In 2016, the new GB1589 regulations and the 921 regulations began to formally implement. The state attaches great importance to the governance of super, but the companies did not marginalize large-capacity tractors, but instead pushed them to more subdivided markets, such as efficient transportation. , large transport market, etc. In comparison with the 500-horsepower segment and the 400-hp segment, the 49-ton cargo was also pulled, and the 500-horsepower tractor unit saved more than 20% of the transportation time from the 400-horsepower tractor unit. At the same time, the 500-horsepower segment of the engine can achieve the best economical speed in high-speed transportation and reduce fuel consumption with greater reserve torque. At the conference, Gong Zuowei, director of customer engineering at Dongfeng Cummins, told the China Truck Network reporter: “Now users have a polarization trend in engine selection. Users with high timeliness requirements will continue to choose high-powered engines, and they have high requirements for cost performance. The user will choose a relatively small horsepower engine. From the current development of the logistics industry, the user demand for high-powered engines is still very high.†In addition, at the event site, among the four new vehicles released by Dongfeng Commercial Vehicles, there are The two models are equipped with ISZ engines. It is easy to see that Dongfeng Commercial Vehicles attaches great importance to the high-power market. In addition to Dongfeng commercial vehicles, the mainstream domestic auto companies such as FAW Jiefang, China National Heavy Duty Truck Group and Shaanxi Auto Heavy Truck Co., Ltd. all have 500 hp models. So, what are the technical advantages of the ISZ13L engine on the Dongfeng Commercial Vehicle? Let's take a look. First of all, the core of high-horsepower engines is horsepower. The power of the Dongfeng Cummins ISZ13L engine has been increased to 560ps, and the engine can reach a maximum torque of 2500N.m in the 1100-1400 speed range. In the industry's five 13L engines, it is well-deserved first in horsepower, first in displacement, and first in torque. . From the perspective of power data, it is believed that users who have focused on the timeliness of logistics transportation have already been tempted by them. Second, the reliability of the engine is an important factor. According to Gong, the Dongfeng Cummins ISZ series engine has developed a 40,000-hour rig test (equivalent mileage of 7.28 million kilometers). The test standards are based on Cummins heavy-duty engine strict ultra-industry 10% standards. Thousands of fatigue tests have passed the alpine, high-heat, and high-altitude tests to increase the life of the engine B10 to 1.6 million kilometers. This kind of high reliability is safe for users who travel long distances. Third, fuel consumption is the point of most concern for high-power model users. China Truck Network reporter learned that the Dongfeng Cummins ISZ engine uses Cummins (XPI) ultra-high pressure fuel injection technology, the maximum injection pressure of 2400bar, making the fuel more fully. In addition, the engine is also equipped with a variable fuel injection timing system, to ensure that the super power within the full range of speed, the engine can reach 80% of the maximum torque at 900 rpm, so that the engine runs most of the time in the fuel economy zone. "For common operating speed areas, Dongfeng Cummins has made fuel-efficient optimization and can achieve fuel savings of 2-3%," Gong told reporters at China Truck Network. According to the China Truck Network site, Dongfeng Cummins' ISZ13L series engines have been listed in batches since April 2016 and have produced more than 6,000 units. This is enough to prove the quality performance of ISZ series engines and the user's affirmation of the products. The official launch of the king of the 560-horsepower ISZ13L engine is undoubtedly the starting point for another growth in sales of Dongfeng Cummins. At the same time, the release of this model also adds a fast "horse" to the efficient transportation industry.
WinnerLifting deals with large ranges of hoists,including Lever Hoists,electric power hoists,and their accessories.
Basically hoist is a mechanical device used for lifting heavy duty loads of cargo and equipment.It is made by a pulley,which is held together by a closed chain,and the chain forms a loop inside,which makes easier to be pulled by hand power or electrical power.
You can get or even customize the hoist you need here,it would be great to put your own design or logo on each hoist,right?
And there are more we can do for you,like tackles,Beam Clamps,everything related to this lifting device.
