Single Axle Vs Tandem Axle: What’s the Difference?

There are plenty of aspects to evaluate when deciding to purchase a single axle or a double axle trailer. First, you need to know is that the number of axles which will determine the number of wheels: a tandem trailer has two sets of wheels. Single axle trailers have fewer tires and brakes to maintain. So now you are questioning whether it is best to have a single or a double trailer and how those axles will impact the performances of the hauling weight.

Single Axle Trailers as the name implies, are easier to handle and makeover because they have only one axle on each end. The smaller size trailer consequently makes them more fuel economic that the tandem counterparts and often cost less to be purchased. Not only they are easier to park they are less expensive and more economical to tow. When you are purchasing a trailer you might as well think about the costs of the maintenance. In this case fewer tires result with lower replacement costs.

The biggest drawback is their smaller size, which means you can’t haul as much goods as with tandem trailers. The moving abilities are often smaller so you may be faced with certain limitations since there are only two tries to carry the weight. Although these are easier to park, you won’t feel very stable to ride on roads with bumps.

Tandem Axle Trailers is a trailer with two sets of axles, designed to handle an extra weight over any highway conditions. Tandem trailers are excellent for heavy loads as an ideal option at higher speeds. When properly loaded not only they are safer, they are also less prone to swaying. Often you have much better suspension, whatever you are hauling. By choosing a tandem model you could possibly tow more weight so the extra expense upfront is worth in the long run.

While the towing level is not so important in the first case here you need to pay more attention because if you tow unevenly only on one set of axles you are risking the life of your tires. If you carry light, your fuel economy will also suffer. If you decide to invest in a tandem trailer with more axles you should be aware that more maintenance with bearings, tyres and grease is required.

Dump Truck – Important Checks When Buying

Dump trucks are very useful at construction sites because they can be used for various tasks that vary from hauling to excavation. To get the best truck you must start by thinking about your needs and then looking at the basic parameters that matter so you are able to make a final choice that is suitable enough. When you understand important checks, you can be sure to buy a dump truck that is perfect whether you are a new shopper or you have some experience in buying the trucks.

1. Truck type – Dump trucks come in different types and each has uses and can also have some limitations. Standards trucks have a chassis with a dump bed attached as well as a vertical hydraulic lift located at the bulkhead. They have a front axle and additional ones on the rear part and they offer good maneuverability but not that good on soft soil. The other truck types are side dump trucks with limited maneuverability and transfer trucks. Know the types and relate them to your needs before you choose the most suitable one for your needs.

2. Carrying capacity – Volume and weight are what makes the carrying capacity because the final payload can also include moisture. Remember that truck that can handle heavy loads can be great, but they might face restrictions in some areas.

3. The body – Steel and aluminum are the most common materials used in making dump truck bodies. The type of job that you want to perform using the truck can help you make a good body material choice. Steel is loved for being extremely strong and it fits jobs that need heavy materials, oversized loads and rubble to be carried. Aluminum boxes on the other hand weigh less and can reduce fuel cost and it is also strong but it is expensive. Still on the body, ensure it is leveled with no sagging bends and the bed should be able to lift downwards and upwards smoothly.

4. The brake system – Dump trucks can have air brakes or hydraulic brakes. Heavier trucks are better off with air brakes because they have the robust stopping power as they work and even when they fail compared to hydraulic braking systems. For instance, a leak in air brake lines decreases air pressure and activates brakes at wheels, thus bringing the truck to a safe stop compared to leaks in a hydraulic system, brake line where fluid pressure can go down and create pressure on brake pads which eventually amounts to lost braking power and this reduces the ability of the truck to stop in the same distance.

5. Customization possibilities – Customizing a dump truck can make your tasks when using it easier. Consider how possible this is before buying your truck so you can have any additional features such as wider steps and storage boxes included to suit your job requirements. When buying from manufacturers it is very easy to have a dump truck designed to suit your needs and have all important features included for the same convenience.

Volvo Heavy-Duty Trucks: Evolution

Next year Volvo Group is going to celebrate its anniversary. Needless to say, the history of the remarkable company abounds in noteworthy events. It has been many years since Volvo produced its first heavy-duty diesel truck. So, let’s trace the evolution of long-haul offers from the world’s second largest heavy-duty truck manufacturer.

Early 1940′s – The turning point for Volvo engines

1946 was a milestone year in the history of Volvo heavy-duty trucks. Until that time, the company had been concentrating on Hesselman engines (though the diesel motor was already far superior). The reason was that one of the co-founders of Volvo, Gustaf Larson, was a fellow engineering student of Jonas Hesselman, whose creation required lower development costs. But, eventually, the call of the market and the drive for progressive change did its part and Volvo started to implement diesel engines of the pre-combustion type in the new L29 C (‘Civilian’) and the L29 V (‘Road Administration vehicle’).

Volvo Vikings’ era

One of the most remarkable triumphs for Volvo Trucks was gained by the Viking series. The company explains the success of the series by its symbolic character. Firstly, it’s about ‘V’ letter that initiates both the brand and the model name. Secondly, it reflects the genuine ‘Scandinavian’ origin that is so typical for both the ancient Vikings and Volvo vehicles.

The Viking L38 and the upgraded L48 models were significant for the 7-litre direct-injection engine and the choice between 2 or 3 axle versions (frequently featuring all-wheel-drive system).

The Titan’s fame

The Titan is another emphatic name in truck history. Its designers were among the pioneers to make a breakthrough in engine technology. Later on they presented the L39 (followed by L49) with a turbodiesel that boosted the engine output from 150 to 185 bhp. In the following decade the truck also received such outstanding features as the air-operated brake system, the power steering and the Volvo Safety Cab. Up to now, these units have been part and parcel of Volvo trucks.

The story about the Titan range would be incomplete without praising the Titan TIPTOP/F88 that became the first Volvo F-type (forward control/cab-over) truck to have unprecedented success worldwide.
