Product Introduction
Semi-Gantry Crane is a hybrid lifting system featuring a single leg on one side that runs on a ground rail, while the other side is supported by an end carriage traveling along an elevated runway beam mounted on factory columns. By eliminating the need for a second ground leg and rail, it maximizes floor space, reduces building infrastructure costs, and optimizes shop-floor workflows.

Product Advantages
Space-Saving Design
Blends the advantages of bridge and gantry cranes, allowing seamless integration against building walls or alongside existing overhead cranes without obstructing ground traffic.
Three-Dimensional Handling
Delivers precise material handling, cargo tilting, and positioning through vertical hoist movement, lateral trolley travel, and longitudinal crane motion along the rails.
Flexible Control Options
Supports ergonomic ground control (pendant/wireless remote) as well as fully enclosed operator cabins designed for high-visibility industrial environments.
Cost-Effective Efficiency
Lowers initial capital expenditure by utilizing existing plant structures on one side, significantly cutting steel structure costs and track installation overheads.
Typical Application Scenarios
Workshops & Warehouses
Frequently installed under existing overhead cranes on a lower level to handle dedicated workstation tasks without interrupting main crane operations.
Outdoor & Storage Yards
Ideal for outdoor loading/unloading zones, material yards, and rail marshalling yards where space adjacent to buildings must be optimized.
Heavy Manufacturing & Metallurgy
Extensively utilized in metallurgical plants, steel fabrication yards, and machining shops for moving, flipping, and staging heavy assemblies and raw materials.
