Main beam

1)The main beam of a Bridge Crane Beam is the core load-bearing structure of the entire crane, playing a key role in supporting the lifting mechanism, carrying materials and moving them along the track. The design and manufacture of the main beam have a direct impact on the performance, stability and safety of the crane.

2)The main beam is the main load-bearing component of the crane, directly bearing the weight of the lifting mechanism and the hoisted load. It must have sufficient strength and rigidity to ensure that no excessive deformation or distortion occurs during the load-bearing process. The main beam usually adopts an I-beam or box beam structure. Depending on the lifting capacity and span, the structural design of the main beam will also be different. I-beam beams are suitable for cranes with smaller lifting capacity and shorter spans, usually with lower costs and simple structures. Box beams are suitable for cranes with larger lifting capacity and longer spans. Compared with I-beam beams, box beams have higher strength and rigidity and can withstand greater loads and torques.

3)The main beam is usually welded from high-strength steel plates to ensure that it does not break or deform excessively under high loads. The selection of materials must be strictly calculated and tested to ensure safety and durability. The length of the main beam depends on the span (span) of the crane, usually ranging from 7.5 meters to 31.5 meters. The height, width and thickness of the main beam are designed according to the lifting capacity and span to ensure its load-bearing capacity.

Lifting System

1) Efficient and stable: Through the cooperation of electric hoists and related components, the lifting system can quickly and smoothly lift and lower heavy objects.

2) High safety: The lifting system is equipped with multiple safety protection devices, such as limit switches, overload protection, brake devices, etc., which can stop the operation in time when an abnormality occurs to prevent accidents.

3) Easy operation: The control of the lifting system is usually achieved through an electrical control box or a remote control. The operator can control the lifting and operation of the crane on the ground or remotely, which is convenient and fast.

4) Easy maintenance: The design of the main components such as electric hoists and wire ropes is relatively simple, and it is also convenient to repair and replace parts. Daily maintenance such as lubrication and checking the wear of wire ropes is also relatively easy.

 

3.End carriage

1) The end beam of a Bridge Crane Beam is an indispensable part of its structure, responsible for supporting the main beam and running on the longitudinal track of the crane. The end beam ensures that the crane can move smoothly on the track through a close connection with the main beam and the operating mechanism, thereby realizing the lateral and longitudinal handling of materials.

2) The main function of the end beam is to support the main beam of the Bridge Crane Beam and ensure that the main beam can run stably on the track. The end beam is usually rigidly connected to the main beam to form an integral structure. The end beam is equipped with a running mechanism, including motors, wheel sets and other components. Driven by the motor, the end beam moves along the longitudinal track, thereby driving the entire crane to move longitudinally in the factory or workshop.

3) The end beam is closely matched with the track through the wheels at both ends, which not only provides longitudinal movement, but also provides lateral stability for the entire crane to prevent lateral displacement or shaking during the operation of the crane. The end beam is usually welded with high-strength steel or processed with steel plates. The structure is strong and durable and can withstand dynamic loads during the operation of the crane. The length of the end beam depends on the width of the crane's track and it needs to be designed to ensure a tight fit with the track while also being strong enough to support the weight of the main beam and hoisting system.

 

4.Crane travelling mechanism

1) Smooth operation: Through the cooperation of the reducer and the brake, the crane running mechanism can ensure the stability of the crane during movement and reduce vibration and impact.

2) High efficiency and energy saving: With the use of high-efficiency motors and variable frequency speed regulation technology, the crane running mechanism can flexibly adjust the speed according to the workload while maintaining strong power output, reducing unnecessary energy consumption.

3) Precise positioning: The crane running mechanism can achieve precise control of the crane through the electrical control system and brakes, ensuring that it can stop accurately when moving to the predetermined position, which is convenient for lifting operations.

4) Strong adaptability: The crane running mechanism is suitable for a variety of environments. Whether it is in the narrow space in the factory or in the open air, it can achieve smooth operation through the flexible cooperation of the motor and the wheel group.

5) High safety: The crane running mechanism is equipped with multiple safety protection measures such as overload protection, limit devices, buffers, etc., which can prevent accidents caused by operating errors or equipment failures.

5.Trolley travelling mechanism

Maintenance and care of the trolley running mechanism:

1) Lubrication and maintenance: The wheel group, reducer and other moving parts of the trolley need to be regularly filled with lubricating oil to ensure the smoothness of each moving part during operation and reduce wear.

2) Wheel inspection: Regularly check the wear of the trolley wheels to ensure good contact between the wheels and the track. If the wheels are found to be severely worn or deformed, they should be replaced in time.

3) Track cleaning: Keep the main beam track clean to prevent foreign objects from getting stuck in the trolley wheels and affecting the normal operation of the trolley.

4) Electrical system inspection: Regularly check the electrical control system of the trolley running mechanism, including motors, inverters, limit switches, etc., to ensure that the electrical equipment operates normally.

5) Tightening bolts: Since the trolley may be affected by vibration during operation, regularly check and tighten the connecting parts between the trolley and the main beam to prevent equipment failures caused by looseness.

6.Crane wheel

Functions of wheels:

1) Load-bearing: The wheels are responsible for bearing the weight of the crane and the weight of the cargo being hoisted. They need to have sufficient strength and durability to withstand the static and dynamic loads generated by the crane during operation.

2) Driving operation: The wheels are driven by an electric motor or drive system and move longitudinally (trolley operation) or laterally (trolley operation) along the track. The driving wheels achieve smooth driving through friction with the track.

