Cantilever portalkran: Tillämpningar och fördelar

If you’re in the market for a reliable and efficient lifting solution, a cantilever gantry crane could be just what you need. These cranes are versatile and come in various types and configurations, making them suitable for various industries. In this article, you can see the different types of cantilever gantry cranes and have a more detailed understanding of their benefits, applications, and factors to consider when purchasing.

Various Types Of Cantilever Gantry Crane

Single Girder Cantilever Gantry Cranes

Single-girder cantilever gantry cranes have a single girder that supports the load. The girder is attached to a vertical column on one end and extends horizontally beyond the supporting column. This type of crane is ideal for lifting and transporting loads up to 20 tons. Single girder cantilever gantry cranes are easy to install and operate, making them a cost-effective solution for various businesses.

• Referensprisintervall: $2000/set-$50000/set

Double Girder Cantilever Gantry Cranes

Double girder cantilever gantry cranes are similar to single girder gantry cranes, but they have two girders instead of one. The two girders are attached to a vertical column on either end and extend horizontally beyond the supporting columns. Double girder cantilever gantry cranes are more robust than single girder gantry cranes and can lift heavier loads, typically up to 100 tons. These cranes are commonly used in shipyards, steel mills, and other heavy industries.

• Kapacitet: upp till 800t
• Spännlängd: upp till 100m
• Cantilever length: 5m-15m

• Reference Price Range: $5000/set-$100000/set

Truss Cantilever Gantry Cranes

Truss cantilever gantry cranes are designed to support very heavy loads, usually ranging from 10 to 200 tons. These cranes have a truss structure that can bear large wind pressure and provide additional strength and stability, making them ideal for lifting and transporting large objects. Truss cantilever gantry cranes are commonly used in the construction of bridges, ships, and other large structures.

• Kapacitet: upp till 200t
• Spännlängd: upp till 100m
• Cantilever length: 5m-15m
• Servicegrupp: A3-A5
• Arbetsmiljötemperatur: -25°C〜+50°C, relativ luftfuktighet ≤95%
• Reference Price Range: $5000/set-$100000/set

Benefits Of Cantilever Gantry Cranes

Increase Span

One of the main advantages of cantilever gantry cranes is their span. Because of their design, these cranes can reach further and cover a larger area than traditional cranes. This makes them ideal for use in large warehouses or outdoor storage areas where space is at a premium. The cantilever arm allows the crane to extend beyond the support structure, giving it greater range and accessibility. With a cantilever gantry crane, you can easily move heavy loads across a wide area without having to reposition the crane multiple times.

Förbättrad effektivitet

Cantilever gantry cranes can increase effectiveness. They can quickly travel throughout a facility thanks to their mobility, which cuts down on the time needed to complete duties. They are vital equipment for companies that frequently handle materials since they can easily lift and move huge loads. Businesses can enhance productivity while lowering the danger of worker injuries by utilizing a cantilever gantry crane.

Förbättrad säkerhet

Safety is always a top concern when it comes to heavy machinery. Fortunately, cantilever gantry cranes exceed expectations in terms of safety. They come equipped with several safety features, such as overload protection, anti-collision sensors, and emergency stop buttons. Additionally, operators can control the crane’s movements from a safe distance using a remote control, minimizing the risk of accidents. The enhanced safety features of cantilever gantry cranes make them an excellent choice for businesses that prioritize worker safety.

Various Specifications

Cantilever gantry cranes come in various sizes and configurations, offering users a wide range of options to choose from depending on their specific needs. Some models are designed to handle smaller loads, while others can lift several tons of weight. Additionally, cantilever gantry cranes can be customized to fit different work environments.

Applications Of Cantilever Gantry Cranes

Prefabrication Yard

In prefabrication yards, cantilever gantry cranes play an important role in the construction of large structures such as bridges and buildings. These cranes are used to lift heavy prefabricated components and move them into place for assembly. Cantilever gantry cranes are ideal for this application because they can provide a high lifting capacity while maintaining a small footprint.

Stone Yard

In stone yards, cantilever gantry cranes are commonly used for the handling of large blocks of stone. They can be fitted with specialized attachments such as clamps or magnets, which allows for precise lifting and positioning of stone blocks. With the help of cantilever gantry cranes, stone yards can increase their productivity while reducing the risk of accidents and injuries.

Hamnar

Cantilever gantry cranes are used at port to load and unload cargo from ships. These cranes are mounted on rails and can move along the length of the dock. The crane can lift cargo from a ship’s hold and deliver it to the dock thanks to its extended arm that is over the sea. Container ships can also be loaded and unloaded using cantilever gantry cranes.

Choose The right Cantilever Gantry Crane

1. Type of load: Different types of materials have different handling requirements, and need to be equipped with different spreaders and different types of cranes. Therefore, when selecting a cantilever gantry crane, you need to consider the type of material you plan to lift. Materials such as concrete require a crane with a higher weight capacity than lighter materials such as wood.
2. Capacity: You should always select a crane with a weight capacity that exceeds the maximum weight of the heaviest object you plan to lift.
3. Height: The height of the crane will depend on the height of the objects you plan to lift. You should ensure that the crane’s height surpasses the objects’ height to avoid accidents and enable smooth operation.
4. Span: You should take into account the width of the area where you plan to use the crane when determining the span. Ensure that you choose a crane with a span wide enough to allow free movement of the crane while lifting objects.
5. Construction and design: The material used for the construction must be durable enough to withstand heavy loads and harsh weather conditions. Additionally, the design should be efficient and practical, allowing for optimal use of space and ease of operation.
6. Safety: Ensure that the crane has all the necessary safety mechanisms, including overload protection, emergency stop buttons, and limit switches to prevent accidents and injuries.
7. Size and mobility: If you have limited space in your workspace, a compact crane with a small footprint may be the best option. Alternatively, if you need to move the crane around frequently, a mobile gantry crane may be more suitable.

A cantilever gantry crane is a versatile and efficient lifting solution for various industries. Its unique cantilever design allows it to reach over obstacles, making it ideal for loading and unloading cargo from ships or transporting materials across buildings. Investing in a cantilever gantry crane can increase efficiency, improve safety, and offer cost savings. Before purchasing a cantilever gantry crane, it is essential to consider load capacity, height requirements, site conditions, and safety.
