Come scegliere una gru a cavalletto da esterno per il sollevamento di carichi pesanti

If you have heavy equipment or materials that need to be moved outdoors, then an outdoor gantry crane could be the perfect solution. However, with so many different options available, it can be difficult to know where to start when selecting the right one for your specific needs. In this article, we will provide a comprehensive guide on how to choose an outdoor gantry crane for your heavy lifting.

Available Outdoor Gantry Cranes

Before choosing an outdoor gantry crane, it is important to understand the different types available. Here are some of the most common:

Gru a cavalletto monotrave

Single girder gantry cranes are designed with one bridge beam supported by two legs. They are perfect for light-duty jobs like loading and unloading supplies in a little workshop or yard. Because of their straightforward construction, single girder gantry cranes are simple to install and maintain. They are also more affordable and take up less room than other gantry crane kinds.

Gru a cavalletto a doppia trave

Gru a cavalletto bitrave have two bridge beams that are supported by four legs. They are designed for heavy-duty applications, such as lifting containers in shipping ports or moving large machinery in factories. Double girder gantry cranes have a higher lifting capacity than single girder gantry cranes, making them suitable for handling heavier loads. They can also span longer distances than single-girder gantry cranes.

Gru a cavalletto a traliccio

IL gru a cavalletto a traliccio is another kind of outdoor gantry crane. This crane has a triangular truss structure, which adds strength and stability and allows for the lifting and long-distance transportation of big cargo. Truss gantry cranes are frequently used to lift and move steel beams, precast concrete components, and other building materials on open-air construction projects.

Truss gantry cranes are renowned for their versatility and can be adapted to various applications by adding different types of hoists and trolleys. They are ideal for projects that require lifting and transporting heavy materials over uneven terrain or difficult working conditions.

Gru a cavalletto per container

As the name suggests, container gantry cranes are specially designed for lifting and moving shipping containers. These cranes have a spreader beam that can be adjusted to fit different sizes of containers and allows for quick and efficient loading and unloading of cargo from ships.

Container gantry cranes are commonly used in shipping ports, where they handle the majority of cargo operations. They are capable of lifting and transporting containers weighing up to 60 tons, making them an essential tool for international trade and logistics.

Precast concrete gantry cranes are designed specifically for lifting and moving precast concrete components including walls, beams, and columns. These cranes typically have double girder construction and can lift loads weighing up to 100 tons.

Precast concrete gantry cranes are a common sight on outdoor building sites and are essential for putting precast concrete structures together. They are renowned for their accuracy and effectiveness, which enables workers to finish projects on schedule and within budget.

Choose The Best Outdoor Gantry Crane For Your Heavy Lifting

If you have a small to medium-sized operation with loads up to 50 tons, then a single girder gantry crane would be more appropriate. For heavier loads or larger operations, a double girder gantry crane may be necessary. Truss gantry cranes are ideal for outdoor applications that require additional stability in high wind areas. Container gantry cranes are designed specifically for container handling at ports and terminals. If you’re working in the construction industry and need to move precast concrete elements, then a precast concrete gantry crane is your best option.

After choosing the type of outdoor gantry crane, there are also several important factors to consider. The first is the crane’s load capability; you must ensure that it can hoist the heaviest weights you intend to lift. You should also consider the maximum lifting height necessary, as well as the height and width of the region where the crane will be deployed. In addition, ensure sure the crane has sufficient safety features like emergency stop switches, overload protection, and limit switches. Finally, search for a reliable manufacturer or supplier with experience in producing outdoor gantry cranes.

Safety Devices For Outdoor Gantry Crane

Safety should always be a top priority when using any type of gantry crane. Here are some safety devices to look out for:

• Overload Protection: An overload protection device will prevent the crane from lifting loads that exceed its weight capacity.
• Emergency Stop Button: In case of an emergency, an emergency stop button can quickly shut down the crane and prevent damage or injury.
• Limit Switches: Limit switches will automatically stop the crane when it reaches its maximum height or travel distance.
• Wind Sensors: If you live in an area with high winds, wind sensors can detect strong gusts and automatically shut down the crane to prevent it from tipping over.

How To Maintain The Outdoor Gantry Crane?

Outdoor gantry cranes are crucial for lifting and transporting heavy loads in various industries. However, they are also damaged due to their exposure to harsh weather conditions. Therefore, it is essential to prevent crane damage by following some simple maintenance tips.

Clean Regularly

The first step to maintaining an outdoor gantry crane is to clean it regularly. Dirt, grime, and other debris accumulate on the crane’s surface and may damage the gantry crane. Therefore, it is necessary to remove any dirt or debris from the crane’s surface using a high-pressure washer or a stiff-bristled brush. Additionally, make sure to clean the crane after each use to remove any residue that might have accumulated during the operation.

Apply Anti-Rust Coating

Applying the anti-rust coating is an efficient method of preventing rust formation on an outdoor gantry crane. By forming a barrier between the metal surface and the environment, an anti-rust coating stops moisture and oxygen from corroding the metal. Depending on the material and location of the crane, several anti-rust coatings, such as paint, oil, or wax, are available. It’s crucial to pick the proper coating and to coat the crane’s surface equally.

Lubrificare le parti mobili

Lubricating the moving parts of an outdoor gantry crane is crucial to prevent rust buildup. The crane’s moving parts, such as gears, pulleys, and bearings, need to move smoothly to avoid friction and wear, which can lead to rust. Therefore, it is essential to lubricate these parts with a high-quality lubricant, such as oil or grease, to keep them functioning correctly. Additionally, lubrication can help remove any rust buildup on the moving parts, extending the crane’s lifespan.
