Liberation tanker

Liberated cars currently occupy the second largest chassis sales in China, and they have always been the first choice for car liberation in the Northeast. It is a strong opponent of Dongfeng Motor.

Liberation tanker with FAW liberation original chassis

Liberation car structure is sturdy and has a long service life. However, starting from July 13, 1956, the production of the old-type liberation car was 30 years, reflecting the single structure of China's auto products. In the past, one of every two Chinese cars that Mercedes-Benz had on China's land was liberated. In the 1950s, "liberation" was once the pride of the employees of the Changchun First Automobile Factory! But now it is "old". In 1980, in the wasteland of the outskirts of Changchun, tens of thousands of unsalable "liberation" platoons grew. On September 29, 1986, the 1281502 "liberation" vehicles opened the assembly line, and the 32-year old "liberation" was eventually suspended. At the end of the year, the Changchun First Automobile Manufacturing Plant successfully developed the 141 new model, which finally broke the “consistent system for thirty years”. The new "liberation" stood on the market! In September 1987, in the national competition, the new “Liberation” 141 was rated first-class goods; in the international tender, it was even linked to the middle three yuan. Changchun FAW, the old company, has entered the product development stage.

The change of "FAW" is the epitome of the development of China's auto industry. After more than ten years of reforms, China's auto industry has formed a new type of management system, product structure is becoming more and more reasonable, and replacements are accelerating. China's autos have begun to enter the international market in large quantities, and the auto industry has become an important pillar industry of China's national economy. Since the founding of the People's Republic, China has produced a total of more than 5 million vehicles of various types.

The initial Liberation brand car has CA10, CA10B, CA10C and other models for the rear axle drive, 6-cylinder inline water-cooled four-stroke gasoline engine, the maximum power of 70 kilowatts, load capacity of 4 tons, can be towed with 4.5 tons heavy trailer, the maximum speed of 75 kilometers / Hour, 29 liters per 100 kilometers. Later, it will produce improved CA15 type (including CA15K, CA15J, etc.), similar in appearance to CA10, with a load capacity of 5 tons, an engine power of 85 kilowatts and a maximum speed of 80 kilometers per hour. From 1956 to 1986, a total of 1.02 million vehicles were produced. In 1988, it was replaced by a new generation CA14I vehicle with a weight of 5 tons. It can tow a 6-ton trailer with a maximum power of 99 kilowatts, a maximum speed of 90 kilometers per hour, and fuel consumption of 22.5 liters per 100 kilometers. The car has excellent performance, good reliability, fuel economy and dynamics have reached the domestic advanced level, overhaul mileage doubled than the CA10 type, up to 200,000 km, can be converted into a variety of vehicles. In addition, Jiefang Auto also has CA34I dump trucks and CA93I semi-trailer trains.

Drivers are driving on snow and ice, use snow chains. Must reduce the speed, to avoid rapid acceleration and emergency braking, rapid braking and sharp cornering at high speed is strictly prohibited, otherwise the car is prone to slipping and tailing phenomenon and cause accidents.

When drivers are driving on rainy roads, the speed should be controlled. It is best not to exceed 35km/h. When driving in rain, rainwater may enter the brake drum and affect the braking effect. Therefore, the brake pedal should be lightly pressed to check the brakes from time to time. The effect is to avoid sudden braking and sharp turn, otherwise it is easy to cause slippage and slippage and cause accidents.

When the vehicle is stopped, the accelerator pedal should be relaxed to reduce the speed. Evenly step on the brake pedal. After the car stops, depress the clutch pedal to put the transmission into neutral, and pull the manual valve back to the end to make it in a braking state. Turn off the power (turn the start switch key back to the LOCK position). Avoid parked vehicles on steep slopes. If you have to park on the slope, you must use padding to fix the wheels. After driving, the exhaust pipe is in a high temperature state. Therefore, it is not allowed to park vehicles near inflammables such as withered grass. When naps in the car, the engine must be stopped. During a nap, accidents may occur due to touching the shift lever and pedals.

When a driver drives a tanker on a foggy day, he should light the fog light and drive at a low speed. Pay attention to the markings on the center line of the road and the taillights of vehicles driving ahead. If the fog is heavy, stop driving and park the car in a safe place. At the same time, turn on the distress alert switch so that both the front and rear left and right turn signals will flash at the same time. [1]

Tanker maintenance and repair

1. The first thing to understand is to master the main structure, performance, and tanker functions of tank trucks.

2. A tanker truck is usually composed of four parts: a special vehicle chassis (Dongfeng or Liberated Type II vehicle chassis), an oil tank body, a pipe network system, and a power take-off device.

3. The tanker driver must do a routine maintenance of the tanker. He must check, clean, and tighten the tanker before, during, and after the delivery. He should promptly discover the problems or safety hazards of the tanker. Do a timely manner to solve the problem and deal with it in time.

4. Check whether the oil tank body, pipe network, and valves are leaking or leaking oil before leaving the car. Whether the upper cover is properly covered or not, the amount of lubricating oil, the amount of fuel oil, the cooling water, the brakes on the hands and feet, and the steering device. Meters, lights, tire pressure, tire nuts, etc. [2]

5. The driver should pay attention to the problem of the tanker during driving.

1) The tanker checks the operation of each instrument while driving.

2) Check whether the steering system is working properly when the tanker is in motion.

3) It is not normal for the tanker to check the hand and foot brake while driving.

4) When the tanker is running, check whether the engine, chassis, and tank body are abnormally smelling and smelling during running.

5) Use the parking time to do the following inspections of the tanker: Check whether there is overheating of the front and rear brake drums, check the tightening of the tires and nuts, remove the inclusions in the tire tread, and check for oil leakage. Leakage, leakage, check the condition of the leaf spring, if the shaft bolt is loose, check the appearance of the oil tank and the pipe network system of the tanker.

6. The tanker regularly visits the Dongfeng Second Automobile Service Station and Liberation First Automobile Service Station to do chassis maintenance and maintenance work. The driver is reminded to strengthen the routine maintenance of the tanker and regularly check and replace the fire extinguisher on the vehicle. , in case of accidents.

7. The leakage of the tank, the related leakage has the problem of product quality, and there are reasons for its use. When a tanker truck is driving on a low-grade road, violent jolts cause impact loads near the tank support where the tank is connected to the chassis of the vehicle, and the impact of the oil in the tank on the tank during sharp turning or sudden braking. Causes greater stress between the tank and the tank support. For long-term use, fatigue cracks may occur at the stress concentration point.

8. When repairing the oil tank, when the oil tank leaks or leaks, it must not be repaired by electricity or gas welding without cleaning or cleaning.

First of all, to remove the residual oil in the relevant pipes and pumps, inject warm water containing detergent or washing powder into the tank, and start the tanker to run for several kilometers on the bumpy surface. Then drain the cleaning fluid with compressed air. Or steam blow clean. Open all valves and access covers to allow them to be parked in a well-ventilated location for more than 24 hours to ensure that there is no oil or gas in the tank before welding.
