Monorail Overhead Crane

1.Bridge

The bridge is the main structure of the crane that spans the width of the work area. It supports the trolley and hoist and moves along the runway rails. The bridge can be:

Single-Girder: A single beam structure, generally used for lighter loads or shorter spans.

Double-Girder: A stronger structure with two parallel girders, used for heavier loads and higher lifting heights.

Trolley

The trolley moves along the length of the bridge and carries the hoist. It allows horizontal movement of the load across the crane's span. The trolley is either top-running (on top of the bridge girders) or under-running (beneath the girders).

Hoist

The hoist is the component responsible for lifting and lowering the load. It consists of a motor, drum, wire rope or chain, and a hook. The hoist can be wire-rope or chain-based, depending on the application and load capacity:

Wire Rope Hoist: Ideal for heavy-duty applications with higher lifting speeds and capacities.

Chain Hoist: Typically used for lighter loads.

 

3.End carriage

1) The end beam is located at both ends of the main beam of the single beam bridge crane and is an important component connecting the main beam and the walking mechanism. The end beam not only supports the main beam, but also allows the crane to move on the track through its wheels. The main function of the end beam is to support the main beam and bear the load generated by the lifting object. Meanwhile, the wheels on the end beam are responsible for the lateral movement of the crane, enabling the entire equipment to cover a larger working area.

2) The end beam is usually formed by welding U-shaped channel steel formed by rolling steel plates, which ensures sufficient strength and is easy to install and maintain. In the design of end beams, the connection method with the main beam, such as bolt connection or welding, is usually considered. The manufacturing process of end beams includes multiple steps such as cutting, forming, and welding. Accurate processing and high-quality welding are key factors in ensuring the performance of end beams. The quality of the weld seam directly affects the overall strength and service life of the end beam.

3) Each crane must be clearly labeled with its rated lifting capacity to ensure that the operator understands its carrying capacity. During work, no one is allowed on the bridge or using hooks to transport people, in order to prevent accidents from occurring. No one is allowed to drive the crane without an operating license or under the influence of alcohol, to ensure the safety awareness and reaction ability of the operators.

 

4.Crane travelling mechanism

1) The driving mode of the large vehicle operating mechanism is mainly divided into two forms: centralized driving and separate driving. Centralized drive is driven by an electric motor through a transmission shaft to move the wheels on both sides, while separate drive is driven by two motors of the same specifications through couplings and reducers to drive the wheels of the large vehicle. The large vehicle operating mechanism must be equipped with brakes to ensure safe parking within the allowable braking range after power failure. When the sliding distance of the large vehicle exceeds the specified value after power failure during normal operation, the brake should be adjusted immediately to ensure that its braking meets the requirements.

2) The large vehicle should be equipped with a terminal to form a limit device, and corresponding limit device safety touch gauges should be installed at the two terminals of the large vehicle travel to ensure that the limit device rotating arm is touched and the normally closed contact is opened before the large vehicle reaches the end of the track to cut off power and stop the vehicle; Corresponding limit safety contact gauges should be installed between two cranes on the same track. When two vehicles collide, they should touch each other's limit switch arm and open the contact to cut off power, in order to prevent the collision of the two vehicles.

3) The four corners of the bridge frame of the overhead crane must be equipped with spring or hydraulic buffers, and metal frame type stoppers with hardwood or rubber pads must be installed at the end of each track of the crane. This can prevent the crane from derailing, absorb the kinetic energy of the crane's movement, buffer and reduce vibration, and protect the building of the crane from damage.

5.Trolley travelling mechanism

1) Basic concept: The running mechanism of a small car is usually composed of an electric motor, a reducer, a transmission shaft, wheels, etc. Through the collaborative work of these components, the smooth movement and precise positioning of the small car are achieved.

2) Main function: The main function of the trolley operating mechanism is to support the cargo and enable it to move laterally on the main beam, thereby meeting the lifting requirements at different positions. At the same time, it also undertakes the task of partial load transmission, transferring the weight of the goods to the main beam through the trolley.

3) Design features: The design of the trolley operating mechanism needs to consider various factors, such as load capacity, operating speed, track conditions, etc. In order to ensure the smooth operation and safety of the car, high-quality materials and advanced manufacturing processes are usually used.

