FixonRoad.com™ truck repair blog aims to give you important information regarding trucking industry news.  As you may or may not be aware know, Big rigs and heavy haulers that transport loads over 120,000 pounds (GCW) are required to specify their trucks appropriately in respect to durability and power.

Trucks that are not accurately specified can have an adverse effect on truck fuel mileage and other operating costs including truck repair.  It is important to correctly specify the truck’s wheelbase – especially when heavy haulers are involved.

The heavy hauler industry standard for rear axles comes in at 46,000-pounds. However, in extreme cases, there are axles with capacities upwards of 150,000 pounds.

The length and weight regulations differ from state to state.  Some states follow the Federal Bridge Formula and other states have their own set of trucking requirements.

In any event, it is crucial that truck wheelbases should not be any longer than is necessary as there will be a reduction in maneuverability with respect to heavy haul tractors on congested roads.

Reinforced frame rails are sometimes needed in order to haul heavy loads.  To put it simply, the longer the wheelbase – the more axle capacity – which means that the frame will need to be more rigid.

Another factor in heavy hauler performance is the rear axle ratio.  There needs to be a balance between cruise speed and low gearing. Heavy haulers traveling over long distances at highway speeds should select ratios that are low as possible.

Rear axles need to be durable.  The heavy hauler industry standard for rear axles comes in at 46,000-pounds.  However, in extreme cases, there are axles with capacities upwards of 150,000 pounds.

Axle selection also depends on traction.  On slippery roads or muddy job sites, it may be a good idea to choose Automatic Traction Control on the antilock brake systems.

FixonRoad.com™ keeps you up to date on the latest news in the trucking industry.  Big rigs and heavy haulers that transport loads of more than 120,000 pounds gross combination weight (GCW) need to specify their trucks properly with regard to durability and power. Trucks that are not specified correctly may impact fuel mileage and increase acquisition costs.  Additionally, trucks marked incorrectly may not be powerful enough to move the load and may increase truck repair and truck maintenance costs. It is crucial to find the correct balance between the truck’s job requirement and the expected annual mileage.  This balance will help to produce the lowest operating cost per mile.

Heavy haulers can select a truck engine after-treatment approach that utilizes Selective Catalytic Reduction (SCR) technology in conjunction with Exhaust Gas Recirculation (EGR).

To complicate matters even more, this year 2010 federal truck engine emissions standards in the US and Canada may require heavy haulers to make revisions to their current trucking equipment configurations.

There are currently two choices of truck engine technologies – Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR).  The choice will impact truck performance and operating costs over the lifetime of the truck. 

Heavy haulers can select a truck engine after-treatment approach that utilizes Selective Catalytic Reduction (SCR) technology in conjunction with Exhaust Gas Recirculation (EGR).

Increased Exhaust Gas Recirculation (EGR) boosts the amount of exhaust gases in the engine cylinder.  Then it slows and cools the combustion process to burn off pollutants.  This method requires greater truck engine cooling capacity as well as an increase in the amount of fuel to be injected.

Selective Catalytic Reduction (SCR), on the other hand, does not utilize heat from the truck engine to treat emissions.  Therefore, SCR based truck engines offer the advantage of greater fuel economy.

It is a good idea for heavy haulers choosing SCR to also be sure to take into consideration Diesel Exhaust Fluid (DEF) tank capacity and placement designed for heavy haulers. This will help to ensure that heavy haul operators maintain truck wheelbase and body configurations.
