Professional solutions for concrete precast equipment, mould systems, and metallurgical processing machinery.
Our portal slewing crane is a heavy-duty lifting machine specially designed for ports, docks, freight yards and construction sites. It is widely used for bulk cargo handling, general cargo lifting, container operations and heavy component transfer, featuring large operating radius, wide slewing range, stable performance and high efficiency, making it essential equipment for modern port logistics and engineering projects.
Made of high-strength steel with professional anti-corrosion treatment, the crane is durable and adaptable to coastal high-humidity and high-salt spray environments. Equipped with a variable frequency control system, it runs smoothly with low impact. Multiple safety devices including overload protection, limit protection and emergency brake ensure safe operation in line with international standards.
The crane supports 360° continuous rotation with flexible operation and small blind spots. Adopting a modular design, it is easy to install and maintain with highly interchangeable parts. We provide customization on lifting capacity, working range and control system to meet different overseas working conditions. Our products are exported worldwide with reliable quality and trusted by international customers.
