The ring chain electric gourd is a light and small crane. Its role is mainly to enhance heavy objects. Its carrying components are the circular chain from level 80. The types of ring -chain electric gourds include group hanging type, high -speed type, etc. You can distinguish them at the speed of improvement. For example, the DHP group hanging 5T increases at 0.18m/minute. The increase of the DHS 5T 5T is 0.9m/minute, and the ER 5T increases speed of 2.7m/minute. Therefore, when we choose the ring chain electric gourd, we can choose according to the speed we want to reach. Someone may have doubts here why the group hanging models are raised so slowly. Such gourds are generally used to increase objects with large weight and large volume. The speed is high and safe, and the synchronization of multiple control is good. Therefore, different types of gourds apply different working environments.
