If you have enough people, you could lift it manually. For lifting wheels, though, a jack is more common.
A wheel and axle....
a pulley and wheel and axle
A Class 8 truck is a vehicle with a Gross Vehicle Weight Rating of over 33,000 lbs. Single axle trucks with an additional lift axle, tandem axle trucks, tandem axle trucks with additional lift axles, and tractor-trailer dumps are all Class 8 trucks.
You need to be more specific about the configuration. Is a single axle straight truck, a tandem axle straight truck, a tandem axle straight truck with additional lift axles, a tractor trailer...?
No. A tri-axle has one additional lift axle; a quad axle has two lift axles.
It's pretty cut-and-dry.. it's an axle which can be raised and lowered. Normal five axle units don't have them - they tend to be exclusive to heavy haulers. You see them on a lot of straight trucks, as well, such as dump trucks.
That's talking about a vehicle, not an axle. A 6x2 vehicle has six wheel assemblies, and two are driven. So you'd be looking at three axles total (two wheel assemblies per axle), one of which would be a live axle with a differential, and the other two would be dead axles which are not driven... there'd be a steer axle, and the other dead axle could be a stationary axle, or it could be a lift axle. The powered axle could be either the forward or rear drive axle - it doesn't have to be one or the other.
NO. Even without the lift, I think the trailer would be driving you at 50mph. Also, depending on which 4 speed you have, the transmission might not last.
If the lorry contains the birds in a sealed container then the weight is unchanged. As they lift from their perches they must accelerate and the resultant downward force on the lorry will make it appear to weigh more for a very short time.
The pink horse is the symbol for Elite Bedding a company that supplies horse bedding. Stobart deliver for them and they asked Stobarts if they could have a truck in that livery and it was agreed. The lorry also has its own folk lift known as a 'pig' because its having a piggy back on the back of the trailer to make loading and unloading easier.
It allows the vehicle to carry more weight.
