2.Telescopic Boom Aerial Work Platform Special for Shipyards: Dedicated Equipment for Ultra-Long Reach of Large Vessels
(1) Advantages of Core Structure and Technical Parameters
The telescopic boom aerial vehicle adopts single-section / multi-section synchronous rigid telescopic booms without redundant hinge joints, delivering high overall boom rigidity and extremely small shaking amplitude during high-altitude operation. The maximum working height covers 20-43 meters, the maximum horizontal outreach exceeds 23 meters, and the rated load capacity is 250kg. The platform can hold 1 to 2 construction workers together with heavy equipment such as welding machines, flaw detectors and high-pressure spraying rigs. The chassis can climb gradients up to 30%, adapting to ramps in drydocks and road surfaces with height differences between hull blocks. Factory-matched wear-resistant solid tires exclusive for shipyards resist welding slag and steel plate abrasion, greatly extending chassis service life. Targeting salt fog working conditions at docks, all hydraulic pipelines and electrical cabinets of the whole machine adopt full-sealing anti-corrosion treatment with thickened anti-rust coatings on the surface, suitable for long-term open-air outdoor construction.
(2 )Applicable Vessel Types and Core Construction Scenarios
Telescopic boom aerial vehicles focus on high-height, long-span and long-distance outdoor high-altitude operations, serving as the preferred equipment for large LNG carriers, ultra-large container ships, offshore crane vessels and large river-sea oil tankers. Full-process construction of outer plates of LNG carriers: 271,000 m³ and 174,000 m³ LNG carriers are nearly 300 meters in length with extremely large continuous curved spans on the side hull, which cannot be fully covered by scaffolding. The telescopic vehicle moves smoothly along the drydock ground, and its boom stretches horizontally to blind zones at midship, bow and stern to complete flaw detection on outer surfaces of cargo tanks, anti-corrosion treatment of cryogenic pipelines and large-area hull spraying, tripling construction efficiency per vessel. Super-high-rise steel structure assembly on superstructures: Welding, fireproof cladding and railing installation on outer sides of 4 and 5-deck superstructures of large vessels, with working heights exceeding 30 meters. The ultra-long boom of the telescopic vehicle does not need to dock close to the hull to avoid scratch damage to hull steel plates.
3.Articulated Boom Aerial Work Platform Special for Shipyards: Dedicated Equipment for Complex Obstacle and Narrow Multi-Deck Working Conditions
(1) Advantages of Core Structure and Technical Parameters
The articulated boom vehicle adopts a multi-section hinged folding boom design with multi-joint 3D flexible steering capacity to realize "obstacle-surpassing operation", passing through deck uprights, steel supports and hull block frames to reach hidden construction points. The working height ranges from 12 to 30 meters, and the combined multi-section articulated boom can flexibly adjust spatial posture for smooth passage through narrow block workshops and multi-deck interlayers of vessels. The whole machine features a compact body and small turning radius, easily navigating narrow passages inside blocks and gaps between two decks of vessels. The hydraulic system is equipped with impact-resistant buffering and multi-joint synchronous linkage control; slight fine-tuning enables precise alignment with weld seams and pipeline points. It is also fitted with anti-corrosion chassis and tear-resistant wear tires for shipyards, operating stably under variable temperature, salt fog and welding slag conditions. The rated load capacity ranges from 230kg to 320kg, meeting the demand for two operators to work simultaneously with small maintenance tools.
(2)Applicable Vessel Types and Core Construction Scenarios
Articulated boom aerial vehicles target complex mid-low-altitude spaces full of interlayers and obstacles, suitable for medium and small methanol carriers, inland container ships, product tankers and auxiliary engineering vessels.
Inspection of vessel interlayers and outer double-bottom surfaces: Scaffolding cannot be erected in interlayers between double hulls and areas shielded by deck crossbeams; the folding articulated boom bypasses steel structures to complete weld grinding and anti-corrosion touch-up.
Outer construction of multi-layer corridors on superstructures: Multi-layer wheelhouses and equipment platforms overlap with dense uprights and pipelines; multi-joint bending of the articulated boom accurately reaches construction points on outer walls of each deck.
High-altitude operation inside block workshops: Steel frames and tool supports are densely arranged in hull block storage areas. The small turning radius of the articulated boom allows flexible transit inside the workshop, eliminating large-scale site clearance for welding and primer spraying on outer surfaces of blocks.
Maintenance of small LNG bunkering vessels and inland fuel tanks: Small-sized hulls with densely arranged equipment and pipelines; the articulated boom shuttles through equipment gaps to complete fireproof cladding and pipeline inspection on outer surfaces of tanks.
