Introduction of Four Link Portal Crane
This heavy-duty portal crane is engineered for high-performance container and bulk material handling in demanding port environments. Its robust construction integrates a reinforced steel framework, precision-engineered lifting systems, and a versatile spreader interface compatible with hooks, grabs, and specialized container attachments.
Core operational systems include a synchronized lifting mechanism, a smooth luffing assembly for precise boom positioning, a fully rotational slewing ring for 360-degree coverage, and a stable travel mechanism for seamless mobility across the yard. The primary steel components—including the jib, A-frame support, slewing platform, and reinforced gantry structure—are designed for long-term structural integrity under cyclic loading.
Manufactured in compliance with international safety and design protocols (including GB17495-1998, GB6067-85, GB3811-2008, ISO, FEM, and JIS standards), this crane offers a balanced four-bar linkage configuration with a mobile, full-revolving superstructure. Operators benefit from a spacious, ergonomic cabin offering excellent visibility and low ambient noise, contributing to both precision control and fatigue reduction.

Applications of Four Link Portal Crane
The four-link portal crane serves as essential infrastructure across multiple heavy-industry sectors, delivering reliable material movement solutions where precision, durability, and high load capacity are required.
1. Seaport Container & Bulk Handling
At modern port terminals, this crane efficiently manages container stacking, vessel loading/unloading, and bulk commodity transfer. Its full-revolving superstructure and long jib enable broad coverage across ship berths and storage yards, significantly reducing vessel dock time and optimizing terminal throughput.
2. Shipyard Logistics & Vessel Servicing
Within shipbuilding and repair yards, the crane supports assembly processes by transporting heavy components such as engine modules, steel plates, and prefabricated sections. Its stable gantry base and precise hoisting control allow safe positioning in congested work areas, facilitating streamlined production and maintenance workflows.
3. Metallurgical & Raw Material Transport
In ferrous and non-ferrous metal plants, the unit handles raw materials—including scrap metal, coils, and ingots—between storage, melting, and processing zones. Its heat-resistant components and smooth control systems ensure operational safety and continuity even in high-temperature environments near furnaces or casting lines.
4. Major Construction & Infrastructure Projects
On large-scale construction sites, the crane assists in erecting structural steel, placing precast concrete elements, and moving heavy machinery. Its high lifting height and excellent mobility make it suitable for open-site logistics, helping accelerate project timelines while maintaining strict safety standards.
5. Waste Processing & Recycling Operations
Within recycling centers and waste management facilities, the crane is utilized for sorting, stacking, and transferring recyclables and solid waste. Equipped with grabs or magnets, it efficiently handles bulk materials such as municipal solid waste, metal scrap, and recovered commodities, supporting both environmental operations and material recovery workflows.
From busy international ports to heavy industrial complexes, the four-link portal crane continues to prove its adaptability, strength, and critical role in enabling efficient, large-scale material handli
