Offloader systems

An offloader system comprising:

• a main support comprising:
• a main support body having a main ramp surface with a first edge having a first length, and
• a main cover extending around the main support body;
• a first auxiliary support comprising:
• a first auxiliary support body having a first auxiliary ramp surface with a second edge having a second length and a first side surface, and
• a first auxiliary cover extending around the first auxiliary support body, the first auxiliary cover hingedly coupled to the main cover along the first edge and the second edge so that the first auxiliary support is rotatable relative to the main support;
• and
• a second auxiliary support comprising:
• a second auxiliary support body having a second auxiliary ramp surface with a third edge having a third length and a second side surface facing the first side surface, and
• a second auxiliary cover extending around the second auxiliary support body, the second auxiliary cover hingedly coupled to the main cover along the first edge and the third edge so that the second auxiliary support is rotatable relative to the main support;
• wherein the second length is 20% to 40% of the first length, inclusive;
• wherein the third length is 20% to 40% of the first length, inclusive;
• and
• wherein the first side surface and the second side surface are separated by a fourth length, the fourth length is 20% to 40% of the first length, inclusive.

An offloader system comprising:

• a main support defined by a first edge and a second edge opposite the first edge, the main support comprising:
• an inner core comprising a foam and defining a cavity positioned at the second edge,
• a first sheet comprising a polymeric material, and
• a second sheet comprising the polymeric material, the second sheet coupled to the first sheet along a periphery of the first sheet and cooperating with the first sheet to form a cover, the cover extending around and enclosing the inner core to form an inflatable cushion;
• and
• a first valve coupled to the first sheet and the second sheet and positioned along the first edge, the first valve being in fluid communication with the inflatable cushion and configured to facilitate flow of fluid into the inflatable cushion.
