Broshuis trailers for crane trucks
Trailers to be towed behind a truck with a crane are often different to the standard. A crane truck is generally longer than a normal truck. To stay within the legal size limit (combination length), the length of the trailer is modified (the longer the K-dimension of the truck, the shorter the cargo bed length becomes). Because our trailers are built according to customer wishes, we can respond optimally to what you need behind your crane truck.
Swing radius and front extension
Because the crane is placed on the back of the truck, the gooseneck of the trailer needs to be modified to enable the trailer to swing freely. The front extension of the trailer is modified for this.
In the image below, the swing radius is indicated by ‘R’ and the front overhang with ‘FE’.
In a truck with multiple axles, this swing radius needs to be larger, as a result of which the distance from the kingpin to the rear side of the neck becomes longer. For a semi low loader, this longer neck also means a shorter low bed.
One of our advantages is that we are also able to achieve a short front overhang with steered trailers. #OnlyBroshuis
Aside from the changes above, a crane on the truck sometimes also means that the chassis of the truck needs to be reinforced. This is often done by placing an additional frame on top of the chassis. In this way, the coupling height of the truck becomes higher. If this height cannot be lost because cargo needs to be placed on the neck within the legal height limit, we can provide trailers with a low gooseneck. In this way, the height loss of the truck is compensated by the low neck of the trailer.
