The 220 volt electric hoist can be used with various types of lifting machine frames. Its load capacity ranges from 500 kilograms to 3 tons. It is important to note that it comes in single rope and double rope configurations. The single rope hoist has a faster speed but smaller load capacity, while the double rope hoist has a slower speed but larger load capacity. The length of its steel wire rope is selectable between 12 and 100 meters. For the 12 meter steel wire rope, the standard load capacity applies; beyond 12 meters, the load capacity decreases, meaning the longer the steel wire rope, the smaller the load capacity. Therefore, when using it, one should first read the instructions manual and use it according to the required load capacity to avoid overloading.
