Sany builds the first brand of LNG mixer truck to guide the energy reform of the construction machinery industry

With the application and promotion of natural gas energy in the field of residential life and public transportation, in 2009, a new concept was proposed in the construction machinery industry - natural gas (liquefied natural gas, hereinafter referred to as LNG)Mixer trucks。 This idea seems bold, but in fact it is very in line with the development trend of future energy use: the depletion of oil resources, serious coal pollution, immature electric heavy vehicle technology and other reasons, have brought many difficulties to the energy use of heavy vehicles in the future, and green, economical, safe and reliable natural gas if it can be promoted in the field of construction machinery, will benefit many parties.

Therefore, once the concept of "LNG mixer truck" was proposed, many domestic enterprises have invested in research and development, but due to capital, technology, gas source and other reasons, there has never been a representative product in the industry that can guide this energy reform. Today, as a leader in the construction machinery industry, Sany took the lead in launching LNG mixer trucks and focused on building industry brands, which undoubtedly injected strong impetus into the development of this new industry.

30% less than diesel vehicles to boost the energy reform of construction machinery

In 2011, Sany began to enter the field of natural gas mixer trucks, through a large number of customer visits, market research and resource surveys, Sany determined that LNG mixer trucks are the development direction of the future market, the country's environmental protection policy has a positive guiding effect on the development trend of the market, and customers are also in urgent need of such a high-efficiency and energy-saving product.

Based on Sany's strong strength in the field of mixer trucks for many years, through the joint efforts of all employees of Sany Lake Automobile Company, the prototype of Sany natural gas mixer truck was completed within one year.

In order to test their performance in an all-round and multi-level way, the R&D personnel sent these LNG mixer trucks to the customer's construction site for actual vehicle operation comparison, and recorded the volume, mileage, fuel consumption/gas consumption, fault information, etc. of the sample truck and the diesel mixer truck every day. After six months of tracking and comparison, the testers obtained *5656 hand information from the market and customers: Sany LNG mixer truck saves fuel costs by 30-35% per square kilometer compared with the same diesel mixer truck, and 10-15% compared with the same model of other brands.

The successful development of Sany LNG mixer truck and the major breakthrough in the field of energy saving have made everyone more confident in this product, but Sany did not rush to bring this new product to the market, but spent a whole year to improve the product.

"We are not for the concept of speculation and launch this product, in that case Sany will be no different from other companies that produce LNG mixer trucks, we want to build this product into a domestic * 5656 brand, into the same industry in the most stable, * 5661 efficiency, * safe energy-saving new products. At the same time, to provide customers with a full set of solutions, to achieve more saving, more profitable, more environmentally friendly, so that customers can buy and use without worries, so as to drive the construction machinery industry to the field of clean energy continues to develop. Zhou Wanchun, vice president of Sany Heavy Industry and general manager of Pumping Marketing Company, told reporters Sany's determination to promote energy conservation and environmental protection.

All performance indicators are in China*5656 and strive to build *5656 brand

At the beginning of 2014, Sany Heavy Industry LNG mixer truck was grandly launched, and this product has the technical advantages compared with other domestic brands. The equipment is selected from the most mature LNG engine in China, which has been verified by rigorous experiments, has strong reliability, and is suitable for various harsh working conditions such as high temperature, low temperature and high altitude.

"In addition to the use of the most advanced brand of the engine, the gas cylinder of the Sany LNG mixer truck is a famous American brand, and its vacuum insulation performance ranks among the domestic *5656, which reduces the volatilization of gas to a relatively low level and greatly reduces the loss and waste of natural gas." Zheng Libo, R&D engineer of Sany Lake Automobile Research Institute, told reporters.

LNG mixer tank cylinder is a device to store natural gas in liquid form, providing fuel for the vehicle driving and operation power, because the volume of gas cylinders configured by Sany LNG mixer truck is 5655 in the domestic same amount of mixer truck*5655, so the storage gas is more and the cruising range is long. "You can run 400 kilometers with one refueling, and the mileage that can only be achieved by adding two times to the cars of other companies, and one refueling of Sany LNG mixer truck is enough." Zheng Libo added.

In terms of vehicle safety, the generous Sany LNG mixer truck adopts a split front and rear platform without subframe structure, which realizes the double drop of the center of gravity and weight, and greatly improves the stability of vehicle driving and operation; The vehicle uses the automatic linkage technology of engine service brake and exhaust brake to effectively shorten the braking distance and reduce the wear of brake shoes, and improve the life of brakes. At the same time, Sany LNG mixer truck also adopts a number of patented technologies, which has formed a unique competitiveness in many aspects such as the service life of the mixing drum, the feeding and discharging speed, and the residual rate.

Cooperate with CNOOC and other enterprises to provide gas sources to provide customers with a full set of solutions

"Good products alone are not enough to guide the future development direction of the industry, only to build a complete industrial chain, in order to promote the continuous development of new energy in the field of construction machinery." Zhou Wanchun told reporters, "Customers now recognize the quality of Sany LNG mixer trucks, but they pay more attention to whether the gas supply of the vehicles can be guaranteed." In order to dispel the doubts of customers, Sany has set out to provide them with a full set of solutions. ”

It is reported that Sany Group established Sany Shengneng Equipment Co., Ltd. in 2013, specializing in the transportation and construction of new energy-related supporting equipment. Zhang Jie, executive director and general manager of Sany Shengneng, introduced this set of "tripartite cooperation" operation plan to reporters: "For customers who have purchased a certain number of Sany LNG mixer trucks, Sany will establish a skid-mounted station near its company or construction site, and we have reached an agreement with CNOOC, China Gas, ENN Gas and other large national gas supply units, which will provide gas sources, and Sany is responsible for the transportation and construction of natural gas, and contribute a complete set of solutions composed of gas sources, gas stations and LNG mixer trucks to customers. Let customers have no worries. ”

At present, the sales performance of Sany LNG mixer trucks is gratifying, and customers are satisfied with the products after using them, and they very much recognize Sany's new operation mode in the field of natural gas mixer trucks. With the advent of the era of natural gas, its application in large-scale construction machinery will become more and more extensive, and the new energy products represented by Sany LNG mixer truck are facing broad development prospects, and it is believed that this energy revolution will bring huge social effects to enterprises, customers and environmental protection.
