Price Differences Between Single and Double Girder Gantry Cranes

Gantry cranes are essential lifting equipment in a wide range of industries, from construction and manufacturing to logistics and shipbuilding. Among the many types of gantry cranes available in the market, single girder and double girder gantry cranes are two of the most commonly used. While both types serve similar functions—lifting and transporting heavy materials—their design, capabilities, and price points can differ significantly. Understanding these differences is critical for businesses looking to invest in the right crane solution for their operations.

In this article, we’ll explore the price differences between single and double girder gantry cranes, including the factors that contribute to cost variation and guidance on how to choose the right type based on specific application needs.

What Are Single and Double Girder Gantry Cranes?

Single Girder Gantry Cranes

A single girder gantry crane for sale consists of one horizontal beam (girder) supported by legs that move along rails or wheels. The hoist typically runs on the bottom flange of the girder. These cranes are commonly used for light to medium-duty lifting, with lifting capacities usually ranging from 1 ton to 20 tons. They are economical, easier to install, and require less structural support compared to their double girder counterparts.

Double Girder Gantry Cranes

Double girder gantry cranes have two horizontal beams, which provide greater structural integrity and lifting power. The hoist typically travels on top of the girders, allowing for increased lifting height. These cranes are ideal for heavy-duty applications, with capacities commonly ranging from 10 tons to over 500 tons. Double girder designs are preferred in demanding industrial environments where high lifting capacity and precision are required.

Core Differences Impacting Price

There are several factors that explain the price differences between single and double girder gantry cranes:

1. Structural Complexity and Material Usage

Double girder cranes require more steel and additional structural components to support the second girder. This results in a heavier, more robust crane design that naturally increases material and manufacturing costs.

• Single girder cranes use less material, making them more cost-effective.

• Double girder cranes are heavier and more complex, which contributes to a higher base price.

2. Lifting Capacity and Span

Double girder gantry cranes generally offer higher lifting capacities and longer spans, which necessitate a stronger structure, more powerful hoisting mechanisms, and enhanced stability.

• For example, a single girder crane with a 10-ton capacity and 20-meter span may cost significantly less than a double girder crane with a 50-ton capacity and 35-meter span.

• Higher capacity often means more advanced engineering, which drives up the price.

3. Hoist Placement and Lifting Height

In single girder cranes, the hoist is mounted below the girder, which can limit the lifting height. In double girder cranes, the hoist runs on top of the girders, allowing for maximum lifting height—especially important in large factories or construction environments.

• Achieving greater lifting height adds to the complexity and price of a double girder system.

• Projects requiring more vertical space are more likely to benefit from (and pay more for) double girder models.

4. Installation and Transportation Costs

Due to their size and weight, double girder gantry cranes usually require more involved installation processes, including specialized equipment for assembly and alignment.

• Single girder cranes are lighter and easier to install, often with reduced labor and logistics costs.

• Double girder cranes may require professional installation teams and cranes for setup, which adds to the overall expenditure.

5. Control Systems and Optional Features

Double girder gantry cranes are often paired with advanced control systems, such as PLCs, automation features, anti-sway mechanisms, and cabin control. These add functionality and safety but increase the total cost.

• Many single girder models are operated via pendant or remote control, with fewer optional features.

• High-end double girder cranes may include intelligent diagnostics, position tracking, and integration with plant systems.

General Price Comparison

Although prices vary based on manufacturer, specifications, country of origin, and project requirements, here is a general comparison of price ranges (as of 2025):

Crane Type	Capacity	Span	Price Range (USD)
Single Girder Gantry Crane	5 tons	10–20 m	$15,000 – $35,000
Single Girder Gantry Crane	10 tons	15–25 m	$25,000 – $50,000
Double Girder Gantry Crane	20 tons	20–30 m	$50,000 – $90,000
Double Girder Gantry Crane	50 tons	30–40 m	$90,000 – $150,000
Double Girder Gantry Crane	100+ tons	30–50 m	$150,000 – $300,000+

Note: These are approximate estimates. Gantry crane prices can vary due to customization, supplier pricing strategies, shipping costs, and local taxes or tariffs.

When Is the Higher Price of Double Girder Cranes Justified?

Although double girder gantry cranes are more expensive, they deliver better performance for heavy-duty tasks. Their advantages include:

• Higher lifting capacity

• Longer spans and better stability

• Increased lifting height

• Longer service life under heavy use

• More flexible customization options

If your business involves frequent lifting of loads above 20 tons, double girder cranes may be a more economical solution in the long run due to reduced downtime and better load handling.

When Is a Single Girder Gantry Crane the Better Investment?

For operations that involve lighter lifting tasks (such as under 10 tons), limited space, or budget constraints, single girder gantry cranes are a smart choice. They are easier to install and maintain, and their lower upfront cost makes them attractive to small to mid-sized businesses or short-term projects.

Applications include:

• Workshops and small factories

• Outdoor material handling with light loads

• Maintenance yards and warehouses

• Short-span construction sites

How to Choose the Right Crane for Your Budget

When evaluating gantry cranes, don't just look at the upfront price—consider total cost of ownership, which includes:

• Energy consumption

• Maintenance and repair costs

• Downtime losses

• Operator efficiency

• Long-term scalability

It's also critical to choose a reputable crane supplier who offers:

• Engineering consultation

• Custom design services

• Installation and commissioning

• After-sales support

Investing in the right crane can significantly enhance productivity, safety, and profitability over time.

Final Thoughts

The price difference between single and double girder gantry cranes reflects differences in design, capability, and application suitability. While single girder gantry cranes are cost-effective for lighter-duty lifting needs, double girder gantry cranes provide superior strength, durability, and functionality for more demanding operations.

Ultimately, the best crane for your needs depends on your load requirements, site conditions, and long-term operational goals. Carefully evaluating these factors will help ensure you make an investment that delivers both performance and value.
