Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Quay Cranes. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This rail-mounted container gantry crane is designed for container-handling operations in ports, intermodal terminals, railway freight yards, and container yards. The listed configuration uses a double box girder structure, an electric trolley or winch lifting system, and rail-mounted crane travelling equipment.
Published configuration data includes rated load capacities of 30–70 t, lifting heights of 12.3–21 m, and spans of 18–40 m. Other fields in the supplied product data list capacity, height, and span ranges of 5–50 t, 12–60 m, and 20–80 m respectively.
Because these ranges differ, buyers should treat them as configuration-dependent and obtain a project-specific technical schedule before ordering. The listed operating data includes lifting speeds of 13–40 m/min, crane travelling speeds of 42–50 m/min, and trolley travelling speeds up to 70 m/min.
Work classifications are shown as A6–A8 in the detailed description and A5–A7 elsewhere in the listing. Available operating approaches are described as manual, semi-automatic, automated, and remote operation, while another field identifies ground control plus customized cabin control.
The standard power entry is three-phase 380 V, 50 Hz, with customized electrical supply available. Structural steel, steel plate, rectangular tube, and carbon steel are identified as construction materials. Listed safety provisions include a high-wind alarm, dynamic safety scanning, and anti-sway technology.
The stated operating-temperature range is -20°C to 40°C. Customization is available, and the stated warranty period is one year.
Procurement questions to confirm: Request a single reconciled specification covering rated capacity, lifting height, span, duty class, lifting and travelling speeds, maximum wheel load, total crane weight, control mode, power supply, and rail interface.
Confirm whether the intended duty is container handling or another lifting process, and define the required lifting attachment. Ask for the exact scope and settings of the anti-sway, wind-alarm, and scanning systems.
Buyers should also verify the applicable certification package, site conditions, civil and rail requirements, electrical interfaces, inspection and acceptance procedure, shipping split, installation scope, commissioning, operator training, spare parts, maintenance support, and warranty exclusions before contract approval.
