ABSTRACT:
A loading or unloading platform is located and secured in a frame mounted beneath the bottom of a semi-trailer. The platform is removable from underneath the semi-trailer by releasing a lock and pulling the platform out from under the trailer after extension of the retractable wheels of the platform. The platform is then available for use in a locked position adjacent to any door of the semi-trailer. A ramp is used in combination with the platform. The ramp is located underneath the bottom of the semi-trailer in two spaced-apart mounting brackets, one mounting bracket for each end of the ramp. One mounting bracket is fixed in position and includes a lock for locking a bottom end of the ramp underneath the semi-trailer. The other mounting bracket includes a swivel turntable and a pivoting holder for engaging the top end of the ramp.
