We have modified the neck design of the low bed semi trailer by providing additional support as shown in the above picture so that sharp bends are avoided in primary structural members.
Actually when there are sharp bends the weight acting per unit area is more. This becomes a weak zone where the structure can shear. The area near the neck is more vunerable for one more reason i.e while fabricating this neck a lot of heat input is given in terms of welding and cutting the members to achieve the given shape of the low bed trolley.
This heat input induces stresses in these areas. When subjected to load the primary members fail because of the heat affected zone; this problem could have been addressed by stress relieving techniques. However the cost of the trailer would go up and this becomes a prohibitory factor.
In the said scenario our design will take care all the above factors. This will help us avoid use of additional steel that is wrongly used by local fabricators to strenthen the primary members while manufacturing trailers.
