Based on the upgraded engine introduced by CNHTC Group at the beginning of this year and jointly with the most technically-accredited foreign design institutes, the fuel-efficient No. 2 engine is designed and upgraded according to the European mechanical development program and developed according to the characteristics of road transport in China A new generation of independent intellectual property system. After 6000 hours of uninterrupted machine testing , fuel economy II engine minimum fuel consumption reached 189g / kWh, has been in line with European standards. Through field testing table Ming, equipped with fuel-efficient engines of heavy vehicles. Ⅱ hundred kilometers than similar domestic products reduced by more than 10% torque reserve coefficient increases more than 30%.
Wang Donghui, deputy party secretary of China's heavy truck products in hair cloth scene said the face of soaring oil prices, almost all of the domestic automobile manufacturers have launched their own fuel-efficient products, some of which actually got real skills, but some just use User blind spot follow the trend of cognitive hype, which gives users the choice of suitable products increased difficulty. China's heavy truck launched the fuel-efficient II engine, not only can truly fuel-efficient users, but also its fuel-saving capacity in the country is also second to none of its kind.
Liu Wei, director of China National Heavy Duty Truck Technology Center, said the fuel-efficient engine Ⅱ number is all the more fuel-efficient, mainly because the first time the 8500 fuel injection pump , and to deflate valve supercharger instead of the original common Supercharger, the engine intake system and fuel supply system to achieve the best match, effectively improving the engine's power and economy.
Liu Wei introduced the core of the engine is the fuel pump, the current domestic Steyr other manufacturers are equipped with 7100 fuel injection pump, fuel consumption indicators remain high, can not be significantly decreased. China National Heavy Duty Truck and foreign companies jointly developed a 8500 pump, designed for heavy truck products in China. The 8500 pump has the unparalleled superiority of the 7100 pump. After rigorous testing, the 8500 pump has a significantly better fuel economy than the traditional 7100 pump. The engine bench test features a minimum of 3 g / kWh less fuel consumption and an additional torque reserve factor of 30 %, Acceleration, climbing, overload power is more robust.
Liu Wei to reporters forget such an account: Fuel economy II engine compared with the average engine cost price of about 500 yuan, while the fuel consumption per hundred kilometers to reduce 5 liters, assuming a car running 150 kilometers a day Can save 8 liters. According to the current market price of oil, the day savings of about 35 yuan of funds, less than a month, the cost of 500 yuan will be able to save the cost down.
It is reported that the introduction of new products at the same time, China's heavy truck sales hit record highs. From January to July this year, CNRT has produced and sold 35,385 heavy trucks , representing an increase of 39.12% as compared with the same period of last year with a market share of 20.37%. Its sales revenue reached 12.767 billion yuan, an increase of 77.4% over the same period of last year. Its profits and taxes were 930 million yuan, An increase of more than 200 times; exports of 4764 vehicles, foreign exchange earnings of 132 million US dollars, an increase of 9 times.
Mooring Winch is in ship berthing ships or boats moored in dock stopping also can run effectively, and has many functions such as in loading and unloading process to drift, supporting and positioning of the role, also in constant tension adjusting vibration compensation of deviations. The application of the mooring winch which is installed on the shore to load or unload the mooring winch is a constant tension adjustment characteristic.
Winch according to the power is divided into three categories: manual, electric, hydraulic.
Winch according to the function can be divided into: Marine winch, winch, mine winch, cable winch, etc..

Marine winch can be divided into: mooring winch, winch, winch, winch etc..
According to the drum form is divided into single and double drum.
In accordance with the distribution of the drum is divided into parallel double drum and front and rear double drum.
Main technical parameters
manual winches
Handle rotary manual winch drive mechanism is arranged on the stopper (ratchet and pawl), heavy things can be kept at the needed position. A safety handle and a brake should also be provided for the manual winch assembly or lifting of heavy loads. Manual winch is generally used in the area of small, poor facilities or no power supply.
Electric winch
Electric winch is widely used in heavy workload and the need for greater traction. Single drum electric winch (Figure) of the motor speed reducer drive drum, motor and reducer input shaft between the brake. In order to meet the needs of lifting, traction and rotation and other operations, there are double drum and multi drum device of the winch. General rated load of less than 10T of the winch can be designed to be an electric winch.
Hydraulic winch
Hydraulic winch is the main rated load of the winch, under normal circumstances 10T above to 5000T of the winch design into a hydraulic winch.
The structure is mainly composed of hydraulic motor (low speed or high speed motor), hydraulic normally closed multi disc brake, planetary gear box, clutch (optional), roll, support shaft, frame, press line device (optional). Hydraulic motor with high mechanical efficiency, large starting torque, and according to the requirements of working conditions with different distributor, can also according to user needs to design the valve group directly integrated in motor oil distributor, such as with the balance valve, the overload valve, high pressure shuttle valve, control valve or other performance of valve group, brake, a planetary gear box installed directly in drum, drum, a supporting shaft, frame according to the requirements of mechanical design, the overall structure is simple and reasonable and has sufficient strength and rigidity. Thus the series winch in the structure is compact, small size, light weight, beautiful appearance, and the like, in performance has the characteristics of safety, high efficiency, large starting torque, good low-speed stability, low noise, reliable operation, etc.. Worth mentioning is hydraulic motor high volumetric efficiency and the sun company quality balance valve to solve the winches are generally secondary decline and empty hook jitter phenomenon, making the upgrade of the series hydraulic winch, decentralization and smooth braking process, with a winch clutch can realize free downward. Integrated valve group is arranged in the valve plate is effectively simplified hydraulic system users. Because the series winch has the advantages, it is widely used in ships, railways, Construction Machinery, petroleum, geological exploration, metallurgy and other industries, its excellent performance has been recognized by the user.
Example: installation on the helicopter rescue equipment, main function is will persons or things to be lifted and lowered, its own power, can control the helicopter in maintaining a hover height, by hand winch control can retractable steel rope, to a person or thing lifted down.
