Custom Crane: How to Get Your Custom Overhead Crane?
An Overhead Crane is a type of lifting equipment typically used in manufacturing, construction, warehousing, and other industries where heavy loads need to be moved efficiently. So, having a proper custom overhead crane designed for specific needs is crucial for your industry.
The Classification of Overhead Cranes
- Classified by structure: such as single-girder overhead crane, double-girder overhead crane, underslung overhead crane, double-trolley bridge crane, multiple-trolley bridge crane, etc.
- Classified by lifting device: such as hook overhead crane, grab overhead crane, electromagnetic overhead crane, container overhead crane, etc.
- Classified by purpose: such as workstation overhead crane, general-purpose overhead crane, metallurgical overhead crane, explosion-proof overhead crane, etc.
Key Components of Overhead Cranes
Overhead cranes consist of several essential components that work together to facilitate smooth and reliable material handling. The key components include:
- Bridge: The bridge is the main horizontal beam that spans the width of the facility. It supports the hoist and facilitates the movement of the loads.
- Lifting Device: The lifting device is responsible for lifting and lowering the loads, such as a hoist. It is attached to the bridge and moves along it, allowing for precise positioning of the loads.
- End Trucks: End trucks are located at either end of the bridge and run on rails. They support the bridge structure and provide stability during crane movements.
- Controls: The controls enable the operator to maneuver the crane and control the lifting, lowering, and movement of loads. Modern cranes often utilize advanced control systems for enhanced precision and safety.

How to Design an Overhead Crane?
Here is a general overview of designing an overhead crane:
Determine Overhead Crane Parameters
- Lifting capacity: It refers to the mass of the weight being lifted. The unit is kg or t. Calculate the maximum weight the crane needs to lift.
- Lifting height: It refers to the distance between the hook center and the ground.
- Overhead crane span: It refers to the distance between the two track centerlines of the overhead crane running track is called the span of the crane.
- Working level: The working condition is the index of the whole machine, indicating the full load degree of the crane lifting load and the times of lifting work. The working level of the crane is divided into 8 levels, A1-A8, from light grade(A1-A3) to extra heavy grade(A8).
Besides, you should identify the working environment. Consider factors like temperature, humidity, and presence of hazardous materials.
Design the structure:
- Calculate the size and strength of the crane components such as the girders, columns, and runway beams.
- Consider factors like material strength, fatigue resistance, and safety factors.
- Consult relevant design codes and standards, such as CMAA (Crane Manufacturers Association of America) or local regulations.
Determine the lifting mechanism:
- Choose an appropriate hoist system (electric wire rope hoist, chain hoist, etc.) based on the load requirements.
- Calculate the required lifting speed, acceleration, and deceleration.
- Consider safety features like limit switches, emergency stop buttons, and overload protection devices.

Select the control system:
- Decide between manual, semi-automated, or fully automated control systems.
- Consider the operator’s interface, safety features, and integration with other equipment.

Consider electrical and power requirements:
- Determine the power supply (voltage, frequency) and the type of power delivery (cable reel, festoon system, conductor bar).
- Calculate the electrical load and specify the necessary electrical components (motor, controller, cables, etc.).
Evaluate safety features:
- Include safety measures like limit switches, emergency stop buttons, overload protection devices, and safety barriers.
- Consider personnel safety during crane operation and maintenance.
Perform structural analysis:
- Use engineering software to analyze the crane structure and ensure it can withstand the expected loads and forces.
- Verify the stability, stress distribution, and deflection of critical components.
Create detailed drawings:
- Prepare detailed manufacturing and assembly drawings, including all necessary dimensions and specifications.
- Include assembly sequences, welding details, and material specifications.
Prototype and testing:
- Build a prototype of the crane and conduct thorough testing to verify its performance, functionality, and safety.
- Make any necessary adjustments or improvements based on the test results.
It’s important to note that designing an overhead crane requires expertise in structural engineering, mechanical engineering, and electrical engineering. Consider consulting with qualified professionals or crane manufacturers for a safe and efficient design. After figuring out these steps, you shall customize your own overhead crane.
