1.Main beam

The main beam of an electric hanging orbit crane, especially for a power plant application, is a critical structural component designed to support and carry the loads during lifting operations. The specifications and design considerations of the main beam vary depending on the type of crane and its specific use.

It is typically made of high-strength steel (e.g., Q345B, Q235, or alloy steel) to ensure durability and resistance to heavy loads.The main beam is often an I-beam or box-shaped structure, designed to distribute the load evenly across its span.The main beam must be able to withstand both vertical and lateral forces. It will usually have reinforcements in high-stress areas to avoid deformation during operation.

Power plant cranes typically handle large, heavy loads, often involving heavy machinery, large transformers, or power plant components. Therefore, the main beam is designed with a high load-bearing capacity, which can range from several tons to hundreds of tons, depending on the crane's intended use.The crane may have additional safety factors built in, such as overload limiters, to prevent accidents.

The span of the main beam is typically designed to cover the full width of the area to be serviced by the crane, which could be anywhere from a few meters to over 100 meters in large industrial applications like power plants.For high ceiling clearance and maximum lifting height, the design of the beam will allow for proper clearance without interference with the structure above.

The beam is typically supported by end trucks or wheels that run along a fixed rail track or gantry. These tracks are designed to support the weight of the crane, its load, and any additional forces encountered during operation.

Traveling Mechanism: The beam is usually equipped with electric motors that control the horizontal (lateral) movement along the track. The motors are carefully chosen based on the load capacity and operational speed required.

 

Lifting System

The lifting system of an electric hanging orbit crane for a power plant is designed to handle heavy loads and work in demanding industrial environments like power plants.

Girder (Bridge): The main structural element that spans the work area. It typically consists of a horizontal beam, supported by end trucks or wheels.

End Trucks: The units at both ends of the crane that move along the rail or track, allowing the crane to move horizontally across the work area.

Motorized Hoist: A key component that raises and lowers loads. The hoist is typically powered by an electric motor, which drives a chain, rope, or cable drum.

Lifting Mechanism: Usually consists of a drum or a chain block, around which the lifting medium (cable, chain, etc.) winds. The hoist is designed to support the weight of the load and operate reliably in heavy-duty environments.

Load Capacity: Lifting systems in power plants often have large load capacities (up to hundreds of tons), depending on the application (e.g., turbine assembly, maintenance, etc.).

Track System: The crane moves along a circular or linear track system, often mounted overhead on the plant's structure. For an "electric hanging orbit crane," this track would allow the crane to move in a defined orbit or path around a specific area, providing flexible movement over large workspaces.

Rail System: Rails are mounted on the overhead structure or on the ground. The crane travels along these rails using wheel assemblies, which are powered by electric motors. In some cases, the crane may move along a custom-designed track to follow a path suited for a specific operational process.

 

 

3.End carriage

The end carriage of an electric hanging orbit crane for a power plant is a critical component responsible for supporting and guiding the movement of the crane along the tracks or rails. It typically houses the wheels, drive mechanism, and support structure that allow the crane to move horizontally along the crane runway.

Function of End Carriage:

Movement Support: The end carriage ensures the crane can travel along the overhead track or runway. It supports the load and maintains the stability of the crane during operations.

Structural Support: It connects the bridge structure (which holds the hoist and other lifting equipment) to the rail system, ensuring the bridge can move freely along the tracks.

Guiding the Crane: The end carriage houses the drive mechanism (usually a motor and reducer) to propel the crane across the runway. It also includes wheels that run on the tracks.

Key Components of End Carriage:

Wheels: The wheels are designed to handle the weight of the crane, the load, and any dynamic forces during movement. They are typically made of high-strength materials like steel and are designed to operate on specific rail profiles.

Drive Mechanism: This can consist of an electric motor, gear reducer, and coupling system. The motor drives the wheels, allowing the crane to move horizontally.

Frame/Support Structure: The frame of the end carriage is designed to support the crane bridge, the hoist, and the load. It is typically made of welded steel to ensure strength and durability.

Bearings: High-quality bearings are used to reduce friction between the wheels and tracks and to allow smooth movement.

Electrical System: Includes electrical connections for powering the motor, and in some cases, safety and control systems for overload protection, speed control, and emergency stop mechanisms.

