The truck with crane is mainly composed of key parts such as the vehicle chassis, crane, and cargo box. Hubei Dali Special Automobile Manufacturing Co., Ltd will briefly explain how to choose the truck-mounted crane from these three aspects.
The crane is one of the key components of the truck-mounted crane, which is directly related to the lifting capacity of the truck-mounted crane. Therefore, a good truck-mounted crane cannot be separated from a good crane.
Telescopic boom and folding boom cranes have their own advantages, mainly depending on their working environment.
The advantages of the telescopic boom are cheap and large working radius, which is more suitable for open working environments, so telescopic arms are more popular for individual users. As for the folding arm, its advantages are high work efficiency and can be equipped with auxiliary equipment, but the price is more expensive. And he folding arm truck-mounted crane is suitable for warehouses and factories with small working spaces.
The tonnage of the crane mainly depends on what kind of goods you are lifting.You can choose the tonnage of the crane according to your needs.It should be noted that the best lifting tonnage of a general truck-mounted crane is 70%-90% of the maximum lifting weight of the crane. When choosing, try to make the lifting weight have a certain amount of surplus, which will help extend the life of the crane. Also, you must be clear when the boom is very short, the maximum lifting tonnage is the lifting weight, if the boom is extended, the lifting weight will decrease in geometric multiples. For example, a 10-ton truck-mounted crane generally has a lifting weight of 10 tons within a telescopic distance of less than 3 meters, however, The lifting weight of 5 meters is only 5 tons, and that of 8 meters is 2.3 tons.
The common crane layout methods are mainly center-mounted and rear-mounted, both of which have pros and cons. The center-mounted type is convenient to choose the lifting position, and the rear-mounted type has better stability during the lifting process, but the biggest disadvantage is that it cannot carry overlong cargo. In general, telescopic boom truck-mounted cranes have relatively small tonnage, and most users will choose the mid-mounted type; folding boom truck-mounted cranes have large lifting tonnages and require high stability, so the rear-mounted type is widely suggested.
2. Chassi
The reliability of the chassis is related to the attendance rate of the truck-mounted crane, and more concerned about the income in our pocket, so choosing a reliable chassis is also the key to choosing the truck-mounted crane. When choosing, it is best to choose a brand with a large quantity, which is more convenient in after-sales and maintenance. The chassis must match the tonnage of the crane. A large crane on a trolley has poor stability and is prone to overturning, and the crane cannot perform its lifting capacity.
Can you modify the truck-mounted crane with the chassis of my own truck? The answer is certainly yes, but the manufacturer does not recommend that users use their own old chassis to modify. There are two reasons, one is that your chassis must have a crane refitting announcement, if not, it will not be able to go to the house. Second, the truck-mounted crane chassis is composed of a professional chassis with a truck-mounted crane, and the general chassis beam cannot withstand the huge pressure brought by the truck-mounted crane.
The cargo boxes of truck cranes are generally pallet-type, and flat-panel ones are also available, but they are relatively rare. What everyone cares about most is the length of the cargo box, which is generally based on the announcement of the truck crane. Generally speaking, 4x2 models have more compartments of 5.8 meters and 6.1 meters, and 6x2 or 6x4 models generally have compartments of 7.5-8.6 meters, what's more, the longest cargo box is 8.6 meters.
