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.
The weight of a trailer loaded with bricks depends on several factors, including the size of the trailer and the type of bricks used. Standard bricks typically weigh about 4.5 pounds each. For example, if a trailer holds 500 bricks, it would weigh around 2,250 pounds, not including the weight of the trailer itself. Always consider the full weight capacity of the trailer and local towing regulations.
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.
To convert tandem loads to triaxle loads, you need to assess the total weight supported by the tandem axles and then distribute that weight across the three axles of the triaxle configuration. Generally, a triaxle can support more weight due to its additional axle, allowing for better weight distribution and reduced stress on each axle. You may also need to refer to specific load distribution guidelines or regulations applicable to your region, as they can vary. Overall, the conversion involves ensuring that the total load does not exceed the legal limits for triaxles.
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.
Each trailer is very different. Range can be $100 - $3,000.
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,
Using helium in tires would have a minimal impact on the weight of a semi-trailer. Helium is much lighter than air, but the amount of helium in the tires is very small compared to the overall weight of the trailer, so the difference in weight would be insignificant.
