1.Main beam

The main beam of a double beam bridge crane is a critical structural component that supports the load and provides stability during crane operation. In a double beam crane, two main beams run parallel across the width of the bridge, supported by end trucks at each end. These beams are typically made of steel or other high-strength materials to handle the weight of the load being lifted, as well as the stresses and forces exerted during operation.

The main beam of a double beam bridge crane is usually made from steel, as it offers high strength and durability. Steel can also be easily welded or bolted to form the necessary structure.The beams are typically I-beams, box beams, or other shapes that offer both strength and resistance to bending under load.

The main beams support the trolley (which moves along the beams) and the hoisting mechanism (which lifts and lowers the load). The beams must be designed to carry both the dead load (the crane's weight) and the live load (the weight of the material being lifted).The beams are often braced for additional strength. This helps to prevent twisting, buckling, or sagging under heavy loads.

The main beams are mounted on end trucks, which move along rails on the bridge runway. The end trucks are powered (in powered cranes) and support the weight of the crane as it moves along the track.

In short, the main beam of a double beam bridge crane is essential for carrying and distributing the weight of both the crane's components and the loads it is designed to move. Proper design and construction of the main beams are crucial for the crane's safety and operational efficiency.

 

Lifting System

Motor: The motor of a lifting system in a double beam bridge crane is central to its ability to safely lift and lower heavy loads. It needs to be robust, reliable, and properly matched to the crane's specifications to ensure efficient and safe operation. Proper maintenance and regular inspection of the motor and associated components are essential to prevent failures and extend the crane's operational life.

2) Reducer: A Reducer (also called a gearbox or speed reducer) in the lifting system of a double beam bridge crane is a crucial component that reduces the motor's speed and increases the torque, enabling the crane to lift heavy loads safely and efficiently.

3) Drum: The drum of the lifting system in a double beam bridge crane (also called a double girder overhead crane) is a crucial component that plays a key role in the hoisting mechanism. It is part of the lifting system, which is responsible for lifting and lowering the load by winding and unwinding a wire rope or chain.

4) Wire rope: The wire rope used in the lifting system of a double beam bridge crane plays a critical role in supporting the loads during lifting and lowering operations. It needs to be strong, durable, and capable of withstanding the stresses associated with frequent use and heavy lifting.

5) Pulley block: A pulley block in a lifting system, particularly for a double beam bridge crane, is an essential component that facilitates the lifting and lowering of heavy loads by using a combination of pulleys, ropes, and mechanical advantages.

6) Lifting device: The lifting device in a double beam bridge crane is the component responsible for raising and lowering the load. It plays a central role in the overall operation of the crane.

3.End carriage

1) The end carriage of a double beam bridge crane is a key component in the crane's structural system. It typically consists of two main parts: the end carriage frame and the wheels that allow the crane to travel along the bridge beams.

2) The end carriage supports the bridge beams at either end and provides the necessary movement to transport the load across the crane's span. It also houses the drive mechanism for movement along the runway beams.

3) End Carriage Frame: The frame is a rigid structure designed to hold the crane's wheels, motors, and other components. It is made from strong steel to support heavy loads and resist wear and tear over time.The end carriages help distribute the load evenly across the crane's structure.They allow the crane to move across the span of the building or workspace, providing flexibility in operation.Properly designed end carriages help ensure the crane moves smoothly and safely, preventing issues like derailment or misalignment.

 

4.Crane travelling mechanism

1) Working principle

The crane travelling mechanism of a double beam bridge crane typically operates with a motor-driven trolley and track system. The beams (usually two parallel girders) are mounted on end trucks that run along rails on the crane runway. The motor drives the trolley along the bridge's length, allowing the crane to move horizontally. The movement is controlled by a series of gears, brakes, and electrical systems, enabling precise positioning of the load across the crane's span.

2) Functions of the crane operating mechanism

Movement along the runway:The traveling mechanism allows the entire crane (including the bridge structure and hoist) to move horizontally along the runway beams. This horizontal movement is typically powered by electric motors, which drive wheels or bogies that are mounted on the bridge's structure.

Load transportation:The mechanism supports and moves heavy loads horizontally across the workshop or factory, allowing the operator to position the load at various points within the crane's operational area.