3) Guidance: The design of the wheels ensures that the crane does not deviate from the track and always moves along the predetermined route. The wheels usually fit tightly with the track to avoid lateral slippage or derailment.

7.Crane Hook

Hook usage and operation specifications:

1) Correct mounting: When using the hook, the operator must ensure that the heavy object is firmly mounted on the hook to avoid the situation where the sling or sling is not fully inserted into the hook, and prevent the heavy object from falling off during the lifting process.

2) Avoid overloading: The use of the hook must comply with its rated load limit, and overloading is prohibited. Overloading operation will cause the hook to be permanently deformed or even broken, posing a serious safety hazard.

3) Regular inspection: The hook is prone to wear, cracks, deformation and other problems during long-term use, so it needs to be inspected regularly. Any abnormal situation (such as deformation, cracks, and failure of the safety lock) needs to be repaired or replaced immediately.

4) Prevent lateral force: The hook is designed to withstand vertical force, not lateral force. Therefore, lateral force should be avoided as much as possible when using the hook, otherwise it may cause damage or deformation of the hook.

5) Correct use of the safety lock: During lifting operations, the safety lock must always be in a closed state to prevent the sling or ring from accidentally slipping out. The operator needs to check whether the lock is working properly before mounting and lifting.

Motor

Functions of the motor:

1) Providing power: The motor is the main power source of the crane, which drives gears, wire ropes or chains to lift the hook or move the trolley or truck.

2) Adjusting speed: The motor can adjust the lifting speed and moving speed of the crane through a frequency conversion control system or other speed regulating devices to ensure stable operation under different working conditions.

3) Ensuring stability and safety: The motor ensures that the crane can stop quickly and stably through the brake system to prevent the heavy objects from sliding down or the crane from losing control.

.

Sound and light alarm system & limit switch

1) The sound and light alarm system is used in Bridge Crane Beam to remind operators and surrounding personnel to pay attention to the operating status of the crane, especially to provide warning signals when the crane is started, moved or encounters dangerous situations.

Safety warning: When the crane starts to operate, lifts heavy objects or approaches the operating range, the sound and light alarm system will sound an alarm to remind on-site staff to pay attention to avoid collisions or dangers.

Fault alarm: When the crane system fails or reaches the set limit conditions (such as overload or limit switch triggering), the sound and light alarm system will send an alarm signal to prompt the operator to stop the operation immediately and check the equipment.

Operation reminder: When the crane is running or turning, the alarm system reminds the surrounding personnel through sound and light to prevent accidental entry into the working area of ​​the crane.

2) The limit switch is an important safety device in Bridge Crane Beam. It is mainly used to limit the operating range of the crane or trolley to prevent the crane from exceeding the safe area or the hook from over-operating, causing equipment damage or safety accidents.

Travel limit: The limit switch automatically triggers a stop signal when the crane or hook reaches the end of the travel by setting the maximum travel of the crane or trolley to prevent the equipment from continuing to operate and causing danger.

Prevent over-hoisting: During the lifting process, the limit switch can limit the highest position of the hook to prevent the hook from over-lifting or the wire rope from over-hoisting, thereby avoiding damage to the equipment or accidents.

Avoid collision: When the crane or trolley approaches the travel limit, the limit switch will trigger the brake to prevent the crane or trolley from colliding with surrounding objects or walls.

10.Safety Devices

1) Limit switch: used to limit the travel of the crane and trolley to prevent it from exceeding the set safety range.

2) Overload protection device: monitor the load of the crane to prevent overload operation. Real-time monitoring of the weight of the hoisted load, when it exceeds the rated load, an alarm is issued and the power is automatically cut off to stop the crane operation.

3) Sound and light alarm system: when the crane starts, stops or fails, it sends out sound and light signals to remind the operator and surrounding personnel to pay attention to safety. It can effectively reduce misoperation and accidents.

4) Emergency stop button: in an emergency, the power can be cut off immediately to stop all operations of the crane. Usually there are multiple emergency stop buttons to facilitate the operator to respond quickly at different positions.

5) Braking system: ensure that the crane can brake quickly and reliably when it stops to prevent the heavy objects from sliding down or the equipment from getting out of control.

6) Safety locking device: during equipment maintenance or overhaul, ensure that the equipment is in a safe state to prevent accidental start-up.

11.Control Mode

1) Manual control: The operator directly controls the operation of the crane through a handle, button or joystick. The manual control system has a simple structure and is easy to operate, suitable for small or simple working environments. The operator can flexibly adjust the operation of the crane according to the on-site conditions.

2) Wireless remote control: The operator can control the operation of the crane from a long distance through a wireless remote control. The operator can stay away from dangerous areas to improve the safety of the operation. The operator can move freely on site to facilitate observation of the operation.

3) Suspension control: The control box is suspended near the crane by a cable, and the operator can operate on the control box at any time. The operator does not need to approach the crane and can control it at a safe distance. The relatively fixed control position can reduce interference during operation.

4) Automatic control: The programmable logic controller (PLC) system is used to automatically control the operation of the crane. It can realize complex control logic and procedures and improve work efficiency. The PLC system can monitor the equipment status in real time and automatically adjust the operation.

5) Hybrid control: Combine manual, wireless, suspension and automatic control to form a comprehensive control solution. Select the appropriate control method according to different working conditions to improve work efficiency and safety. It can flexibly adjust the control method according to changes in the on-site environment.
