Choosing the best type of axle for a trailer is not always an easy choice and issues such as safety, maneuverability and comfort are all points you should take into account when making your decision.

For this reason, we have prepared an article that presents the most important characteristics of the four main types of axle: fixed, self-steering, hydraulic forced steering and electronic forced steering.

FIXED AXLE This is the simplest type of axle and, naturally, the most economical of the four. However, since the trailer is dragged in the direction imposed by the tractor, it is subject to greater tire wear.

SELF-STEERING AXLE It is an axle that makes the wheels follow the direction taken by the tractor and can swing freely. It improves the maneuverability of the trailer compared to the fixed axle, reducing tire drag and consequently wear. It allows the axle to be locked in both directions, guaranteeing wheel alignment. The self-steering axle can be used unlocked in traffic up to a maximum speed of 15 km/h, after which it must be locked by the tractor driver.

HYDRAULIC FORCED DIRECTIONAL  Axles that, when connected to the tractor, accompany and facilitate the tractor's bending to the right or left, reducing tire wear due to drag. In other words, when the tractor curves, the cylinder installed under the coupling device parallel to the boom is activated, following the radius of curvature and facilitating the maneuver.

Economic and population growth are determining factors in our growing production needs. This is why we have seen a new way of working in agriculture, focusing on innovation and technology.

It is in this context that we find agricultural robots, which are expected to play an even greater role in the agriculture of the future, driving innovation and promoting sustainability throughout the food chain.

Aware of this global trend, Herculano teamed up with INESC-TEC to develop Modular-E, a robot presented at World FIRA 2024, a promising trade fair for agricultural robotics, with several companies presenting innovative solutions aimed at improving the efficiency and sustainability of food production.

This fair featured discussions and workshops dedicated to the challenges and opportunities of robotics in agriculture. Various experts in the field shared their vision of how automation and robotics can help farmers increase productivity, reduce costs and minimize the environmental impact of their operations.

There were also several demonstrations that gave FIRA participants a practical view of how these technologies are being implemented in the field. This equipment showed its ability to work together with farmers, responding to the challenges faced by modern agriculture.

The Modular-E Concept

It is an autonomous modular robot for woody crops with advanced navigation capabilities. Monitoring allows the collection of visual and 3D point cloud data to feed decision support systems.

Equipped with advanced movement systems, Modular-E can move efficiently over a variety of terrains and obstacles. The robot has a variety of sensors, including cameras, a LIDAR sensor and GPS antennas, which provide a detailed perception of its surroundings.

It also works as a fertilizer applicator using variable rate technology and NPK sensors, for soil and leaves. It also has an ultra-efficient electric tool for controlling vegetation growth in row and inter-row crops. Automatic harvesting in terraced vineyards will be available in 2025. And in the future, in addition to harvesting, pruning will also be possible.

Announcement Herculano

In solidarity with farmers across the country, Herculano wants to express its unconditional support for the demonstrations that began this Thursday.

We recognize and value the vital role played by farmers in feeding the country and its economic sustainability. We believe that the delay in the payment of production support and the cutting of subsidies show a profound disrespect for the hard work, tireless dedication and resilience shown by farmers. We therefore believe that protests are a legitimate means of demonstrating their discontent and calling for their urgent needs to be heard.

Herculano believes that it is essential to chart a course that promotes open and constructive dialog between the parties involved. An example of this was the meeting between agricultural representatives and the Ministry of Agriculture.

Nevertheless, we call on the government to proactively continue to support agricultural production and mobilize the necessary EU support for national farmers. It is crucial to consider policies that encourage innovation, offer financial and technical support and promote environmentally conscious farming practices.

We extend our support and solidarity to the farmers across Europe who are currently expressing their concerns and demands through protests.

We are committed to working together with the farming community, the government and stakeholders to ensure a brighter future for agriculture in our country.

With you on the ground.

The year began with the launch of a new product Herculano: the H-BOX.

Knowing the difficulties of manpower in agriculture, the use of these containers in harvesting is becoming increasingly popular, as it reduces the number of tractors and drivers needed for each operation. In this case, the work can be managed by two people: one at the combine harvester; and a second who drives the tractor with the box carrier and manages a number of boxes distributed over the cultivated area.

The versatility of this product means that it can be used not only in agriculture, namely in arable crops, cereals, oilseeds and protein crops, but also in construction or municipal services. It all depends on the owner's needs and the use to which they want to put their equipment. In this case, purchasing a product of this type is more economical due to the profitability of its use.

