The lifting weight of SANY 12 ton truck mounted crane cannot meet the requirements of special environments.
The price of SANY 16 ton truck mounted crane is too expensive, and the emergence of 14 ton truck mounted crane has undoubtedly solved the needs of users. In terms of lifting weight, The lifting weight of the 31 14-ton crane is 2 tons more than the 12-ton crane.
I feel that the four-section boom is too short. You can also choose a five-section boom. From the price point of view, the 31 14-ton truck-mounted crane is cheaper than the 16-ton truck-mounted crane.
About 10,000 USD. In terms of price, the 14-ton truck-mounted crane occupies a strong position. Of course, if the maximum lifting weight needs to reach 16 tons, it is another matter.
After all, the lifting range of a 16-ton crane is more than 12 tons and 14 tons. Extensively, let’s take a look at the basic parameters and lifting operation parameters of the SANY 14-ton truck crane.
Three-one 14-ton truck-mounted crane can choose four-section or five-section boom, crane model: SPS35000, adopts polygonal boom body, four-section boom working radius 15.4 meters, lifting height 17.4 meters, full extension can lift 1.6 tons, The working radius of the five-section boom is 18.5 meters, the lifting height is 20.5 meters, and the full extension can lift 0.6 tons.
As can be seen from the above figure, the length of the four-section boom and the five-section boom when the boom is fully extended, the height difference is about 2 meters, the hydraulic system The flow is 70L/MIN, the oil supply is the same, the lifting speed is quite fast, and when multiple lifting actions are operated at the same time, the oil supply system is not inferior, the lifting is smooth, the front hydraulic outrigger is standard, and the span is fully extended Up to 6 meters, stable and safe operation.
The lifting weight of the SANY 14-ton truck-mounted crane is related to the elevation angle and boom length. The boom length remains the same. The greater the elevation angle, the greater the lifting weight, and the elevation angle remains the same.
The longer the boom extends, the smaller the lifting weight. Take the above figure 31 as an example of a 14-ton five-section boom. The boom can reach 18.5 meters when fully extended. It can lift 0.6 tons in the horizontal direction, 1.3 tons at 30 degrees, 2.4 tons at 60 degrees, and 4.2 tons at 75 degrees. , Because this five-section boom is 18.5 meters long and has a wide lifting range, it can be lifted on both sides or the back of the cargo box, and the operation is convenient and flexible.
The 314-ton truck-mounted crane is often equipped with a rear eight-wheel chassis or a front four-back eight-wheel chassis. For such a high-end crane with a rear eight-wheel chassis, only Dongfeng Tianlong can do the job.
