• What is a mobile portal crane used for?

A mobile gantry crane is used for lifting and moving heavy loads at locations where flexibility and mobility are essential. These crane systems provide a practical solution for temporary lifting operations, construction projects, and industrial applications where fixed installations are not suitable. Mobile gantry cranes combine the power of traditional gantry cranes with the advantages of portability and rapid deployment.

What is a mobile gantry crane and how does it work?

A mobile gantry crane is a portable lifting installation consisting of two vertical support legs connected by a horizontal beam to which the hoisting system is attached. This construction forms a gantry shape that can be positioned over objects to lift and move them.

The operating principle is based on a stable A-frame or rectangular frame construction that rests on wheels or tracks. The horizontal girder contains rails along which a hoist trolley can move, allowing loads to be moved both vertically and horizontally. This distinguishes mobile gantry cranes from other lifting solutions through their ability to maneuver completely around objects.

Technical characteristics that make this crane type unique include the possibility for quick disassembly and transport, adjustable spans, and the capacity to work without permanent foundation. Various configurations are available, from single girder gantry cranes for lighter loads to double girder gantry cranes for heavier applications.

In which industries are mobile gantry cranes most commonly used?

Mobile gantry cranes find their application primarily in shipping, ports, construction sector, manufacturing industry, and logistics centers. These sectors value the flexibility and cost-effectiveness of these lifting solutions for various operations.

In shipping and ports they are deployed for loading and unloading containers, moving ship components, and maintenance work on vessels. The mobility makes it possible to quickly switch between different quays and work locations.

The construction sector uses mobile gantry cranes for placing prefabricated elements, lifting building materials, and assembling large structures. Manufacturing facilities use them for moving machinery, handling large workpieces, and maintenance work on production lines.

In logistics centers and storage facilities, these cranes are used for loading trucks, stacking containers, and reorganizing storage spaces. Semi-gantry cranes are popular in these environments due to their efficient space utilization.

What are the main advantages of a mobile gantry crane?

The main advantages of mobile gantry cranes are their mobility, flexibility, and cost-effectiveness compared to fixed crane systems. They can be quickly deployed at different locations without permanent installation or foundation.

Mobility means that one crane can be used for multiple projects, spreading the investment across more applications. Flexibility manifests in adjustable configurations for different lifting capacities and spans, depending on specific requirements.

Cost advantages arise because no permanent foundation is needed and the crane can be rented or leased for temporary projects. This makes them ideal for construction projects, maintenance work, and seasonal activities.

Versatility shows in the ability to work both indoors and outdoors, handle different load types, and combine with other lifting aids. The quick setup and breakdown time significantly increases operational efficiency.

What lifting capacity and dimensions are possible with mobile gantry cranes?

Mobile gantry cranes are available with lifting capacities from 500 kg to 250 tons, spans from 3 to 40 meters, and lifting heights up to 12 meters. The choice for specific dimensions depends on the loads to be handled, available space, and transport requirements.

Single girder gantry cranes are suitable for capacities up to approximately 20 tons with spans up to 25 meters. They offer a cost-effective solution for lighter applications and have a lower construction height.

Double girder gantry cranes can handle heavier loads up to 250 tons with larger spans. This construction offers more stability and precision for critical lifting operations in heavy industrial applications.

Factors influencing the choice include maximum load weights, required lifting height, available workspace, transport possibilities, and budget considerations. The frequency of use and the need for precision in positioning also play an important role in the selection.

Frequently Asked Questions

How long does it take to set up and make a mobile gantry crane operational?

Setup time varies from 2-4 hours for smaller cranes to a full working day for large double girder systems. This depends on crane size, complexity, and the experience of the assembly team. BKRS ensures quick and professional installation by certified technicians.

What ground conditions are needed for safely setting up a mobile gantry crane?

A flat, solid surface that can bear the weight of the crane plus maximum load is essential. For heavy cranes, temporary foundation or load distribution plates may be necessary. Our specialists advise on the proper ground requirements for your specific situation.

Can a mobile gantry crane be used in bad weather or outdoors?

Yes, mobile gantry cranes are designed for outdoor use, but wind speed and weather conditions determine operational limits. At wind speeds above 10-15 m/s, use is not recommended. BKRS supplies cranes with wind measurement equipment for safe working conditions.

What are the maintenance costs and frequency for a mobile gantry crane?

Periodic inspection is legally required (annually), plus daily visual checks by operators. Maintenance costs average 3-5% of purchase value per year. BKRS offers maintenance contracts for preventive maintenance and 24/7 service support.
