There are normally two basic types of sheaves: normal duty and heavy duty. Normal duty sheaves are used in less-complex operations. They can lift lighter objects and are protected using sheave guards. They're ideal for line speed and manual deployment. On the contrary, the latter can be used for more complicated operations.
From lifting hazardous equipment or material to die forging, heavy-duty sheaves can withstand all kinds of tough working conditions. Heavy-duty sheaves are also used in cranes for rigging, material movement, and hoisting.
