This video details the construction of a Nova LFS Articulated bus, from initial welding to final assembly. Workers utilize specialized jigs and tools for precise stainless steel framework construction and interior fitting. The process showcases various components and materials, including the durable composite flooring and powerful engine. Peter Burgess COMMENTARY Peter Burgess Transcript 0:05 articulated buses are mostly used on public transit routes they consist of two rigid sections linked by a pivoting joint they're longer than rigid bodied buses so they can carry more passengers and thanks to a flexible accordion shaped Central section they can maneuver on busy city streets to build the internal structure of the bus welders Assemble stainless steel tubes during welding these tubes are supported by an orange frame called an assembly jig once they've assembled the roof and the sidewall structures they bring them together on a larger assembly jig the whole structure of the bus is made of stainless steel because it doesn't rust using stainless steel prevents expensive and timeconsuming repairs due to corrosion 1:00 The Jig can rotate like a giant rotisserie giving workers easy access to every part of the bus they need to weld they install metal plates to reinforce the junction between the roof and the sides of the [Music] bus once all the welding is done they'll turn the bus right side up again to install the floors workers apply high strength glue to the floor structure it provides permanent bonding but stays flexible when dry so it will never crack next they carefully lay down a floor panel using a Pneumatic manipulator it's equipped with suction cups to allow easy handling without risk of damaging the floor covering the floor panels are made of composite materials which are durable lightweight and resistant a plastic sheet keeps the floor protected during upcoming steps of the assembly process [Music] 2:00 this is what the back section of the bus looks like once the floor is installed next they'll turn the bus upside down for access to the ceiling they install electrical wiring and copper pipes for the heating system they also install compressed air tanks that will action the brakes as well as the opening and closing of the doors when they finish working on the back section of the bus they'll attach it to the front section using this articulated joint [Music] the bus has been turned right side up again some ceiling panels are now in place as well as the back seats of the bus but there's still a lot of work to do an assembler installs interior panels made of [Music] aluminum he also connects Carper piping for the heating [Music] system using a blowtorch he Heats heats 3:00 up the copper pipe he solders the connecting piece creating a leak proof Union these pipes will carry the heating fluid to the radiator keeping passengers comfortable during the cold [Music] season they install the fuel tank this bus runs on clean diesel fuel a low sulfur fuel that reduces harmful em and because buses need to run all day without stopping for gas the tank holds about seven times as much fuel as an average [Music] car the roof and sides of the bus are made of fiberglass to prevent corrosion workers install them with glue rather than screws or rivets this articulated bus uses a 330 horsepower engine the engine arrives at the factory already assembled 4:00 a worker installs it in the engine compartment at the back of the bus later he'll connect the engine to the drive shaft transmission and exhaust system still supported by a dolly the bus moves down the production line at this point the wheels have been installed so the bus can be driven from one workstation to the next they now install the windows handling them with suction cups buses without air conditioning usually usually have sliding windows that open widely on air conditioned buses just a small top section opens an assembler checks the rubber around the window to make sure it's watertight they now install the seats these ones are made of molded fiberglass and upholstered with a stainproof velour likee fabric their construction makes it difficult for vandals to slash the seat with a knife here's how the finished bus looks when you stand in the central 5:00 section of the bus surrounded by the flexible accordion shaped walls a typical articulated bus has a wheelchair access ramp and it can carry up to 112 passengers
