YFM 5 Ton Telescopic Boom Marine Deck Crane with Personnel Lifting for LNG Vessels.
This YFM 5-Ton Telescopic Boom Marine Deck Crane is a compact lifting solution specially designed for LNG bunkering vessels, Offshore Supply Vessels (OSVs), and various special operation ships. Its standout advantage is the perfect integration of long-reach heavy-load lifting and safe man-riding operation within limited narrow deck space.
Core Specifications & Technical Performance Parameters
This telescopic boom marine deck crane:
- Main Hook Capacity: Rated lifting capacity 5 tons, working radius 4–29 m (for lifting heavy spare parts and bunkering hoses)
- Auxiliary Hook Capacity: Rated lifting capacity 2 tons, working radius 5.2–30.8 m (for routine precision lifting and material transportation)
- Man-Riding Operation Performance: Safe Working Load (SWL) 1 ton, safe operating radius 4–29 m (fully covers inspection, maintenance, and hoisting of key onboard areas such as LNG manifold assemblies)
- Boom Type: Fully hydraulic telescopic boom, effectively reducing deck footprint in stowed position

Core Engineering Advantages and Safety Configurations
1. Dual Braking System for Man-Riding Safety
For man-riding applications, we abandon conventional single-brake winches and adopt a redundant safety system consisting of dual built-in multi-disc caliper brakes plus external automatic band brakes. Combined with load-sensing control valves and anti-cavitation hydraulic locks, the winch can lock instantaneously under extreme conditions such as sudden power failure. Equipped with fall-arrest safety cables and man-riding baskets complying with DNV 2.7-1 standard, it minimizes risks during overhead working to the lowest level.
2. Space-Saving Compact Base Design for Tight Layouts
We fully understand that LNG vessels feature densely laid deck pipelines. The YFM engineering team optimized the base radius and slewing center, and adjusted the folding angle of the crane telescopic boom to the extreme limit. This allows the telescopic boom marine deck crane to fit perfectly into gaps between piping arrangements, without obstructing crew walkways or interfering with the original cryogenic pipelines and bunkering arm systems.

3. Heavy-Duty Marine Anti-Corrosion Coating System
To cope with coastal port environments featuring heavy salt spray and high humidity, YFM implements rigorous Sa2.5 grade sandblasting before delivery, paired with a heavy-duty anti-corrosion coating package: epoxy zinc-rich primer plus acrylic polyurethane topcoat. Photos of this deck crane undergoing continuous sea trials at the Port of Huelva prove that the coating remains intact and smooth with no rust formation, verifying reliable corrosion resistance under real offshore operating conditions.
4. Full-Range Safety Certifications and Stringent Testing
Prior to factory delivery, the telescopic boom crane undergoes no-load trial runs, 1.25 times static load tests, and 1.1 times dynamic load tests for main and auxiliary hooks in accordance with DNV ST-0377/0378 rules. For man-riding mode, it must pass a 1.5 times static load test and simulated emergency lowering test under power cut during man-lifting, with a static holding period of no less than 15 minutes.
