To determine the weight lifting tonnage winch you want to buy.

二 确定卷扬机提升速度

Two determine the hoisting speed winch

确定您要求的提升速度，是每分钟多少米，相同提升吨位的卷扬机因提升速度的不同价格也会差很多。

Make sure you require to enhance the speed, is how many meters per minute, the same lifting tonnage winch hoist speed because of different price also will be much worse.

三 确定电机类型

Three to determine the type of motor

电机类型分为起重电机和普通电机。相同吨位的卷扬机可以采用普通电机制作也可以使用起重电机制作。但是起重电机适合更多的适用范围，价格也比较高。

Motor type is divided into lifting motor and general motor. Hoist the same tonnage of a common electric motor production can also use the lifting motor production. But lifting motor applicable scope more, the price is relatively high.

四 确定钢丝绳类型

五 确定卷扬机卷筒的容绳量

Five to determine the amount of rope winch drum
