Model "Trailer Tr4 MkII 8258” is build with LEGO® in scale 1:17,5 and motorized using LEGO® Power Functions. It is not build after a specific brand or type of trailer. This build represents a three axle detachable gooseneck lowboy trailer with liftable third axle.  This specific version of "Trailer Tr4 MkII” fits and works perfect with LEGO® Technic set 8258 Crane Truck. This LEGO® Technic set 8258 Crane Truck needs to be slightly modified. Free instructions on how to modify your set are available!

The trailer features: solid axle suspension on all axles, one set of lights, kingpin, mechanical parking break, gooseneck frame support, remotely controlled liftable third axle, remotely lowering and lifting of the deck and this model has many details.

This newly design and engineered trailer utilizes the same suspension as both "US Truck T1 MkII" and "US Truck T2 MkII". It uses LEGO® rubber belts and LEGO® rubber axle connectors.  Designing and engineering this trailer parts availability is checked. So it can easily be build in the color as it is, Yellow, but it can also be build in Red, Blue and Black.

This model is another custom design by Ingmar Spijkhoven AKA 2LegoOrNot2Lego that comes with building instructions and inventory/parts list. So, you can build it yourself!  To do so you can buy the Building Instructions. Early in the building process you will see what it is that you are building. You will be very excited from the moment you start the build of "Trailer Tr4 MkII 8258" till you finish it with a total number of parts of about 1450 pieces.

With this type of lowboy trailer the gooseneck is removed to make the deck accessible. Because the front part of the trailer rests on the surface the truck with the gooseneck still attached can drive off. In order to keep the gooseneck elevated at the correct hight is as a support. This support rests on the trucks frame.

The ramps can be lowered and any self propelled load can enter the trailers deck. With the trailer loaded and the load secured the gooseneck can be reattached. This is done by backing up the truck aligned with the trailer. With a support that rests on the trucks frame the gooseneck can be lowered of lifted to make sure it comes in place. Finally the deck can be lifted again and the gooseneck can be locked so it doesn’t go anywhere without the trailer itself.

What an interesting kit to build.
The size just takes over as it all fits into place.
Parts easily found through bricklink at reasonable prices. So much better sourcing the parts yourself rather than just opening a box. Just adds to the fun.
5stars and excellent alround from me.
