100-Ton Boat Lift Hoist Crane for a Commercial Shipyard in Vung Tau, Vietnam

100-TON BOAT LIFT HOIST CRANE FOR A COMMERCIAL SHIPYARD IN VUNG TAU, VIETNAM

Background

1.A shipyard on the Thi Vai River in Vung Tau, Vietnam, services offshore support vessels, coastal cargo ships, and fishing fleets.

2.An aging fixed rail-mounted lift restricted operations to a single slipway, creating bottlenecks during peak maintenance periods.

3.The operator needed a mobile boat lift hoist crane capable of hauling vessels up to 100 tonnes across multiple docks.

4.The yard opted for a self-propelled marine travel lift to replace the fixed system.

The Challenge

1.Constrained Site: The shipyard operates on a narrow strip between the river and a service road, demanding Ackermann steering and multi-directional travel for tight manoeuvring.

2.Diverse Vessel Profiles: The yard services highly variable vessels — from 20-tonne fishing boats to 95-tonne offshore supply vessels with broad beams — requiring tool-free sling reconfiguration between lifts.

3.Corrosive Marine Environment: Year-round humidity, salt-laden air, and monsoon conditions meant the crane needed a proven marine-grade epoxy anti-corrosion coating and sealed electrical enclosures.

The Solution

1.The shipyard selected a Yuntian 100-tonne Boat Lift Hoist Crane — a self-propelled rubber-tyred mobile gantry with a 12.5-metre span and diesel-hydraulic drive.

2.Twelve steering modes, including crab travel and 90-degree pivot rotation, enable tight-radius movement.

3.Adjustable multi-point soft slings distribute hull pressure evenly, with crews able to reconfigure setups in approximately fifteen minutes.

4.A VFD control system delivers stepless speed regulation for precise keel-block positioning.

5.IP56-rated enclosures and chrome-plated hydraulic rods protect against the coastal environment.

6.A wireless remote control allows the operator to maintain direct sight of the sling crew during lifts.

7.Our service and support team delivered on-site commissioning and a five-day operator training programme, with the full project documented in our case studies collection.

Key Advantages

1.Compact gantry with Ackermann steering and 90-degree pivot for confined quay operations.

2.Tool-free soft sling reconfiguration enabling fast vessel changeover.

3.VFD control for precise positioning and safe ground-crew coordination.

4.Marine-grade corrosion protection and IP56 enclosures for tropical coastal conditions.
