Tractor trailers weigh from anywhere from 15,000lbs-20,000lbs, with tractor about 15,000lbs-20,000lbs. So about 30,000lbs-40,000lbs unloaded. They can carry about 40,000lbs 50,000lbs. They cannot be over weight on any axle, which cannot be under 12,000lbs on steers, rear axles 34,000lbs, and on trailer axles, also have to be 34,000lbs. It can be under but not over. The max weight loaded is 80,000lbs Gross Weight. If weight is over the max on the axles or gross, the DOT can give a ticket up to $1 a pound.

If the trailer has a ten foot spread axle, up to 40,000 lbs. is permitted on the trailer axles, although the federal gross weight still may not exceed 80,000 lbs.

How would you describe an 18-wheeler What constitues a rig. Is it truck and trailer tractor and trailer or trailer and rig?

An 18 wheeler consists of a tractor (meaning something that pulls) and a trailer (meaning something that follows.) A semi tractor-trailer rig has a trailer that sits on top of the frame of the tractor on a coupling device called a "fifth wheel." The tractor has ten wheels with two on the front axle and four on each drive axle in the rear. The trailer has two axles with 4 wheels each. The tractor and trailer together are informally called a rig. Is that what you were after?

Depends on the type and size of the rig, but a typical tractor weighs 15,000# and a 53' enclosed van trailer weighs about 13,000#, for a total of 28,000 lbs. Most US highways have an 80,000 pound weight limit, so the load capacity or maximum net weight of a typical tractor-trailer is 52,000 lbs.

How do you buy repossessed tractor trailers?

What is the overall length of a tractor trailer rig with a 55 foot trailer?

Well there are no 55 foot trailers. The standard now days are the 53 foot trailers. Some companies have experimented with 57 foot trailers but they could ot be taken east of the Mississippi when I was driving. The total length varies depending on the rig that is pulling the trailer. The combination I believe is usally around 65-70 feet, could be a little less or a little more depending on the rig. Having recently conducted a study in California in hopes of changing the length law in this state, I measured 67 tractor trailer combinations. 57 of those combinations had measurements that fell between 73-75 feet. All combinations were made up of a conventioal tractor and a single 53 foot trailer. Hope this helps you.

How much do rig welders earn?

Depends on the context in which its used. Could be a "rig" on land or in water. Some jobs require "Riggers / Welders" who work with cranes and must be able to "rig" large loads as well as fabricate crane booms and spreader bars. "rig welder" is a vague term, most likely job specific.

Why do they call 18 wheelers semis?

It's short for "semitrailer". The entire rig is properly called a tractor-semitrailer. It's a semitrailer because it's only part of a trailer; it only has the back set of wheels (the front wheels under the cargo area are attached to the tractor, the part with the engine and the driver's cab).

Does the weight of the trailer count towards towing capacity?

Of course it does. If you think it is close, go to a truck stop with a scale A: weigh your whole rig (all 3 axles on the scale), B: just the rear axle of the vehicle and the trailer C: just the trailer axle. D: Remove the trailer and weigh your towing vehicle. Calculate: E: The loaded trailer ( A minus D) should not exceed the towing capacity rating for the vehicle or the weight rating for the trailer. The load on your rear axle with the trailer (B minus E) should not exceed the weight rating for that axle THIS IS VERY IMPORTANT: have you ever seen trailers swaying on the highway? this is very dangerous. Your trailer tung weight - the weight on the hitch (E minus C) , should be about 15% of the weight of the trailer. That bumber cannot exceed the weight rating of the hitch, but if it is too small the trailer can be very difficult to control.

If my tri axle dump truck has a GVW of 70000 can weigh up to that much what if I add a 20000 lb trailer what if I add a 25000 lb machine?

GVW means Gross Vehicle Weight. That's the maximum permissible weight of the truck plus the trailer (in the case of a combination rig) plus the load. Therefore...if you take your dump truck, hook a 20,000-lb empty trailer to it and put a 25,000-lb backhoe on the trailer, the truck needs to weigh less than 25,000 lbs if you want to remain legal.
