Industry Background and Problem Definition
Large shipyards and offshore engineering sites are typical complex industrial environments. Operations such as hull exterior rust removal, section painting, ship-side welding and offshore platform structure maintenance are often performed at heights from 20 m to over 40 m. Work surfaces may be curved, inclined, segmented or blocked by multi-layer steel structures.
Traditional scaffolding and ordinary aerial access equipment often cannot balance access efficiency, load capacity and safety stability. Scaffolding requires long erection and dismantling cycles, occupies valuable yard space and is slow to relocate. Conventional straight boom equipment may fail to approach the work surface when ship sides, pipelines, steel plates, welding equipment or temporary pits block the access route.
Access Blockage
Curved hull profiles, ship-side edges, pipelines and temporary structures can prevent workers from reaching the exact operating point.
Heavy Tool Payload
Sandblasting guns, welding machines, cables, coating materials and safety tools increase platform load requirements.
Coastal Stability Risk
Wind exposure and elevated extension place higher requirements on boom rigidity, chassis stability and rotation control.
Core Solution Logic
The essential requirement of shipyard and offshore high-access maintenance is not only to lift workers to height. It is to position workers, tools and materials safely, stably and precisely near the work surface despite obstacles, heavy loads and frequent work-position changes.
Onchtech builds the solution around heavy-duty diesel self-propelled telescopic boom lifts and articulating boom lifts. Articulating boom lifts are suitable for crossing ship sides, pipelines and temporary structures, while telescopic boom lifts are suitable for high elevation, long horizontal outreach and direct access to large hull or offshore structure surfaces. The integrated selection logic covers six factors: height, outreach, obstacle crossing, payload, stability and site mobility.
Key Capability Modules
1. High-Reach Access
Work heights around the 40 m class support hull exterior work, ship-side construction, ship section maintenance and offshore platform component access. This reduces time spent repeatedly erecting and dismantling scaffolding across scattered work points.
2. Obstacle-Crossing Reach
Articulating boom lift models can move upward and outward around pipelines, steel plate stacks, temporary pits, ship-side edges and structural barriers. The SAL-38J provides a maximum up-and-over height of 19.5 m for demanding marine access conditions.
3. Heavy-Load Work Platform
Dual-load platform configurations support workers and maintenance tools together. Telescopic boom models can provide 300 kg / 460 kg capacity, while articulating boom models can provide 230 kg / 480 kg capacity, helping reduce interruptions caused by limited payload.
4. Stable Elevated Operation
Rigid boom structures, heavy-duty chassis design and controlled rotation systems help improve stability during rust removal, grinding, coating and welding tasks where platform vibration can affect work quality and operator confidence.
5. Rough-Terrain Yard Mobility
4WD, 4WS and rough-terrain tire configurations improve equipment movement across shipyard ground conditions such as steel plates, cables, ramps, welding zones and temporary construction areas.
6. Manufacturing and Delivery Support
Hunan Hongchang Machinery Co., Ltd. supports complete machine manufacturing, attachments, structural components and OEM/ODM/OBM cooperation. The company holds CE, ISO 9001 and UDEM certifications and serves customers in more than 20 countries and regions.
Application Scenarios
Hull Exterior Rust Removal
For large curved hull surfaces, articulating boom lifts help workers bypass ship-side and ground obstacles while carrying blasting or grinding tools close to the rust removal surface.
Ship Section Coating and Painting
Heavy-load platforms support workers, hoses, coating materials and auxiliary tools, helping maintain continuous spraying coverage across large structure areas.
Ship-Side Welding and Inspection
Stable boom structures and heavy-duty chassis support more controlled elevated positioning for welding, inspection, grinding and repair tasks in wind-exposed coastal environments.
Offshore Structure Installation and Repair
A combined configuration of telescopic and articulating boom lifts can cover different heights, outreach distances and access angles for offshore platforms, large modules and steel structures.
Recommended Equipment and Key Parameters
For high-difficulty shipyard access, Onchtech recommends matching equipment by access route, working height, horizontal outreach, platform load and ground conditions rather than selecting by height alone.

Operational Value for B2B Customers
- Higher work efficiency: reduces dependence on scaffold erection, dismantling and repeated repositioning during hull rust removal, painting, welding and repair.
- Improved access capability: combines articulating obstacle-crossing reach and telescopic long horizontal outreach to address complex hull contours and blocked approach paths.
- Better payload adaptability: dual-load platform options support workers, heavy tools and auxiliary materials, reducing the need for split operations caused by insufficient load capacity.
- More stable elevated work: rigid boom structures, heavy-duty chassis, 4WD/4WS mobility and controlled rotation design help reduce work interruption and elevated-position risk.
- Lower comprehensive operating burden: mechanical high-access work can replace part of scaffold-dependent and manual relocation processes, helping control waiting time, setup cost and repetitive labor.
