If I remember correctly, each hole on trailer tandems is approximately 500 lbs., and each hole on a sliding fifth wheel is supposed 250 - 300 lbs. Bear in mind that these are just averages, and can vary by manufacturer.
Tandem by definition is two. So tandem axle is two axles. Example would be a tractor trailer having two axles next to each other is a tandem axle.
If you have a sliding fifth wheel, you can transfer weight from the drive axles to the steer axle by sliding it forward, or you can transfer weight from the steer axle to the drive axles by sliding it back. If you have sliding tandems on your trailer, you can transfer weight from the drive axles to the trailer axles by sliding the trailer axles forward, or you can transfer weight from the trailer axles to the drive axles by sliding the tandem axles back. If you don't have these options, you have to readjust your load.
Without requiring a permit, a standard five axle unit is permitted a gross weight of 80,000 lbs. Typically, this is defined as 12000 on the steer axle, 34000 on the drive axles, and 34000 on tandem trailer axles. You can have a gross of 40000 lbs. on the trailer axles if the trailer has a 10' spread between the axles, and the steer axle can gross up to 20000 lbs, IF the axle and tires are rated for it. However, the max gross weight of the vehicle remains 80,000.
20,000 lbs. statutory for each trailer axle, provided that there is a 10' spread between the axles. This does not affect the gross weight you are allowed.
With a ten foot spread, you can have up to 40,000 lbs. total on the trailer axles, but no more than 20,000 lbs on each individual axle.
Tandem means that first you hook the power sources to each other, then to whatever it is that's being powered - like the stoker and the captain on a tandem bike
You're talking about the trailer? Some specifics would be in order. On a tandem trailer, the axles are about three feet apart from each other. If you're referring to the distance between the trailer axles and the drive axles of the tractor, they're allowed to be a maximum of 41 feet apart, except in California, where they're only allowed a 40 ft. bridge between the two.
I would like to purchase scrap aluminum trailers 40 ft and up. Lawrence
No, each segment of a tandem breaker is what the breaker rating on the handle states. Tandem breakers are used when there is no space left in the distribution panelboard. You get an extra circuit by removing the full size breaker and installing a tandem breaker,
There isn't one. So long as the weights on each axle/set of axles are legal, that's all Barney cares about.
Different to equal-weight whcih gives the same weight, or importance, to each stock in a portfolio or index fund. Value-weighted method is placing heavy weight diffrently depending on the size of company's market value.
12,000 on the steers (can be up to 20,000 so long as the vehicle does not exceed the 80,000 GVW limit), and the drive and trailer tandems are permitted a total of 34,000 for each pair of axles. Trailers with spread axles are permitted up to 20,000 lbs. per axle for a total of 40,000 on the trailer axles, but again must remain within that 80,000 GVW limit.
