PURPOSE: A connection terminal of a trolley bar for a hoist is provided to improve mechanical durability and to reduce material costs per unit weight because connection terminals are injection-molded by using zinc. CONSTITUTION: A connection terminal of a trolley bar for a hoist is injection-molded and comprises bent surfaces in both sides to match with the shape of a reinforcing part formed in the center of a trolley bar. A pair of protrusions is molded in one side of the connection terminal connected to the trolley bar and is coupled to coupling holes(1'). The coupling holes are respectively formed in both sides of the trolley bar. |
