Understanding Counterweight Jib Cranes
Counterweight jib cranes are characterized by their simple yet robust design. A horizontal jib or arm extends from a central column or wall-mounted structure. A hoist mechanism travels along the jib, lifting and lowering loads. The counterweight, strategically positioned, balances the load and ensures stability during operation. This design ensures smooth and controlled movements, particularly beneficial in smaller spaces.
