200 Tons Shipbuilding Gantry Crane

The 200 Tons Shipbuilding Gantry Crane is a heavy-duty, high-efficiency specialized lifting equipment meticulously designed for modern shipyards, dedicated to handling large-scale hull segments, engine modules, and prefabricated components in docks, berths, or slipways. As the backbone of mid-sized to large ship construction, this crane bridges the gap between basic heavy lifting and large-scale shipbuilding needs, enabling shipyards to efficiently complete hull assembly, section flipping, and component transportation, significantly enhancing production efficiency and expanding the scale of shipbuilding capabilities.

200 Tons Shipbuilding Gantry Crane

Product Overview

Tailored for the harsh marine environment and complex shipbuilding processes, the 200 Tons Shipbuilding Gantry Crane integrates robust structural design, precise control systems, and comprehensive safety protection. It is mainly used for hoisting, transporting, and overturning large hull segments (typically 120-180 tons), as well as auxiliary lifting tasks such as handling steel plates, steel bars, and outfitting equipment. With dual-trolley configuration as standard, it can achieve single-hook lifting, double-hook combined lifting, and aerial flipping of hull sections, meeting the diverse operational requirements of shipbuilding from block assembly to partial hull erection.

200 Tons Shipbuilding Gantry Crane Key Features & Advantages

1. Robust Structural Design

Adopting a double-box girder structure compliant with ISO 4301 standards, the crane ensures exceptional stability even when lifting uneven or off-center loads, with deflection controlled within 1/800 of the span under full load. The gantry frame consists of a rigid leg and a Y-shaped flexible leg (box-type structure for rigid leg, steel pipe structure for flexible leg) to reduce deadweight while enhancing structural strength and wind resistance. High-grade Q345B steel is used as the main material, combined with hot-dip galvanizing (≥80μm) and marine-grade protective paint, effectively resisting salt spray, humidity, and temperature changes in coastal shipyards, extending the service life and reducing long-term maintenance costs.

2. Precise & Efficient Control System

Equipped with a variable frequency drive (VFD) system, the crane achieves smooth starts and stops, avoiding sudden shocks to heavy loads and ensuring precise positioning of hull segments. Anti-sway technology reduces load swing by up to 70%, improving operational accuracy and reducing accident risks during high-altitude operations. The PLC-based automation system supports remote diagnostics, enabling early fault detection and scheduled maintenance to minimize downtime. Operation modes include cabin control and remote control, allowing operators to choose the most convenient way based on on-site conditions, further improving work efficiency.

3. Comprehensive Safety Protection

Safety is prioritized in the design, with a full set of safety devices to ensure reliable operation in heavy-duty environments. Key safety features include: lifting weight limiter system, rail clamp device, anchor device, wind speed and direction monitoring system, limit switches for all mechanisms, cabin safety interlock, and emergency stop buttons at multiple positions. These devices form a multi-layered safety barrier, effectively preventing overload, derailment, wind damage, and other potential hazards, protecting operators, equipment, and hull components throughout the operation process.

4. Versatile & Customizable Design

The 200 Tons Shipbuilding Gantry Crane is highly adaptable to different shipyard layouts and shipbuilding needs. It can be designed as single-girder or double-girder according to specific requirements, and the span, lifting height, and power supply can be fully customized. The dual-trolley configuration (upper trolley with two main hooks, lower trolley with one main hook and one auxiliary hook) enables flexible handling of long or irregular hull sections, including aerial flipping and precise alignment for welding and assembly. It is suitable for mid-sized shipyards producing medium to large vessels, including cargo ships, bulk carriers, and offshore vessels, providing flexible lifting solutions for various shipbuilding processes.
