What types of truck cranes are there?

With the continuous improvement of people's living standards, more and more things are used. Cars are an important means of transportation in our lives, but there are also various types of cars. According to different needs, the types of cars are also very different. So today, the auto repair editor will introduce you to the crane of the car. What are the types of cranes? The truck crane is a crane installed on the chassis of an ordinary car or a special car, and its cab and lifting control room are set separately. This kind of crane has the advantages of good maneuverability and fast transfer speed. The disadvantage is that you have to support your legs when you work, you can't drive with a load, and it is not suitable for working on soft or muddy ground. The chassis performance of the crane is equivalent to that of a truck with the same vehicle weight and meets the technical requirements of road vehicles, so it can be unimpeded on various roads. Most of these cranes are equipped with two control rooms for getting on and off, and the legs must be extended to maintain stability during operation. The lifting weight can be from 8 tons to 1600 tons, and the number of chassis shafts can be from 2 to 10. It is the most productive and widely used crane type. What are the types of cranes? Type introduction. There are many kinds of cranes, and their classification skills are different. Most of them are classified by lifting weight: light truck cranes (lifting weight less than 5 tons), medium truck cranes (lifting weight 5- 15 tons), heavy truck cranes (lifting weight 5-50 tons) and super heavy truck cranes (lifting weight more than 50 tons). Due to the use requirements, its lifting capacity tends to increase. For example, a large truck crane with 50- 1200 tons has been produced. According to leg types: frog leg, X leg and H leg. Frog leg span is 0? Only suitable for small tonnage cranes; X-shaped legs are easy to slip and are rarely used; H-shaped legs can realize large span, which has obvious advantages for the stability of the whole machine. Therefore, most hydraulic truck cranes produced in China use H-shaped legs. According to the transmission mode of the transmission device, there are three types: mechanical transmission, electrical transmission and hydraulic transmission. According to the rotation range of the lifting device on the horizontal plane (that is, the rotation range of the turntable), it can be divided into full-rotary truck cranes (the turntable can rotate 360 at will) and non-full-rotary truck cranes (the rotation angle of the turntable is less than 270). According to the structure of boom, it can be divided into folding boom, telescopic boom and truss boom truck crane. What are the types of cranes? Working principle Working principle: There is a rotating drum at the lower part of the boom, and a wire rope is wound on the drum. The wire rope passes through the pulley at the top of the next boom to pull out the last boom, and so on. When retracting, the drum retracts the wire rope reversely, and the boom retracts under its own weight. This drum is driven by a hydraulic motor, so you can see two oil pipes, but don't put them in the cylinder. In addition, the telescopic boom of some truck cranes is equipped with a nested plunger cylinder, but this application is rare. Due to the high cost of multi-stage plunger cylinder, the lifting arm bends elastically when loading, which has a great influence on the life of the cylinder. This concludes the introduction of mini-car maintenance series today. The above are the types of truck cranes introduced in the car repair series. Truck cranes are rare in most cities and are mainly used for some large-scale traffic activities. So it's ok for people who don't drive cranes to know something about this. I hope the introduction of the small car repair series can help you.
