Four-link Portal Cranes, known for efficient and stable material handling, adopt a four-link combined jib system, equipped with slewing, luffing, traveling, and hoisting functions. This model supports 360° full slewing, offers extensive operational coverage, and is designed to withstand high-intensity continuous operations. They are widely used for bulk cargo, general cargo, and container handling.
Single-jib portal cranes are known for efficient cargo handling at ports based on slewing, luffing, traveling, and hoisting functions. Featuring a compact structure with 360° full slewing capability, single-jib portal cranes deliver extensive operational coverage and heavy-duty continuous operation resilience. Compared to four-link portal cranes, they feature lighter deadweight, lower energy consumption, and reduced maintenance costs.
