Disadvantages

• Limited Mobility: Semi-gantry cranes are designed to move along a set path, which limits their mobility within the workshop.
• Limited Capacity: The capacity of semi-gantry cranes is generally lower than that of full gantry cranes since they only have one support structure. This means that they may not be suitable for lifting extremely heavy loads or for applications that require a higher lifting height.

Specifications

Generally, semi-gantry cranes have a load capacity of up to 10t, a span length of up to 20m, and a duty group of A3-A5. If you have other needs, we can provide a custom service to produce a semi-gantry crane that meets your needs.

Single Girder Gantry Cranes Used In Workshop

Single girder gantry cranes have one girder beam that supports the trolley and hoist system. They are lightweight and easy to install, making them ideal for small workshops with limited space. Single girder gantry cranes also have a lower cost of ownership compared to double girder gantry cranes.

Avantages

Single girder gantry cranes require less material to manufacture compared to double girder gantry cranes, making them more affordable, and they have more load capacity than smaller gantry cranes. They are also easier to install, which means less downtime for your business during installation. Single girder gantry cranes can also be customized to fit specific applications and requirements. They are versatile and can be adapted to suit different lifting needs.

Disadvantages

The capacity limitations of single-girder gantry cranes are one of their main drawbacks. They are often only advised for loads up to 15 tons because they cannot handle big loads. Additionally, single girder gantry cranes may not be as stable as double girder cranes. As a result, when lifting greater items, they could be more prone to swaying or tipping.

Specifications

Generally, single girder gantry cranes have a load capacity of up to 50t, a span length of up to 50m, and a duty group of A3-A5.

Double Girder Gantry Cranes Used In Workshop

The trolley and hoist mechanism is supported by two girder beams in double girder gantry cranes. They are more stable and built to support bigger loads. Double girder gantry cranes are the best choice for large workshops that need to raise a lot of weight.

Avantages

One of the most significant advantages of double girder gantry cranes is their capacity. They can lift heavier loads compared to other gantry cranes, making them suitable for large workshops with heavy machinery. Double girder gantry cranes are also more stable, which reduces the risk of accidents and increases safety in the workplace. They can be customized to suit specific applications and requirements, ensuring optimal performance and efficiency.

Disadvantages

The greater price of double girder gantry cranes is one of their main drawbacks. They cost more to produce than other gantry cranes because they need more materials. Additionally more difficult to install, double girder gantry cranes require longer downtime. They are also less flexible compared to other gantry cranes and may not be suitable for small workshops with limited space.

Specifications

Generally, double girder gantry cranes have a load capacity of up to 800t, a span length of up to 100m, and a duty group of A3-A7.

Portable Gantry Cranes Used In Workshop

Portable gantry cranes are an ideal solution for lifting and moving heavy loads in a workshop. They are versatile, easy to move around, and can be set up quickly without the need for permanent installation.

Avantages

• Versatile: One of the biggest advantages of portable gantry cranes is their versatility. These cranes can be used to lift and move heavy loads in various locations within a workshop. They can easily be moved from one location to another, making them an ideal option for workshops with limited space.
• Cost-effective: Compared to other types of cranes, portable gantry cranes are relatively inexpensive. They are a cost-effective option for workshops that need a crane but do not have the budget for a more expensive option.
• Small Footprint: Since portable gantry cranes do not require any permanent installation, they have a small footprint. This means they take up less space in the workshop and can be easily stored when not in use.

Disadvantages

• Limited Lifting Capacity: Portable gantry cranes have a limited lifting capacity compared to other types of cranes. They are typically designed to lift loads of up to 5 tons, which may not be sufficient for some heavy-duty applications.
• Limited Height: Portable gantry cranes have a limited height range, which can be a disadvantage in some situations. They may not be able to lift objects to the required height in taller workshops.
• Stability Issues: Portable gantry cranes can be less stable than other types of cranes, especially when used on uneven or soft surfaces. This can pose a safety risk if the crane tips over while lifting heavy loads.

Specifications

Generally, portable gantry cranes have a load capacity of up to 10t, a span length of up to 10m, and a duty group of A3-A5.

Adjustable Gantry Cranes Used In Workshop

Adjustable gantry cranes are height and span adjustable gantry cranes, when used in a workshop environment, they offer more flexibility and versatility.

Avantages

• Customizable Height and Span: One of the biggest advantages of adjustable gantry cranes is their ability to be customized according to the needs of the workshop. The height and span of the crane can be adjusted to accommodate different lifting requirements. This makes them versatile and able to handle a wide range of materials.
• Easy to Move: Another advantage of adjustable gantry cranes is their portability. They are designed with wheels that make them easy to move around the workshop floor. This means that they can be positioned wherever they are needed, making material handling more efficient.
• Cost-Effective: Finally, adjustable gantry cranes are cost-effective compared to other types of cranes. They require less investment upfront and are easier to maintain over time. They are also more versatile, meaning that one crane can handle a wider range of materials, reducing the need for multiple types of cranes.

Disadvantages

• Limited Lifting Capacity: One drawback of adjustable gantry cranes is their limited lifting capacity. While they are suitable for small to medium-sized materials, they may not be capable of lifting heavier loads. This limits their usefulness in larger workshops.
