The delivery time for a custom-made gantry crane varies between 12 and 24 weeks, depending on the design complexity and specific requirements. Simple single-girder gantry cranes typically have shorter lead times than complex double-girder gantry cranes or mobile gantry cranes. The total time includes design, engineering, production, and assembly. This timing is crucial for project planning and operational continuity.
What determines the delivery time of a custom-made gantry crane?
The delivery time is influenced by design complexity, material availability, workshop capacity, and specific customer requirements. Standard single-girder gantry cranes have shorter lead times than specialized configurations with unique lifting capacities or movement capabilities.
Design complexity plays a major role in planning. Simple gantry cranes with standard dimensions and lifting capacities up to 10 tons can be realized faster. Complex double-girder gantry cranes with lifting capacities above 50 tons require extensive engineering and longer production times.
Material availability significantly affects planning. Standard steel profiles are usually immediately available, while specialized components such as high-quality hoists, frequency converters, or special wheels may have longer delivery times. Seasonal influences and market conditions also play a role here.
Workshop capacity determines when production can start. Busy periods, such as spring when many construction projects start up, can affect planning. Semi-gantry cranes and mobile gantry cranes often require specific production scheduling due to their unique construction requirements.
How long does the design process take for a custom gantry crane?
The design process takes 4 to 8 weeks, from initial consultation to final approved drawings. This phase includes technical calculations, 3D modeling, construction drawings, and all necessary engineering documentation for safe realization.
The initial consultation phase usually takes 1-2 weeks. Specific requirements are discussed, such as lifting capacity, span width, lifting height, and operational conditions. For gantry cranes, foundation requirements and possible rail systems are also defined.
Engineering and calculations take 2-4 weeks. Structural calculations for load-bearing structure, stability, and safety are performed. For double-girder gantry cranes, these calculations are more complex than for single-girder variants. Mobile gantry cranes require additional calculations for stability during movement.
Drawing and documentation complete the design phase in 1-2 weeks. Final construction drawings, electrical diagrams, and assembly instructions are prepared. Approval procedures and any adjustments are included. Complex projects may require additional engineering time.
What steps follow after design approval?
After design approval, material procurement, fabrication, quality control, and assembly preparations follow. This production and assembly phase typically takes 6-12 weeks, depending on the complexity and size of the gantry crane configuration.
Material procurement starts immediately after approval. Steel profiles, hoist systems, electrical components, and safety systems are ordered. For gantry cranes, high-quality wheels and rail systems are essential components that require careful selection.
Fabrication in the workshop includes cutting, welding, machining, and assembly of the main structure. Single-girder gantry cranes have simpler fabrication processes than double-girder systems. Semi-gantry cranes require precision machining for the asymmetric construction.
Quality control and testing are performed according to applicable standards. Weld seams are checked, moving parts tested, and safety systems verified. Mobile gantry cranes undergo additional tests for driving stability and maneuverability.
Assembly preparations include disassembly for transport, packaging, and documentation. Assembly instructions, safety procedures, and certification are prepared for on-site installation.
What are realistic expectations for total lead times?
Simple gantry cranes: 12-16 weeks, complex systems: 18-24 weeks. Single-girder gantry cranes with standard specifications have the shortest lead times. Double-girder gantry cranes and mobile variants require longer planning periods for optimal realization.
Standard single-girder gantry cranes with lifting capacities up to 15 tons can be realized within 12-14 weeks. These systems have proven designs and use standard components, enabling faster production.
Double-girder gantry cranes with lifting capacities of 20-100 tons require 16-20 weeks. The more complex construction, heavier components, and extensive engineering take more time. Special requirements may further extend the lead time.
Mobile gantry cranes and semi-gantry cranes have lead times of 18-24 weeks. These systems require specialized engineering, unique components, and extensive testing. Seasonal influences play a role, as assembly preferably takes place in favorable weather conditions.
Assembly planning can affect the total project time. Foundation work, rail installation, and electrical connections must be coordinated. Complex locations or limited accessibility may require additional time.

Frequently Asked Questions
Can the delivery time be shortened if the project is urgent?
In urgent cases, we can sometimes shorten the delivery time by giving priority to your project in our production schedules. This depends on the availability of materials and workshop capacity. Contact us immediately to discuss the possibilities.
What happens if delays occur during production?
We communicate proactively about any delays and their causes. Our project team immediately seeks solutions and alternative schedules to minimize impact. You receive timely updates on adjusted delivery times.
Are there seasons when the delivery time is longer?
Spring is traditionally our busiest period due to starting construction projects, which can lead to longer lead times. Plan your gantry crane project preferably in autumn or winter for optimal delivery speed.
What information do I need for an accurate delivery time estimate?
For accurate planning, we need your lifting capacity, span width, lifting height, type of gantry crane, and desired delivery date. Location-specific requirements such as foundations and accessibility also affect planning.
