Adjustable quick disconnect portable wheel chair ramp

Portable wheel chair ramps consist of a platform and ramp sections. The platform and ramp sections are sandblasted. Ramp sections have an extended adjustable legs, (U.S. Pat. No. 6,810,995.). Ramp sections have an extruded locking mechanism underneath that connect one section to others using a specifically designed tube and a configurated J hook. Rails are then connected to extended adjustable legs of ramp sections and secured to each other with an end post and an angle piece of aluminum, then bolted together, insuring the rigidity of the railing system to comply with codes. Bolting the rails together with an inner handrail gives a continuous railing system for the purpose of individuals using a wheel chair to traverse the ramp. Inner rails are secured to the railing system and the leg posts with a bolt, this rail runs the entire length of the ramp on both sides.
