Ground-loading vehicle platform for pickup truck

A ground-loading vehicle platform comprising:

• a platform support frame consisting of at least one horizontal member and at least one vertical member;
• at least one pivot in engagement with the at least one horizontal member;
• a platform member configured to support at least one vehicle, the platform member comprising a subplatform extensibly mounted to the platform member for extending a length of a rear end of the platform for supporting a vehicle thereon, wherein the subplatform has an adjustable height at least between a deployed height providing a top surface of the subplatform to be coplanar with a top surface of the platform member and a lower retracted height, and wherein the subplatform is retractable under the platform member when at said retracted height;
• at least one pillar rotationally connected to a pin member positioned on the at least one vertical member, wherein the at least one pillar extends perpendicularly from a front end of the platform member;
• and
• a structural body supporting a mechanically operating lifting system configured to be mounted to a pickup truck, wherein the mechanically operating lifting system is configured to slide and lower the platform member from a stored position over a bed of the pickup truck to a loading position on a ground surface by a rotation of the at least one pivot arm member.
