Are you aware of the carrying capacity of your truck?
Are you a tough Territorian ready to get into a new truck? But not sure if it is the right one for you? Here is what you can start with.
Strenth is often related to the size and capacity you need, and this will inevitably dictate which truck you will choose.
A truck designed for a lighter payload, when laden to excess, will simply not take the stress. Tyres will be the first component affected, since these bear all the weight on the road surface. Brakes will be the next component to suffer, since they convert the energy of a moving mass into heat during the process of bringing that mass to a halt. Clutches, transmissions, prop shafts and axles will also suffer due to the stress of carrying and accelerating a load for which they are not designed.
Overloading is dangerous.
This can affect not only the operator, but other road users as well. A truck that is kept within its rated limits is safer, not likely to be overstressed, and should enjoy a long productive working life.
Under specifying could cost you more in the long run
Simply put, saving money by purchasing a truck that doesn’t have the capacity to do the job could mean that you will be paying the price later through premature repair bills and the lost time associated with component overhauls.
To find out the minimum overall carrying capacity which meets your total load requirements, you need to have some basic knowledge about a number of elements and understand some common industry terminoloy.
GVM (Gross Vehicle Mass)
GVM is the maximum weight that the truck can carry, including its own weight, as measured where the tyres contact the road.
The kerb weight is the weight of the basic cab and chassis before any specific body has been added. It does however include an allowance for some fuel and lubricating oils, and may include the weight of a spare wheel and tyre.
Available Payload Capacity = GVM – kerb weight – tare weight
In normal life you will face more situations of towing a trailer, than when only driving a truck. The GVM is the total load the truck can carry on its own wheels, whereas GCM includes trailer weight.
GCM (Gross Combination Mass)
GCM is the total weight of the truck, trailer and their loads combined.
GCM = Weight of truck + equipment + weight of trailer + payload
The GCM on the ground should not exceed the manufacturer’s GCM rating, and trucks can not be loaded to exceed the truck’s GVM or individual axle capacities, even if the total combination weight is lower than the rated GCM.
