Before diesel.

  • Steamrollers were rollers that flattened roads.
  • Steamrollers were powered by steam, although the term steamroller is still applied to the more modern rollers run by diesel.
  • Steamrollers flattened surfaces due to the mass of the vehicle and the cylindrical like drums, called rolls.
  • Steamrollers typically had three rolls and were controlled by gears.
  • Steamrollers are often seen in action at steam shows.

  • The most famous steamroller manufacturer was the British company, Aveling and Porter.
  • Britian was the largest steamroller producer and exported many of the machines to other countries.
  • Part of the M1 motorway, the highway from London to Leeds, England, was built by steamrollers.
  • Sometimes stemrollers had scraper bars fitted, that removed foreign material from the surface of the roll.
  • Steamrollers have been popular in movies, music and books, including the Thomas the Tank Engine and Friends series and Bob the Builder episodes.

It’s a bird! It’s a plane! No… It’s a blimp!

  • Blimps are aircraft with no inside framework used for support.
  • Blimps lift due to high pressure and helium pumped in the balloon.
  • The only solid parts of a blimp are the gondola, where the passengers are, and tail fins used for stability.
  • Blimps require propeller motors for steering mobility.
  • Some blimps were used for patrolling purposes for the United States Navy in the World War I period.

  • Blimps are commonly used for advertising purposes, and some blimps have 1000s of LED lights on them to shine messages.
  • Blimps are often deflated in transportation processes.
  • The term ‘blimp’ only refers to aircraft that free fly in the air.
  • The term ‘blimp’ is a mix of the original British word for blimp, limp, and the most common type of blimp class, B, thus creating ‘blimp’.
  • In 1925, Goodyear Tire and Rubber created the blimps we now know today.

Assault Amphibious Vehicle

Lets shorten Assault Amphibious Vehicle to AAV.

  • AAVs are used for land and sea military operations, generally around the beach.
  • The marines call AAVs “amtracks”, which is short for amphibious tractor.
  • An AAV was originally known as a “Landing Vehicle, Tracked, Personnel-7” or LVTP-7.
  • AAVs are generally equipped with a grenade launcher, a heavy machine gun, crew radios, and an intercom system.
  • AAVs have the capacity to hold 21 equipped troops, and four crewman – the driver,  commander, gunner, and a rear crewman.

  • AAVs were originally LVTD-7s which were first made in 1972 and converted to AAV-7A1s in the 1980s.
  • An AAV-7A1 weighs 29.1 tons (26.4 tonnes), and is 7.94 meters (26 feet) in length, 3.27 meters (10.7 feet) in width and 3.26 meters (10.7 feet) in length.
  • The AAV-7A1 can travel over speeds of 24.32 km per hour (15 mph) off road, 72 km/h (45 mph) on road and 13.2 km/h (8.2 mph) in water.
  • The replacement cost of an AAV is over two million dollars.
  • The Expeditionary Fighting Vehicle (EFV) was due to replace AAVs in 2015, but the plans have been cancelled.

It’s a bird!  It’s a plane!  No… It’s a helicopter!

  • Helicopters are aircraft that can fly horizontally, vertically and can hover.
  • Helicopters are a type of rotorcraft, which enables them to land almost anywhere, because the rotor blades allows the copter to fly vertically.
  • Helicopters are also known as choppers, whirlybirds and helos.
  • Helicopters have their origins in children’s flying toys, made from bamboo as early as 400 BC.
  • Many vertical flying ideas have been experimented with over the centuries and the term ‘helicopter’ was coined for a machine, that did not lift off the ground, in 1861.

  • The first ‘flight’ of a helicopter occurred in 1907, and the first full scale production helicopter was designed by Igo Sikorsky in 1942.
  • Helicopters are used for, but not limited to, transportation, military, health and safety, construction and tourism.
  • Helicopters move slower than most aircraft since the rotor blades’ speed depends on the speed of the copter.
  • If helicopters are unsafely operated, helicopters could go out of control or crash and end in serious consequences.
  • Up until 2012, the deadliest helicopter crash was a shoot down of a Mil Mi 26 over Chechnya, which killed 127 people.

Cement Truck

A cement mixer… on wheels!

  • Cement trucks are also known as concrete trucks.  They have a drum on the top of the truck which holds concrete.
  • Cement trucks mix concrete in the drum with sharp blades to prevent the concrete from turning hard.
  • Cement trucks typically pour concrete down long chutes to the site where it is needed.
  • The drum on cement trucks turn in one direction to mix the concrete, and the opposite direction to pour concrete out of the drum.
  • Long pipes and concrete pumps are used if the cement truck’s chute can’t reach the area that needs to be concreted.

  • The first patent application for a cement truck was filed by Stephan Stepanian in 1916.
  • Cement trucks generally weigh between 9,070 – 13, 600 kg (20,000 – 30,000 pounds).
  • Cement trucks carry approximately 18,100 kg (40,200 pounds) of concrete.
  • Most of the time, concrete needs to be delivered from a cement truck 90 minutes after been loaded in the truck.
  • Cement trucks typically have a steel barrel, but some new trucks use fibreglass.

Freight Train

They go on forever!

  • Freight trains are also known as goods trains and cargo trains.
  • Freight trains are locomotives that pull special freight cars.
  • Freight trains can be over 7 km (4.3 miles) long.
  • Freight trains are the most energy efficient type of transport for carting large and heavy quantities of goods long distances.`
  • Freight trains with over 100 cars are sometimes required to use more than two locomotives.

  • In 2001, the BHP Mt Goldsworthy in Western Australia, broke the record for the heaviest and longest freight train and weighed 99,732 tonnes and was over 7.3 kms (4.5 miles) long.
  • It is very important to track freight trains in case of emergency, so satellites are used for this purpose where communication is scarce.
  • Freight train cargo is often loaded into steel boxes for transport.
  • Even though it is illegal, some people purposely board freight trains to get a free ride or to avoid normal means of transport.
  • Freight trains generally pull coal, ore and grains as well as cars, food and other goods.
