PRODUCT INTRODUCTION
Four-link type portal crane has been extensively applied to loading and unloading at port and materiel handing at dockyard and metallurgy industry, The main structures are composed of steel frame, lifting mechanism, luffing mechanism, slewing mechanism, crane travel mechanism spreader device (grab,container spreader, and hook and electrmangnetdisk), electrical equipment and other necessary equipments for safety. Steel structures include jib and A-frame, slewing platform and gantry frame.
TECHNICAL DATA
APPLICATION
1. Container Handling at Ports & Intermodal Terminals
Loading and unloading ISO containers from trucks, trains, and vessels.
Stacking containers in storage yards with high precision using spreader attachments.
Handling empty and laden containers across multiple rows thanks to wide span capability.
2. Railway Freight Yards Transferring heavy cargo (steel coils, machinery, bulk goods) between railcars and ground storage. Servicing flatcars and specialized rail wagons with oversized loads. Enabling rapid turnaround of freight trains with high‑duty cycle operations.
3. Precast Concrete & Heavy Construction Lifting and positioning large precast concrete elements (beams, columns, panels, bridge segments) at manufacturing plants. Transporting heavy molds and formwork within precast yards. On‑site handling at infrastructure projects such as bridges, tunnels, and high‑rise buildings.
4. Steel Service Centers & Stockyards Moving steel coils, plates, pipes, and structural sections from storage racks to processing lines. Feeding shears, slitters, and laser cutters with heavy raw materials. Loading finished steel products onto flatbed trucks.
5. Heavy Machinery Manufacturing & Assembly Positioning large components (engine blocks, turbine housings, press frames) during assembly. Overturning and rotating heavy workpieces using auxiliary lifting beams. Servicing machining centers with heavy workpieces up to 100+ tons.
6. Wind Turbine & Renewable Energy Manufacturing Handling nacelles, hub assemblies, tower sections, and blades during fabrication. Assisting in assembly and testing of large‑scale wind turbine components. Loading finished components for transport to wind farms.

FEATURES
1
Enhanced Stability: The four-link structural design provides superior rigidity and anti-sway performance, ensuring precise load positioning even in windy outdoor environments.
2
Higher Lifting Capacity: Engineered for heavy loads, typically ranging from 10 tons to over 100 tons, making it ideal for heavy industrial and logistics applications.
3
Wider Span Capability: The four-link configuration allows for larger spans compared to conventional portal cranes, maximizing coverage in expansive work areas.
4
Improved Safety: The redundant structural design offers increased fail‑safe margins, reducing risks during high‑frequency or critical lifting operations.
5
Adaptability: Can be equipped with various lifting attachments (spreader bars, grabs, electromagnets) to handle containers, coils, plates, or bulk materials with ease.
