This case study covers Haitai Heavy Industry’s successful delivery of a custom‑built 400 ton shipbuilding gantry crane for Zonghai Ship Repairing & Building Co. Ltd. in Chizhou, Anhui Province. Facing rising ship‑block assembly workloads, the shipyard required high‑capacity lifting equipment for hull segment hoisting, transportation and aerial turnover. Henan Haitai Heavy Industry Co, Ltd. recently completed manufacturing, testing and official delivery of a 400‑ton shipbuilding gantry crane for Anhui Chizhou Zonghai Ship Repairing & Building Co. Ltd., bringing a robust lifting solution to support the yard’s medium‑large vessel construction project.
Haitai 400 Ton Shipbuilding Gantry Crane Project Overview
Modern shipbuilding heavily depends on reliable heavy‑duty lifting machinery to handle oversized hull blocks, modular transportation and precision docking work. As Chinese inland‑river and coastal shipyards expand production capacity, demand for high‑performance shipbuilding gantry cranes keeps growing.
Haitai Crane delivered a tailor‑made rubber‑tyred shipbuilding gantry crane adapted to riverside site wind and humidity conditions, completed factory testing, on‑site assembly and commissioning. After full load performance verification, the crane went into official operation, greatly improving the shipyard’s modular ship‑building efficiency, shortening production cycles and strengthening its capacity for medium‑to‑large vessel construction.
The Client’s Needs for Custom Shipbuilding Lifting Equipment Project
Anhui Chizhou Zonghai Ship Repairing & Building Co. Ltd. is a key local shipbuilder focusing on building inland waterway cargo vessels, engineering ships and partial offshore modules. With newly‑signed ship orders expanding, the shipyard encountered obvious bottlenecks in its production workflow. The original lifting setup could not fully satisfy frequent hoisting of heavy hull sections, aerial flipping and block‑closing operations. The project site sits along the Yangtze River, with changeable wind conditions and high ambient humidity.
The client put forward strict requirements:
- 400‑ton rated lifting capacity
- flexible cross‑yard mobility
- strong anti‑wind and anti‑corrosion performance
- stable multi‑hook synchronous control
- easy‑to‑maintain mechanical and electrical systems
More importantly, the whole machine needed to fit existing yard ground foundations without large‑scale reconstruction, to control overall project investment.
Haitai Crane’s Shipyard Gantry Crane Solution
Haitai Crane’s engineering team conducted thorough site surveys, analyzed local meteorological data and reviewed the shipyard’s production rhythm before finalizing the customized gantry crane solution. This 400‑ton shipbuilding gantry crane adopts heavy‑duty rubber‑tyred travelling design, removing the need for fixed rail laying, so the unit can freely travel across fabrication zones, storage areas and assembly berths. The box‑type main girder and portal leg structure passed finite‑element stress simulation to guarantee structural safety under full‑load and cross‑wind working status.
The whole machine is equipped with full‑frequency PLC control system, supporting independent single‑hook lifting and multi‑hook synchronized hoisting, realizing accurate aerial turnover and fine‑tuned positioning for large hull blocks. Special coastal‑grade anti‑corrosion paint is applied for humid riverside environments, while wind‑proof anchoring, rail‑clamping and real‑time load‑monitoring systems are equipped as standard safety configurations.
400 Ton Shipbuilding Gantry Crane Site Installation and Loads Test
Before shipment, the crane completed strict factory acceptance, including 1.25 times overload static load test and dynamic running test to verify every mechanical and electrical index. After components arrived at Chizhou site, HT Crane’s on‑site engineering team carried out segmented assembly, wiring, joint debugging and repeated functional testing. All safety protection mechanisms were checked item‑by‑item. The final on‑site acceptance test achieved all designed performance indicators, and the equipment was formally handed over to Zhonghai Shipbuilding for production operation.
Haitai Shipbuilding Gantry Crane Lifting Steel and Hull Segment in Anhui
Since commissioning, this Haitai 400‑ton shipbuilding gantry crane undertakes core tasks including heavy steel‑structure block lifting, cross‑site transfer and hull segment docking. It greatly cuts down block‑handling time, reduces auxiliary equipment input, and raises the whole ship‑building throughput. The client reports stable running performance, convenient operation and accessible daily maintenance. This delivery marks another practical successful project of Haitai Heavy Industry in the Yangtze‑river basin ship‑building market.

FAQs about HT Crane’s Shipyard Gantry Cranes
Q1: What working scenarios suit Haitai 400‑ton shipbuilding gantry crane?
A: It applies to hull block lifting, transportation, aerial turnover and block closing for medium‑large shipyards, also suitable for offshore module fabrication workshops.
Q2: Can the 400‑ton shipbuilding gantry crane work at windy riverside shipyards?
A: Yes. We add anti‑wind anchoring devices, wind speed alarm system and reinforced portal‑leg structure for riverside and coastal sites.
Q3: Do I need to lay special rails for rubber‑tyred shipbuilding gantry crane?
A: No. Rubber‑tyred travelling type runs on reinforced flat concrete ground, saving rail material and civil‑engineering cost. Rail‑mounted version is also optional.
Q4: Is customization available for span, lifting height and lifting capacity?
A: Fully customizable. We adjust span, lifting height, rated load and configurations based on your shipyard’s actual production demands.
Q5: What after‑sales support will Haitai provide after crane delivery?
A: Haitai offers on‑site installation guidance, commissioning, operator training, 12‑month warranty, remote technical diagnosis and spare‑parts supply services.
