Qingdao Municipal Party Committee Secretary visited Jiuhe Heavy Industry for inspection and research

Qingdao Municipal Party Committee Secretary visited Jiuhe Heavy Industry for inspection and research.


On the morning of March 18, Zeng Zanrong, secretary of the Qingdao Municipal Party Committee, and his party visited Jiuhe Heavy Industry for a visit and investigation. Han Shijun, secretary of the Jimo District Party Committee, and other leaders accompanied the investigation. 

Secretary Zeng Zanrong and his party first visited the standardized assembly production workshop of Jiuhe Heavy Industry. Zhang Mingqiang, chairman of the company, gave a detailed introduction to the production and manufacturing process of Jiuhe pump trucks, aerial vehicles and other products to the visiting leaders. Secretary Zeng asked in detail about the technical process, equipment research and development and production, and praised Jiuhe Heavy Industry for its efforts in technological innovation and product quality. 

Secretary Zeng emphasized during the investigation that Qingdao is an important advanced manufacturing base in the country, and Jiuhe Heavy Industry is a high-quality enterprise in Qingdao. He hopes that the company will continue to increase its investment in scientific research in the future, promote technological iteration and upgrading, forge the "diamond drill" of technological innovation, and strive to make Jiuhe Heavy Industry's special vehicles and engineering machinery into a nationally competitive brand. After visiting the production workshop, Secretary Zeng Zanrong also watched the operation demonstration of Jiuhe pump trucks, aerial vehicles, ladder trucks and other equipment.

Mr. Zhang expressed his sincere gratitude to Secretary Zeng Zanrong and his party for their concern for Jiuhe Heavy Industry. He said that this visit not only demonstrated the city and district leaders’ high attention to Jiuhe, but also reflected their attention and support for the development of local advanced manufacturing industry. Jiuhe Heavy Industry will continue to uphold the entrepreneurial spirit of innovation, pragmatism and efficiency, continuously increase R&D investment, enhance core competitiveness, and make new and greater efforts to promote the development of local economy and industry.

The secret of preventing the side turn of the pump truck

The tilt device for measuring the vehicle's level and the sensor for measuring the pressure on the supporting leg.The tilt sensor can sense the vehicle's level and send real-time horizontal Angle information, which can effectively avoid the tilting caused by ground slow decline.The function of the tilt sensor is to measure the tilt Angle of the vehicle in real time.The measurement accuracy of the tilt sensor is higher than 0.05 degrees.It can filter out small tremors caused by engine and pump tremors and trigger alarm when the Angle of left and right is greater than 3 degrees or the Angle of front and rear is greater than 5 degrees.


Key Practices for Small Loader Use and Care in the Initial Running-in Phase

After a small loader leaves the factory, it is generally stipulated that there is a running-in period (or running-in period) of about 12-50 hours, which is stipulated according to the technical characteristics of the small loader in the early stage of use. The running-in period is an important link to ensure the normal operation of the small loader, reduce the failure rate, and extend its service life. However, at present, some users ignore the special technical requirements of the running-in period of the new machine due to lack of common sense in the use of loaders, or because of tight construction period, or because they want to make profits as soon as possible. Some users even think that the manufacturer has a warranty period anyway, and the manufacturer is responsible for repairing the broken machine, so the machine is overloaded for a long time during the running-in period, resulting in frequent early machine failures. Even when the warranty period is about to come, long-term operation ignores maintenance, and the failure is exposed as much as possible to obtain the manufacturer's warranty. During the last warranty period, the equipment is normal, and after the warranty period, frequent failures will not only affect the normal use of the machine, but also shorten the service life of the machine. Therefore, full attention should be paid to the use and maintenance of the loader during the running-in period.


A Comprehensive Guide to Choosing the Right High-Performance Skid Steer Loader

The skid loader is known as the "sharp knife" product among small construction machinery. With its powerful functions and flexible and maneuverable characteristics, it is widely used in infrastructure construction, road and bridge, dock loading and unloading, municipal maintenance, sanitation, residential and other narrow construction environments... It is a multifunctional work platform that can meet different tasks. If the piston comes wear phenomenon, it will lead to the concrete cylinder wall and piston seal greatly reduced, and even appear the leakage problem.In addition, damage to the piston can affect the pumping capacity of the pump truck, as the concrete suction into the concrete cylinder decreases as the piston wears away.Piston general wear-resistant rubber, polyurethane, rubber and other materials, the diameter of the general than the cylinder diameter of 3-4mm.If excess concrete slurry is found in the tank, check to see if concrete pistons need to be replaced and if necessary.The piston lip should be pressed down first when replacing, and it should slide into the cylinder through one end of the cylinder.

Essential Principles of Aerial Platform Trucks Explained

Aerial work vehicles are special vehicles used to carry personnel, tools and materials to the work site and perform aerial work. Aerial work vehicles use a standardized automobile chassis as a walking mechanism to achieve walking (transfer) and carrying functions. In addition to the automobile chassis, in order to achieve the aerial work function, the composition of the aerial work vehicle also includes a power system, a working mechanism, a mechanical structure, a hydraulic and electrical control system, and a safety device.


Essential Knowledge for Ensuring Pump Truck Stability

1. The hydraulic system of the long-boom pump truck adopts a closed system, the closed circulation of the oil inside, the reversing of the swash plate, the unnecessary valve group is reduced, the pressure is not lost, and there is basically no commutation impact.


A Comprehensive Guide: Buying Your First Pump Truck

The type and structure of the building, site conditions and surrounding environment are the prerequisites for the purchase of pump models.In general, the above factors should be taken into consideration when choosing the type, and the amount of concrete pouring should also be taken into account, so as to ensure that the main performance parameters of the pump cars selected are in line with or slightly larger than the construction conditions.It should be pointed out that if the pump truck is not properly selected, the utilization rate will be low if the capacity is too high;If it is too small, it will not only fail to meet the construction requirements but also accelerate the loss of the pump truck.
