When we talk of a tandem axle truck, we usually refer to a truck that is fitted with two drive axles which is similar to the rear of an eighteen wheeled tractor. This kind of truck is usually fitted with eight wheels and tires on the drive axles. Hence, a lot of weight can be supported by this kind of a truck even if the road conditions are poor as the traction is improved to a great extent.
The axle positioning
The lead axle gets the power from the engine and the axle that trails behind is providing power by a drive shaft that extends from the rear end of the lead axle. The drivers are able to distribute power between the two axles. They can choose to obtain power through the front axle or divide the power between the two. The trailer company might also provide van trailers for sale.
Ideal for certain businesses
For businesses that need vehicles to act as dump truck, tanker or cement mixing truck can opt for this truck model. The trailer companies that provide these trucks for hire will also provide vms board hire. The trucks are equipped with spring packs that are designed in order to withstand heavy load during transportation. Torque is applied on both the drive axles so that the truck can make a smooth start when it is starting to move. The weight as well as the torque gets distributed evenly over a board and large area.
When used as dump trucks
When this kind of a truck is used as a dump truck, the axle springs on the rear is heavy duty and can support the heavy weight when the truck is loaded. When the dump box is raised, the axle springs on the rear help to stabilize the truck. When liquid is carried in the back of a truck, tires could get destabilized and if the suspension is weak, it could fail when this kind of load is carried. This could happen more when the road conditions are unstable.
Extra fittings for rough road conditions
Those business owners who are looking at these truck models for carrying loads across secondary roads or dirt tracks, the models need to be fitted with an airlift. It is the third axle that will try and displace the weight over a wider area. With this mechanism the truck will not get stuck when traveling on soft ground or when there are weight restrictions on certain roads or during different seasons. Many bridges have weight limits and that can be arrived at by dividing the total weight, carried upon each axle to stay within allowed limits.
