Product Details and Features

The semi-gantry crane adopts a cantilever lifting beam structure, with one side supported on the ground and the other side suspended from the girder. This design makes the semi-gantry crane flexible and adaptable to a variety of job sites and conditions.

Semi-gantry cranes are highly customizable and can be designed and manufactured to suit specific needs. It can be customized based on workload, span and height requirements to meet the needs of different applications.

Semi-gantry cranes have a smaller footprint and are suitable for operations in limited spaces. One side of its bracket is directly supported on the ground without additional support structures, so it takes up less space.

Semi-gantry cranes have lower construction costs and faster erection times. Compared with full gantry cranes, semi-gantry cranes have a simpler structure and are easier to install, so they can significantly reduce construction costs and installation time.

Application

Ports and Harbors: Semi gantry cranes are commonly found in ports and harbors for cargo handling operations. They are used to load and unload shipping containers from vessels and transport them within the port area. Semi gantry cranes offer flexibility and maneuverability in handling containers of different sizes and weights.

Heavy Industry: Industries such as steel, mining, and energy often require the use of semi gantry cranes for lifting and moving heavy equipment, machinery, and raw materials. They are essential for tasks like loading/unloading trucks, relocating large components, and assisting in maintenance activities.

Automotive Industry: Semi gantry cranes are utilized in automobile manufacturing plants for lifting and positioning car bodies, engines, and other heavy vehicle components. They aid in assembly line operations and facilitate efficient movement of materials across different stages of production.

Waste Management: Semi gantry cranes are employed in waste management facilities to handle and transport bulky waste items. They are used to load waste containers onto trucks, move waste materials within the facility, and assist in recycling and disposal processes.

Product Process

Design: The process begins with the design phase, where engineers and designers develop the specifications and layout of the semi gantry crane. This includes determining the lifting capacity, span, height, control system, and other required features based on the customer’s needs and the intended application.

Fabrication of Components: Once the design is finalized, the fabrication of various components begins. This involves cutting, shaping, and welding steel or metal plates to create the main structural components, such as the gantry beam, legs, and crossbeam. Components like hoists, trolleys, electrical panels, and control systems are also fabricated during this stage.

Surface Treatment: After fabrication, the components undergo surface treatment processes to enhance their durability and protection against corrosion. This may include processes like shot blasting, priming, and painting.

Assembly: In the assembly stage, the fabricated components are brought together and assembled to form the semi gantry crane. The gantry beam is connected to the legs, and the crossbeam is attached. The hoist and trolley mechanisms are installed, along with the electrical systems, control panels, and safety devices. The assembly process may involve welding, bolting, and aligning the components to ensure proper fit and functionality.
