300 Tons Shipbuilding Gantry Crane

As a core piece of heavy lifting equipment in modern shipbuilding and offshore engineering, ที่ 300 tons shipbuilding gantry crane is specifically engineered to meet the rigorous demands of ship hull assembly, section hoisting, and offshore module handling. With its exceptional lifting capacity, stable operation, and versatile performance, this crane serves as the “backbone” of shipyards, dry docks, and large-scale marine structure manufacturing sites, significantly enhancing production efficiency and construction safety while adapting to the complex working environments of marine engineering.

ภาพรวมผลิตภัณฑ์

ที่ 300 tons shipbuilding gantry crane is a large-span, heavy-duty lifting device designed for outdoor and semi-outdoor operations, integrating advanced mechanical, ไฟฟ้า, and hydraulic technologies. Unlike traditional overhead cranes, it features a gantry frame supported by rigid and flexible legs, allowing it to move freely along ground rails and cover large working areas—making it ideal for hoisting heavy ship sections, แผ่นเหล็ก, and marine components with high precision. It is available in both single-girder and double-girder designs, with the single-girder option recommended for large spans and heavy loads due to its cost-effectiveness, while the double-girder design offers enhanced stability for complex lifting tasks.

300 Tons Shipbuilding Gantry Crane Core Technical Specifications

ที่ 300 tons shipbuilding gantry crane is customizable to meet diverse project requirements, with the following standard technical parameters (customizations available based on client needs):

Key Structural & Performance Advantages

1. แข็งแกร่ง & Durable Structure

The gantry frame is made of high-strength Q355B steel, After shot blasting and anti-corrosion painting (epoxy zinc-rich primer + topcoat) to resist salt spray, ความชื้น, and marine corrosion—extending the crane’s service life in harsh coastal environments. The frame adopts a variable cross-section optimization design to ensure structural strength while reducing overall weight, and the rigid-flexible leg combination prevents structural deformation during heavy-load operation and long-span movement.

2. ความแม่นยำสูง & ประสิทธิภาพ

Equipped with a frequency conversion control system, the crane achieves stepless speed regulation, ensuring smooth lifting, การลดลง, and movement without impact—protecting fragile ship sections and components from damage. The dual-trolley design allows for single lifting, double-hook ยก, and air flipping of ship sections, enabling seamless assembly of hull segments and significantly improving shipbuilding efficiency. A deviation rectification system can be equipped for extra-large spans to ensure stable movement of rigid and flexible legs, ป้องกันความเสียหายของโครงสร้าง.

3. การป้องกันความปลอดภัยที่ครอบคลุม

Safety is a top priority, with multiple protection devices to ensure operator and equipment safety: overload limiter, ตัวจำกัดความสูงในการยก, trolley travel limiter, crane travel limiter, wind speed and direction monitoring system, rail clamp device, and anchor device. The overload limiter automatically cuts off power when the load exceeds the rated capacity, while the wind speed monitoring system stops operation in strong winds (≥15m/s) to avoid accidents. All electrical components comply with international standards (เช่น, Schneider) เพื่อประสิทธิภาพที่เชื่อถือได้.

4. อเนกประสงค์ & ปรับแต่งได้

The crane is suitable for various shipbuilding scenarios, including dry dock operations, slipway construction, offshore platform assembly, and steel structure handling. It can be customized with different spans, lifting heights, and trolley configurations to meet the specific needs of small, medium, and large shipyards. Optional configurations include a 10t 360° rotating maintenance crane for convenient equipment maintenance, การควบคุมระยะไกลไร้สาย, and cabin control for flexible operation.

5. บำรุงรักษาง่าย & Low Operating Cost

ที่ เครนโครงสำหรับตั้งสิ่งของ is designed with maintenance in mind, featuring accessible components, centralized lubrication systems, and clear maintenance instructions. Routine maintenance is simple and cost-effective, reducing downtime and operational costs. The modular design allows for quick replacement of damaged parts, ensuring continuous operation of the shipbuilding line.