Like the monocoques Herculano, these containers are also designed with a conical box to make unloading easier, and are also prepared to integrate additional rails to increase their capacity. These containers are also prepared for use on tractors or container trucks.

Agricultural trailers are essential equipment in modern agriculture, providing efficient transportation of all kinds of agricultural products and their derivatives, and they can also be used in industry and public works.
One of the key elements that has a significant impact on their performance and stability is the suspension system. In agriculture, four types of suspension are often used: mechanical bogie suspension, mechanical tandem suspension, mechanical tridem suspension and hydraulic suspension (axle or semi-axle).

1. Mechanical bogie suspension

This is the best-known type of suspension and is most commonly used on agricultural trailers, with two axles connected to each other by a suspension (sets of springs). They are mostly used because of their adaptability to various types of terrain. It is the ideal and most economical type of suspension for use on agricultural land and uneven surfaces.

Advantages:

• Cost: It's the most economical suspension and the easiest to maintain.
• Handling: Efficient handling on uneven terrain.

Disadvantage:

• Amplitude: The height of the equipment in relation to the ground cannot be adjusted.

2. Tandem and tridem mechanical suspensions

Tandem suspension involves the use of two axles, while tridem suspension uses three. In both cases, the axles are supported by spring beams. It is a common choice for many agricultural trailers, which travel over flatter, longer terrain and roads.

Advantages:

• Driving: Suitable for long journeys.

Disadvantages:

• Stability: Although more stable on the road, they are not as efficient in the field.
• Amplitude: The height of the equipment in relation to the ground cannot be adjusted.

3. Hydraulic suspension (axle or semi-axle)

In the world of modern agriculture, efficiency and safety are paramount considerations. Hydraulic suspension systems offer several advantages over traditional mechanical suspension configurations.

Advantages:

• Stability: One of the main advantages of hydraulic suspension on agricultural semi-trailers is greater stability and controllability, which means that the equipment is always level.
  It also allows the height and rigidity of the suspension to be adjusted.
• Vibration and impact reduction: Reducing vibr ations and impacts guarantees the integrity of the load and extends the life of the semi-trailer, reducing maintenance costs.

Disadvantage:

• Cost: This is the type of suspension with the highest cost.

Conclusion

The choice of suspension system depends on the specific needs and considerations of the user. Although mechanical suspensions are the most requested, for more intensive and professional use, hydraulic suspension is recommended.

A careful assessment of factors such as load requirements, terrain and budget will help farmers and professionals choose the best solution.

With the main objective of complying with European homologation requirements, Herculano has launched a new product line, air, with pneumatic brakes. This commitment represents the company's alignment with European markets, focusing on standardizing the product according to quality and safety standards.

Knowing that stability and safety are two very important aspects for users, Herculano has been committed to offering reliable and safe equipment from an early stage, namely through the air braking system.
The air braking system uses the compressed air generated by the tractor to activate the brake chambers, in which the air is directed into the chambers, which apply pressure to the brake jaws, resulting in the trailer being braked. The braking force is controlled by the ALB system, which automatically adjusts the braking force according to the load on the trailer.

Several advantages over hydraulic braking include:

• Effective braking performance: air braking makes it technically easier to meet the technical criteria required by European regulations
• Increased reliability and safety: highly tested components, as they have been used for many years in industrial vehicles/motorcycles
• Guaranteed environmental performance: system that does not use potentially polluting liquids, as is the case with hydraulic systems.

The products we currently have with the air version are Monocoques (HMB 2 and 3 axles, HMB RG, HTP, HDPA), Multifunction Trailers (Europa and Platform), Tanks (2 and 3 axles and RG) and Spreaders (H2RS 2 axles) - with European Approval we also have the iS1ET 1-axle multifunction trailer models, but with inertia brakes.

This simple and intelligent product is considered the best wheel-tightening indicator available on the market. It is designed to indicate their possible loosening on commercial vehicles.

This intelligent solution helps ensure that every driver or user of your trailer can carry out quick and easy visual checks and audits on the wheels of their vehicles.

FUNCTION

Its working principle is to visually indicate the position of the clamping element. By placing the checkpoints in a recognizable pattern, such as tip to tip, any movement is clearly visible at a glance. As well as helping to quickly identify loosening, it is also easy to see whether or not this element has been lost. In addition, it melts at a specific temperature (125ºC) to highlight any wheel or hub overheating problems.

This product is available as standard on Monocoque, Europa, Campanha, Cisterns >= 8000, H2RS spreaders and Platforms.
