Henan Dongqi Machinery Co., Ltd. is a domestic European standard crane manufacturer with independent intellectual property rights, mainly based on independent research and development, and learning from foreign advanced technologies and experiences. In recent years, the company has continuously introduced high-end processing equipment, and at the same time carried out school-enterprise cooperation with many universities such as Southwest Jiaotong University and Shanghai Jiaotong University. New European standard products have been continuously introduced on the concept of European cranes' energy saving, light weight, compact structure, small footprint, high performance, maintenance-free, low noise, safety first, and people-oriented concept.
The company covers an area of 240,000 square meters, with a total investment of 240 million yuan. The registered capital is RMB 123 million. There are more than 600 employees, including more than 150 management technicians and more than 20 senior engineers. 500 (sets) of various production equipment and testing equipment, and the annual comprehensive production capacity of cranes reaches more than 10,000 (sets). The company has technical cooperation with many European machinery manufacturers, such as British SZW company, German NORD company, German SIEMENS company, French Schneider Electric company and many other companies. It is committed to the innovation and development of European crane technology, and strives to build Dongqi cranes. Become an internationally renowned brand.
In recent years, the company's products have successively been awarded by Shanghai Electric Group, China Railway Combined Transport, China Railway Corporation, China Railway, China Railway First Bureau, China Railway Seventh Bureau, China Railway Tunnel Bureau, and China Petroleum Technology Development Corporation (the company is mainly responsible for all overseas investments of China Petroleum Group Project) and other large state-owned enterprises and state-owned enterprises, and has received multiple orders. Our company is a domestic private enterprise that has entered the Shanghai Electric Group with European-standard cranes after crane manufacturers such as Konecranes, Demag, and Francotech. At the same time, it has obtained multiple sets of large-tonnage, high-tech, and can fill cranes Large blank orders in the industry. Products are widely used in steel, electricity, petrochemicals, machinery manufacturing, military industry, warehouse logistics, papermaking and other fields.
The company's main products are: various types of European standard bridge cranes, gantry cranes, explosion-proof, metallurgy, European standard electric hoists, rail laying machines, fully intelligent truss industrial robots, etc. Some key core parts are imported from British SZW company original products. The production of structural parts is strictly in accordance with European technology standards, and the performance of the whole machine reaches the international advanced level.
Green, intelligent and efficient are the goals we are pursuing. We will provide you with a reasonable design solution, and use high-efficient technical and economic indicators to tailor-made high-standard European standard cranes for you.
Advantage 1: Break the design concept of the crane lifting mechanism and creatively apply the planetary gear reducer to the crane manufacturer of the lifting mechanism. The hoisting mechanism adopts direct connection type, which perfectly combines the motor, reducer, brake and drum. It effectively improves the transmission efficiency, greatly reduces various transmission parts required by the lifting mechanism, reduces noise, and at the same time the agency has independent intellectual property rights.
Advantage 2: Equipped with high frequency control of the whole machine mechanism, stable lifting and running (for various European standard single and double beam cranes: our company uses ABB frequency converter, which has its own lifting macro system. The frequency converter is 0 High-speed braking reduces the mechanical impact on the motor, reducer and structural parts. At the same time, it can extend the automation and intelligent crane, realize unmanned operation, remote monitoring, and achieve anti-sway function.)
Advantage 3: Low noise and maintenance-free (reduction of inspection time and maintenance cost) (Since the structure is simple, the number of supporting parts is small, which facilitates procurement in the later stage and also reduces inventory)
Advantage four: low energy consumption through frequency converter speed regulation, effectively reducing power consumption by 20% -30%
