Dump trailer. Personal transport

Trailers for cars, turning them into small trucks, are especially popular with rural residents and owners of summer cottages. And this is natural - they greatly facilitate the delivery of a wide variety of goods - sand and peat, cement and manure, bricks and gravel. The only pity is that they have to be loaded and unloaded exclusively by hand - with the help of a shovel.

I bring to the attention of readers a trailer dump truck with a tipping body. Having made one for yourself, you can get rid of problems when unloading it.

It seems that there is no particular need to describe in detail the design itself - it is quite traditional and such people have been told more than once on the pages of the "Modeler-Constructor". And yet, to begin with, a few words about the trailer device.

Its frame is welded from steel pipes of square section 40x40 mm, the bridge is from a SZD motorized carriage, using spring-hydraulic shock absorbers of a Ural motorcycle. The bridge is attached to the frame with the help of struts, also welded from square pipes.

The trailer is equipped with a standard ball hitch designed to accept a 50mm diameter ball.

The body is assembled from panels, each of which has a frame made of steel corners 30x30 mm and sheathing made of plywood 12 mm thick on MB screws with nuts. Two spars made of wooden beams with a section of 120x30 mm are attached to the bottom. Fastening the body to the frame - using a hinge, the mating parts of which are welded to the frame and screwed to the spars; in the front there is a latch resembling a conventional latch, which prevents the body from tipping over while driving.

Now about the main thing - about the design of the lifting device. It is pneumatic, driven by the exhaust system of the engine. Under the bottom of the body, between the spars, there are three car cameras in a case made of durable fabric - tarpaulin or synthetic canvas, attached with M5 screws to the rings from a steel corner on the bottom of the body and on the frame. All chambers are interconnected using threaded pipes, nuts, gaskets and washers, and a fitting is screwed to the bottom, curved in the form of the letter "L", on which a rubber hose is pulled. To raise the body, you need to put the other end of the hose on the exhaust pipe of the towing vehicle and "add gas". Two or three minutes - and the body will rise. To lower the body, just remove the hose from the exhaust pipe.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

tea and brain 09.08.2008

At the international symposium "Tea and Human Health", held in Washington (USA), Israeli researchers reported that the antioxidants contained in green tea can reanimate diseased nerve cells. Neurons in mice that were modeled for Parkinson's disease gained in size, their shriveled processes straightened out and made new contacts with surrounding cells.

The doses of antioxidants used in these experiments correspond to three to four cups of green tea per day for a person. American psychologists have shown that the rare amino acid theanine, contained in green tea, promotes concentration. The subjects had to watch symbols flashing on a computer screen and press a button when a certain symbol appeared. Before that, they drank a glass of pure water, water with theanine, water with caffeine, or water with both.

It turned out that the water itself, the addition of only theanine or only caffeine did not affect the results. But theanine with caffeine significantly improves attention, and this effect lasts for more than three hours. Doses of theanine in these experiments corresponded to 4-5 cups of tea, and caffeine - 3-4 cups.
