Telescopic Marine Crane

Brand: Henan Hengkun Crane Co., Ltd.
Applications: Offshore supply vessels, wind farm installation ships, cargo carriers, and marine platforms requiring compact, high-reach lifting solutions for cargo handling, equipment deployment, and subsea operations in dynamic maritime environments.

Product Overview

Our Telescopic Marine Crane is engineered for versatile, space-saving lifting on ships and offshore installations. Featuring a hydraulic telescopic boom that extends and retracts seamlessly, this crane maximizes operational flexibility while minimizing deck space usage. Designed to withstand corrosive saltwater, high winds, and rolling seas, it delivers precision, durability, and safety for loads up to 150 tonnes, making it ideal for offshore logistics, wind turbine installations, and emergency rescue operations.

Key Features & Benefits

Telescopic Boom Design
- Multi-stage hydraulic boom (3–5 sections) adjusts working radius from 8 to 40 meters without requiring additional deck space.
- Compact stowed length for easy storage and transport.
Marine-Grade Durability
- ISO 12944 C5-M certified anti-corrosion coatings and stainless steel components for saltwater resistance.
- IP68-rated hydraulic systems and waterproof electrical enclosures.
Dynamic Stability
- Active Heave Compensation (AHC) or Passive Motion Damping systems to counteract vessel movements in rough seas.
- Reinforced pedestal mount for stability on rolling decks.
Safety & Precision
- Overload protection, dual braking systems, and emergency stop functions.
- Laser-guided load positioning (±5mm accuracy) and anti-collision sensors.
Energy Efficiency
- Regenerative hydraulics reduce energy consumption by 20–30%.
- Hybrid power options (diesel-electric or shore power compatibility).
