When purchasing a gantry crane, it's important to understand the different gantry crane types, specs, parts, and selection criteria so you can choose the one that will work best for your application. An affordable custom gantry crane is available from 0.25 tons to 550 tons from gantry crane engineers. In the following, the tailed information will be discussed in the buyer guide of a gantry crane.
The following factors should be taken into account when thinking about buying a gantry crane: When buying a gantry crane, the first thing to consider is the industrial gantry crane's overall use scope, working frequency, utilization, rated lifting capacity, traveling span, lifting height, and other factors.
You can choose a single girder gantry crane if the lifting capacity is less than 32 ton, the span is less than 35m, and there are no special use requirements. If you need a large width between the gantry legs, a high operating speed, or you frequently lift heavy and long objects, a double girder gantry crane is the way to go.

Why should you buy a gantry crane? What are the benefits of gantry cranes? It is possible to purchase a gantry crane at a cost-effective gantry crane cost. Consider the benefits of purchasing a gantry crane.
Companies are cautious about making large investments, particularly in the material handling industry, as the economy continues to struggle. Because large permanent overhead crane lifting solutions are expensive, businesses are looking for ways to solve their material lifting needs without making large investments. Gantry cranes are a great alternative to large, permanent crane systems because they can lift up to 10 tons and are completely mobile. As for heavy loads handling, the gantry cranes can be used to handle loads with capacity up 550 tons.
When purchasing a gantry crane, the following main parameters of gantry cranes are required:

A semi-gantry crane is a type of crane that combines an overhead crane and a motorized gantry crane design. One end of the gantry crane span is supported on the top of building structure runway , and the other end is running on the ground crane beam.
In general, the semi-gantry crane's lifting capacity determines the type of crane beam: single girder, double girder, or box girder. Single-girder semi-gantry cranes are designed to handle loads of about 20 tons, while double-girder semi-gantry cranes can handle loads of more than 20 tons.
It is critical to select the best material handling solution. But how do you choose the best semi-gantry crane for your needs? If the building is already constructed, the most appropriate overhead gantry crane should be chosen based on the specific application conditions and the size of your building. The following suggestions will help you find the best crane for your needs.
Gantry cranes are essential tools in various industries, providing the means to lift and move heavy loads with precision and efficiency. If you're in the market for a 20-ton gantry crane, you're likely working on projects that require substantial lifting capacity. Buying a piece of heavy machinery like a gantry crane is a significant investment that demands careful consideration. In this comprehensive guide, we'll explore the critical factors to contemplate when purchasing a 20-ton gantry crane to ensure it meets your operational needs and budget requirements.
The first and most crucial factor to consider is the lifting capacity. A 20-ton gantry crane can handle loads up to 20 tons, but it's essential to evaluate whether this capacity aligns with your specific lifting requirements. Consider not only your current needs but also any potential future needs. It's often wise to opt for a crane with a slightly higher capacity to accommodate unforeseen circumstances.
The span length, or the distance between the two legs of the gantry crane, is a critical factor. The span length must be sufficient to cover the working area and allow for the crane to move freely. Measure the space where the crane will be used to determine the optimal span length. If the span is too short, the crane may not have enough coverage; if it's too long, it can lead to instability and increased costs.
The height of the gantry crane is essential for ensuring that the hook path is sufficient for your specific lifting needs. Determine the height required to clear obstacles and provide adequate hook height for your lifting tasks. Additionally, consider whether you need adjustable height options for versatility in different working conditions.

Understanding the duty cycle of the gantry crane is crucial for long-term reliability and efficiency. The duty cycle refers to how frequently and for how long the crane will be in operation. Gantry cranes typically fall into one of these duty cycle categories:
Light Duty (10-20% of working time)
Moderate Duty (30-50% of working time)
Heavy Duty (60-80% of working time)
Severe Duty (90-100% of working time)
Selecting the appropriate duty cycle ensures the crane is designed to handle the demands of your operational needs. A crane designed for a higher duty cycle may cost more upfront but will provide better performance and longevity.
Another significant consideration is whether you need a fixed or mobile gantry crane. Fixed gantry cranes are anchored to the ground and offer stability but are not suitable for applications where the crane needs to be moved. Mobile gantry cranes, on the other hand, are equipped with wheels, allowing them to be relocated as needed. The choice between the two depends on the nature of your operations.
Gantry cranes are powered by electricity or diesel engines. The choice of power source can have implications for your operational costs and environmental impact. Electric 20 ton gantry cranes are more eco-friendly and typically more cost-effective in the long run. Diesel-powered cranes are suitable for remote or outdoor applications but may incur higher fuel and maintenance costs.
Gantry cranes can be operated manually or through various levels of automation. The control system you choose should align with your specific operational requirements. Options include:
Manual control with push-button pendants.
Radio remote control for remote operation and improved visibility.
Cabin or operator platform for increased safety and efficiency.
Consider the skill level of your operators and the complexity of your lifting tasks when selecting a control system.
Safety is paramount when operating a 20-ton gantry crane. Ensure that the crane comes equipped with the necessary safety features, such as overload protection, emergency stop buttons, limit switches, and collision avoidance systems. Compliance with industry safety standards and regulations is essential.
Regular maintenance is crucial to keep your gantry crane in optimal working condition. Assess the availability of local service providers and spare parts for your chosen crane model. A well-maintained crane will extend its lifespan and minimize downtime.
While the initial purchase price is a significant factor, it's essential to consider the total cost of ownership. This includes maintenance, operating costs, and potential downtime costs. While it may be tempting to opt for the least expensive option upfront, a more reliable and efficient crane may offer better long-term value.
In an increasingly eco-conscious world, consider the environmental impact of your gantry crane. Electric cranes are generally more environmentally friendly compared to diesel-powered alternatives. Green technologies, such as regenerative braking and energy-efficient components, can also reduce your crane's carbon footprint.
Choose a reputable manufacturer with a track record of producing high-quality gantry cranes. Research customer reviews and check references to ensure that the manufacturer can provide reliable and durable equipment.
Purchasing a 20-ton gantry crane is a significant decision that requires a thoughtful and well-informed approach. By carefully evaluating factors like lifting capacity, span length, duty cycle, mobility, power source, control options, safety features, maintenance, and budget, you can make a wise investment that enhances your operations and contributes to your business's success. Take the time to thoroughly research your options and consult with experts in the field to ensure that your gantry crane meets your current and future lifting needs while remaining cost-effective and reliable.
