Check out the crazy suspension on these heavy duty moving trailers

In some cases, “moving” literally means moving the whole building. And the trailers used to haul these homes down the road feature a pretty impressive design underneath.

New Zealand-based Tidd Ross Todd (TRT) specializes in building equipment for the transport and construction industries. The company is particularly adept at building special trailers for moving large structures, including houses and bridges. TRT enjoys tackling tough problems like these, in keeping with the company motto: “Saying Sh*t Yeah Since 1967”.

TRT’s moving trailers feature independent suspension on multiple axles, distributed on the left and right sides of the trailer. To call it “suspension” is to underestimate it, however.

Each wheel has its own hydraulic cylinder and raises or lowers to meet the ground below. The whole trailer can be lifted to overcome obstacles or to balance itself on rough terrain. One side or the other can even be raised to allow the trailer to cut through slopes.

The trailer also has steering on each axle. This can be controlled automatically via sensors in the trailer hitch, which react to steering commands from the driver in the cabin.

Alternatively, the steering and hydraulics can be manually controlled by an operator with a remote control. This is typically used when navigating the trailer around a tight job site.

In this video from a recent move, we see a TRT trailer being used to move a house. Careful hands on the controls help guide the trailer under the structure on a rough, sloping site. Note how the wheels are raised and lowered as needed to keep the trailer level under the house.

All of this hardware comes in handy when trying to move a house hundreds of miles across the country. This can help lift the building over obstacles, reducing the need to remove street furniture along the way. Additionally, the fact that all wheels can turn allows the trailer to make tighter turns, reducing travel time and making route planning easier.

Most of us would simply look for another house or build a new one when moving. However, if you really want to take your home with you, you can always hire one of these trailers to get the job done.
