1. With a long
history: DALIAN HUARUI HEAVY INDUSTRY GROUP CO., LTD （DHHI）
began to design and manufacture of bucket wheel stacker
reclaimer since 1966. So far, we have nearly 50 years history of
design, manufacture and development of stacker and reclaimer.
2. Large quantity of design and manufacture of the product: Up
to now r, DHHI has supplied about 730 sets of various stackers
and reclaimers to domestic and foreign customers.
3. Completed types and specifications of equipment: DHHI has
designed and manufactured nearly a hundred types and
specifications of the bucket wheel stacker & reclaimer.
According to the capability of the stacker and reclaimer, the
capability is from 100t/h to 15000t/h. Slew radius is from 25
meters to 65 meters. According to the function of machine, there
are boom type stacker, reclaimer and stacker & reclaimer,
circular stockyard stacker and reclaimer, gate-type stacker and
reclaimer, blending stacker, blending reclaimer, roller blending
reclaimer, gate-type blending reclaimer, bridge type reclaimer
and scraper reclaimer. According to the different type of
tripper car, there are moving type single tripper, fixed type
single tripper, the moving type double tripper, fixed type
double tripper and flexible lifting type tripper and etc.
According to the different luffing type, they can be divided
into partial luffing hydraulic type, partial luffing steel rope
winding type and the overall luffing hydraulic type and etc.
4. Cooperation with foreign famous manufacturing company: Since
the reform and opening-up, DHHI has the most times of technical
cooperation and communication with foreign industry. The
cooperation is critical to improve the design and manufacture
levels of DHHI, and to learn advanced technology and experience
from overseas so as to improve the quality of products. The main
cooperators are: MITSUI MIKE MACHINERY CO., LTD, MAN CO., LTD,
MITSUBISHI CO., LTD, KNAUER CO., LTD, Cayard Co., LTD,
ThyssenKrupp CO., LTD, Voestalpine Co., LTD and etc. Large
amount of technical cooperation create the conditions of
technology improvement and development of DHHI product. DHHI has
learnt foreign advanced design and manufacturing technology
through nearly 30 times the internal cooperation.
5. Lots of export products: export to Brazil, Venezuela,
Argentina, Mozambique, Australia, Malaysia, India and other
countries. Main users are VALE and BHP. Most of exported
machines are large and ultra-large stacker and reclaimer.
6. Convenient transportation conditions: DHHI is located at the
coast of the Bohai ocean. Products can be transported by road,
rail, shipping. Especially for delivery of large equipments, it
has advantageous geographical conditions. Large products can be
entirely shipped, which will reduce the second time of the
assembling on site and this will greatly improve the quality of
the products.
7, has its own fabrication base and excellent manufacturing
equipment: DHHI has five manufacturing bases in Dalian, totally
taking up the area of 6 million square meters. High precision
equipment HEANYCNT 200 type CNC boring machine, PF - 200 H75KW
(IS) 315/250/250 x400 type CNC gantry boring and milling machine
and other equipments improve the machining precision. High
precision numerical control cutter blanking guarantees the
welding quality of weld pieces.
8. Excellent design team and advanced design methodology: DHHI
bucket wheel stacker and reclaimer design team consist of over
160 engineers. We have both old engineers with rich experience
and young engineers seizing every minute who design a large
number of advanced stackers and reclaimers each year. DHHI
bucket wheel stacker reclaimer design use Auto CAD for the
drawing design, and combine using 3D and 2D drawing. We also
develop integrated design software for stacker and reclaimer,
and we use the most advanced computer software I-DEAS, ANSYS
Microstran V9 to proceed with strength and stiffness analysis in
order to ensure the stiffness and strength of equipment and
fully guarantee the quality of design. In addition, we also have
3D modeling and analysis software: SIEMENS NX, material flow
simulation analysis software: DEM, dynamic simulation analysis
software, ADAMS, and the belt conveyor calculation analysis
software: Sidewinder.
9. Use technology standards: applying to different customer
group needs, we can adopt international standards, European,
Australian and Chinese standard for the design and manufacture
of bucket wheel stacker and reclaimer so as to meet different
design and manufacturing standards for different customer
groups. Mainly the standards include JB/T 8849-2005, JB/T
4149-2010 boom type bucket wheel stacker and reclaimer technical
conditions, ISO 5049/1: 1994 2. Mobile Equipment for Continuous
Handling of Bulk Materials Part1: Rules for the design of Steel
Structure, FEM SECTION II: 1997 and Australian standard
AS4324.1-1995.
10. Strict trial-installation process: DHHI carry out
trial-installation in the workshop as far as we can for bucket
wheel stacker and reclaimer. Trial-installation process is with
many sets of large gantry cranes so as to verify manufacturing
precision and maximally guarantee the correctness of all parts
of equipment when they arriving on site.
11. Capable of installation team: DHHI has its own installation
team that can organize the design, manufacture, installation and
commissioning work as one-stop services. We undertake turn-key
project.
12. Highly qualified: DHHI is a backbone enterprise of equipment
manufacturing industry in China with excellent qualification of
integrity. ISO9001 quality management system, ISO10012
measurement management system and boom type bucket wheel stacker
and reclaimer obtain local industrial products manufacturing
warrant issued by People's Republic of China national
administration of quality supervision and inspection bureau.
DHHI has strong capital and technical. DHHI came into the market
in Shenzhen stock exchange in 2012. Company is profitable for
many years with excellent economic efficiency.
