发明名称 Safety ramp and method for protecting hoses and conduits
摘要 An apparatus and method have been developed for protecting a hose or other utility conduit from damage caused by traffic crossing over such conduits. Substantially rectangular ramp units with covered conduit channels are interlocked to form an elongate safety ramp with a channel running the length of the ramp for receiving a conduit. The ramp units are interlocked to form a linear or branched safety ramp.