Alignment and precision movement:The traveling mechanism ensures the crane moves along the correct path, maintaining the alignment of the bridge with respect to the runway. This is essential for precise load handling and positioning. The mechanism is designed to minimize wear and tear, reduce friction, and ensure smooth operation even under heavy loads.

 

5.Trolley travelling mechanism

1) Structural composition

Trolley Frame

The frame is the main structural support for the trolley. It houses and supports other components such as the hoist, wheels, and other mechanisms.

It is made of high-strength steel to ensure durability and stability under heavy loads.

The frame is designed to be rigid and resistant to deformation during operation.

Traveling Wheels

The traveling wheels are mounted on the trolley and run on the bridge beams. They ensure smooth movement along the length of the bridge.

These wheels are usually made of steel or alloy material for durability and wear resistance.

The wheels are designed with flanges to keep them aligned with the bridge rails or tracks, ensuring the trolley moves without deviation.

Wheel Axles

The wheel axles are the shafts that connect the wheels to the trolley frame, allowing the wheels to rotate.

Axles are typically made of high-strength materials like carbon steel to support the weight of the load and resist wear.

Trolley Drive Motor and Gearbox

The trolley is powered by a drive motor, typically an electric motor, connected to a gearbox that reduces the speed and increases the torque.

The motor provides the necessary power to move the trolley along the bridge beams.

Gearboxes are designed to transmit the motor's power to the wheels efficiently and smoothly.

Trolley Rail and Guide System

The trolley runs on a pair of rails or tracks mounted on the bridge girders. These rails are precisely aligned to ensure smooth travel.

Guide rollers or guide wheels are often installed to prevent lateral movement or deviation from the rail path, ensuring accurate positioning.

Electromagnetic or Mechanical Braking System

A braking system is necessary to stop the trolley at a precise location when needed.

Brakes may be electromagnetic, mechanical, or hydraulic in design, depending on the requirements of the crane system.

The braking system ensures the trolley is securely stopped when the load is positioned.

Trolley End Stops

End stops are used to prevent the trolley from moving beyond the designated travel limits.

They are usually placed at both ends of the trolley track and are designed to absorb the impact when the trolley reaches its maximum travel position.

Control System

The trolley is controlled by an electrical or wireless control system that allows the operator to move the trolley along the bridge.

The system may include limit switches, sensors, and position encoders to monitor the position of the trolley and ensure safe operation.

2) Function of the trolley operating mechanism

Horizontal Movement of the Trolley: The primary function of the trolley travelling mechanism is to move the hoisting trolley horizontally along the crane bridge. This allows the hoisting mechanism (the hook, lift, or other attachments) to cover a large working area along the bridge span.

Support and Stability: The mechanism provides support to the hoist and ensures that the trolley remains stable during its movement. This includes maintaining the balance of the hoisting load as the trolley moves along the beam.

Positioning and Precise Movement: It enables precise positioning of the trolley at any point along the span of the bridge. This is critical for accurate lifting and placing of heavy loads, as well as for maintaining safety during operation.

Drive Mechanism for Movement: The trolley travelling mechanism is driven by motors (usually electric), which are responsible for providing the necessary force to move the trolley. These motors are typically integrated with a system of gears, pulleys, or rails.

Speed Control: The trolley travelling mechanism often includes systems that regulate the speed at which the trolley moves, allowing operators to adjust the pace of the crane's operations based on the load, task, or environment.

Energy Efficiency: In modern designs, the trolley travelling mechanism is often designed with energy-efficient technologies, including regenerative drives that can recapture energy when the trolley slows down or brakes.

Automatic/Manual Control: The mechanism can be operated via manual controls or automated systems. In more advanced systems, the trolley can be programmed for automated travel along the bridge, improving operational efficiency and reducing human error.

Safety Mechanisms: It includes safety features like limit switches, overload protection, and emergency stop systems to ensure safe operation of the crane and prevent damage to the structure, hoist, or load.

Alignment and Synchronization: In some double-beam crane systems, the trolley travelling mechanism is synchronized with the movement of other components (e.g., the hoist or bridge) to ensure smooth operation and accurate coordination between lifting and moving the load.

