1、關鍵零部件技術發(fā)展滯后?？煽啃允菄a裝載機的主要問題，如國外發(fā)動機使用壽命8000h以上.液壓泵5000-8000h，液壓缸100-200萬次，而我國僅分別為300oh, 200oh-30001、和60--80萬次。與國外先進零部件相比，性能落后、質量不穩(wěn)定、可靠性低等，k套件落后己成為制約國內裝載機質量提高的主要因素。
Technical development of key components behind. Reliability is a major issue of domestic loaders, such as foreign hydraulic engine life over 8000h 5000-8000h, hydraulic cylinders 100-200 million,while the country were only 300oh, 200oh-30001, and 60 - 80 million times . Compared with foreign advanced components, performance backward, unstable quality, low reliability, k kit has become a major factor behind the loader to improve the quality of domestic constraints.
2、產品更新?lián)Q代周期長，產品技術含量較低。國外機電液信一體化、智能化、集成化、多功能等技術己成熟。國內輪式裝載機開發(fā)主要為仿制，跟隨國外現(xiàn)有成熟機型.大部分核心技術要依靠國外公司。
Product long replacement cycle, low technological content of products. Foreign Hydromechatronics letter integration, intelligent, integrated, multi-functional technology has matured. Wheel loader developed primarily for domestic imitation, followed abroad existing mature models. Most of the core technology to rely on foreign companies.
3、技術創(chuàng)新能力薄弱，市場快速反應能力差。新產品開發(fā)周期長，市場快速反應能力差，用戶需求得不到滿足，其原因是對技術創(chuàng)新是從市場、研發(fā)、生產到商品化的系統(tǒng)工程認識不足.以及技術創(chuàng)新機制效率不高。
Technological innovation capability is weak, rapid market response is poor. Long development cycle of new products, rapid market response is poor, the user needs are not met, the reason is the lack of technological innovation from the market, research and development, production and commercialization of systems engineering knowledge.And technology innovation mechanism is not efficient.
