Introduction of ME Shipbuilding Gantry Crane

Shipbuilding Gantry Crane is particularly suitable for the segmented transportation of large ship hulls and the turning operations of large ship bodies.

Features of ME Shipbuilding Gantry Crane

Product Highlights

• Capable of lifting extremely heavy loads with wide span and significant lifting height

• Compatible with single, double, and triple-hook lifting configurations

• Features two independent trolleys operating on separate rails, allowing the lower trolley to pass beneath the upper one

• Integrated side-shifting mechanisms enable precise positioning of ship sections

• Equipped with alignment correction technology to maintain straight travel and operational safety

Core Features

• Supports single or multi-hook operations for diverse tasks

• Enables in-air rotation and lateral shifting of ship sections

• Upper and lower trolleys operate without interference

• Suitable for simultaneous handling of single or multiple components

Robust Structural Design

• Trapezoidal main girder enhances load distribution

• Combines a straight (I-shaped) leg with an angled (A-shaped) leg for optimal stability

• Stairs or elevators inside the leg provide access to the cabin and main girder

• Available in single or double girder configurations

• Constructed with high-strength steel for extended durability

• Reinforced frame minimizes sway and improves operational stability

Safety and Reliability

• Wind resistance systems including clamps and anchors ensure secure operation

• Real-time monitoring tracks crane status during use

• Integrated safety systems: anti-collision sensors, wind speed alarms, and fire alerts

Energy-Saving Design

• Optional 10KV high-voltage power supply reduces energy usage

• Dual rails on one side help distribute wheel load and lower operational costs

Ease of Use and Maintenance

• High-precision automated positioning

• Maintenance-assisted jib crane mounted on the leg

• Pass-through trolley design supports complex lifting tasks

Key Specifications:

• Trapezoidal main girder with one rigid I-shaped leg and one flexible A-shaped leg; access via internal stairs or elevator

• Hoisting mechanism includes rope alignment to prevent slippage and ensure safe lifts

• Travel system features skew correction for automatic or manual deviation adjustment

• Intelligent control supports multi-hook synchronization with PLC and frequency control for millimeter-level accuracy

• Comprehensive safety systems: real-time monitoring, anti-collision, wind resistance, and fire alarms

Key Attributes:

Shipbuilding gantry cranes are specialized lifting systems designed for shipyards, capable of managing large ship segments with high load capacity, wide spans, and substantial height. Rated loads generally start at 100t and can reach 2500t, with spans extending beyond 40m—up to 230m—and lifting heights under the girder ranging from 40m to 100m.

To accommodate large spans, one leg is typically rigid (fixed) and the other flexible (hinge-connected). The main girder may be single or double. Depending on shipbuilding needs, these cranes support single, dual, or triple-hook operations, in-air rotation, and fine positioning—making them ideal for sectional assembly and turning tasks.

They commonly include upper and lower trolleys on separate tracks. The upper trolley houses two external hoists that function jointly or independently, supporting dual-hook lifting and rotation. Both hooks include traverse mechanisms for fine adjustments and rotational control. The lower trolley contains main and auxiliary hooks; the main hook works alone or jointly with the upper trolley’s hooks for triple-hook operations, while the auxiliary hook handles lighter loads.
