Product Description
Marine Deck Crane
Marine deck crane, Knuckle boom crane is a kind of special purpose crane to carry out transportation operations in the maritime environment. They are mainly used for the transportation of goods between ships, the supply of sea, the delivery and recycling of object during underwater operations.
The hydraulic system of Zehua deck crane innovatively adopts a closed system instead of the open system, solving the problem of the lifting brake control, which is rare to see for deck cranes. After successfully applying the closed system of the deck crane, the hydraulic oil consumption has been reduced by more than half compared to the open system deck cranes, and the power consumption has also been greatly reduced. This is a major breakthrough in energy saving and environmental protection. This crane has obtain 6 national patents.
Zehua deck crane is designed for such condition and can be customized as per our clients' variable working requirements.

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.
