Port Machinery
Fixed Crane
Fixed Cranes refer to jib cranes that are anchored to foundations or supported on bases, operating solely at fixed locations within ports. Compared to portal cranes in structure, they retain hoisting, luffing, and slewing functions but lack gantry travel mechanisms and portal frame structures in its metal construction. Their defining characteristic is operation confined to a fixed position, yet it offers simpler structural design and lower manufacturing costs.
1. Unique Design of Slewing Bearing that Enables Crane-Synchronized Lifespan
Our decades-accumulated machining expertise and membership on China's Boom Crane Standardization Committee ensure the slewing bearing – the most critical mechanical component of portal cranes – achieves identical operational lifespan as the entire machine.
2. Low-Center-of-Gravity Design
The high-boom, low-slewing-platform design concept lowers the center of gravity of portal cranes, significantly enhancing overall machine stability.
3. Special Steel Wire Rope Reeving with Low-wear Design
Utilizing same-direction parallel winding, this method significantly reduces wire rope wear, extends service life by over 20%, and lowers maintenance and replacement costs.
4. Quick-Change Spreader System
The quick-change interface enables seamless switching among grabs, hooks, and container spreaders within 3-5 minutes.
5. Full Electric Drive
Eco-friendly operation with 380V–20kV power compatibility
6. Steel Rail Travel System
Forged steel wheels support higher loads with minimal wear, eliminating frequent wheel replacements and slashing maintenance costs
7. Multi-Level Safety Protections
Intrinsic crane safety remains our core objective. The redundant design of multiple safety mechanisms,combines real-time data tracking via cloud-based monitoring systems to ensure operational safety.
8. High-Efficiency Handling
Bulk Cargo: Up to 1,200 t/h
Containers: Up to 30 TEU/h
9. High Efficiency and Energy Conservation
Continuous operation reduces interruptions, eliminating secondary transport links compared to traditional processes, thereby lowering energy consumption and costs.
10. Automated Operation System
Portal cranes memorize material loading/unloading positions and operation paths. Combined with grab anti-sway, precision positioning, and collision avoidance algorithms, this enables fully automatic grab operations.
11. Anti-Sway Grab Control System
Modeling of the portal slewing system enables calculation of grab swing angles. Intelligent control regulates slewing and luffing speeds to eliminate swing, achieving effective sway elimination.
12. Energy Regeneration System
Energy regeneration system converts electrical energy generated during load descent or motor deceleration and feeds it back into the grid, achieving energy recovery to meet energy-saving and emission-reduction objectives.
13. Energy Recovery System
Stores electrical energy generated during load descent or motor deceleration in battery banks or supercapacitors, releasing it during subsequent operations. This enables energy reuse while reducing the entire system's input power demand.
14. High Power Factor & Low Harmonic Distortion
Incorporating active harmonic filtering and reactive power compensation technology to raise power factor, reduce line losses and optimize electrical power quality.
