What is EOT Crane?

EOT crane full form is an electric overhead travelling crane. It is an electrically powered, mobile crane that travels on fixed tracks within a workshop or factory. Operators use this lifting equipment to lift and move heavy objects. Compared to diesel-powered equipment, EOT cranes are more efficient, less expensive to operate, quieter in operation, and have a lower environmental footprint. Next, this article will introduce what is EOT Crane, as well as its price, application, parts, etc. So that you can get familiar with and understand EOT cranes.

Single Girder EOT Crane

Double Girder EOT Crane

What is an eot crane?

An EOT Crane is a type of lifting equipment primarily consisting of a main beam, end beams, an electric hoist or trolley, and an electrical control system. It can operate forward, backward, left, right, and upward, as well as downward. Factories primarily use electric overhead travelling cranes for lifting and moving heavy-duty materials in workshops, warehouses, and production lines. EOT Cranes’ compact structure, high safety, and stable operation, electric overhead travelling cranes widely used in manufacturing, metallurgy, energy, and logistics, etc.

EOT Crane Types

EOT cranes are classified into single-girder EOT cranes, double-girder EOT cranes, and suspension EOT cranes according to their structure and lifting capacity. The following will introduce different types of EOT cranes.

Single Girder EOT Crane

A single-girder EOT crane primarily consists of a single main girder, two end beams, running mechanism, electric hoist, and other key components. Operators use it to handle small to medium tonnages and medium spans of material. Typically, a single-girder EOT crane has a load capacity of 1 to 32 tons.

Double Girder EOT Crane

A double-girder EOT crane is a lifting equipment consisting of two main beams. It is mainly used for large-tonnage, large-span, and high-intensity material handling operations. Compared with single-girder EOT cranes, the double-girder structure gives it higher load capacity, greater lifting height, and stronger stability. Double-girder EOT crane with a lifting capacity of up to 800 tons.

Underslung Suspension EOT Crane

The underslung suspension EOT crane end beam track is installed under the roof of the building structure, and the main beam slides along the track. This type of equipment does not occupy floor space and has low height requirements for the factory building. Users use it in environments with limited space or densely packed floor equipment. Underslung suspension cranes have a lifting capacity range of 0.5-10 tons.

What is EOT Crane Used for?

An EOT crane has a large lifting capacity, stability, safety, and high space utilization. It is suitable for diverse industrial scenarios and environments.

• Industrial Workshop: In the machinery manufacturing workshop, an EOT crane can lift large machine tool parts, blanks, finished products, etc. It also cooperates with the production line to complete the transfer and assembly of materials.
• Automotive Manufacturing: Electric overhead travelling crane lifts heavy parts such as engines and body frames in the automobile manufacturing workshop.
• Steel Mills: In the metallurgical workshop, it can lift high-temperature or heavy materials such as ladles, ingots, and steel. It can meet the material handling needs during smelting and rolling.
• Warehousing and Logistics: In large warehouses and logistics centers, a bridge crane stacks and moves containers, pallets and other goods.
• Energy Industry: In power plants, it installs and repairs large equipment such as steam turbines and generators. And it lifts heavy power materials such as transformers and cables. In hydropower stations, it can lift turbine parts, gates, etc..
• Building Materials: In prefabricated component factories, concrete prefabricated panels, steel structure components, etc. are lifted. At the bridge construction site, it cooperates with the lifting of large components such as bridge sections and steel box girders.

EOT Crane Working Principle

EOT cranes complete lifting tasks through the coordinated work of various parts and operator control. The bridge supports the entire structure. The end beam running mechanism operates on tracks located on either side of the plant building, allowing the crane to move longitudinally. The trolley on the main beam, driven by its drive mechanism, moves laterally, while the hoist mechanism on the trolley lifts the material vertically. Through the coordinated movement of the overhead travel mechanism’s longitudinal motion, the trolley travel mechanism’s lateral motion, and the lifting mechanism’s vertical motion, cargo is moved from point A to point B.

Parts of EOT Crane

The EOT crane consists of a main girder, an end girder, a lifting mechanism, a trolley running mechanism, an overhead travel system, a rail, a control system, a walking platform, and other components. Next, we will introduce each parts:

• Main Beam: The main load-bearing structure of the EOT crane, responsible for supporting the lifting mechanism and all loads.
• End Beam: Connects the two ends of the main beam, supports the entire bridge structure, and has running wheels installed at the bottom to enable the crane to move longitudinally along the factory track.
• Lifting Mechanism: It is installed on the main beam, responsible for the vertical movement of materials.
• Crane Operating mechanism: This mechanism is responsible for driving the entire equipment to move longitudinally along the track.
• Electrical Control System: Provide power for the entire device, and the operator controls the lifting, traveling, braking, and other actions of the crane. It typically includes a power distribution cabinet, control panel, push-button controller, or wireless remote control. Some systems also include variable frequency speed regulation and safety monitoring systems.
• Hook Set: The hook is equipped on the lifting mechanism and is the component that directly contacts the load.
• Safety Devices: Manufacturers equip EOT cranes with limit switches, overload protectors, buffers, emergency power-off devices, etc.
• Control Device: EOT cranes equipped with a cab or remote control device, which are divided into aerial operation and ground operation.
