Industrial Crane FAQ

Start with the rated load, span or working radius, lifting height, operating frequency, material characteristics, available headroom, and indoor or outdoor conditions. Workshop drawings and a description of the handling process allow our engineers to compare overhead cranes, gantry cranes, jib cranes, and hoist systems for your site.

Please provide the required capacity, span, lifting height, duty cycle, lifting and travel speeds, control method, power supply, operating environment, installation location, destination port, and site drawings when available. For special loads, also include the load dimensions, center of gravity, temperature, dust, corrosion, or hazardous-area requirements.

Single girder overhead cranes are usually suitable for light and medium-duty handling where lower dead weight and installation cost are priorities. Double girder cranes provide higher capacity, greater rigidity, wider spans, higher duty classifications, and more room for maintenance platforms or specialized trolleys.

A gantry crane is often preferred for outdoor yards, precast plants, ports, construction sites, or facilities without a suitable runway structure. An overhead crane is generally more space-efficient inside a workshop when the building can support runway beams and crane wheel loads.

A low-headroom or European-style overhead crane can reduce the distance between the hook and roof. The final design may use compact end carriages, an optimized girder connection, or a low-headroom hoist, but the building clearances and runway elevation must be checked before selection.

Duty class is selected from the expected load spectrum, lifts per hour, daily operating time, travel distance, and percentage of lifts near rated capacity. A crane used occasionally for maintenance requires a different duty group from a production crane operating continuously in a steel mill or port.

The rated capacity must cover the maximum lifted load plus below-the-hook devices such as grabs, magnets, lifting beams, or spreaders. Capacity should not be selected by adding an arbitrary margin; the actual load cases, attachments, and applicable design standard should be reviewed by an engineer.

Yes. Our engineering team can review building width, runway elevation, column spacing, roof clearance, maintenance access, power supply, and load path. The review helps identify clearance conflicts and confirms the preliminary crane span, lifting height, and installation arrangement.
