Henry Plant is one of the earliest enterprises manufacturing belt, particularly in the development of large bandwidth, high band intensity, high-speed transport and special purpose conveyor has been in a leading position. FWX developed full-proof hydraulic downward belt conveyor awarded the Department of Mechanical Science and Technology Progress Award; Qinhuangdao dock was designed and manufactured by the maximum bandwidth, the highest of high-strength conveyor belt speed, won the Ministry of Machinery Industry Science and Technology Progress three prize; also developed China's first high-strength double-cut double-speed conveyor, to meet our high environmental, mining developed cold (-36 °) belt. Henry plant for the development of a new series of belt conveyors have made outstanding contributions. To catch up with the world advanced level, I plant in 1986 from Germany and Italy Lumei Ka Hancock company company introduced a belt conveyor idler rollers and the design, manufacturing technology, and make the corresponding transformation. After the introduction of technology into absorption, and now Henry plant bandwidth of high-strength belt extended from 0.5m to 3.0m; product installation using forms developed from fixed to mobile, displacement and vertical; product development capabilities from a single to a double cross sectional, two-speed, large angle; cold, high temperature, the next movement, explosion and other functions; maximum belt speed of up to 5m / s, the maximum reach with strong 4000kg/cm, maximum throughput up to 6000t / s, Henry factory production of high strength belt, in 1985 was named the Ministry of Machinery Industry quality products. 1988 was the only country with the ranks of silver products. 1995 Belt detection in Hebei factory production quality both Henry reached the national "Excellence" standard, Henry Plant is the only country with the industry that year was named "Excellence" of the manufacturer. The quality of the roller on the belt conveyor has a crucial operational reliability importance of this, I plant from Italy RULMECA company introduced a mine roller design and manufacturing know-how. The company is the world roller production group members, specializing in the design and manufacture of roller. Mine roller technology, which includes a variety of requirements for all roller design, manufacture. It can be designed according to the requirements of different load requirements in case needed to achieve any life requirements. No special instructions are usually the case; life is not less than thirty thousand hours on design and manufacturing. It has minimal start-up resistance, high efficiency, good sealing effect, a sealing structure which can not only dust, and can be waterproof, waterproof air. Rollers operating in the water after 24 hours without increasing its weight, its various performance indicators have reached West Germany the latest underground roller standard DIN22112-85 requirements. It therefore has the above properties, is by its agency of the decision. It is composed of dedicated high-precision welded steel roller bearing with punching through three yuan GMAW welding, precision light pull shaft. Large clearance bearings plus including third gear labyrinth seal including a total of five sealing composition. Roller assembly in our factory, including running-and resistance by the detection of a total of thirteen, including a fully automated assembly line stations effectively complete, so I plant life of more than 30,000 hours of roller, roller, the average resistance at around 1.6N whose index is much higher than GB10595-89 standards. So that machine running resistance coefficient f ≤ 0.022. Topline factory TD75 type, 1T type, 2T DTII type and type of standards, various models drum, there are light, medium and heavy-duty optional, there is no coupling and linkage. According to user requirements, and in the mid-1980s the company introduced from Germany KOCH drum proprietary technology and manufacturing techniques, and following the absorb and learn, the drum structure is more reasonable, life expectancy in more than a decade. Henry plant with foreign advanced industrial companies continue technical cooperation, it has advanced drum manufacturing process, the drum cartridge subcutaneous material, the use of optical tracking equipment, CNC cutting, to ensure the accuracy of the sizes of materials. Rollers are used in various forms can greatly reduce barrel weight and the weight of the roller shaft to prevent axial movement of the easy accessibility of the expansion sleeve coupling structure. Welded between each Mou adopt advanced gas (co2) welding and submerged arc welding. And the use of a unique aspect of Henry Plant sided molding welding welding method, greatly improving weld quality and reliability of welded parts. Simplified after welding to weld ultrasonic and X its testing and inspection to ensure weld quality, while simplified after welding, to be annealed to eliminate internal stress. After the roller assembly to be static balance test. Are the implementation of a variety of inspection standards GB10595-89, all with cast roller glue adhesive surface. Topline factory has now advanced carbonization technology and equipment, with a group engaged in curing technology engineers and workers, so it can guarantee a good quality drum plastic surface. In addition, the drum manufacturing precision is very high, the outside diameter of not greater than 0.2 mm radial runout (National Excellence standard 0.5 mm). Meanwhile, the drum outer plastic and is available in tape casting machine without removing the cylinder can be changed quickly and easily layer technologies. Henry plant conveyor competitions in the same industry in the country has won numerous awards. 1996 by the State Economic and Trade Commission, Ministry of Foreign Trade approved as mechanical and electrical products export base. 1998 through the IS09001 quality system certification. Products covering 29 provinces, municipalities and autonomous and metallurgy, coal, chemical, transportation, light industry and other industries. Equipment department of economic development has played a role of the pillars. Has assumed the Gezhouba hydro Project, Shanghai Baosteel, Qinhuangdao Port, Fushun West Open, Dexing Copper Mine, Junggar coal mine and other 40 national key projects of machinery and equipment manufacturing tasks. While products are also exported to the United States, Russia, Germany, Turkey, India, Japan and Southeast Asia, more than twenty countries and regions, the quality of products at home and abroad to give the user a great deal of trust and praise. Henry plant will continue the spirit of customer first, reputation, quality first principle, based on domestic focus on the world, and take the technology works, product rushed, quality and efficiency of the simultaneous development of the road, the better for both new and old customers.
