Kwik lift auto repair ramp. This is an extendable steel ramp set for service cars. It includes the ramp and two cross bars intended to be used with jack stands to raise the vehicle even further.

NOTE: See the actual pictures for true representation of the rust on this set. The rust does not affect structural integrity but does make it more difficult to separate the pieces. Some grinding and painting would help.
NOTE++: This requires a full 8+ foot-trailer or pickup bed to transport. Total weight is likely 1/2 ton.
