Semi trailer tri axle

Types of semi-trailer tri-axle

A semi-trailer tri-axle is a trailer with three axles. It spreads the weight over six wheels and is often used to carry heavy loads. The tri-axle semi-trailer has become popular in logistics because it improves road safety by reducing the risk of accidents caused by overloading. Here are the various types of semi-trailer tri-axles:

• Flatbed Truck Trailer

  A flatbed truck trailer is a semi-trailer with a tri-axle. It has a completely flat deck without railings or a roof. The semi-trailer truck can carry oversized cargo, such as construction equipment and building materials. The tri-axle distributes the weight of the load on six wheels. This weight distribution offers increased stability and reduces the risk of accidents when transporting heavy items. Flatbed trailers are vital in logistics because they allow the transportation of oversized goods that cannot fit on conventional trailers.

• Lowbed Semi-Trailer

  Lowbed semi-trailers are designed for transporting heavy equipment and machinery. They have a low deck height and a well section that accommodate large equipment. The low height and tri-axle weight distribution enhance stability. It also provides easy loading and unloading. They are commonly used for transporting construction equipment such as excavators, bulldozers, and cranes.

• Gooseneck Trailers

  Gooseneck trailers are semi-trailers that are towed by a heavy truck. They are designed for transporting livestock, cars, and other goods. The tri-axle design improves stability and maneuverability. It also offers a smoother ride, especially when transporting livestock. The gooseneck design allows for a longer neck section, improving handling and control during transport.

• Tanker Trailers

  Tanker trailers are designed for transporting liquids, such as chemicals, water, and fuel. The semi-trailer tanker tri-axle distributes the weight of the liquid cargo during loading and transportation. This weight distribution improves stability and reduces the risk of accidents. The tanker trailers have baffles and compartments. They help prevent sloshing and provide safer transport of hazardous materials.

• Reefer Semi-Trailer

  Reefer semi-trailers are designed for transporting temperature-sensitive goods. They have a tri-axle design that provides better weight distribution and stability. This feature is essential when transporting perishable goods over long distances. Reefer trailers are equipped with temperature control systems to maintain the required temperature during transport. The semi-trailer tri-axle design ensures that the cargo remains fresh and safe.

Specifications and maintenance of semi trailer tri-axle

Many manufacturers of semi-trailer trucks offer various models with different specifications to meet the needs of different buyers. Here are some general specifications of the semi-trailer tri-axle;

• Load capacity

  Generally, a semi-trailer with three axles can carry a load of up to 60,000 kg. However, this load capacity may vary depending on the model.

• Deadweight

  The deadweight of a semi-trailer tri-axle ranges from 15,000 kg to 20,000 kg. That means the trailer will weigh a maximum of 20,000 kg without any cargo.

• Overall dimensions

  The length of a semi-trailer tri-axle truck ranges from 13,600 mm to 16,500 mm. The width is about 2,500 mm, and the height is 4,000 mm. The overall dimensions may vary depending on the model.

• Tire size

  A semi-trailer tri-axle truck has 6 to 12 tires. The size of the tires ranges from 385/65R22.5 to 425/65R22.5.

• Brakes

  Usually, a semi-trailer tri-axle truck uses a disc brake. Some manufacturers may use air brakes.

Maintaining a semi-trailer tri-axle is a must for any serious truck operator. Not only will it increase the life of the truck, but it will also save the business owner a lot in the long run. Here are some of the maintenance tips for semi-trailer tri-axle:

• Regular inspections

  Inspect the truck regularly to check if there are any damages. Make sure to check the body, brakes, lights, tires, and other essential parts of the truck. This will ensure the truck is in good condition.

• Cleanliness

  Keep the semi-trailer truck clean by washing it regularly. This will prevent the truck from rusting and also keep it in good condition.

• Tire maintenance

  Tires are one of the most important parts of the truck. Therefore, it is essential to check the tires regularly to see if there are any issues. Make sure the tire pressure is at the right level and that the tread depth is even. Replace the tires immediately if they are worn out.

• Lubrication

  Make sure that all the moving parts of the semi-trailer truck are lubricated. This will reduce friction and also prevent wear and tear.

• Electrical system

  Check the electrical system of the semi-trailer truck to ensure it is working perfectly. Make sure to check the batteries, wiring, and lights.

How to Choose Semi Trailer Tri Axle

It is important to choose the right semi-trailer tri axle for specific business needs. Here are some key factors to consider;

• Load Capacity

  To choose the right semi trailer truck, first, consider the business type and average load capacity. For businesses that deal with heavy loads, like construction materials, a high-load capacity tri-axle semi-trailer is a must. On the other hand, a standard tri-axle semi-trailer is ideal for freight transport.

• Road Conditions

  Road conditions are also important when choosing a semi-trailer tri-axle. For rough roads with potholes, like the rural areas where off-road trailers are common, a rugged and stronger tri-axle semi-trailer is needed. In contrast, a standard tri-axle semi-trailer is appropriate for well-maintained highways.

• Type of Cargo

  Custom cargo types also determine the kind of semi-trailer tri-axle to be used. For example, a refrigerated tri-axle is suitable for food and perishable goods transport. In contrast, a flatbed tri-axle semi-trailer can be used for construction materials and other goods that don’t need covering.

• Loading and Unloading Mechanisms

  Businesses that require frequent loading and unloading should go for semi-trailer tri-axles with effective mechanisms. Examples are hydraulic lifts or ramps that make loading and unloading easy and fast.

• Towing Vehicle Compatibility

  Compatibility between the towing vehicle and the semi-trailer tri-axle is crucial. Ensure that the towing vehicle's hitching system is compatible with the semi-trailer tri-axle hitch. Also, confirm that the towing vehicle can handle the weight and dimensions of the semi-trailer tri-axle.

• Budget

  Budget is a key determination factor when choosing a semi-trailer tri-axle. The more advanced and customized features the semi-trailer has, the more costly it will be. Therefore, define the budget range and find a semi-trailer tri-axle that fits the budget with the required features.

How to Replace Semi-Trailer Tri-Axle

Replacing a semi-trailer tri-axle can be a complex task, typically requiring professional assistance. However, here are some general steps that can be followed:

• Identify the issue: Before any replacement can be made, it is important to know what is wrong with the current tri-axle. This can be done by visually inspecting it or performing some tests to know where the fault is.
• Prepare for replacement: Once the issue has been identified, prepare for the replacement by gathering all the necessary tools and parts that will be used for the replacement.
• Lift the trailer: Use a hydraulic jack or a trailer jack to lift the trailer off the ground. This will take the weight off the axles and make it easier to replace.
• Remove the old axles: Remove the wheels and brake components, then disconnect the semi-trailer suspension from the axles. After this, the axle can be removed by sliding it out of the suspension.
• Install the new axles: Slide the new semi-trailer tri-axle into the suspension and reconnect it. After this, the brakes and wheels should be replaced.
• Lower the trailer: Once the new axles have been installed and all components have been reconnected, lower the trailer carefully using the hydraulic jack or trailer jack.

Always consult the manufacturer's manual or a professional mechanic when replacing crucial components like axles in a semi-trailer.
