The A-frame will be used to transfer up to 35,000 lbs of marble and granite to the truck. Then it will be lifted onto the flatbed and lowered onto the bed. The reason it has to be flat is that if the marble is not securited bedded down, any slight twisting moment on the slab could result in a...
I want to know if it's feasible to use a folding wheel design that will allow me to have the wheels drop down when the framework is lifted off the truck (not unlike landing gear) and develop a mechanism for retracting the wheels when it is placed on the truck? An alternative method would be to...
I am designing an A-frame structure that needs to be capable of rolling on a concrete surface, but that has a the ability to retract or fold the wheel into the hub when it is loaded onto a flatbed truck.
The A-frame structure will weight approximately one ton and the load will weight approx. 15...
