shipbuilding gantry crane (a type of MG double-girder gantry crane)
This is a shipbuilding gantry crane (a type of MG double-girder gantry crane). Its core information is as follows:
**Basic Attributes:** It is a heavy-duty lifting device, commonly used in shipbuilding and heavy industrial plants.
Technical Parameters:
| Lifting Capacity | Employs a multi-trolley combination (e.g., upper trolley + lower trolley) to adapt to the hoisting needs of different hull sections; Single-unit lifting capacity covers 50t~1000t (ultra-large models can reach 1600t). |
| Span | Standard models: 20m~80m; Ultra-large dock models: Maximum up to 229m (covering ultra-large dock operating areas) |
| Lifting Height | Standard models: 15m~51m; Ultra-large models: Maximum exceeding 90m (meeting the high-altitude assembly needs of ultra-large ships) |
| Working Class | Mainstream classes are A5 to A8 (suitable for heavy-load, high-frequency shipbuilding operations) |
| Operating Speed | Main trolley (movement of the entire machine): 2m/min~30m/min; Auxiliary trolley (movement on the main beam): 2m/min~25m/min; Lifting speed: 0.32m/min~10m/min (the heavier the load, the slower the speed). |
**Core Features:**
Structure: It adopts a gantry frame + double-girder design, equipped with multiple hooks (multiple slings and hooks are visible in the image). The legs are large steel structural components to ensure load-bearing stability.
**Core Advantages:** The core advantages of shipbuilding gantry cranes are tailored to the heavy-load, high-precision, and wide-range requirements of shipbuilding operations, specifically:
**Strong Heavy-Duty Adaptability:** Supports ultra-large lifting capacities (single unit up to 1600t), adopts a multi-trolley combination design, and can simultaneously/independently lift ship sections of different weights, adaptable to heavy component operations on ultra-large ships.
Wide operational coverage: Large span (maximum over 229m) + high lifting height (maximum over 90m) allows coverage of the entire dock area, enabling full-process hoisting of the hull from section to final assembly without the need for additional equipment transport.
High-precision operation capability: Equipped with low-speed micro-motion control (lifting speed as low as 0.32m/min), combined with a positioning system, it achieves millimeter-level alignment of components, meeting the high-precision assembly requirements of shipbuilding.
High operational efficiency: Multi-trolley collaborative operation mode can simultaneously complete the hoisting and relocation of different components, significantly reducing the interval between hull assembly processes.
Outstanding safety and reliability: Utilizing a high-rigidity steel structure + multiple safety protections (overload protection, limit protection, wind and anti-slip devices, etc.), it is suitable for the harsh outdoor, heavy-load, and high-frequency operating conditions of shipyards.
High degree of customization: Span, lifting capacity, lifting height, and other parameters can be customized according to dock size and ship tonnage, perfectly matching the specific shipyard's production process.
Labeling: The main beam of the equipment is marked with "Safety Production" and "Quality First," reflecting the safety and quality standards required for industrial equipment.
Main Applications: Primarily used for the hoisting, handling, and assembly of hull sections and large components in shipyards; it can also be extended to heavy cargo loading and unloading operations in large storage yards and heavy-duty factories.
