MQ portal cranes are widely deployed at ports, railway stations and cargo storage yards to perform efficient loading, unloading and cargo transshipment tasks, effectively accelerating ship and vehicle turnover efficiency. This series of portal cranes integrates compact structural layout, stable travelling performance, high working efficiency and elegant appearance. Featuring comfortable operation, reliable safety performance and convenient daily maintenance, the crane is well-suited for space-limited port working areas. It reserves sufficient passage space for vehicle traffic during ship cargo handling, making it an ideal universal handling solution for general-purpose ports.
Single-Arm Portal Crane
The single-arm portal crane is mainly applied for bulk cargo handling at medium and small-sized ports. With lightweight structure and low wheel pressure, it greatly reduces foundation investment and brings significant economic benefits. The crane adopts either rack luffing or wire rope pulley luffing mechanism to realize loaded variable amplitude adjustment, free horizontal displacement and 360-degree rotary lifting. Coordinated luffing movements ensure smooth and highly efficient operation. The equipment supports flexible configuration with standard hooks and bulk material grabs to adapt to diverse cargo handling demands.
Four-Bar Combined Portal Crane
The four-bar combined portal crane is a mobile full-slewing portal crane with optimized four-linkage structure. It achieves perfect mechanical balance between lifting arms and counterweights. Two portal frame structures are available: cylindrical type and four-leg type. This versatile portal crane is primarily used for container handling and can be equipped with hooks or grabs to handle various cargo types.
1. Supports dual spreader configurations including hooks and grabs, delivering strong adaptability and wide application coverage for diversified cargo types.
2. Optimized four-bar linkage mechanism ensures precise and stable luffing operation with high positioning accuracy.
3. Enables 360° full-range slewing, greatly expanding the effective working coverage.
4. Adopts PLC intelligent control and AC variable frequency speed regulation system, ensuring stable, smooth and reliable full-process operation.
5. Customizable wireless remote control system is available to meet unmanned and flexible operation requirements.
6. Equipped with comprehensive safety protection devices, supporting operational communication and auxiliary lighting systems to guarantee safe and continuous port operation.