 

6.Crane wheel

1) Function of wheels

Movement: The wheels enable the crane to move horizontally across the bridge's runway, allowing the load to be positioned as needed.

Support: They help support the weight of the crane and the load it is carrying, transferring this weight to the crane track or runway.

2) Design requirements

Material: The crane wheel is usually made from high-strength steel or cast iron to withstand the heavy loads and the wear caused by continuous movement.

Shape: Typically, the wheel has a V-shaped or grooved profile to fit into the track (rail) of the crane runway. This design helps maintain stability and reduce slipping.

Diameter: The size of the wheels depends on the weight of the crane, the load it handles, and the dimensions of the crane track. Larger wheels are used for heavier loads.

7.Crane Hook

1)Functionality:

Lifting: The crane hook is used to attach to the load to be lifted. It can move along the bridge crane's beams, controlled by the hoist, to position the load.

Securing the Load: The hook secures the load during lifting, ensuring stability and safety.

Load Rotation and Alignment: Some crane hooks come with swivels, allowing the load to rotate as the crane moves. This feature is useful for aligning loads or rotating them during the lift.

2)Types of Crane Hooks:

Single Hook: Typically used for smaller, less complicated lifts.

Double Hook: Used for heavier, more balanced lifting, often seen in double-beam bridge cranes.

Crane Hook Blocks: A combination of the hook and the sheave assembly used in hoisting and lowering.

Motor

A double beam bridge crane typically uses an electric motor for the operation of its hoisting, trolley, and bridge movements.

2) Hoisting Motor: This motor is responsible for raising and lowering the load. It's typically a DC motor or AC motor, depending on the design and application. DC motors offer better speed control and high torque at low speeds, while AC motors are simpler and more durable in many industrial settings.Trolley Motor: This motor moves the hoist along the bridge girder. It is often an AC motor, sometimes with a frequency inverter to control the speed of the trolley movement.Bridge Motor: This motor moves the entire crane bridge along the rails. Like the trolley motor, it's typically an AC motor that can be fitted with a variable frequency drive (VFD) for controlling speed and ensuring smooth motion.

3)The power supply to these motors is often 3-phase AC, but can vary depending on the crane's size and location. The motor's power rating will depend on the crane's capacity, with larger cranes needing higher-rated motors.

Sound and light alarm system & limit switch

1) Sound and light alarm system

Sound Alarm:Typically a loud horn, siren, or buzzer that produces a sound in the event of an emergency, malfunction, or when certain parameters are exceeded (e.g., load limits, mechanical failure, or over-speed).Common frequencies range from 90 dB to 120 dB to ensure audibility over environmental noise.Can be triggered by various conditions like:

Crane overload.

Power failure or electrical malfunction.

Emergency stop activation.

Maintenance or inspection alerts.

Light Alarm:A set of warning lights that flash or stay on to visually signal an issue or condition.The light colors generally used are:

Red: for critical alerts or faults (e.g., overload, malfunction).

Yellow/Orange: for warnings or less critical issues (e.g., maintenance alert).

Green: for operational readiness or normal functioning.

2) Limit switch

A limit switch in a double beam bridge crane is a safety device used to control the movement of the crane's hoist, trolley, or bridge. It serves to limit the travel of the crane to a predetermined position, ensuring that the crane does not exceed its safe operating range.

Purpose of Limit Switches in Double Beam Bridge Cranes: End of Travel Protection: Limit switches are installed at the ends of the travel path to prevent the crane from moving beyond its designated travel limits, preventing mechanical damage to the crane or the structure.

Overload Prevention: In some cases, limit switches can help prevent overloads by cutting off the crane's power when it reaches certain thresholds.

Types of Limit Switches:

Mechanical Limit Switches: These are activated by physical contact with a part of the crane, such as the hoist or trolley. When the crane reaches the end of its track or other defined position, the switch is triggered to stop further movement.

Electronic Limit Switches: These use sensors, such as proximity sensors or optical sensors, to detect the position of the crane. They are more precise and can be integrated with the crane's control system for more complex operations.

Rotary Limit Switches: Used to detect the angular position of rotating parts, these are commonly used in cranes to limit the rotation of the hoist drum or other rotating components.
