Abstract
A litter lift system includes a winch system and a lifting strap. The winch system includes a rotatable spool. The lifting strap has a first end, a second end, and an intermediate segment extending away from the lifting strap between the first end and the second end. The first end is coupled to the rotatable spool such that rotation of the spool in a first direction winds the lifting strap about the spool and rotation of the spool in a second direction unwinds the lifting strap from the spool. The second end defines a first lifting segment and the intermediate segment defines a second lifting segment. The first lifting segment and the second lifting segment are each forked to define two separate lifting loops.
Claims20
A litter lift system comprising:
- a winch system including a rotatable spool;
- and
- a lifting strap having a first end,
- wherein the first end is coupled to the rotatable spool such that rotation of the spool in a first direction winds the lifting strap about the spool and rotation of the spool in a second direction unwinds the lifting strap from the spool,
- the lifting strap having a second end, wherein the second end defines a first lifting segment,
- the lifting strap having an intermediate segment defining a second lifting segment, the intermediate segment fixed to and extending away from the lifting strap between the first end and the second end, and
- wherein the first lifting segment and the second lifting segment are each forked to define two separate lifting loops.
A vehicle, comprising:
- a frame;
- a vehicle body supported by the frame, the vehicle body having a floor, a roof, and a plurality of walls extending between the floor and the roof to define a passenger compartment therein;
- and
- a litter lift system positioned at least partially within the passenger compartment, the litter lift system comprising:
- a winch system including a rotatable spool;
- and
- a lifting strap having a first end,
- wherein the first end is coupled to the rotatable spool such that rotation of the spool in a first direction winds the lifting strap about the spool and rotation of the spool in a second direction unwinds the lifting strap from the spool;
- the lifting strap having a second end, wherein the second end defines a first lifting segment;
- and
- the lifting strap having an intermediate segment defining a second lifting segment, the intermediate segment fixed to and extending away from the lifting strap between the first end and the second end, and
- wherein rotation of the spool in the first direction raises each of the first lifting segment and the second lifting segment at an approximately equal rate.
A vehicle, comprising:
- a chassis;
- a vehicle body supported by the chassis, the vehicle body having a floor, a roof, and a plurality of walls extending between the floor and the roof to define a passenger compartment therein;
- a litter support system having a frame defined by two parallel channels;
- and
- a litter lift system configured to raise a litter received within the parallel channels away from the frame, the litter lift system comprising:
- a winch system including a rotatable spool;
- and
- a lifting strap having a first end,
- wherein the first end is coupled to the rotatable spool such that rotation of the spool in a first direction winds the lifting strap about the spool and rotation of the spool in a second direction unwinds the lifting strap from the spool;
- the lifting strap having a second end, wherein the second end defines a first lifting segment, and
- the lifting strap having an intermediate segment defining a second lifting segment, the intermediate segment extending away from the lifting strap between the first end and the second end, and
- wherein rotation of the spool in the first direction raises each of the first lifting segment and the second lifting segment at an approximately equal rate.
