The lifting galvanized block with one pulley is widely used in installation works and is mainly used to change the direction of movement of the rope. The block consists of a galvanized case with a shackle and one pulley. The lifting unit with a nylon pulley is best suited for working with soft synthetic (nylon, polyamide, polypropylene) or organic (hemp, sisal, jute) ropes.
