Portal cranes are widely used in ports, docks, yards, and other locations to handle loading, unloading, and transshipment operations for ships and vehicles. Their design, manufacturing, and inspection comply with advanced domestic and international standards such as DIN, FEM, IEC, AWS, GB, as well as the latest national standards.
Based on the boom structure, portal cranes are categorized into two types: single-boom and four-link mechanisms.
The single-boom portal crane features a simple structure, high lifting capacity, and a lightweight design.
The four-link portal crane utilizes a combined boom system to achieve horizontal movement of cargo during luffing operations,characterized by minimal height variation, smooth luffing, and low power consumption.
Both types of portal cranes are capable of meeting the loading, unloading, and handling requirements for general cargo, bulk cargo, and containers, offering advantages such as broad applicability, high operational efficiency, and stable overall machine performance.

Q: Do you support customizing cranes according to my specific needs?
A: Absolutely. We offer full customization based on your workshop dimensions (span, lifting height), power supply specifications, duty cycle (FEM/ISO class), and special environmental requirements (explosion-proof, corrosion-resistant, high-temperature). Please provide your detailed operational requirements for a tailored design and quotation.
Q: Does the equipment comply with international safety and quality standards? What certifications do you have?
A: Yes. Our core design and manufacturing follow international standards such as ISO, FEM, DIN. We can apply for and provide CE certification (covering Machinery Directive MD and Low Voltage Directive LVD) for target markets, along with a full Declaration of Conformity and technical documentation.
Q: Does the price include installation, commissioning, and operator training?
A: Our standard quotation is typically EXW or FOB. However, we offer comprehensive value-added service packages, including remote installation guidance, optional on-site engineer commissioning services, and detailed installation manuals with operational training videos. Specific service terms are negotiable before order confirmation.
Q: How do you guarantee product quality? Do you have testing and factory inspection procedures?
A: We implement a strict quality control system. Every crane undergoes mandatory key process inspections, no-load and load tests(including rated load and overload tests), and complete operational debugging before leaving the factory. We welcome and support pre-shipment inspections by the buyer or third-party agencies (e.g., SGS).
Q: Can we visit your factory or see case studies of similar projects?
A: You are most welcome! We are delighted to arrange a visit to our manufacturing base to witness our production capability and quality control firsthand. We can also provide video case studies and references (under NDA) from our global clients with similar applications.
