应考虑需要测试材料拉力范围

Consideration should be given to testing the tension range of the material

拉力范围的不同，决定了所使用传感器的不同，也就决定了拉力机的结构，但此项对价格的影响不大（门式除外）。对于一般橡胶生产厂家，拉力范围在200公斤。因此一般选用单柱式的比较多。

The different range of tension determines the difference of the sensors used, and determines the structure of the tensile machine. But this has little effect on the price (except gate type). For the general rubber manufacturer, the tension range is 200 kilograms. Therefore, the general selection of single column type is much more.

与单柱式相对应结构的是门式结构，它是适应比较大的拉力，如500公斤或以上。用在金属材料试验多。速度0.01~500 mm/min左右。

The relative structure of the single column is a gate structure, which is suitable for a larger pull, such as 500 kilograms or more. There are more tests used in metal materials. The speed is about 0.01~500 mm/min.
