On the excavator to prevent the theft of diesel oil, I have been stolen experience, I believe that many colleagues have the same experience. Thieves are really bad, diesel for engineering robots, that is true gold and silver, diesel for excavators that is the rations! But most of the excavators can only be parked in outdoor sites, how to prevent. Diesel oil is stolen? Personally, it is necessary to understand how thieves steal the oil if they want to conclude the anti-theft method.
The thief wants to get the diesel out of the tank, no more than three ways, first, from the seabed valve; second from the tubing, third, from the refueling. Below I have analyzed and analyzed how the three ways to guard against burglar.
1. Prevent thieves from discharging oil from the valve at the bottom of the sea
In general, there are valves in the bottom of a diesel engine, and some excavators need to be removed to see it. This valve is designed to release the water and impurities at the bottom of the tank. Although the diesel is released, the ordinary professional thieves do not steal oil from here because the valve is very small and the speed of the oil is very slow. When a box of oil is finished, it is estimated that the day is bright. But at the same time, in case of an amateur thief, it is not necessary to steal from here, and the driver also has some methods to prevent it. It is to pay attention to the top of the seabed valve in the diesel tank, so that the space can be reduced and the thief's oil pot or oil barrel can be put in no place.
Two, prevent thieves from putting oil from the tubing
The tubing comes from the bottom of the diesel tank and gets the oil water separator. As long as the thief turns the joint nut of the oil-water separator, the diesel will flow out of the tubing. The diameter of the tubing is small, and the 200L diesel oil is more than an hour, but it is much faster than the bottom valve. The oil-water separator is the side door of the excavator. Inside, if you want to lock the oil and water separator through the lock on the side door to prevent the diesel from being stolen, you are wrong, because the keys of each excavator brand are common, every excavator accessories shop can buy. The correct method of burglar theft should be, two excavators are closed next to the inside of the tank, and the tank must be inside, must be kept next to, not retained. He Duoyu's gap can not even get people to go in, let alone open the side door. But this is a technical job, and it is not recommended for the apprentice to operate.
Three, prevent thieves from pumping oil from the gas port
Most of the excavator's diesel oil is stolen. It is pumped through the gas port. As long as a common tubing is prepared, the diesel tank can be pumped clean, and the speed is as fast as the rate of refueling. If the thief brings the pump, it is faster. The way to prevent it is to weld a tube with holes in the gas port. The tubing can't be inserted into the tank. This method is becoming more and more popular. The excavators are well welded. After my excavator is welded, even the cover of the tank is not locked, and I have not been stolen.
In addition, if the conditions permit, usually stop the excavator at the time of the owner's house, or arrange a person to sleep on the excavator at night. When I am an apprentice before, I often sleep, but now the apprentice is not very willing to go. No oil in the box!
In fact, not only diesel, but also the battery and computer board, is also often stolen, the battery burglar theft, everyone will die the fixed screws of the battery, or to weld a frame, the battery package. The computer board is stolen to the owner of the main loss is the most serious, remember once, I and another import machine to work together, the second day work in the morning At the time, the importer could not move, the computer board was stolen, the rampant thief cut the wire of the computer board. Later, the Changsha police arrested a thief who had a computer board to steal a excavator. On the computer board, the owner of the computer would be more careful. In all of the 820-III cabs in Changsha, one of the iron stents was welded. It extends from the screen to the back and covers the cover of the entire computer board. It even forms a small industry. After customers buy a new excavator, there will be special soldering stents to find you. I have even seen a excavator with an inductor and a SIM card, which can send text messages when someone approaches a excavator. The designated cell phone.
The process of combating and preventing crime has never stopped. In the end, the way to guard against theft should be to tie criminals to law, and no one will be too peaceful to steal.
