The model of the chain block is HSZ-C 0.5, HSZ-C 1, HSZ-C 1.5, HSZ-C 2, HSZ-C 3, HSZ-C 5, HSZ-C 10, HSZ-C series chain blocks are products which improved on the basis of HSZ series. They have higher efficiency and better performance than HSZ series. They are characteristic of their advanced designs and accuracy shapes. The chain block is easier to connect with side plates, thus the whole machine抯 stability is better strengthened.
