In the 50s of last century, China's construction machinery industry was still in poor condition. Xuzhou heavy machinery factory was the founder of the new China engineering machinery industry. In 1957, the heavy-duty plant made the first 2 ton tower crane. This is the beginning of the xcu group's involvement in the construction machinery industry and the manufacture of large machinery equipment.
It is very difficult to start an undertaking
In March 1963, the heavy factory accepted the task of the first machinery department, after more than half a year's groping attempt, the first Q51 truck crane was successfully developed, and a new chapter of the development of the Chinese crane industry was opened. Over the next 20 years, the Q51 truck crane, as the leading product, produced 6652 units and exported to 22 countries. In 2003, the product was still in the service of the country.
Stick to innovation
During the period of the cultural revolution, under the paralysis of the whole industry production, a batch of technical personnel of the heavy factory stuck to the innovative posts, broke through the technology of hydraulic transmission and the special chassis technology of the crane, realized the technical transformation of the truck crane from mechanical transmission to hydraulic transmission, and filled the empty space of the large tonnage crane in China. White. Since then, heavy plants have gradually produced 5-50 tons of truck cranes and their special chassis production capacity, and become the first industry in the industry sales revenue of over 100 million yuan. The picture shows the first China QY16 full hydraulic truck crane successfully manufactured in 1979.
National Defense
Since 70s, according to the directive spirit of the central "conventional weapons people", the Q2-5H type 5 tons hydraulic truck crane, which has been produced by the crane and salvage car, has been developed successfully. In the next nine years, 365 units have been delivered to the army. The picture shows the QYJ5 full hydraulic multifunctional military rescue vehicle, which is awarded the two prize of science and technology achievements of PLA General Logistics Department.
Reform and Opening-up
In 1978, after the third Plenary Session of the 11th CPC Central Committee, the door of the country opened, and the people who had gone through ten years of turmoil realized the great technological gap with foreign countries. The national construction machinery industry began to take production as the center to restore the readjustment and rectify the work. At this time, Xugong has begun to aim at the most advanced level in the world to find the poor. In accordance with the twelve major resolutions of the party, Xugong actively cooperates with the National Economic Commission and has actively introduced a number of advanced technologies suitable for our country, especially advanced technologies that contribute to the technological transformation of enterprises, and try to digest and develop them. Through the introduction of digestion and absorption, Xugong heavy truck crane is developed from a single mechanical drive to a full hydraulic 5T-50T series, of which 20 tons of automobile cranes with a domestic rate of 80% have become the first large-scale mechanical and electrical products to be domestically made in Jiangsu Province, and a series of product varieties have been realized; in 1987, QYl6 steam Car crane is sold to the United States. It is the first time in the same industry to enter the United States market. It has opened a precedent for the export of 16 tons of car cranes to the developed countries, and was appraised by the state as a gold medal.
All these provide the basic primary equipment guarantee for the first twenty years of China's reform and opening up. All the domestic construction equipment must depend on the import difficulties to break.