4.Crane travelling mechanism

1) Working principle

The crane receives electrical power through cables or an overhead conductor system. The electrical power is fed to the motors, which drive the crane's movement.The crane operator uses a joystick, pendant, or remote control to send commands to the control system. These commands activate the motors that drive the wheels or trolleys, enabling the crane bridge to move along the tracks.The speed at which the crane moves is typically adjustable. It is controlled through the motor speed or variable-frequency drives (VFDs), allowing precise control.As the crane moves horizontally, it can be used to transport heavy loads across the power plant. The hoist mechanism (often with a trolley) allows for vertical lifting and lowering of loads, while the traveling mechanism enables horizontal movement.The crane's traveling mechanism includes a braking system that ensures controlled stopping and safety during operations.

2) Functions of the crane operating mechanism

The crane traveling mechanism of an electric hanging orbit crane, particularly in a power plant, plays a crucial role in ensuring the efficient and safe movement of heavy loads across a wide area. Here are the key functions of the crane's traveling mechanism:

Movement of the Crane Along the Track:The primary function of the traveling mechanism is to move the entire crane structure horizontally along the rail or track system installed on the crane's supporting structure.The mechanism uses wheels or trolleys that are driven by motors to move the crane horizontally, typically in a longitudinal direction (across the plant or work area).

Horizontal Load Transport:The traveling mechanism enables the crane to move heavy loads (such as equipment, materials, and tools) horizontally across the plant, allowing for precise placement or transport between various sections of the facility.This helps in tasks like transferring coal, raw materials, equipment, or even assembling power plant machinery in the designated areas.

Power Supply and Control:The traveling mechanism is powered by electric motors that are connected to a power supply. These motors are responsible for controlling the speed, direction, and movement of the crane.The crane operator controls the mechanism through a control panel or remote system, ensuring safe operation.

Precision and Safety:The traveling mechanism is designed to operate with high precision, which is vital in a power plant where load positioning is critical, such as during equipment maintenance or installation.It also includes safety features like overload protection, anti-collision sensors, and emergency stop systems to ensure safe operation within the plant environment.

Coordination with Other Crane Movements:The traveling mechanism works in tandem with other crane movements, such as hoisting (vertical movement) and trolley movements (horizontal load shifting).This coordinated operation allows the crane to perform tasks like lifting, transporting, and placing heavy equipment accurately within tight spaces, such as around turbine halls, reactor buildings, or transformer stations.

5.Trolley travelling mechanism

1) Structural composition

The trolley traveling mechanism of an electric hanging orbit crane (often referred to as an electric overhead crane or EOT crane) in a power plant typically consists of several key structural components that work together to allow for the precise movement of the crane along its track or runway.

Trolley Frame: The trolley frame is the main structural component that supports the crane's load and various mechanical systems. It is designed to be rigid and durable to bear the dynamic loads during operation. Usually fabricated from steel or welded sections to ensure strength and stability.It provides a platform for other components like the hoist and motor and allows movement along the runway.

Motors and Gearboxes: These are the driving force behind the trolley's movement along the track. They are typically AC motors that provide the necessary torque for travel.A reduction gearbox is used to step down the motor's high-speed output to the lower speed required for the trolley's travel motion.To drive the trolley along the runway track at a controlled speed.

Travel Wheels and Axles: These are mounted on the trolley and are in direct contact with the overhead crane's track. They are designed to withstand heavy loads and dynamic forces. Typically made of high-strength steel or cast iron.These are mounted on the trolley frame and carry the travel wheels. They ensure proper alignment and smooth movement.To allow the trolley to travel along the track (overhead crane runway) smoothly and with minimal friction.

End Trucks: End trucks are structural units located at both ends of the trolley frame. These trucks house the motors, wheels, and other components needed to guide the trolley along its path.End trucks allow the transfer of the trolley's load from the fixed runway structure to the mobile trolley, supporting movement across the track.

Braking Mechanism: The trolley's electric traveling motor is usually equipped with electric brakes to stop the movement of the trolley. They help prevent uncontrolled movement and provide smooth deceleration.Sometimes, mechanical disc or drum brakes are included for additional safety and control.To control the speed of the trolley and stop it safely during operation.

2) Function of the trolley operating mechanism

Horizontal Movement of the Load:The primary function of the trolley mechanism is to move the crane hook (or lifting device) horizontally along the beam (also known as the crane girder or runway) of the overhead crane system. This movement allows the crane to place the load at different positions across the entire working area, such as above equipment, machinery, or other structures in a power plant.

