The word Lorry means the truck with a flatbed with four wheels which some people believe came from the Railroad word for how the term came about overall.
Lorry as the vehicle has a long and pretty history which can be dated back more than 100 years ago and in the Yankie land, it is known as Truck instead but just really in America overall for most people who use the word instead of the correct word of Lorry. https://www.cardealerreviews.org/
The idea behind this vehicle was to allow people or businesses to be able to transport big things such as like fridges or freezers or big TV or 4 pieces Seater which for one person or 3 of them would be hard for them to transport even 3 miles but this transport allows all the problems of moving big or smaller items basically disappeared once this amazing transport system was created. https://www.techcrums.com/3-easy-guidelines-for-lowering-your-households-fuel-intake/
The first ever Lorry was created in Germany in 1896 by Germanic Automotive Pioneer Damlier which featured in it a 4 horsepower engine with 2 forward speeds and 1 reverse speed but there were trucks before this but this was the closest to the modern-day lorry we have today which is why it was such an important invention for life which even today we all need to respect and admire the man Damlier who designed this powerful life-changing device overall . https://www.techcrums.com/the-chevrolet-trailblazer-ss-and-the-jeep-grand-cherokee-srt-8/
The mid-1800 Steam Wagon which worked well in the past and as the name states it was powered by a Steam Engine but by the end of the 1800 the Diesel Engine was born but it took around 35 to 40 years for it to be adopted by Trucks around the world overall to make it fashionable for people using it in a mainstream way of life.
Trucks have to two main parts of which have a cabin and Trailer and a place where the driver can control the vehicle to allow it to move in a safe and efficient way to transport goods from A to B or C or another area and it has been designed to be lightweight when possible in regards to heavily loads
The idea of why they are preferred lighter is to save on the cost of fuel since the weight of the vehicle can put up the cost of fuel from like $10 per litre of fuel with the light vehicle but with a heavy one, it could cost like $30 per litre in some cases for why companies need to focus on light transport or ways to decrease the costs to keep the business running in profitable way overall.
The biggest users of trucks would be supermarket chains like Tesco or Walmart or ASDA or someone else who needs the trucks to supply the foods to customers all around the world .
A Truck can allow you to transport in one trip in some cases enough to fill a full supermarket or at least replace the stock which have being sold overall or replace possible stolen goods overall.
