A telescopic offshore marine deck crane is a type of lifting equipment that is specially designed for offshore operations. Telescopic offshore marine cranes allow you to have a longer reach on board. Being able to retract the telescopic boom with an external telescopic gearbox makes it easier for you to store it on the deck of your vessel, creating more space on deck. Using a high-performance telescopic boom marine crane allows you to work more efficiently without compromising the space of the offshore supply vessel.
Specification
Applications
1. Loading and Unloading of Supplies for Offshore and Inland Water Vessels
Dry Cargo Ships: Lifting containers, bagged goods, and barreled chemicals. The 40-meter boom can cover long-distance loading and unloading between the wharf and the deck, especially suitable for small wharves without shore cranes.
Auxiliary for Liquid Cargo Ships: Hoisting oil delivery hoses, metering equipment, or transferring pump bodies, valves, and other components during maintenance.
Supplying Engineering Vessels: Providing fuel and spare parts for dredgers and ships.
2. Auxiliary Operations in Marine Engineering
Construction of Small Offshore Platforms: Lifting steel structure components of platforms and auxiliary drilling equipment.
Submarine Pipeline Laying: Hoisting pipeline docking tools and launching/recovering underwater robots (ROVs). The 40-meter boom can extend beyond the ship's side to reduce the distance from the hull during operations.
Auxiliary for Wind Power Installation: Lifting grouting equipment and cable protection pipes for small offshore wind power pile foundations.
3. Shipbuilding, Repair, and Maintenance
Hoisting in Shipyards: In the construction of medium and small-sized ships, lifting main engine components (such as crankshafts and cylinder blocks, with some light main engine components weighing ≤ 30 tons), rudders, and propellers.
On-Voyage Maintenance: This includes replacing anchor chains for ships during navigation and hoisting lifeboats. The telescopic boom can adjust the operating angle when the hull is shaking.
4. Fishery and Special Operations
Supplying Ocean-Going Fishing Vessels: Hoisting fishing nets, refrigeration equipment, and fish catch transfer boxes. The 40-meter boom enables cross-ship lifting between mother ships and fishing boats.
Deploying Equipment for Research Vessels: Hoisting deep submersibles, trawling equipment, and meteorological observation instruments for marine research vessels.
5. Emergency and Rescue Missions
Maritime Search and Rescue: Hoisting survivor transfer baskets from wrecked ships and salvaging small wrecked boats and rafts.
Oil Spill Treatment: Lifting oil booms, skimmers, and other anti-pollution equipment to deploy operational equipment in oil spill areas quickly.
Key Configurations
Lifting System1. 4-5 sections of high-strength steel telescopic boom (maximum length 40 meters), hydraulically driven for extension and retraction;2. Main and auxiliary double winches (single rope pulling force ≥ 35 tons), equipped with anti-corrosion steel wire ropes;3. 360° full-slewing mechanism with self-locking brake.
Control and Safety1. Linked operating console + PLC intelligent control (anti-overloading);2. Load moment limiter, dual braking, emergency stop mechanism;3. Optional wireless remote control (50-meter range).
Power and Protection1. Marine power supply / independent generator set (≥ 150kW);2. High-pressure hydraulic system (25-31.5MPa) + three-stage filtration;3. Full anti-corrosion treatment (salt spray resistance ≥ 1000 hours, IP66 protection).
