Overview
ISO 24044:2020 - Ships and marine technology - Deck machinery - Multifunctional manipulator - defines classification, technical requirements, test methods, inspection rules and marking/packaging/shipping/storage for double‑folding multifunctional manipulators used in deck operations. It applies to design, manufacture and acceptance of manipulators for clamping and tidying anchor chain and ropes on ships.
Keywords: ISO 24044:2020, multifunctional manipulator, deck machinery, ships, anchor chain, rope clamping, SWL, test methods.
Key Topics
- Scope & Classification
- Applies to double‑folding multifunctional manipulators for anchor chain and rope handling.
- Structural types: fixed and travelling; configurations with multifunctional boom only or combined multifunctional boom and jib.
- Core Components & Parameters
- Main boom, multifunctional boom, jib, slewing tower body, multifunctional head (grip/clamp), fixed base or travelling mechanism.
- Basic parameters and product designation examples (e.g., HMF-3012-D).
- Clamping size ranges: anchor chain φ50–φ120 mm; rope φ50–φ84 mm.
- Safe working load (SWL) and lifting performance specified per model.
- Design & Material Requirements
- Environmental operation: sea state 4, ambient temperature −25 °C to 45 °C, high humidity with oil mist/salt spray.
- Steel wire rope: non‑rotating, nominal tensile strength 1 440–2 200 MPa.
- Structural treatments (weld stress relief), watertight slewing tower, specified pulley groove angles.
- Safety & Mechanical Systems
- Rotating hooks sized for SWL; slewing mechanisms with dual hydraulic drives, brakes, encoders and mechanical/electrical limits.
- Travelling mechanism details: roller trains, pinion and rack drive, speed control valves, buffers and lubrication provisions.
- Test Methods & Inspections
- Specified tests include no‑load, rated‑load, overload, safety protection checks, power‑supply fluctuation, insulation resistance, IP inspection for electrical cabinets and appearance quality.
- Marking, Packaging & Storage
- Nameplate and warning sign requirements, packaging and transport/storage rules.
Applications / Who Uses This Standard
- Shipbuilders and naval architects specifying deck machinery.
- Marine equipment manufacturers designing or producing multifunctional manipulators.
- Classification societies, shipowners, procurement and maintenance engineers performing acceptance and inspection.
- Safety and compliance teams ensuring machinery meets environmental, mechanical and electrical requirements.
