How to Determine Axle Position When Building Single Axle Utility Trailer The general rule when building a trailer is there should be a 60/40 percent split in weight when centering the axle. Sixty percent of the trailer weight should be placed forward of the axle for proper tongue weight.
How do you know where to put an axle on a trailer?
How to Know Where to Put Axle on Trailer Measure the length of the cargo platform or box of the trailer, ignoring the trailer tongue. Calculate 40 percent of the length of the trailer cargo area. Measure the calculated distance from the rear of the trailer and make a soapstone mark on the trailer frame.
How do I know what axle position to use?
To know how far back the axle needs to be moved, we want to subtract the trailer’s tongue weight from 10 percent of the total weight. Then we will divide this number by the total weight. Then we will multiply this by the distance from the tongue to the axle.
How far back should an axle be on a trailer?
For example, if your trailer is 84 inches long, you will want to start with your axle approximately 50-13/32 inches from the front of your trailer. The equation explained in the photo will help you adjust this distance for the correct location.
Why are trailer axles so far back?
Why are the axles on a horse trailer so far back compared to a flatbed or cargo trailer? Expert Reply: Since the rear won’t move as much with the axles placed further back, there isn’t going to be as much rocking back and forth on the trailer from their weight as they climb in.
What is an axle on a trailer?
In the most basic terms, the axle is a shaft that transfers the trailer weight and drive to the wheels. This simple-sounding shaft, though, may be the most complex part of the trailer.
How long should the tongue on a trailer be?
Trailer tongues need to be at least as long as half the tow vehicles width. Most cars and SUVs’ range between 5′ to 6 1/2′ so the minimum length of tongue needs to be half of this plus a little bit more (say 8-12″) to gain a margin of clearance when turning and to add stability to the trailer.
How long can a single axle trailer be?
The length depends on state. In California, the total length is usually 65 feet. The trailer length is 28 feet 6 inches and the motorized house length is 40 feet (38 feet if the trailer has a single-axle fifth wheel, and 40 feet if there are two or more axle fifth wheel).
How do you measure a trailer axle spread?
You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this harder to determine. You can also measure from common points in reference to the axle.
What is the axle spacing?
axle spacing means the measurement between the centers of the axles as measured from center-to-center of wheel hubs.
How do you measure rear axle spacing?
The spacing of a frame/fork is measured from the inside surfaces of the dropouts, where they come into contact with the locknuts of the wheel’s axle.
Can I add a third axle to my trailer?
To add your third axle, you cannot simply add a hanger spring and axle. You can keep your 35 inch spacing but you will need to relocate your hangers. You will need to add another equalizer of the same dimension as you have to each side and then add the same leaf springs and shackle straps as what you currently have.
Should your trailer be level when towing?
When towing, trailers should be level to improve stability, braking performance, and ground clearance. A level trailer will prevent poor towing characteristics, like sway, and uneven tire wear. Adjusting the trailer to be level is important for safety.
Is it better to have the trailer tongue higher or lower?
The trailer will tow better if the hitch of the trailer is 1.5 inches lower than the rear of the trailer, if it is properly balanced. I would raise yours some, but it is not imperative to be level, but the ball should never be higher.
Should a tandem axle trailer be level?
Level weight distribution on tandem axle trailers is imperative, and an absolute must with torsion axles. Towing high on multiple axles can shift additional weight to the rear axle(s) – resulting in dangerous excessive wear on tires and suspension components. It has even been known to cause braking problems.
How do I know if my trailer axle is out of alignment?
Look for any elongated holes where suspension is bolted/hanging. Elongated holes can cause things to shift from the proper positions. You can check axle alignment by measuring from the center of the coupler back diagonally to the center of one of the wheels. Then take the same measurement to the other wheel center.
Are trailer axles supposed to flex?
Expert Reply: Trailer axles are designed to have the bow in them that you described. This allows the axle to flatten out when it is loaded and have the proper camber. If your trailer loaded will weigh right at 3,000 lbs when loaded a 3,500 lb axle would be a great option.
What is axle alignment?
“Axles are aligned in a static position so that when the vehicle is operating dynamically, the wheels and tires are in an optimum position with the road surface,” he said. “That optimum position is whatever it takes to get best tire life and best traction.”Mar 1, 2013.
What is the difference between single axle and tandem axle?
A single axle trailer has a one set of wheels; a tandem axle has two sets of wheels. Simple counting can tell you which kind of trailer you’re looking at, which makes it easy to compare trailers and determine which one suits your needs best.
