【正文】 ,light in weight,flexible,portable,and easy to tools are used on a very light assembly work and on heavyduty constrution speed and direction of rotation of air motors can be controlled quickly,and they can be adjusted to serve requirements by means of a control valve which throttles the flow of pressed air to the motors do not have a tendency to bee hot when they are air motor presents no spark hazard in explosive atmospheres。多斗裝載機(jī)的提升機(jī)把物料卸在傳送帶上，再由傳送帶將物料運(yùn)送到設(shè)備中。在筑路中，用于將砂子和礫石裝入烘干筒和攪拌機(jī)里。多斗裝載機(jī)適于磚廠、混泥土預(yù)制品廠及裝卸量大的火車(chē)站，也同樣適用于裝載松散5 物料。裝載設(shè)備有三種不同的形式，即前卸式、翻轉(zhuǎn)式和側(cè)卸式。還可以選 配動(dòng)力轉(zhuǎn)向及全天候駕駛室。 因?yàn)椴孳?chē)在硬路面上作業(yè)，因此，主要用于倉(cāng)庫(kù)并作為工廠物料的裝卸設(shè)備。既定卸載機(jī)用于從平板貨車(chē)或 敞蓬車(chē)上卸貨；氣動(dòng)卸載機(jī)用于卸水泥。輪胎裝載機(jī)機(jī)動(dòng)性能良好。單斗裝載機(jī)式通用機(jī)械，適用于多種條件下作業(yè)。 power steering and allweather cabs are options available. 3 Singlebucket loaders have a crawler tractor or a wheeled truck as a carrier mounting. The loader permits mechanization of loading construction and erection and work with the aid of change attachments,of which the main one is the bucket. The loading equipment is available in three modifications: frontend,overloading, and halfswing,jibtype. The frontend attachment provides also side overloading modifiactaion permits back unloading. Presently frontend loader with the positive displacement hydraulic drives for the attachment are most widely used. The output of multibucket loaders is 40 to 60 percent higher than of singlebucket machines at the same power rating,it is expedient to use them in brickyards,prefabricated concrete products plants,railway stations with large volumes of loadingunloading operatins and also for loading loose addition,they are suited for size grading of loose materials,for which purpose they are provided with special vibrating screens. Multibucket loaders are very efficient in unloading flatcars with side dumping of the handle loaders can be applied in the production lines of prefabricatde ainstruction products plants and also in road the latter case they are used for loading sand and gravel into drying drums and mixers. The working member of the loader is a screw feeder consisting of tow righthand and lefthand screws,which are arranged on both sides of a bucket the feeder rotates,the loaded material is delivered to the buckets to make the scooping scraper is secured underneath the screw elevator of the multibucket loader usually dischanges the material onto belt conveyers that deliver it to tiansport facilities. Some loaders discharge the handle material into tranport facilities through hoppers or chutes. 4 裝載機(jī) 在建筑施工中，材料的裝卸是用裝載機(jī)和寫(xiě)在機(jī)進(jìn)行的。實(shí)踐證明，在采石場(chǎng)和非金屬材料的倉(cāng)庫(kù)作業(yè)中，挖掘機(jī)的裝在效率要比裝載機(jī)高。多斗裝載機(jī)用于大型倉(cāng)庫(kù)、公路工程以及需要連續(xù)作業(yè)的工作。行走速度快，對(duì)公路路面和存活地面從不產(chǎn)生破壞作用。 叉車(chē)的主要工作裝置是用于裝卸整件貨物的叉子。這些裝載機(jī)是根據(jù)卡車(chē)的原理制造的，所以也叫卡車(chē)裝載機(jī)，他們以?xún)?nèi)燃機(jī)或帶有蓄電池的電動(dòng)機(jī)為動(dòng)力。 單斗裝載機(jī)以履帶拖拉機(jī)或輪胎拖拉機(jī)作為行走機(jī)架。前卸式機(jī)構(gòu)只允許從裝料的一側(cè)卸料；側(cè)卸式機(jī)構(gòu)是側(cè)面卸料；翻轉(zhuǎn)式機(jī)構(gòu)則從后面卸料。此外， 該機(jī)還適用于對(duì)松散物料的顆粒分級(jí)，為此，可以安裝一個(gè)專(zhuān)用的振動(dòng)篩。 該裝載機(jī)的工作機(jī)構(gòu)是兩個(gè)左右螺旋桿組成的螺旋給料器，安裝在斗式提升機(jī)的兩側(cè)。 有些裝載機(jī)用漏斗或料槽把物料送進(jìn)運(yùn)輸設(shè)備中。therefore,it can be used in oil refineries and other plants that the problem of example of explosive motors are used under wet and humid conditions,because there is no electric shock hazard. Among the many applications and users of pneumatic tools are: agricultural equipment manufacturers, aircrafe manufacturers, ammunition depots, automotive shops and plants, bakeries, boiler shop, can factories, cement plants, coal mines, construction work, cotton mills, cutstone plants, dairies, distilleries, forge shops, foundries and steel mills, furniture factories, many kinds of industrial pl
