As an early important manufacturer of special heavy vehicles in China, Hanyang truck has always been an important brand for military and heavy transport. But today, it is hard to see hanyang's civilian truck series on the road. In fact, in the 1970s and 1980s, Hanyang also made a series of civilian truck products. A few days ago xiaobian on the Internet found two hanyang special tractor old data photos, very precious.
According to the introduction, hanyang Special Automobile Factory production history of military vehicles can be traced back to the 1960s. At that time, the factory completed the trial production of torpedo transporter, thus stepping into the ranks of military production. Subsequently, Hanyang developed missile transporter, boat bridge vehicle and other military vehicles. In the 1970s, hanyang successfully developed the HY470 25-ton 4X2 heavy-duty semi-trailer in 1972 and the 50-ton 6X4 tractor in 1979 as the shortage of weight and lightness of China's automobile industry became increasingly prominent.
In the 1980s, Hyang developed the HY472/480 all-drive special tractor based on the development of the 50 ton tractor for civilian use and the experience of Germany's FAUN.
Hanyang HY480 is in the form of 8x8 drive, while HY472 is in the form of 6x6 drive. Both vehicles are of military and civilian use. Military vehicles and civilian vehicles are only different in some parameters, which are generally used in conjunction with semi-trailers.
The two models are driven by double front control, which can be flipped forward for maintenance of engine and other parts. There are 1 driver and 1 passenger seat, and 1 sleeper or 4 passenger seat in the rear.
In terms of engine selection, the HY480 adopts the air-cooled V-12 cylinder KHDBF12L413FC engine produced by Huachaidaoetz Company with the introduction of German Deutz KHD technology, with a larger output power of 3.73 million (507 horsepower) and a larger torque of 1,618 nm. In the 1980s, this dynamic would have been considered a violent machine.
As the total traction weight of HY472/480 special tractor exceeded 100 tons, hydraulic torque converter was used in the selection of gearbox, which was also the important reason why many state-owned large automobile transportation companies took Hanyang special tractor as large tractor. The gearbox is from German ZF company. The model is 4S150GPA+WSK400 hydraulic torque converter.
On the choice of vehicle braking system, hanyang HY472/480 standard all-wheel drive special tractor are far higher than at that time, all the domestic truck, double pipe air brake, brake valve all adopt the original WABCO, three sets of independent brake (main braking: operating pneumatic foot, hand brake: spring brake, the expiration for rear axle, auxiliary brake: engine exhaust brake). And these two special tractors with hydraulic torque converters also come with retarders!
Of course, in addition to producing monsters like the HY472/480 all-drive special tractor, hanyang Special Automobile Works in the 1980s also produced civilian versions of ordinary tractor models, such as the 20/40 container transport pictured here.
Later talk about the cab, it has been said that hanyang truck this cab is imitating the isuzu truck at that time, but this is an obvious mistake! This cab is based on the MITSUBISHI Fuso FP from the 1970s.
