A concrete mixer typically using a rotating drum to mix a combination of water, gravel, and cement to form concrete. Some construction sites use small, portable mixers to mix concrete on-site. There are also much larger industrial concrete mixtures that prepare concrete for large-scale commercial projects. The concrete mixer truck for sale is somewhat of a middle ground between these two options. It can mix large batches of concrete and is able to transport that mixture across long distances.
The Oldest Concrete Mixer Trucks
The very first self loading concrete mixer for sale weren’t actually trucks at all. They were portable, horse-drawn mixers attached to a carriage. The oldest design currently on record dates back to 1904 and was created by Richard Bodlander. The drum used for mixing the concrete replaced the front wheels of the carriage. The drum was constantly rotated as the horse moved, thus mixing the concrete during the travel time. The large size and weight of the machine severely reduced the speed of the horse.
It would be 12 years later before the first motorized concrete mixer truck was designed. The design was attributed to Stephen Stephanin, who is well-known for inventing the wrench. The 1916 patent was originally rejected. The design remained in limbo until he reapplied in 1928 and finally gained the official patent in 1933.
The controversy surrounding his original rejected patent created some confusion. Ackert Bickel is often credited with the invention of the concrete mixer truck due to his approved 1920 patent of a similar machine.
All of these inventions helped shaped the modern concrete mixer truck for sale in Sri Lanka and the modern construction industry as a whole. These trucks allow suppliers to deliver mixed concrete to a worksite on the same day as the order. They have a large capacity and can mix large batches of concrete far faster than a portable mixer. They have helped improve the efficiency and workflow of constructions site around the world.
One Machine With Two Functions
The concrete mixer truck is such a beneficial invention because it serves two key functions. First, it facilitates the transport of large batches of cement to any location with access to a road. Second, it is able to mix large batches of concrete at a greater rate than standard portable mixers. When you combine these functions together you are able to cut the time in half and have large batches of concrete ready to pour as soon as it arrives.
The barrel of the mixer truck manufacturer in Sri Lanka contains rotating blades that keep the mixture moving for the entirety of the trip. This prevents the concrete from hardening and becoming unusable. The barrel can then be shifted and the same blades are reversed to easily pour the concrete mix through an attached chute.
A concrete mixing truck from AIMIXPlant.lk can still be useful even in construction sites where the truck would not have direct access to the necessary area. The mixture can be unloaded through concrete pumps that are capable of pumping the mixture onto the jobsite. Concrete mixing trucks are one of the most important industrial inventions of the 20th century and will likely remain commonplace for centuries to come.
