Importance of Capacity

Load Capacity Requirements

One of the primary considerations when selecting a double girder gantry crane is its load capacity. Ensure that the crane can handle the maximum weight of the materials and equipment you plan to lift. Common load capacities include:

• 10 tons
• 20 tons
• 50 tons
• 100 tons

Future-Proofing Your Decision

Consider future projects that may require a heavier load. Selecting a crane with a higher capacity than your current needs can save you the hassle of upgrading later.

Span and Height Specifications

Span Length Considerations

The span length of a double girder gantry crane is critical, particularly for railway construction. Here’s how to determine the best span:

• Operational Area: Assess the area where the crane will operate. The span should cover as much area as possible without affecting the workflow.
• Railway Specifications: Railway construction often demands longer spans to accommodate track laying and other logistics.

Height of Lifting

The lifting height should align with your operational requirements. Ensure that the double girder gantry crane can easily handle the heights necessary for your project.

Mobility and Flexibility

Fixed or Mobile?

Double girder gantry cranes can be fixed or mobile. Depending on your project requirements:

• Fixed Gantry Cranes: Ideal for stationary applications where maximum stability is a priority.
• Mobile Gantry Cranes: Provide flexibility, allowing movement across different sites, which can be advantageous during extensive railway projects.

Safety Features

Essential Safety Functions

Safety is paramount in any construction setting. Ensure that your double girder gantry crane includes essential safety features such as:

Control Systems

Manual vs. Automatic Controls

Modern cranes come with various control systems. Evaluate the control options:

• Manual Controls: May be more straightforward to operate but require skilled personnel.
• Automatic Controls: Enhance precision and can reduce labor costs.

Remote Control Options

Consider cranes that offer remote control capabilities, which can improve safety and efficiency during operations—especially useful in complex railway project environments.

Common Concerns and Solutions

Confusion Over Specifications

If you're unsure about what specifications to choose, consult with specialists who can provide tailored advice based on project requirements.

Budget Constraints

If budget is a concern, look for second-hand or refurbished double girder gantry cranes. Ensure that they meet quality standards and have valid inspection certificates.
