1. Engine power: ① small loader with power less than 74kw. ② Medium loader with power of 74 ~ 147kw ③ large loader with power of 147 ~ 515kw ④ extra large loader with power greater than 515kw

2、傳動形式：①液力—機械傳動，沖擊振動小，傳動件壽命長，操縱方便，車速與外載間可自動調節(jié)，一般在中大型裝載機多采用；②液力傳動：可無級調速、操縱簡便，但啟動性較差，一般僅在小型裝載機上采用；③電力傳動：無級調速、工作可靠、維修簡單、費用較高，一般在大型裝載機上采用。

2. Transmission form: ① hydraulic mechanical transmission, with small impact vibration, long service life of transmission parts, convenient operation, and automatic adjustment between speed and external load. It is generally used in medium and large loaders; ② Hydraulic transmission: stepless speed regulation, simple operation, but poor starting performance, generally only used on small loaders; ③ Electric drive: stepless speed regulation, reliable operation, simple maintenance and high cost. It is generally used on large loaders.

3、行走結構：①輪胎式：質量輕、速度快、機動靈活、效率高、不易損壞路面、接地比壓大、通過性差、但被廣泛應用；②履帶式：接地比壓小，通過性好、低、穩(wěn)定性好、附著力強、牽引力大、比切入力大、速度低、靈活性相對差、成本高、行走時易損壞路面。

3. Walking structure: ① tire type: light weight, fast speed, flexible, high efficiency, not easy to damage the road, large grounding pressure, poor trafficability, but widely used; ② Crawler type: low ground pressure, good trafficability, low stability, strong adhesion, high traction, high specific penetration force, low speed, relatively poor flexibility, high cost, and easy to damage the road surface when walking.

4、裝卸方式：①前卸式：結構簡單、工作可靠、視野好，適合于各種作業(yè)場地，應用較廣；②回轉式：工作裝置安裝在可回轉360°的轉臺上，側面卸載不需要調頭、作業(yè)效率高、但結構復雜、質量大、成本高、側面穩(wěn)性較差，適用于較俠小的場地。③后卸式：前端裝、后端卸、作業(yè)效率高、作業(yè)的性欠好

4. Loading and unloading mode: ① front unloading type: simple structure, reliable operation, good vision, suitable for various operation sites and widely used; ② Rotary type: the working device is installed on the turntable that can rotate 360 °. The side unloading does not need to turn around, and the operation efficiency is high, but the structure is complex, the quality is large, the cost is high, and the side stability is poor. It is suitable for small sites. ③ Rear unloading type: front-end loading and back-end unloading, high operation efficiency and poor safety

1、機型的選擇：主要依據(jù)作業(yè)場合和用途進行選擇和確定。一般在采石場和軟基地進行作業(yè)，多選用輪胎裝載機配防滑鏈；

1. Selection of machine type: it is mainly selected and determined according to the operation occasion and purpose. Generally, the operation is carried out in quarries and soft bases, and tire loaders with anti-skid chains are often used;

2、動力的選擇：一般多采用工程機械用柴油發(fā)動機，在特殊地域作業(yè)，如海拔高于3000m的地方，應采用特殊的高原型柴油發(fā)動機；

2. Power selection: generally, diesel engines for construction machinery are used, and special plateau diesel engines shall be used for operation in special areas, such as places with an altitude higher than 3000m;

3、傳動型式的選擇：一般選用液力—機械傳動。其中關鍵部件是變矩器形式的選擇。生產(chǎn)的裝載機多選用雙渦輪、單級兩相液力變矩器。

3. Selection of transmission type: hydraulic mechanical transmission is generally selected. The key component is the selection of torque converter. The loaders produced in China mostly use dual turbine and single-stage two-phase hydraulic torque converter.

4、在選用裝載機時，還要充分考慮裝載機的制動性能，包括多個在制動、停車制動和緊急制動三種。制動器有蹄式、鉗盤式和濕式多片式三種。制動器的驅動機構一般采用加力裝置，其動力源有壓縮空氣，氣頂油和液壓式三種。常用的是氣頂油制動系統(tǒng)，一般采用雙回路制動系統(tǒng)，以提高行駛的性。

4. When selecting the loader, the braking performance of the loader shall be fully considered, including multiple in-service braking, parking braking and emergency braking. There are three types of brakes: shoe type, caliper disc type and wet multi disc type. The driving mechanism of the brake generally adopts a force adding device, and its power sources include compressed air, air top oil and hydraulic pressure. The commonly used air top oil braking system generally adopts a double circuit braking system to improve the driving safety.
