200 Grue à portique de construction navale de tonnes

Le 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.

Présentation du produit

Tailored for the harsh marine environment and complex shipbuilding processes, le 200 Tons Shipbuilding Gantry Crane integrates robust structural design, systèmes de contrôle précis, et une protection de sécurité complète. It is mainly used for hoisting, transporting, and overturning large hull segments (typiquement 120-180 tonnes), as well as auxiliary lifting tasks such as handling steel plates, barres d'acier, 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 & Avantages

1. Conception structurelle robuste

Adopting a double-box girder structure compliant with ISO 4301 normes, 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, humidité, and temperature changes in coastal shipyards, extending the service life and reducing long-term maintenance costs.

2. Précis & Système de contrôle efficace

Equipé d'un variateur de fréquence (VFD) système, 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, permettant aux opérateurs de choisir le moyen le plus pratique en fonction des conditions sur site, further improving work efficiency.

3. Protection de sécurité complète

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, dispositif de serrage de rail, anchor device, système de surveillance de la vitesse et de la direction du vent, 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, et autres dangers potentiels, protecting operators, équipement, and hull components throughout the operation process.

4. Polyvalent & Conception personnalisable

Le 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, hauteur de levage, 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.
