Abstract
A lift for loading and unloading a truck. The truck has a loading chamber, a rear body portion and a chassis frame, and the lift has support posts mounted at an end and at each side of the truck at the rear body portion. A connecting member connecting the lower ends of each support post is provided. A drive moves the support posts in an upward and downward direction. A lift table has an opening formed in a portion corresponding to the chassis frame. The lift table is supported by the connecting member and is slidable on the connecting member in a longitudinal direction to the loading chamber thereby traversing the connecting member.
Claims23
A lift for loading and unloading a truck, having a rear end, sides, a chassis, and a loading chamber having a floor defining a plane, said lift comprising:
- movable support posts mounted adjacent the rear-end and at each side of the truck;
- drive means for moving said support posts in a direction substantially perpendicular to the plane;
- a lift table having at least one slit therethrough substantially in registration with One of a chassis frame and a longitudinal joist, the at least one slit having a width slightly larger than a thickness of a web portion of the one of the chassis frame and longitudinal joist and extending from a front end of said lift table relative to a forward end of the truck toward a rear portion of said lift table so that said lift table is divided into a plurality of panels each integrally connected together only at the rear portion of said lift table;
- and
- support means for supporting said lift table substantially parallel to the plane when said lift table is in a drawn out position, said support means comprising:
- a connecting member connecting a lower end of each support post and supporting essentially the entire front end of said lift table;
- and
- means for connecting a respective side of said lift table with a respective movable support post so that said movable support posts support both respective sides of said lift table.
A lift as defined in claim 20 further comprising:
- plural support members attached to the chassis frame;
- at least one pair of first and second arm members forming a parallel link mechanism, one end of each arm member being connected to a respective support post, the other end of each arm member being connected to a respective support member, each connection comprising a pivotal shaft-type connection being separated from adjacent connections by a predetermined distance;
- wherein
- said drive means drives at least one of said support posts and said parallel link mechanism.
In a lift for loading and unloading a truck comprising:
- support posts mounted at both sides of a rear end of a rear body;
- drive means for moving upward and downward the support posts;
- a lift table having a slit formed therethrough in a portion corresponding to one of a chassis frame and a longitudinal joist, the slit defining a width slightly larger than a thickness of a web portion of the one of the chassis frame and longitudinal joist and extending from a front end of said lift table relative to a forward end of the truck toward a rear portion of said lift table so that said lift table is divided into a plurality of panels each integrally connected together only at the rear portion of said lift table;
- and
- support means for supporting the lift table comprising:
- a connecting member extending in a longitudinal direction and connecting lower ends of the support posts to support esssentially the entire front end of said lift table when said lift table is in a drawn out position, said lift table being slidable on the connecting member in a direction transverse to the longitudinal direction of the connecting member;
- and
- arms connected to the support posts and provided at both sides of the connecting member as to protrude rearwardly, the arms supporting sides of the lift table.
A lift for loading and unloading a truck, having a rear end, sides, a chassis, and a loading chamber having a floor defining a plane, said lift comprising:
- movable support posts mounted adjacent the rear-end and at each side of the truck;
- a connecting member having plural ends each connected to a lower end of a respective support post;
- drive means for moving said support posts in a direction substantially perpendicular to the plane;
- a lift table having a slit therethrough substantially in registration with the chassis frame, said lift table being supported by said connecting member and slidable on said connecting member in a direction parallel to the plane;
- and
- a respective rearwardly protruding arm pivotally connected at each end of said connecting member for supporting said lift table, each said arm having a U-shaped cross-section for accommodating a respective side of said lift table, said arms being parallel with said connecting member when said lift table is contracted and being at an approximate right angle relative to said connecting member when said lift table is drawn out.
