Introduction of Single Jib Portal Crane
Engineered for efficiency in congested port environments, our port cranes feature a innovative design where the rotating column connects to the vertical column, or alternatively, a large rolling bearing slewing device links directly to the gantry. This core engineering principle significantly minimizes the tail swing radius of the upper structure. Simultaneously, the gantry framework is optimized to reduce the overall pier coverage area—the ground-level footprint of the crane—enabling multiple units to work seamlessly side-by-side on the same vessel. This versatile design, proven in ports, is also highly effective in shipyards and large-scale construction sites like hydroelectric power stations.
Features of Single Jib Portal Crane
Operational Mechanics & Key Features:
The crane's functionality is driven by four primary mechanisms: hoisting, slewing (rotation), luffing (boom raising/lowering), and travelling. The first three are mounted on the rotating superstructure, which completes a full cycle with every operation. This section also supports a luffing boom (single or combination type) and the operator's cab. The travelling mechanism, located at the gantry base, allows for precise positioning of the entire crane along the quay. For bulk material handling, optional attachments like a telescopic chute and belt conveyor can be integrated, dramatically boosting productivity when used with a grab bucket. Safety is paramount, with standard protections including overload or moment limiters, rail clamps, and comprehensive electrical safeguards.
Floating Crane Capabilities:
Our floating crane model is a self-contained lifting solution installed on a vessel, ideal for various cargo handling tasks. It complies with the China Classification Society (CCS) "Code for Lifting Appliances of Ships and Offshore Installations" (2007) and its subsequent amendments. This machine utilizes a balanced, gear-rack luffing system for smooth and precise boom movement.
Core Components & Control:
The floating crane is comprised of several integrated systems:
Power Mechanisms: Dedicated hoisting, luffing, and slewing systems.
Structural Framework: The jib system, main column, turntable, and support cylinder.
Control & Access: A fully-equipped machine room, operator's cab, and safe access ladder/railing systems.
Control System: An advanced electrical control system for seamless operation.
It can be configured for use with a hook or a grab. The crane performs hoisting, luffing, and 360-degree continuous rotation. These motions can be conducted individually or in synchronized combination. All major mechanisms utilize AC variable frequency control for smooth, precise speed regulation. Essential limit switches and interlocking protection devices are standard across all systems to ensure operational safety and equipment integrity.

Applications of Single Jib Portal Crane
The Single Jib Portal Crane serves as a cornerstone of modern material handling, engineered to drive productivity across diverse operational landscapes. Its design directly addresses the critical need for accelerated cargo transfer, rapid vehicle turnaround, and streamlined transshipment processes between vessels and land transport.
Primary Industrial Applications
This crane delivers exceptional performance in the following key sectors:
1. Maritime Ports & Container Terminals
In bustling port environments, our Single Jib Portal Crane is pivotal for managing the continuous flow of containerized and bulk goods. It excels in directly transferring cargo from ship to shore (and vice-versa), drastically reducing vessel berthing time. Its compact swing radius and optimized ground footprint are specifically engineered for busy quaysides, allowing multiple cranes to operate in unison without interference, thereby maximizing throughput in space-constrained terminals.
2. Large-Scale Construction & Infrastructure Projects
On major construction sites, this crane provides the muscle for positioning structural steel, moving pre-cast concrete elements, and placing heavy machinery. Its precise load control and significant reach enable workers to safely assemble components at elevation and across difficult-to-access areas. The crane's mobility along tracks ensures it can service different zones of a large project, from foundation work to superstructure erection, without requiring demobilization.
3. Logistics Hubs & Freight Yards
At the heart of logistics centers and storage yards, the crane revolutionizes inventory handling. It systematically stacks and retrieves heavy goods, machinery, and bulk materials, optimizing vertical storage space. This capability is crucial for cross-docking operations, where incoming shipments from trucks or trains need immediate transshipment for outbound distribution, ensuring a seamless and rapid supply chain.
4. Heavy Industry & Resource Sectors
Within the energy and mining industries, the crane tackles demanding tasks such as handling large-diameter pipes, positioning processing equipment, and managing heavy raw materials. Its robust construction and reliable lifting capacity ensure uninterrupted operation in challenging environments, supporting everything from plant maintenance to the initial stages of material extraction and processing.
5. Specialized & Niche Operations
Beyond heavy industry, this crane's adaptability makes it suitable for specialized scenarios. This includes managing large components in manufacturing workshops, handling heavy materials in recycling facilities, or supporting major maintenance operations in large industrial plants. Its configuration flexibility allows it to be tailored to unique operational challenges that require both significant lifting power and precise maneuverability.
Conclusion
By integrating a Single Jib Portal Crane into your operations, you invest in a multifaceted solution that directly enhances workflow velocity, improves site safety, and provides the robust capability to meet the demanding schedules of modern industrial and logistical projects. Its value is proven in its ability to adapt and excel across the spectrum of material handling challenges.
