Double Girder EOT Crane
Double Girder EOT Crane is core equipment for industrial heavy-load material handling. It has stable structure and strong load-bearing capacity make them widely used in heavy machinery plants, metallurgical workshops, ports, and other locations requiring the handling of large or heavy cargo, providing reliable support for high-load, large-volume material handling.
- Lifting Capacity(ton):5~800 ton
- Lifting speed(m/min):1.5~12.5 m/min
- Span:10.5-34 meters
Products Description:
Double-girder EOT cranes are heavy-duty lifting solutions engineered for efficient material handling in factories, workshops, and warehouses. Featuring a dual-main-girder structure, they offer superior strength, stability, and higher lifting capacity compared to single-girder cranes.
The Double Girder EOT Crane mainly consists of the bridge girders, end carriages, trolley with hoist, runway system, and electrical control components. Below are the functional characteristics of each component:
-
Double Main Girders:
Two box-type or truss-type main girders are arranged in parallel and connected by cross beams, forming a stable load-bearing framework. This configuration offers greater load capacity and span range, enabling coverage of a wider operational area.
-
End Beams:
Mounted at both ends of the main girders, these beams house drive mechanisms that propel the crane longitudinally along the rails, ensuring smooth operation even under heavy loads.
-
Trolley:
Positioned between the two main girders, it comprises a hoisting mechanism, trolley frame, and travel mechanism. It vertically lifts and horizontally moves loads along the main girders, delivering high operational precision and enabling fine positioning.
-
Electrical Control System:
Includes control cabinets, operator handles, or remote controllers, integrated with overload protection and limit switches to ensure safe and reliable operation.
Advantages:
Double Girder EOT Crane is a robust, smooth-running, high-capacity lifting device widely used in factories, warehouses, steel structure manufacturing, and large-scale engineering projects. It offers significant advantages including high efficiency, precision, and safety reliability.
-
High Load Capacity:
Featuring a dual-girder design, it handles lifting demands ranging from 5 to 800 tons.
-
Structural Stability:
The bridge frame exhibits high rigidity, ensuring smooth operation while minimizing equipment vibration and deformation.
-
Wide Operational Range:
Enables three-dimensional material handling, covering the entire work area.
-
Precise Operation:
Equipped with an electric control system for smooth starts/stops and accurate positioning.
-
Easy Maintenance:
Key components feature standardized designs for convenient inspection and upkeep.
-
Customizable Design:
Span, lifting capacity, and control methods can be tailored to suit diverse factory structures and operational requirements.
Application Scenario:
- Heavy Machinery Plants: Used for the assembly, handling, and installation of large machine tools and heavy equipment, such as the transshipment of heavy components like steam turbines and rolling mills.
- Metallurgical Industry: Used for lifting ladles, billets, and steel products in steel mills and steelmaking plants, withstanding high temperatures and harsh environments.
- Ports and Logistics Hubs: Responsible for the loading, unloading, and stacking of containers and large cargo, improving port cargo turnover efficiency.
- Energy Industry: Used for the handling of large equipment such as generator sets and boilers in hydropower stations and thermal power plants, supporting the construction and maintenance of power facilities.
- Bridge and Construction Engineering: Used for the lifting and relocation of bridge components and large prefabricated parts, facilitating the construction of large scale infrastructure projects.
