INTRODUCTION

A Shipbuilding Gantry Crane (commonly known as a Goliath Crane) is an ultra-heavy-duty gantry crane engineered specifically for ship hull assembly and block lifting on dry docks and slipways. Featuring massive spans and dual-trolley structures (upper and lower trolleys), it is designed to hoist, position, turn over ( $180$ hull block rotation), and align prefabricated steel vessel blocks weighing hundreds to thousands of tons with millimeter precision.

APPLICATION SCENARIO

[1] Hull Section Assembly – Lifting and mating prefabricated hull blocks in dry docks.

[2] Engine and Propeller Installation – Hoisting heavy marine engines, shafts, and propellers into position.

[3] Superstructure Fitting – Placing deckhouses, funnels, and masts onto the main hull.

[4] Block Turning – Using dual trolleys to rotate large hull sections for bottom welding.

[5] Launching Assistance – Cooperating with other cranes to slide a completed ship into water.

ADVANTAGES

[1] Ultra-High Capacity – Handles loads from 100t up to 1,200t+, essential for large vessels.

[2] Synchronized Lifting – Multi-trolley system allows precise control for lifting and turning heavy blocks.

[3] Long Span and High Lift – Wide span (>100m) covers entire dry dock; high lift height (>60m) accommodates tall ship sections.

[4] Marine Environment Durability – Corrosion-resistant coatings, sealed electricals, and anti-corrosion steel.

[5] High Duty Cycle – Designed for continuous, heavy-duty shipyard operations (A7-A8 duty class).
