*Note: For US states maximum height varies. East of Missouri river is 13 feet and 6 inches or 4.1148 meters and west of the Missouri river is 14 feet or 4.2672 meters. Alaska maximum height is 15 feet or 4.572 meters. This is only a rule of thumb and not exact. For example Oklahoma is 13′ 6″ or Colorado and Nebraska are 14′ 6″. Also some designated routes are approved for additional heights. Be sure to research any/all laws before attempting to ship oversize or heavy items. Shipping it legally can be tricky.

Maximum weight restrictions for trucking.

Learn more about oversize trucking and transport.

Each state or province has different regulations. The above is a North American average. Regulations for heavy haul and oversize trucking can be very complex once a shipment has been determined “heavy” or “oversize” and there is a classification system within each state that can even qualify a shipment as a “super load”. Once dimensions or weights exceed the legal maximums transport permits are required. Some shipments may require pilot cars or even pilot cars equipped with height poles or the trucking company may be required to have a route survey performed. It’s important to consult a professional before attempting to transport any objects, machinery or equipment that is oversize or over weight.

 

Know the legal limits anytime you transport a load.

Whether you are a professional truck driver or a novice with a pick up truck it’s always smart to know the laws. Public safety a big factor to consider when transporting large or heavy items. Public property should also be factored in as damages could crush you financially. Fines and possibly getting your vehicle towed and impounded are other factors to consider. Always consult a professional as well as local laws when considering transporting over dimensional or over weight shipments.

Removable goose neck trailer.

What is a removable goose neck trailer?

A removable goose neck trailer (RGN) detaches from it’s own goose neck which attaches it to the semi-truck. Detaching the equipment allows driveable machinery to be loaded onto the deck. The driver of the truck then backs up to the deck and re-attaches the removable goose neck with a hydraulic lift. Removable goose neck trailers are very popular and versatile as they can move heavy haul loads. Notice in the photograph below the extra axles. These additional axles evenly spread the weight of the heavy haul shipment throughout the road. This ensures the pavement is not damaged. Removable goose neck trailers save money because items requiring transportation don’t need a crane. Additional axles are easily added to this type of configuration. RGN shipments can be moved easily using our loadboard in order to get a freight quote.

removable goose neck trailer


Removable goose neck trailers were invented during the 1950’s and are great for transporting over weight, over height, oversize and over height shipments.

As we discussed above the front portion of this trailer detaches which allows the trailer to be lowered to the ground. This leaves a ramp to drive equipment on to. RGN shipments are typically driven onto the trailer.  RGN trailers can have up to 20+ axles so they can carry freight up to 150,000 pounds.

  • These are the maximums that can be loaded onto a removable goose neck trailer before trucking permits are required:
  • The maximum load weight is around 42,000 pounds.
  • The maximum well space provides about 29 feet of deck space.
  • The maximum width is 8 feet and 6 inches.
  • The maximum height of the load is about 11 feet and 6 inches.
  • The maximum overhang is determined by the laws in each state/province.

Learning removable goose neck basics.

Always be sure you clearly understand all of the state(s) laws, regulations, rules and limitations prior to shipping any type of load on a removable goose neck trailer. Hefty fines can be levied from breaking laws. Regulations in each state differ and you should fully research them prior to moving any load to make sure you are in compliance. Oversize and heavy-haul loads require specialized driver training and trucking permits in order to be transported. Always refer to the actual state issued permit for any discrepancies you may have. Be smart, be safe and know exactly what you are doing before doing it.

Accessories used with removable goose neck trailers.

Quite a few removable goose neck trailer accessories are available. In order to make loading/unloading easier as well as protecting the item that is being transported. In many cases the owner of removable goose neck (RGN) trailers may add ramps to the trailer thus making it easier and quicker to load/unload items. Especially farming equipment or dozers, loaders, back-hoes, trucks, tractors and scrapers or any specialized equipment that has tracks or wheels. One of the most popular accessories is tarps. Tarps provide protection for items that are being shipped and can cut down on the possibility of damages. Keeping insurance claims to a minimum is always a smart idea.

 

Removable goose neck trailers with additional axles.

Heavy equipment shipping is a demand that is increasing. As we grow so do our capabilities which usually means larger equipment. As you can see in our illustration above 5 axle removable goose neck trailers are in demand these days and the owner of one with the right customers can have a 5 axle removable goose neck (RGN) combination running team drivers pretty much year round.

Large equipment hauling on removable goose neck trailers.

