In shipbuilding and repair, precision and efficiency are critical. MAXTECH’s Shipyard Jib Cranes (Portal Jib Cranes), with lifting capacities from 20t to 800t, combine robust design, smart technology, and modular flexibility to meet diverse maritime needs.
Core Design for Precision & Safety
Featuring a single - boom horizontal luffing system, these cranes ensure load stability during height adjustments, eliminating cargo sway. Hydraulic drives and torque balance technology boost operational safety by 30%, ideal for lifting ship sections or engines. The ergonomic cabin offers 360° visibility and shock - absorbing seats, reducing operator fatigue while enhancing control accuracy in complex tasks.
Modular Solutions for All Scales
Lifting Capacity: Customizable from 20 tons to 800 tons, meeting the full - scenario requirements from small - scale ship repairs to the hoisting of ultra - large cruise ship sections.
Outreach: The maximum outreach can reach 120 meters, and the minimum is 6 meters, adapting to different space constraints in narrow dry docks and open terminals.
Lifting Height: 20 - 100 meters above the rail and 10 - 50 meters below the rail, supporting high - altitude hull splicing and underwater equipment maintenance.
Power Options: Full - frequency converters cut energy use by 40% compared to diesel, supporting mains, generators, or batteries for global port compatibility.
Take 40ton Tire-Mounted Double as an example:
| Span | 11.0m |
| Hoisting Speed | 15.0~36.0m/min |
| Luffing Time | 30.0m/min |
| Slewing Time | 1.0r/min |
| Traveling Time | 10.0m/min |
Intelligent Safety Systems
Safety is prioritized through advanced technology:
1. Real - Time Monitoring: Cabin displays load, wind speed, and faults, triggering alarms/locks for anomalies.
2. Wind Resistance: Berthing anchors and automatic rail clamps withstand level 12 winds, securing equipment in harsh conditions.
3. Collision Avoidance: 4 - zone alarms (laser/ultrasonic) protect operators and obstacles during travel, luffing, and hoisting.
4. Predictive Maintenance: Central lubrication and PLC systems monitor performance, uploading fault codes to the cloud to reduce downtime by 50%.
Customization for Unique Needs
MAXTECH tailors solutions to portal crane specifics:
1. Dedicated Tools: Custom spreader beams for ship sections/engines ensure quick, balanced lifting.
2. Space Optimization: Lightweight gantries minimize wind pressure and wheel load, reducing infrastructure costs for dry docks/slipways.
3. Digital Upgrade: Optional 5G remote monitoring and digital twins enable real - time data tracking for smarter fleet management.
Versatile Applications
From giant cruise ships to container vessels, these portal gantry cranes excel in:
1. Dry Docks: Millimeter - level precision for section docking via horizontal luffing.
2. Slipways: Low - wheel - pressure design protects wooden/steel surfaces during heavy lifts.
3. Terminals: Seamless "ship - shore - warehouse" integration, boosting cargo turnover by 25% with intelligent scheduling.
