hydraulic traction, originally commissioning three classes of main line locomotives — a type 2 and two type 4s ( later designations class 22, class 41 and class 42 ).

* Concise history of the traction engine – evolution, from earliest experiments to widespread manufacture, plus definitions of the six main types

The key difference between the two vehicles is that on a roller the main roll replaces the front wheels and axle that would be fitted to a traction engine.

The main applications are in variable frequency inverters, drives and traction.

Both vehicles faced number of tests in Malaysia SP1 was used for traction tests and has made 7000 km offroad in Malaysia, SP2 2000 km and 500 shoots from main cannon.

Services operating north of Birmingham on the West Coast main line switched to electric traction using class 86 and class 90 locomotives.

The main Rail Control Centre ( RCC ) directs the rail traffic and operates the signalling, traction, pumping, lighting and ventilation.

It was demolished by a traction engine in 1925, with some of the main beams being sold to an American millionaire, Mr Brady.

During the planning of the Hardanger Line and the Flåm Line during the 30s the suggestion again arose, and both the branch lines were built with electric traction, but not the main line.

More precisely, while traction and pulsion mechanisms have long been deemed the main factors promoting development of a Zenker's diverticulum, current consensus considers occlusive mechanisms to be most important: uncoordinated swallowing, impaired relaxation and spasm of the cricopharyngeus muscle lead to an increase in pressure within the distal pharynx, so that its wall herniates through the point of least resistance ( variously known as Killian's triangle, Laimer's triangle, and the Killian-Laimer triangle ).

Latterly, BREL often acted as a sub contractor to a main contractor such as GEC, who supplied the traction equipment.

One of the main aspects of off-roading is to be able to keep traction on different obstacles.

APUs fitted to extended-range twin-engine operations ( ETOPS ) aircraft are a critical safety device, as they supply backup electricity and compressed air in place of the dead engine or failed main engine generator.

The gearbox transfers power from the main shaft of the engine to an oil-cooled generator for electrical power.

The APU generator engine is a fraction of the main engine's size and uses a fraction of the fuel ; some models can run for eight hours on one US gallon (≈ 4 litres ) of diesel.

The generator also powers the main engine's block and fuel system heaters, so the main engine can be started easily right before departure if the APU is allowed to run for a period beforehand.

The Namco Museum video game music soundtracks use the TR-808 extensively as the main rhythm generator.

The main problem was that the system required a fairly large electrical generator in order to drive the gun, increasing the logistics load in supplying the generators with fuel.

The events of 2006 had a severe impact on the city ’ s main generator of revenue: tourism.

Passenger cars can take the electricity supply for heating and lighting equipment from two main sources: either directly from a head end power generator on the locomotive via bus cables, or by an axle powered generator which continuously charges batteries whenever the train is in motion.

Saturated steam at 600 psi is channeled from each steam generator to a common header, where the steam is then sent to the main engine, electrical generators, aircraft catapult system, and various auxiliaries.

An Auxiliary Power Unit is an on-board generator used in aircraft to start the main engines, usually with compressed air, and to provide electrical power while the aircraft is on the ground.

The main parts of an X-ray Baggage Inspection System are the generator used to generate x-rays, the detector to detect radiation after passing through the baggage, signal processor unit ( usually a PC ) to process the incoming signal from the detector, and a conveyor system for moving baggage into the system.

Three main types of electric vehicles exist, those that are directly powered from an external power station, those that are powered by stored electricity originally from an external power source, and those that are powered by an on-board electrical generator, such as an internal combustion engine ( a hybrid electric vehicle ) or a hydrogen fuel cell.

The PSS consists of four main components: a ramcombustor with integrated nozzleless booster ; the air intakes ; the interstage ; and the sustain gas generator.

* gas generator cycle – a small percentage of the propellants are burnt in a preburner to power a turbopump and then exhausted through a separate nozzle, or low down on the main one.

The main infrastructure achievements over the 180 years that connected Boorowa to the rest of the Colony included the first Post Office and mail service in 1835, the electric telegraph in 1866, voice telephone in 1906, electric street lighting in the 1920s by the towns own generator, later the town and consumers were connected to the Burrinjuck Hydro electricity system in 1938.

The main order entry system was written in a 4GL code generator called the Logic and Information Network Compiler ( LINC )— since renamed Agile Business Suite by Unisys.

The main generator is an EE 801.

The main generator is an English Electric EE801, 441 A at 430 V.

The main generator is an EE type EE801 / 7D, flange-mounted single bearing rated at 490 kW.

Ross oversaw the construction, the drilling with a specialty rig of two wells and the installation of a solar and generator power system for the main house which enjoys all the comforts of a modern home including full kitchen.