4) Safety precautions: When using the trolley operating mechanism, special attention should be paid to safety precautions. For example, the fastening and wear of each component should be checked regularly to ensure the reliability and effectiveness of the brake; During the operation, it is necessary to avoid violations such as overloading and diagonal pulling and lifting; Suspend use in adverse weather conditions, etc.

The design and manufacturing quality of the wheels directly affect the operational stability and safety of the crane.

2) The main function of the wheels is to support the weight of the crane and enable it to move smoothly on the track. At the same time, the wheels also need to withstand various forces from the crane, such as vertical loads, horizontal loads, and impact loads. Therefore, the wheels need to have sufficient strength and wear resistance to ensure their long-term stable operation.

3) The design of wheels needs to consider various factors, such as load capacity, operating speed, track conditions, etc. Generally speaking, the larger the diameter of the wheel, the better its load-bearing capacity and operational stability. However, the diameter of the wheels should not be too large, otherwise it will increase the height and cost of the crane. In addition, the material and manufacturing process of the wheels can also affect their performance and lifespan.

7.Crane Hook

1) Hooks are usually made of high-quality steel with sufficient strength and wear resistance to ensure they can withstand the weight of goods and remain stable during lifting. The design and manufacturing quality of the hook directly affect the efficiency and safety of the crane.

2) The main function of the hook is to connect the crane and the cargo, allowing the cargo to be lifted and transported vertically. At the same time, the hook also needs to withstand various forces from the cargo, such as gravity, inertia, and wind force. Therefore, the hook needs to have sufficient strength and stability to ensure that it will not break or deform during the lifting process.

3) The design of the hook needs to consider multiple factors, such as load capacity, cargo type, working environment, etc. Generally speaking, the shape and size of the hook will be customized according to the characteristics and requirements of the goods. For example, for some heavy goods, larger sized hooks may be required; For some light goods, smaller sized hooks can be used. In addition, the material and manufacturing process of the hook can also affect its performance and lifespan.

4) When using a hook, some safety precautions need to be taken into account. For example, the wear and crack condition of the hook should be checked regularly to ensure its normal operation; During the operation, it is necessary to avoid violations such as overloading and diagonal pulling and lifting; Suspend use in adverse weather conditions, etc.

Motor

1) An electric motor is a device that converts electrical energy into mechanical energy, typically consisting of a stator, rotor, and bearings. In a single beam bridge crane, the electric motor is connected to various operating mechanisms of the crane through a reducer and transmission shaft to provide power.

2) The main function of the electric motor is to provide power for the crane and drive its various operating mechanisms to work. Meanwhile, the electric motor can also adjust the operating speed and direction of the crane as needed to meet different lifting requirements.

3) The design of an electric motor needs to consider various factors, such as load capacity, operating speed, working environment, etc. Generally speaking, the power and speed of the electric motor will be customized according to the needs of the crane. In addition, the material and manufacturing process of the electric motor can also affect its performance and lifespan.

4) In order to extend the service life of the electric motor and ensure its normal operation, regular maintenance work is required. This includes cleaning, lubricating, tightening, and adjusting the motor, as well as timely replacement of damaged components.

.

Sound and light alarm system & limit switch

1) The sound and light alarm system is a safety device that can emit sound and light signals, usually consisting of a buzzer, flash, and control circuit. In Monorail Overhead Crane, the sound and light alarm system is used to remind operators to pay attention to the operating status and abnormal situations of the crane. The main function of the sound and light alarm system is to issue an alarm signal when the crane encounters abnormal situations, reminding operators to take timely measures to avoid accidents. At the same time, limit switches can restrict the operating range of the crane, preventing it from exceeding the predetermined area and causing dangerous situations such as collisions or falls.

3) The design of sound and light alarm system needs to consider various factors, such as alarm volume, light brightness, control circuit, etc. Generally speaking, the alarm volume and light brightness need to be large enough to ensure that they can attract the attention of operators; The control circuit needs to have high sensitivity and good reliability to ensure the accuracy and timeliness of the alarm signal. The design of limit switches needs to consider factors such as sensitivity, accuracy, and installation position to meet the needs of different occasions.

4) Regular maintenance and upkeep are necessary to extend the service life of the equipment and ensure its normal operation. This includes cleaning, lubricating, tightening, and adjusting the equipment, as well as timely replacement of damaged parts. At the same time, attention should be paid to the storage environment of the equipment to avoid being affected by factors such as humidity, high temperature, or corrosive gases.

10.Safety Devices
