Claims14
A tailgate overload protection system for a dump truck, the tailgate overload protection system comprising:
- a wire configured to interconnect a rear frame and a tailgate arm of the dump truck;
- and
- a safety fastener;
- wherein the rear frame is connected to the wire via the safety fastener, wherein the safety fastener is configured to break first when a tailgate of the dump truck is overloaded, and wherein the safety fastener is configured to break when a predetermined force is applied thereto via the wire and wherein the predetermined force is lower than the lowest load capacity of any segment of a rear section of the dump truck.
A method for preventing damages on a dump truck, wherein the dump truck comprises a tailgate protection system comprising a wire configured to interconnect a rear frame and a tailgate arm of the dump truck, wherein the rear frame is connected to the wire via a safety fastener, the method comprising:
- providing a tailgate threshold force, wherein a force exerted onto a tailgate connected to the tailgate arm above the tailgate threshold force constitutes a risk of damaging the tailgate or the tailgate arm;
- and
- selecting the safety fastener such that the safety fastener has a shear strength that provides for the safety fastener to break when the force above the tailgate threshold force is exerted onto the tailgate or the tailgate arm;
- wherein the safety fastener is configured to break when a predetermined force is applied thereto via the wire and wherein the predetermined force is lower than the lowest load capacity of any segment of a rear section of the dump truck.
