· Load Capacity: Determine the maximum weight the crane needs to lift. Double girder top running cranes are ideal for handling heavy loads, often ranging from 20 to 500 tons or more. Ensure the crane’s capacity exceeds the maximum load to provide a safety margin.

　　· Span: Measure the distance between the crane’s runway beams. This span will determine the crane’s coverage area. Double girder bridge cranes can handle wider spans compared to single girder overhead cranes, making them suitable for larger workspaces.

　　· Lifting Height: Consider the height from the ground to the highest point the crane needs to lift. This includes the distance between the crane’s hook and the load’s lifting point.

　　· Operating Environment: Evaluate the environmental conditions where the crane will be used. For example, if the crane operates in a high-temperature environment, a high humidity area, or a corrosive environment, you may need specialized materials or protective coatings.

　　This refers to how frequently the crane will be used. Cranes are categorized based on their duty cycles, such as light duty overhead crane, medium duty overhead crane, or heavy duty overhead crane. Choose a crane with a duty cycle rating that matches your operational demands.

　　· Pendant Control: Offers a simple and cost-effective way to control the crane from the ground.

　　· Radio Remote Control: Provides greater flexibility and allows the operator to control the crane from a distance, enhancing safety and convenience.

　　· Cab Control: Ideal for larger overhead cranes or complex operations, providing a comprehensive control system with visibility and operator comfort.

　　· Anti-Sway Mechanism: Helps to stabilize the load and reduce swaying during lifting and travel, which is crucial for precision and safety.

　　· Overload Protection: Prevents the crane from lifting loads that exceed its capacity, protecting both the crane and the load.

　　· Emergency Stop: An essential feature for halting crane operations immediately in case of an emergency.