(3)Customized Adaptation Solutions for Shipyards
Custom narrow-chassis version for narrow block workshops; fully electric silent model for operation inside closed cabins without exhaust accumulation; optional anti-collision induction device that automatically decelerates when approaching hull steel plates to prevent scratch damage to vessel paint during construction.
4.Combined Use of Articulated and Telescopic Booms: Quantifiable Comprehensive Benefits for Shipyards
(1)Greatly Shortened Drydock Construction Cycle
Compared with traditional scaffolding construction mode, the combined telescopic and articulated boom equipment can start construction upon entry without the full process of erecting, dismantling and transporting steel pipes. Taking a 174,000 m³ LNG carrier as an example, the comprehensive construction period for outer plate flaw detection and superstructure high-altitude procedures is shortened from 12-15 days to 3-4 days, reducing single-vessel drydock occupancy time by 10%~18%. Annual vessel delivery volume of shipyards is significantly improved under identical dock resources. After purchasing hundreds of telescopic and articulated boom vehicles in bulk, Dalian Hengli Shipyard raised block turnover efficiency by 22% and achieved remarkable growth in annual shipbuilding capacity.
(2)Long-Term Sharp Reduction in Comprehensive Operating Costs
Labor downsizing: A single boom vehicle only requires 1 operator to replace a scaffolding team of 6-8 personnel, offsetting year-on-year rising labor costs for high-altitude work.
Zero consumable expenses: No continuous procurement of steel pipes, couplers and anti-slip planks, eliminating warehousing, transportation and maintenance costs for consumables.
Reduced rework: Boom vehicles cover all weld and anti-corrosion areas without construction blind spots, eliminating rework costs caused by missed inspections.
Reusable equipment: One telescopic or articulated boom vehicle can be recycled for construction of dozens of vessels, generating benefits for many years from one-time procurement.
(3)Full Compliance with CCS Safety and Environmental Protection Requirements
Compliant safety hardware: The full series is equipped with overload protection, emergency manual descent, 1.1m heightened safety guardrails and anti-squeeze induction devices, reducing high-altitude fall risks at the source and meeting the mandatory national standard CB 4286-2013 for vessel high-altitude operation safety.
Explosion-proof compliance: Custom electric explosion-proof models meet construction requirements for Zone 1 hazardous compartments of LNG and methanol vessels. Spark-free power systems eliminate ignition hazards and pass drydock equipment inspection by China Classification Society (CCS).
Green and low-carbon: Fully electric models produce zero exhaust and low noise without gas accumulation in closed cabins, complying with IMO low-carbon shipping control and green shipbuilding standards for shipyards.
(4)Salt Fog Corrosion Adaptability
The whole machine adopts fully sealed hydraulic and electrical systems with thickened anti-rust coatings, delivering far lower failure rates than general industrial aerial lifts during year-round operation at coastal shipyards and cutting downtime and maintenance losses.
5.Market Development Trends for Domestic and Overseas Shipyards
(1)Continuous Surge in Demand for Explosion-Proof Electric Boom Vehicles
With the implementation of global IMO greenhouse gas emission reduction and shipping fuel substitution policies, orders for LNG and methanol dual-fuel vessels rise year by year, accompanied by growing Zone 1 explosion-proof construction areas. Domestic large shipyards as well as repair yards in Europe and Southeast Asia all prioritize fully electric explosion-proof articulated and telescopic boom vehicles during procurement, while the procurement proportion of traditional fuel-powered boom vehicles keeps declining.
(2)Segmented Procurement Becomes Mainstream
Large ocean-going LNG and container shipyards purchase high-reach telescopic boom vehicles in bulk to satisfy ultra-long hull outdoor high-altitude construction; inland shipyards and medium-small repair yards and bunkering vessel manufacturers take mid-height articulated boom vehicles as core procurement products; leading comprehensive shipyards purchase both types in combination to cover all indoor and outdoor high-altitude working conditions.
(3)Premium Price for Custom Anti-Corrosion and Wear-Resistant Shipyard-Specific Models
General engineering boom vehicles lack salt fog protection on chassis and pipelines, prone to rust and leakage failures after half a year of dockside use. Custom articulated and telescopic boom vehicles with full heavy anti-corrosion, shipyard wear-resistant tires and anti-welding slag protection gain growing market recognition; overseas shipowners prioritize checking shipyard-adapted configurations during procurement.
(4)Intelligent Boom Vehicles Gradually Become Standard Equipment for High-End Shipyards
New-generation articulated and telescopic boom vehicles integrate fault self-diagnosis, remote power monitoring and intelligent limit control systems. Equipment management departments of shipyards realize unified online operation and scheduling, matching the general trend of digital and intelligent upgrading in shipbuilding. Intelligent boom aerial equipment is specified for construction of high-end new energy vessels.
