2022-11-29 11:23

Since Daewoo Forklift started operation in Yantai plant in 1998, it has produced and sold about 20,000 electric and internal combustion forklifts in the domestic market in the past 20 years. Among them, the 3-ton internal combustion forklift accounts for more than 80%. The 3-ton internal combustion forklift can be divided into three series: D20/25/30S-3 imported engine and gearbox of high configuration series, D20/25/30E,D20/25/30G, D20/25/30NXV imported engine and domestic gearbox of medium configuration series, D20/25/30F,D20/25/30NXP and other domestic engine and gearbox standard series products, as the parts of forklift maintenance service production area except D20/25/30S series performance parts are imported, the origin is South Korea, Japan and Europe and the United States foreign cooperation, The external matching of other series of products is basically domestic parts manufacturers, the supply channels of parts are relatively transparent, there is still a degree of information asymmetry in the interchangeability of parts for domestic models, design changes in the same series of products or the limitations of replacement parts number and other objective problems. As for the distribution and wholesale sales of Doosan Daewoo forklift parts, the distribution and wholesale sales of Doosan Daewoo forklift parts are mainly located in Yantai and the coastal areas where Daewoo forklifts and Doosan forklifts are kept. According to incomplete statistics, the annual sales scale of Doosan/Daewoo forklift parts through various channels is about 15 million (excluding tires and battery sets). The average annual maintenance spare parts cost of 1000 yuan per unit provides certain opportunities for the market channel development of Doosan Daewoo forklift spare parts through the delivery date and price factors of the "original parts" in the channel of Doosan Forklift truck main plant, the sales system and price policy. The interchangeability of domestic supporting spare parts is feed-back through the on-site information during the maintenance operation. Interchangeable alternatives have been developed to a large extent, expanding the relatively monopolistic supply channels. The epidemic and the trade and logistics exchanges between China and South Korea have greatly affected the delivery time of imported performance parts, which has been extended from 2 weeks to 2 months. The procedures such as customs clearance and epidemic prevention at the port have extended the delivery time to varying degrees. Therefore, the parts storage capacity, market demand forecasting ability and fund management ability of traders or service providers operating Korean forklift parts of Doosan Daewoo Forklift. The comprehensive strength, such as the value-added service ability of part number query, the ability of spare parts database construction and spare parts information reserve management, the warehouse scale and storage space and the logistics cost control ability, is particularly important in the present dowry business, and even directly affects the maintenance of the relationship between spare parts and customers. Besides the cost performance ratio, the most important factor is the delivery time of the parts, which directly affects the on-site maintenance progress and the loss of work. In the forklift service business of pursuing rapid response service, the delivery accuracy of the forklift parts, the quality of the parts and the delivery time are the decisive factors. As a professional service provider of Korean parts of Doosan Daewoo forklift, With more than 15 years of professional experience and taking shape in the construction of forklift parts information database, by the first half of 2022, it has completed the practical basic data collection and system integration management of service links such as parts pictures, installation size, key parameters, model brands and interchangeability information of more than 15,000 kinds of parts. As one of the core competitiveness of the parts business, it is necessary to have the system information management ability of the parts data, from the retail to the supply chain level of information data sharing, technical service consulting and other service solutions to improve the ability to face the future forklift parts service market professionalism, business organization structure, development vision, The industry trend of core business and informatization digital transformation, forklift parts resource integration, internal management improvement, online forklift parts drainage, offline professional services and integrity management, landing technical support and other multi-level parts business model has been transformed and transition from selling parts to providing parts service solutions.


Daewoo forklift has the following types of vehicles in the domestic market:

· Diesel forklift: 25/30 D20 / s - 2, D20/25 to 30 s - 3 series, vehicle parts basically for imports, frame body for domestic welding processing production, from the door frame system, multi-channel valve of the hydraulic, lifting oil cylinder, steering cylinder, steering gear, gear pump, gear box, before and after the bridge, engine, electrical wiring harness, etc

· Diesel forklift: D35 / D40S/D45S/D50SC series, D50S D60S/D70S series, the D100 D120 / D150S series, from 5 to 15 tons models based on caterpillar technology foundation, in the domestic ownership of more than 300 units

· Gasoline/LPG forklift: the G20 25/30 / e series forklift, main is equipped with mitsubishi G424 liquefied gas or petrol engine, imported gearbox, partial performance parts and D20 s - 3/25/30 series have interchangeability and general, less market ownership

· Electric forklift (car balance weight type) B15S B20S/B25S/B30S - 2, B15S / 20 25 s/s/s - 3 series, vehicle imported and the domestic assembly model, general equipped with direct current control system in Italy

electric reach forklift (station car and car type) BR13/15/15 / s, 20/25 BR14JW/jw / 20 jw 16 models, are all imported from the vehicle


The above models are the main series of Daewoo forklift products used to be sold in the domestic market. The supply of related parts is basically available at present. Except for some discontinued DC motors, which have been discontinued for more than 15 years, the future supply of parts will mainly be recycled or used Daewoo forklift parts, which can meet the maintenance requirements and reduce maintenance costs


Doosan forklift has the following models in the domestic market

· Diesel forklift D20/25/30 / se series (imported engine and gearbox), 35 g D20/25/30 series (imported engines are domestic and outside), D20/25/30/35 f series (full localization series), D50/70 g series (imported engine) D50/70 n series products (OEM), etc., The actual service life cycle of the products in the market is far lower than that of the similar products of Daewoo forklift truck. Doosan diesel forklift series products, which have entered the circulation of second-hand forklifts too early, especially the SE series models with imported transmission configuration, have technical difficulties in maintenance, and the supply price of · Gearbox parts is relatively high. Mainly reflected in the oil supply pump and torque converter, transmission valve plate and front and rear inlet solenoid valve and other major performance components

· Electric forklift B15/20/25/30 se series, imports of motor and imported brands of electric control, other components are basically is given priority to with domestic components, Italian SME electronic overheating fault problems and subsequent replacement Curtis controller, etc. Mainly is the control of the two brands, the ac motor for imported brand, country of origin or for OEM products, The supply of domestic front and rear axle and hydraulic system accessories is relatively simple. The discontinued SME controller and motor need to be ordered now, and the delivery time is more than 1 year

· Electric stacker/electric tractor and economical drive type electric balance weight forklift: basically is given priority to with OEM mode of production, accessories and entrust the exchange of products homogeneity and general manufacturing enterprises imported cars electric forward type BR15/18/20/25 s - 5 full communication series, D110S D130S/D160S - 5 series and so on are all imported from of the vehicle


The appearance design of domestic models of Dooshan forklift truck is frequently changed, and there are many kinds of cover, side cover, plastic cover plate of instrument panel and workbench, and upper and lower cover plate of steering column. It is difficult to order replacement parts after daily damage. Some models have a variety of steering strings, for example, the rear axle of B30SE model is divided into multiple external supporting facilities and specifications. In the process of daily rear axle disassembly, maintenance and replacement of scattered parts, there are often problems of ordering errors or shortages. The replacement of the whole rear axle assembly brings great maintenance cost pressure to forklift customers. For similar parts, Yantai Huashen forklift has accumulated rich experience in supplying parts and collecting basic data. We can provide pre-sales service and technical support for customers who purchase parts. According to the forklift model and series number, we can check the matching parts part No. The accuracy of parts supply has been greatly improved, and the improvement of maintenance efficiency and satisfaction has played a positive role in promoting the continuous parts trading. The logic behind this is the professionalism and market flexibility of Doosan Daewoo forklift parts product database.
