How To Choose The Right Boom Lift For Shipyard Work？

  Shipyard aerial work is far more complex than ordinary building construction. Vessel hull curves, dense steel structures, narrow deck gaps, salt-fog corrosion, and uneven dock ground put forward extremely strict requirements for boom lifts. Choosing a mismatched aerial platform will lead to low construction efficiency, frequent equipment failures, and even potential safety hazards.

This complete guide explains the core selection factors for shipyard boom lifts, helping shipyards and engineering contractors pick cost-effective, durable, and site-adaptive lifting equipment for new ship construction, hull spraying, welding polishing, and vessel maintenance.

Before selecting a boom lift, it is necessary to clarify the exclusive difficulties of shipyard operations, which are the core basis for model selection:

Complex obstacle environment: Superstructure columns, hull segmented frames, and dense pipeline layouts block straight lifting paths, making conventional straight boom lifts inaccessible to hidden working points.

Variable working heights and spans: Large container ships, LNG carriers, and oil tankers require ultra-long horizontal outreach and super-high working height coverage.

Harsh corrosive environment: Dock salt fog, welding sparks, and grinding scraps easily damage ordinary hydraulic pipelines and electrical systems.

Unstable ground conditions: Dry dock ramps, segmented height differences, and steel plate ground require strong off-road and climbing performance.

Heavy-load tool operation: Workers need to carry welding machines, flaw detectors, and high-pressure spray guns, putting forward higher requirements for platform load capacity.

The biggest confusion for shipyard procurement is choosing between articulating boom lift and telescopic boom lift. The two models correspond to completely different shipbuilding scenarios:

Articulating Boom Lift (Best for Complex & Narrow Shipyard Work)

The multi-joint folding boom realizes unique up-and-over obstacle operation. It can bypass steel structures, deck railings, and hull partitions to reach blind working areas that straight booms cannot access.

Best application scenarios:

Multi-layer superstructure outer wall welding and fireproof coating

Hull interlayer, double-bottom gap, and narrow segmented workshop operation

Medium and low-altitude obstacle-intensive maintenance work

Telescopic Boom Lift (Best for Super-High & Long-Span Vessel Operation)

The rigid synchronous telescopic boom features low shaking amplitude and ultra-long horizontal outreach, suitable for large-area and long-distance continuous operation with no obstacles.

Best application scenarios:

Full outer hull spraying and anti-corrosion treatment of LNG carriers and ultra-large container ships

Super-high deck steel structure assembly and large-area flaw detection

Long-distance horizontal operation along the dry dock

Parameter matching directly determines construction efficiency and safety. Shipyard equipment cannot blindly pursue high parameters; it needs precise matching based on vessel types and working areas.

Working Height & Horizontal Outreach

For ordinary cargo ships and small engineering vessels: select 14–24m working height;

For large container ships and LNG carriers: prioritize 28–43m super-high models with maximum horizontal outreach of 23m+, covering full hull side span operation.

Load Capacity

Shipyard operations require carrying personnel + heavy tools. The rated load must reach 250kg–320kg to support 2 workers and welding, spraying, and testing equipment at the same time.

Gradeability & Chassis Performance

Dry dock ramps and uneven steel ground require a minimum 30% gradeability. Equipped with shipyard-specific solid wear-resistant tires to prevent welding spark burnout and steel plate abrasion.

Ordinary construction boom lifts are not adapted to shipyard harsh environments. Professional ship-specific configurations are essential for long-term stable operation:

Full anti-corrosion treatment: Thickened anti-rust coating for the whole machine, fully sealed electrical cabinets and hydraulic pipelines to resist dock salt fog erosion.

Built-in boom wiring design: Hydraulic hoses and cables are hidden inside the boom to avoid damage from welding sparks and polishing debris.

Complete safety protection: Real-time tilt monitoring, overload protection, emergency lowering system, and anti-collision limit switches to adapt to complex wind conditions at the dock.

360° continuous rotation: No need to move the whole machine frequently, solving the problem of limited driving space between hull segments.

Diesel boom lift: Strong power, free of site power supply restrictions, suitable for outdoor dry dock large-area hull construction and all-weather heavy-duty operation.

Electric boom lift: Zero emission, low noise, suitable for indoor segmented workshops and enclosed hull inner operation, compliant with shipyard environmental protection standards.

Quanjin Heavy-Industry optimizes complete-machine configurations for harsh shipyard working conditions. Its product lineup including SP150A, ST200C, STJ220C, ST260C, ST280N, ST340N and STJ380N covers working heights from 15 to 43 meters, suitable for various ship construction and repair projects. Equipped with Korean-origin hydraulic technology, the machines deliver stable operation with minimal jitter at height. Enhanced anti-corrosion, wear-resistant and spark-proof performance enables them to cope with salt spray, welding slag and high-intensity continuous operations.
