Abstract
A lifting system is described that allows a load to be lifted into and out of a bed of a vehicle on which the lifting system is mounted. The lifting system includes a rotational driving mechanism for rotating lifting linkages and causing a lifting platform to raise into the vehicle bed. The rotational driving mechanism may be driven by linear motion.
Claims (12)
1. A vehicle-bed mounted loading and unloading system comprising:
a lifting assembly comprising:
a support frame to be mounted on the truck deck and providing front and rear pivot points on first and second sides of the truck deck;
first and second lifting linkages each coupled to a respective side of the support frame and comprising:
a front lifting arm having a lower end pivotally connected to the respective front pivot point;
a rear lifting arm having a lower end pivotally connected to the respective rear pivot point; and a connecting arm having a front end pivotally connected to an upper end of the front lifting arm and a back end pivotally connected to an upper end of the rear lifting arm; and a rotational driving mechanism for providing a rotational force to at least one of the first and second lifting linkages; and a lift platform releasably connected to the lifting assembly comprising:
a lifting frame for supporting loads;
a lift support connected to the lifting frame and providing a connection above the lifting frame for connecting to the lifting assembly proximate the upper ends of the front lifting arms, the lifting frame rotatable about the connection; and a rotation-limiting connection for coupling the lifting frame to the lifting assembly proximate the upper ends of the rear lifting arms to limit rotation of the lifting frame about the connection when loading and unloading loads.
a lifting assembly comprising:
a support frame to be mounted on the truck deck and providing front and rear pivot points on first and second sides of the truck deck;
first and second lifting linkages each coupled to a respective side of the support frame and comprising:
a front lifting arm having a lower end pivotally connected to the respective front pivot point;
a rear lifting arm having a lower end pivotally connected to the respective rear pivot point; and a connecting arm having a front end pivotally connected to an upper end of the front lifting arm and a back end pivotally connected to an upper end of the rear lifting arm; and a rotational driving mechanism for providing a rotational force to at least one of the first and second lifting linkages; and a lift platform releasably connected to the lifting assembly comprising:
a lifting frame for supporting loads;
a lift support connected to the lifting frame and providing a connection above the lifting frame for connecting to the lifting assembly proximate the upper ends of the front lifting arms, the lifting frame rotatable about the connection; and a rotation-limiting connection for coupling the lifting frame to the lifting assembly proximate the upper ends of the rear lifting arms to limit rotation of the lifting frame about the connection when loading and unloading loads.
2. The system of claim 1, wherein the rotational driving mechanism comprises two rotational driving mechanisms, each connected to one of the lifting linkages.
3. The system of claim 1, wherein the rotational driving mechanism comprises:
a drive sprocket connected to one of the lifting linkages at one of the front or rear pivot point locations;
a free-wheel sprocket connected to the support frame;
a roller chain connecting the drive sprocket to the free-wheel sprocket; and a sliding drive connected to the roller chain between the drive sprocket and the free-wheel sprocket, wherein linear movement of the sliding drive is converted into rotation of the drive sprocket and a corresponding rotation of the lifting linkage.
a drive sprocket connected to one of the lifting linkages at one of the front or rear pivot point locations;
a free-wheel sprocket connected to the support frame;
a roller chain connecting the drive sprocket to the free-wheel sprocket; and a sliding drive connected to the roller chain between the drive sprocket and the free-wheel sprocket, wherein linear movement of the sliding drive is converted into rotation of the drive sprocket and a corresponding rotation of the lifting linkage.
4. The system of claim 3, wherein the linear movement of the sliding device is provided by a hydraulic cylinder having one end connected to the sliding drive and an other end connected to the support frame.
5. The system of claim 1, wherein the rotation-limiting connection maintains the lifting frame in a generally horizontal orientation.
6. The system of claim 5, wherein the rotation-limiting connection is coupled to the lifting assembly by a chain.
7. The system of claim 1, wherein the support frame comprises a left support structure comprising respective front and rear pivot points, and a right support structure comprising respective front and rear pivot points.
8. The system of claim 7, wherein the left and right support structures are connected together by one or more braces.
9. The system of claim 1, wherein the lifting frame comprises a platform with a flat surface.
10. The system of claim 1, wherein the lifting frame further comprises sides surrounding the platform.
11. A kit for a truck deck mounted loading and unloading system comprising:
first and second support structures to be mounted on respective sides of the truck deck, each support structure providing front and rear pivot points on first and second sides of the truck deck;
a pair of front lifting arms each having a lower end to be pivotally connected to a respective front pivot point;
a pair rear lifting arms each having a lower end to be pivotally connected to a respective rear pivot point; and a pair of connecting arms each having a front end to be pivotally connected to an upper end of a respective one of the front lifting arms and a back end to be pivotally connected to an upper end of a respective one of the rear lifting arms;
a rotational driving mechanism for providing a rotational force to at least one of the first and second lifting linkages; and a load platform releasably connected to the lifting assembly comprising:
a platform for holding loads;
a lift support of the platform to provide a connection above the platform for connecting to the lifting assembly proximate the upper ends of the front lifting arms; and a rotation-limiting connection for coupling the platform to the lifting assembly proximate the upper ends of the rear lifting arms to limit rotation of the platform about the connection when loading and unloading loads.
first and second support structures to be mounted on respective sides of the truck deck, each support structure providing front and rear pivot points on first and second sides of the truck deck;
a pair of front lifting arms each having a lower end to be pivotally connected to a respective front pivot point;
a pair rear lifting arms each having a lower end to be pivotally connected to a respective rear pivot point; and a pair of connecting arms each having a front end to be pivotally connected to an upper end of a respective one of the front lifting arms and a back end to be pivotally connected to an upper end of a respective one of the rear lifting arms;
a rotational driving mechanism for providing a rotational force to at least one of the first and second lifting linkages; and a load platform releasably connected to the lifting assembly comprising:
a platform for holding loads;
a lift support of the platform to provide a connection above the platform for connecting to the lifting assembly proximate the upper ends of the front lifting arms; and a rotation-limiting connection for coupling the platform to the lifting assembly proximate the upper ends of the rear lifting arms to limit rotation of the platform about the connection when loading and unloading loads.
