Deck Knuckle Boom Crane
Product Overview
The deck knuckle boom crane is a specialized lifting device installed on the deck of a vessel. Featuring a folding boom design, it offers a compact structure, flexible operation, and space-saving advantages. This equipment is widely used on offshore platforms, engineering vessels, supply ships, and various types of marine vessels for cargo handling, equipment hoisting, and emergency operations.
Main Features
1. Knuckle Boom Structure: Multi-section arms fold for compact storage and deploy during operation, ideal for vessels with limited deck space.
2. Flexible Operation: Equipped with a fully hydraulic drive system and multi-axis control, supporting precise positioning and complex working environments.
3. High Safety: Multiple safety systems such as overload protection, emergency stop, and anti-sway control ensure the safety of personnel and equipment.
4. Strong Adaptability: Designed with excellent corrosion resistance and marine-grade materials, suitable for continuous operations in harsh marine conditions.
5. Customizable Design: Optional lifting capacities, working radii, control modes (manual or remote), and power sources (electric or hydraulic) are available to meet specific needs.
Structural Components
The deck knuckle boom crane mainly consists of the base, column, main boom, jib, hydraulic cylinders, winch system, slewing mechanism, control platform, and electrical system.
- Base and Column: Reinforced structural connections ensure stability under heavy loads.
- Main Boom and Jib: Hinged connections allow folding and unfolding operations.
- Hydraulic System: Provides strong power for hoisting, slewing, and telescoping.
- Control System: Offers manual, remote, or remote-monitoring operation options for simple and reliable control.
Working Principle
The crane performs hoisting, slewing, luffing, and telescoping operations via its hydraulic system. The boom can be adjusted flexibly to reach the target position, enhancing both operating precision and efficiency. The control system monitors and optimizes motion parameters in real time to adapt to different operational tasks.
Materials and Craftsmanship
The crane is made of high-strength low-alloy structural steel. Critical components are stress-analyzed and fatigue-tested to ensure structural safety. Surfaces are treated by sandblasting and coated with marine-grade anti-corrosion paint, ensuring long-term durability in marine environments.
Manufacturing and Inspection Standards
The product strictly complies with relevant international and industry standards such as ISO, DNV, ABS, and CCS. Full-process quality control is implemented during manufacturing. Key components undergo non-destructive testing and load tests. Full assembly and operational simulation are conducted before delivery to ensure performance reliability.
Applications
- Offshore platform supply operations
- Cargo handling on ship decks
- Deployment and recovery of surface/subsea equipment
- Maritime emergency lifting and rescue
