• a track supported by said base and selectively locked with and unlocked from said base, and when said track is unlocked from said base said track is mounted for linear movement along said base;
• an arm configured to support a cot, said arm selectively locked to and unlocked from said track, and when said arm is unlocked from said track, said arm is mounted for selective linear movement along said track;
• wherein when said arm and said track are locked together, said arm and said track move together along said base over a first range of motion, and when said arm and said track are unlocked, said arm is movable along said track over a second range of motion;
• a trolley supporting said arm, said trolley movable along said track to thereby move said arm along said track, and said trolley configured to selectively lock said arm to said track;
• and
• a latch, said latch releasably locking said trolley to said track, wherein said base is configured to selectively unlock said latch from said trolley.

An ambulance cot loading and unloading apparatus for loading or unloading into an emergency vehicle, the emergency vehicle having a cargo area and an opening into the cargo area, said ambulance cot loading and unloading apparatus comprising:

• a base for mounting to a deck of the emergency vehicle;
• a track supported by said base and selectively engaged with and disengaged from said base, and when said track is unlocked from said base said track is mounted for linear movement along said base;
• an arm configured to support a cot;
• and
• said track having a first latch to selectively lock to and unlock from said arm, and said track having a second latch to selectively lock to and unlock from said base, wherein when said arm is unlocked from said track, said arm is mounted for selective linear movement along said track, and when said track is unlocked from said base and said arm is locked to said track, said arm and said track move together along said base,
• wherein said track is movable along said base between a fully retracted position and a fully extended position along said base, and said arm is movable along said track from a fully retracted position to a fully extended position along said track, further comprising a latch to lock said arm to said base when said arm and said track are in their fully retracted positions.
