Product Description

high-performance hydraulic excavator 

Our high-performance hydraulic excavator is engineered for durability, efficiency, and versatility in construction, mining, and earthmoving projects. Designed with advanced technology and robust materials, this excavator ensures superior digging force, smooth operation, and fuel efficiency. Suitable for heavy-duty applications, it delivers exceptional performance in diverse terrains and working conditions.

Specification

Applications

1. Large-scale offshore engineering construction: Hoisting and precise positioning of super-large marine engineering components such as cross-sea bridge piers, undersea tunnel immersed tubes, and artificial island structural parts.
2. Support for deep-sea resource development: Deployment and recovery of deep-sea drilling equipment, seabed mining machinery, large underwater observation platforms, as well as laying of deep-sea oil/gas pipelines.
3. Operation and maintenance of giant ships and platforms: Hoisting heavy components such as main engines and deck equipment for ultra-large oil tankers, LNG carriers, and semi-submersible drilling platforms, or replacing entire modules.
4. Large-scale offshore wind power construction: Hoisting giant components such as towers, blades, and nacelles of high-power wind turbines above 10MW, covering the installation and maintenance of deep and distant offshore wind power projects.
5. Cross-ship transfer of special cargo: Transferring super-large equipment (such as nuclear power modules, giant pressure vessels) between semi-submersible ships and heavy lift ships to realize cross-sea heavy material allocation.
6. Emergency rescue and heavy salvage: Participating in the overall salvage of 10,000-ton sunken ships and offshore platform wrecks, or hoisting damaged large marine engineering equipment to support offshore accident rescue.
7. Super-heavy port loading and unloading: Loading and unloading overweight and overwidth cargo (such as large bridge steel structures, marine engineering modules) for special ships, making up for the load limitations of conventional port cranes.

Key Configurations

Ultra-strength telescopic folding boom (multi-section alloy steel structure)
High-power hydraulic drive system (including high-pressure pump, hydraulic motor)
Super-large tonnage hoisting mechanism (heavy-duty winch + high-strength hook)
Full-slewing support device (360° rotation, precise positioning)
Anti-corrosion protection system (anti-salt spray coating, sealing design)
Intelligent safety control (torque limitation, overload protection, wind and wave compensation)
Dual-mode control terminal (operation cabin + remote control)

Core Advantage

High space utilization: The folding boom can be folded and stored, saving more space compared to straight boom cranes. It is suitable for narrow scenarios such as ship decks and offshore platforms without affecting the operation of other equipment.
Adaptability to extreme marine environments: Adopting salt spray-resistant, corrosion-resistant materials and multi-layer anti-corrosion coatings, equipped with wind and wave stabilization systems, it can operate stably in high humidity, strong salt spray, and heavy wind and wave environments.
Precise and flexible operation: Integrating hydraulic servo control and intelligent sensing technology, it realizes fine adjustment and precise positioning under heavy loads, reducing impact on the lifted objects, and is suitable for lifting precision equipment or dangerous goods.
High safety redundancy: Equipped with multiple protection devices such as overload limiters, torque limiters, and emergency brakes, it monitors parameters in real time, warns or shuts down in case of abnormalities, significantly reducing safety risks.
Multi-functional adaptability: Can be equipped with different accessories such as hooks, grabs, and lifting beams, flexibly coping with various scenarios such as lifting, salvage, and installation, improving comprehensive utilization efficiency.