Load Positioning:The trolley mechanism ensures precise positioning of the load, which is crucial in power plant settings where heavy equipment or materials need to be moved safely and efficiently. Accurate positioning is essential for tasks such as assembling machinery, lifting and placing heavy components, and carrying out maintenance tasks.

Motorized Drive and Control:The trolley is typically powered by an electric motor, which drives the wheels of the trolley along the crane runway. The speed and direction of the trolley's movement are controlled via an electrical system, providing flexibility and precision in positioning the load. The motor may be operated with variable speeds, allowing for careful handling of sensitive or heavy loads.

Structural Support:The trolley is mounted on the crane girder and is designed to bear the weight of both the load and the lifting mechanism (hook, hoist, etc.). It needs to be sturdy enough to handle the forces generated by lifting and moving heavy loads, often in challenging industrial environments like power plants.

Safety and Load Control:The traveling mechanism is designed with safety features to ensure stable movement. It includes limit switches, braking systems, and overload protection devices to prevent accidents or mechanical failure during operation. In a power plant, where there might be a need to handle critical or hazardous equipment, these safety features are crucial to avoid accidents or damage to equipment.

6.Crane wheel

The crane wheel for an electric hanging orbit crane used in a power plant plays a crucial role in the overall functioning and safety of the crane system. These cranes are typically employed for lifting heavy loads, such as equipment and materials, within power plant facilities. The wheels are part of the crane's running gear and allow the crane to travel along the bridge or rail system.

Crane wheels are usually made of high-strength steel or alloy to withstand the heavy loads and stresses they encounter.Given the constant movement and load-bearing requirements, the wheels must be able to withstand wear and tear over time. Some materials may be treated to increase their hardness and resistance to wear.The tread of the wheel (the part in contact with the track) is often designed for optimal grip and smooth operation. A crowned tread or a tapered wheel profile can help distribute the load evenly and reduce wear on both the wheels and the rail.The diameter of the crane wheels is important for load distribution and stability. Larger wheels may be used for heavier cranes or when high-speed travel is required.

Functionality:

Support: Crane wheels support the weight of the crane's structure, including the load it's carrying, and ensure smooth movement along the track.

Movement: The wheels facilitate horizontal movement of the crane along the gantry, ensuring that the crane can reach different areas of the plant. They are often connected to a drive mechanism (typically electric motors) that powers the crane's movement.

Stability: The crane wheel system ensures the stability of the entire crane, preventing tipping and ensuring smooth and accurate motion along the track or rail system.

Wheel Types:

Single Flanged Wheels: These are commonly used on cranes that run on rails and offer stability in the lateral direction.

Double Flanged Wheels: These have a flange on both sides of the wheel, which can offer additional stability and help prevent derailing, especially in high-speed applications.

Crane Hook

A crane hook in the context of a trussed-type electric hoist gantry crane is a critical component designed for lifting and transporting loads.

Function

Lift and lower loads by attaching to the load's lifting points.

Hold the load securely while it's being moved across the crane's travel span.

Allow for quick attachment and detachment from loads, depending on the specific operation.

Types of Crane Hooks

Single Hook: The most common type, used for lifting loads with a single point of contact.

Double Hook: Used when extra stability is required, often for heavy or unevenly distributed loads.

Specialty Hooks: These can be customized for unique applications, such as magnetic or grab hooks for specific industries.

Motor

The motor for an electric hanging orbit crane in a power plant is a critical component that drives the crane's movement, including hoisting, traversing, and possibly rotating operations. For such an industrial application, the motor needs to be robust, reliable, and capable of operating under heavy load conditions.

Motor Type:

AC Motors (Alternating Current): These are commonly used for electric cranes due to their efficiency, durability, and ease of maintenance. Specifically, squirrel cage induction motors are often preferred for their robustness and cost-effectiveness.

DC Motors: Less common today but may still be used for precision control in applications requiring variable speeds and high starting torque.

Synchronous Motors: Used in applications where precise speed control and constant speed under varying loads are important.

The motor's power rating should be sufficient to handle the maximum load that the crane will carry. This includes not just the weight of the load itself but also factors like friction, wind load (in open areas), and the nature of the movements (hoisting, traveling, or rotating).The typical power range can vary from a few kW for light-duty cranes to hundreds of kW for heavy-duty applications in power plants.