​Flatbed oriented trailers are capable of hauling a very diverse range of items. While items like connex trailers, tiny houses and general freight can help keep a trucking company busy generating revenue the real purpose of removable goose neck trailers is hauling big, heavy, tall machinery and equipment. As we mentioned earlier the target market for removable goose neck (RGN) trailers is equipment and machinery that may be heavy but also tall. This is the key element that drives demand for this type of trailer.

What is a height pole?

WHAT IS A HEIGHT POLE?

A height pole or high pole or hi-pole is a measuring device that is precisely attached to the front of a pilot car vehicle that is used to measure the height of overhead obstructions during the transport of over-dimensional (tall) shipments by oversize trucking companies. North American states and provinces have laws that regulate and mandate when a height pole is required in order to transport over height shipments within their jurisdiction. To be in compliance with these pre-determined requirements trucking companies must determine if the shipment they wish to transport will require a height pole pilot car or a lead escort vehicle with a height pole installed before applying for a oversize trucking permit.

The photograph illustrated here is a typical example of what a pilot car vehicle might appear like when equipped with a height pole.  You can clearly see the measuring device affixed to the front of the vehicle as it is very tall. A height pole is typically made out of sections of fiberglass that are adjustable to meet the requirements by each state/province the shipment will be transported through. Typically the height pole will be adjusted to a height that is 6 inches (or 15.24 centimeters) taller than the shipment is when loaded onto the shipping trailer. Then once the actual transport of the item takes place the pilot car equipped with the height pole will proceed in front of the over-dimensional (tall) load being transported. If a driver of the pilot car equipped with the height pole (hi-pole or high pole) hears the fiberglass height pole hit any obstructions in the path of the shipment the operator will then immediately notify the driver of the truck transporting the shipment informing of the obstruction in order to prevent any damages to the shipment or the obstruction. When a height pole is properly mounted to the escort vehicle it is connected to the frame. If the height pole does happen to strike any objects the sound heard by the pilot car is very loud and distinct thus alerting the driver of the obstruction. It has been noted as recently as 2015 in excess of 169 million dollars in overhead obstruction damages were caused during that single year in the United States alone. So having these safety measures in place is most definitely in the best interest of everyone from the tax payer, to the safety of the motorists and the owner of the shipment being transported as well as the transportation company.


The importance of installing a height pole correctly.

There’s no such thing as cutting corners when installing a height pole on your pilot car. It’s extremely important it’s directly connected to the frame of your pilot car for two reasons:

  • Ensure it is sturdy, stable and not going to fall off of your vehicle.
  • So you can hear the sound it makes if it hits any obstruction. To do so properly it must be attached to the frame.

In order for the pilot car vehicle operator to properly hear the sound created by the height pole if a obstruction is hit it is imperative the device be properly and securely mounted to the vehicle in such a manner the bracket holding it is connected to the frame of the pilot car vehicle. In order to obtain the absolute highest quality from installing this device you may wish to make certain you are not adding sub-supports for your height pole when designing your attachment method.

Suggested methods of attaching a height pole.

While there are many different way to install a height pole on your pilot car vehicle we strongly suggest you locate a heavy-duty bumper grill made from heavy tubing such as you might see on law enforcement vehicles. If you are able to locate a front bumper/grill protector attachment you then have a few options:

  • The first would be to cut the top portion of the bumper guard off so your height pole can easily slide in/out of the pole. Make certain you devise a method than locks it in no matter how you decide to attach it.
  • The second option would be to locate a small piece of pipe the base of the height pole snugly fits into and weld this onto the bumper grill attachment.

This will require some planning, designing and fabricating on your part in order to weld the pipe in place so it stands perfectly vertical but well worth it if you wish to work with shipments that are over-height.

The bumper grill works so well due to the fact it usually connects with two bolts to your vehicle. The tubing these are constructed out of is not only heavy-duty but very close if not the same as the base of most height poles. So not only do it properly but efficiently as well.

Why is it so important to connect high poles to the frame of pilot car vehicles?

A good quality sound must be made if any obstructions are hit with the pole. You want to consider all of the other noises that occur when you are operating your pilot car vehicle. You’ve got the sound of your engine, the sound of your tires on the road as well as any 2-way radio chatter. Other sounds such as sirens, trains, air-planes etc. are frequent as well. Because the height pole is so important make sure if it does strike something overhead it clearly makes a loud sound. This will  instantly alert the operator by being indistinguishable from any other sounds or background noises.
