Abstract
Abstract A cargo handling apparatus is described for lifting, transporting and unloading cargo in connection with a vehicle, such as a pickup truck. The apparatus is fastened to the vehicle and has a separate platform upon which cargo is placed and attached while the platform is on the ground. An end of the platform then is raised by a winch and cable to a height approximately to the bottom of a boom assembly. The boom then is lowered slightly to a slope approximating the slope of the platform and attached cargo. The platform now is movable along the boom by the winch and cable, and finally, the boom is pivotable down onto the vehicle. All operations are controlled from a hand held unit.

Claim 1
Independent Claim
282 words
A cargo handling apparatus adapted for use with a preselected vehicle, having a load carrying area, to easily, smoothly and safely raise a cargo and deposit the cargo in the load carrying area on the vehicle for transporting to a desired location where the cargo is unloaded with equal ease, smoothness and safety, comprising: frame assembly means formed of a predetermined width and length to fit the load carrying area of said preselected vehicle and defining a predetermined distance above the ground; boom means mounted pivotally at one end and supported by said frame assembly means, including winch means with flexible means extending from an end of said boom means furthermost from said one end; separate platform means to support said cargo, so that said flexible means extends substantially unobstructed from said winch means vertically down to one end of said platform means when said platform means is separate from said boom means; and power means to adjust the position of said boom means and to operate said winch means; whereby said boom means is pivoted so that said an end of said boom means is past a vertical, said flexible means is attached to said one end of said platform means for raising said one end of said platform means, without encountering said vehicle, to a predetermined height equal to said distance above the ground, said boom means then is lowered to approximately 45 degrees, said platform means is pulled up onto said boom means by said winch means, and said an end of said boom means is lowered in a direction away from said cargo to a position in said load carrying area on said vehicle for transporting said cargo.
