裝載機(jī)是在輪式或履帶式底盤(pán)上裝有帶鏟斗工作裝置的機(jī)械。 20世紀(jì)60 年代以前的裝載機(jī)，其功率和結(jié)構(gòu)強(qiáng)度均不大，主要用于裝載和搬運(yùn)松散物料。山東永保機(jī)械生產(chǎn)的的裝載機(jī)無(wú)論在結(jié)構(gòu)、傳動(dòng)、材料和輪胎等方面都有了改進(jìn)和提高，許多輪式裝載機(jī)已能用于露天礦、采石場(chǎng)和隧道等工程中。裝載機(jī)不僅可進(jìn)行土方工程作業(yè)，而且更換工作裝置后可以成為起重機(jī)或叉車等機(jī)械，同時(shí)還可以作牽引車用，是一種適應(yīng)性較強(qiáng)的一機(jī)多用的工程機(jī)械。裝載機(jī)的主參數(shù)是額定裝載重量。我國(guó)已經(jīng)制定了輪胎式裝載機(jī)產(chǎn)品系列和基本技術(shù)參數(shù)的標(biāo)準(zhǔn)。
Shandong is a mechanical bucket loader working device on wheeled or tracked chassis fitted with. 1960s before loaders, its power and structural strength are not large, mainly used for loading and transporting loose material. Shandong forever loader machinery production in terms of structure, transmission, materials and other aspects of the tire to improve and enhance many of wheel loaders have been able to open pit, quarries and tunnels and other projects. Loader not only earthwork operations, and after the replacement unit can become a crane or forklift and other machinery, but also can be used for towing, is an adaptation of a strong multi-purpose machine construction machinery. Main parameters of the loader is rated load weight. China has developed a series of wheel loaders products and standard basic technical parameters.
裝載機(jī)按行走裝置分為輪胎式和履式兩類；按車架結(jié)構(gòu)的不同分為整體式和鉸接式；按工作裝置結(jié)構(gòu)的不同分為有鏟斗托架式和無(wú)鏟斗托架式。此外，按卸載方式，又可分為前卸式、后卸式、側(cè)卸式和回轉(zhuǎn)式四種。最普通的是輪胎、鉸接、無(wú)鏟斗托架、反轉(zhuǎn)六連桿機(jī)構(gòu)前卸式單斗裝載機(jī)，如 ZL50 型。
Divided by walking device loader tire type and shoe type categories; different frame structure into the overall style and articulated; different structure divided into a working device bucket and non-bucket style bracket bracket-style . In addition, according to uninstall the way, can be divided into pre-dump after dump, side dump and rotary four. The most common is the tires, hinged, no bucket bracket, reversing the first six linkage detachable single bucket loaders, such as ZL50 type.
