What is the lifting system called that features two towers and a cross beam for lifting long equipment?

The lifting system that features two towers and a cross beam for lifting long equipment is a jin pole. This type of system is specifically designed for hoisting heavy items, particularly in construction and industrial settings, where its structure provides stability and support for lifting long loads that traditional cranes may have difficulty with. The two towers help distribute the weight securely, while the cross beam serves as the pivotal point for lifting operations, allowing for effective maneuvering of long equipment in tight spaces.

While cranes are also used for lifting heavy materials, they typically have a single boom that extends out and may not solely rely on the two-tower design. Hoists are devices used for lifting or lowering loads but can vary widely in their configuration and do not specifically refer to the two-tower design. Scaffolds are temporary structures used to support a work crew and materials during construction, not lifting systems for heavy equipment. Therefore, the jin pole is the most accurate term for the described lifting system.
