Polygon Boom Profile: Octagonal/hexagonal cross-section delivers superior alignment and high bending resistance.
Baosteel 700 Steel: High-strength steel plates optimize the structural weight-to-strength ratio.
Compact Footprint: Lower deadweight and higher payload with a low center of gravity for enhanced transit stability.
Balanced Hook Pulley: Lateral guide wheels and limit plates ensure uniform force and longer bearing lifespans.
Enlarged Internal Pulley: Maximized diameter improves load-telescoping capability and extends wire rope service life.
Optimized Boom Sliders: Large-scale slider design minimizes specific pressure and reduces boom wear.
Integrated Boom Head: Unified structural design provides significantly higher load-bearing capacity than split alternatives.
Dual-Cylinder Telescopic: Two-cylinder setup with wire rope pulleys protects internal rigging and maintains mid-range capacity.
Telescopic Boom Model: Engineered specifically for heavy-duty lifting operations in open maritime environments.
Knuckle Boom Model: Dual four-bar luffing mechanism with reverse folding excels in confined/narrow spaces.
Negative Angle Operation: Dual knuckle booms feature upward articulation to easily access ultra-low clearance zones.
Quick-Change Attachments: Supports rapid modular coupling with winches, augers, aerial baskets, hydraulic grabs, and cargo forks.
Multi-Scenario Solutions: All-in-one system for marine lifting, drilling, aerial work, demolition, and material handling.
Disc-Spring Braking: Equipped with counter-balance valves and friction brakes for smooth, high-efficiency operations.
Hydraulic Lowering Balance: Utilizes dedicated balance valves to counter loads safely during descent.
Reverse Cylinder Layout: Flange-connected balance valve eliminates exposed external piping, preventing leaks and impacts.
Planetary Gear Motor: Low-speed, high-torque configuration matched with a large-diameter drum.
Dual Planetary Reducer: Delivers exceptionally stable hoisting performance with minimal braking impact.
Multi-Plate Friction Brake: Provides high braking torque, silent operation, and an extended service lifespan.
Smart Load Moment Limiter: Real-time load-ratio tracking with automatic motion cut-off during overload conditions.
Triple Anti-Collision: Features automatic braking, buffer-stop controls, and a wedge-locked anti-backlash device for over-winding/unwinding protection.
Wireless Remote Control: Enables precise, proportional control from up to 50 meters away in complex environments.
High-Position Seating: Provides an unobstructed, zero-blind-spot view for direct and accurate positioning.
Wire Rope Protection: Anti-derailment design on lower pulleys guarantees high stability during hoist cycles.
